Understanding Today’s Agriculture, AGRI130 Guest Lecture #7- Livestock Industry

On October 21, 2019 Mr. Dan SEVERSON spoke to the class on Delaware’s Livestock Industry. He covers the large-scope of the industry and the varied number of animals that are cultivated in agriculture.

Less than 2% of the U.S. population is involved in agriculture- a farm is any family that makes $1, 000 a year from agriculture. 98% of farms are family-owned and account for 87% of all agricultural value generated.  In Delaware, more than half of the farms are less than 50acres. More than half of farms have sales that generate less than $50, 000 in profit.   $3.5 million is generated in  direct-to-consumers in products and Delaware is the #1 state in the U.S. for value of products per acre. Delaware is also the #1 producer of lima beans in the U.S.

In the U.S., the livestock industry occupies .5mil acres land, with 500, 000acres in farms accounting for 40% of the gross domestic product.  With an average of 200 acres per farm, the industry generates about $8 billion in profit for agriculture.

Before going into the specifics of the Delaware livestock industry, Mr. SEVERSON gave the class a quick history overview. In 1914 WW1 takes shape & so begins the birth of agricultural extensions. In the 1930s Depression & Dust Bowl hit. And in 1939 WW2 starts, encouraging farm hands go to war. When the farmers return, they bring training & technology. No young man is willing to work for $0.50/week when they might earn $7/day at a factory.  In1950, Ammonium Nitrate fertilizer increases crop yields, aiding in a 265% increase in production and decreasing inputs by 2%

As a result of the wars ‘advancements’ the average annual per capita consumption of meat has changed over the years- beef, pork, and lamb have decreased while poultry has increased. 29% of Delaware’s land area is planted in corn & soybeans, and most of that produce goes towards the poultry industry as chicken feed. Goat & veal consumption has not been tracked ‘til recently. In the U.S. family food costs on average represent just 9.7% of a households income, that food typically consisting of what is most affordable, safe, & abundant. Compare that percentage to Russia’s average family spending 14-15% of their income, or the average Ethiopia n family spending 45%.  Much of that reduction in cost is due to the way that the meat is produced.

In Delaware there are 235 beef farms with 14, 000 cows/calves between them. Many of the cows are fed a Total Mix Ration (TMR) for more efficient and tailored nutrition. An example of a Delaware cattle farm would be Power’s Farm in Townsend, Delaware. Cattle are often the topic of Animal Welfare discussions.

Pork is soon to be vertically integrated. Swine production, Mr. SEVERSON notes, is a subject taught by UD’s Dr. Lesa GRIFFITH. Hogs may be raised farrow to finish, farrow to feeders, or feeders to finish. When keeping pigs, it is important to note white pigs are prone to sunburn, making the black breed Berkshire better for bacon. Part of the processing of hogs involves a scalding trough to skin the pigs, which Mr. SEVERSON notes is very hard to do. A popular value-added product made from pork is, ‘Artisan Scrapple.’   Mr. SEVERSON interjects the lecture to pose a question to the class on why pork shoulders are referred to as, ‘Boston Butt’.  When no one is able to provide an answer, he moves on.  Conducting a quick search after the fact define the pork shoulder is the ‘skinless, boneless upper part of a pigs front shoulder’.  A common cut, a quick Google search notes the name came from barrels the pork was shipped in and the region that made the cut popular.

Sheep are typically raised for wool. He notes that ‘Hair sheep’ are a type of sheep with wool that falls out.  The upcoming Delaware Agricultural Week in January 2020, a Maryland farmer with a sheep milking operation is slated to come.

Goats are raised for three things- Angora, milk, and meat.  There is no certified meat & milk facility in Delaware. In New Holland PA, the 2nd largest goat auction in country is held- Texas hosts the biggest auction.  The U.S. cannot support it’s ethnic population’s demand for goat meat, namely Islamic, Jamaican, & Jewish where goats are used for celebration. Mr. SVERSON says that goats are browsers like deer which eat above their heads.  The reason for it’s lack of broad popularity might be because goat meat doesn’t marble. Mr. SEVERSON proudly mentions that he received $280 for small (60-80lbs) goat in New Holland, where the price is based on the amount of meat. While attending the National Goat Conference in Montgomery, AL, where ice cream and cheesecake are popular forms of value-added goat products for a niche market. Lotions & soaps are easier in Delaware without a certified dairy.

Dairy is dying in the U.S.  In Delaware there were once 80 dairies, which decreased to 50, and now just 21 dairy farms operate today with 4 creameries- Woodside, UDairy, Hopkins, & Vanderwende Creamery. Natural by Nature & Hy-Point are the remaining processors. Farm fresh, homemade ice-cream is a popular commodity. Mr. SEVERSON notes Amish youth prefer construction to milking with it’s regular hours and consistent work. Whole milk contains 3.25% milk fat, while skim milk contains just 1%, but there is no raw milk available in Delaware. To generate a profit, dairy cow numbers are increasing- it takes 1000 cows minimum to make profit. For farms that are struggling, the cows are either moved to farms or shipped to different states & countries.

Other livestock farmers may keep for commercial production include bees, bison, alpaca, llamas, rabbits, water buffalo, deer, chickens, turkey, & emu. Mr. SEVERSON informed that class that he was unwilling to raise alpaca or llamas because they look ‘strange’ to him…

Lastly, Mr. SEVERSON discussed growing agricultural trends in the livestock industry. The number of farms is increasing while overall farm size has been cut in half- total production covers 8, 000 acres in Newark. The industry is also seeing a growing number of young farmers.  Farms and CSA’s are becoming increasingly diversified and catering to niche markets.  Many of these smaller farms are selling value-added products to direct markets. 10 current GMO crops include, corn, soy beans, cotton, papaya, squash, tomatoes, potatoes, canola, alfalfa, & sugar beets

The future of the livestock industry depends on new technology like GMO’s and robotics for labor, and investment in the next generation to cater to the environment, government regulations and animal welfare. Mr. SEVERSON states he has seen an increase in young females without and agricultural background pursuing knowledge to enter the industry. It takers 3-4years to establish a farm working with grants for funding. Mr. SEVERSON often conducts experiments on his own farm first. With that, he informs us of the skills and traits needed to work for the Extension agency. The following soft skills are preferable- listening, compassion, working with others and reading them. Other skills include agricultural skills, professional skills, & education.

Understanding Today’s Agriculture, AGRI130 Guest Lecture #6- Horticulture/Greens Industry

On October 16, 2019 Ms. Valann BUDISCHAK & Tracy WOOTTEN spoke to us on the Horticulture/Greens Industry.  This was the first guest lecture where the guest speakers were actually at the Georgetown campus, instead of the Newark campus.  Each speaker took turns, giving information on their professional journey as well as current information on the industry around the state.

First to speak was Ms. WOOTEN. She informed the class that she had an extensive background in agriculture, with her grandparents having farmed ad she herself growing up on a farm.  She majored in Plant Science and Vegetable Education to become a horticulture agent for home horticulture.  She earned a BS in Plant Science where she observed 1/3 of the samples that were brought in suffered from ‘environmental problems’, i.e.,  problems due to how the plant grew on the weather , rather than disease or bacteria.

Next, Ms. BUDISCHAK spoke on her background.  She took a very different path that Ms. WOOTEN, working at Black and Decker for 14years and commuting between Baltimore and New York before deciding to make a change.  She decided to work for the Delaware Nursery and Landscape Organization before managing grants for the Delaware Dept. of Transportation (DelDOT) and then becoming an extension agent for the University of Delaware.  She then volunteered for the Botanic Garden of which she eventually became director.

After those brief biographies, the two speakers told us about nurseries.  First, that nurseries are usually selling products for the home garden- over 60% of sales a container plants.  Most nurseries are located in Maryland, though there are a few noteworthy establishments in the first state.  Many nurseries are plug and container nurseries.  Many nurseries sell floriculture crops of bedding and garden plants- the biggest purportedly in Lanesboro, PA.  Cut flowers may even be sold at CSA’s.

A nursey might sell broadleaf evergreens, trees, and shrubs- ‘ball and burlap’ evergreens that begin as cuttings.  A garden nursery might sell field or container plants, plants for garden store and centers, and zero-scaping for low-water, native plants.  Sod and turf nurseries may sell bent grass- used on golf courses- or tall fescue and Kentucky Blue- used for home lawns. Sod generates $13.8 billion in revenue.

Other retailers might earn revenue by selling videos and how-tos for independent garden centers.  Others my reach consumers through radio shows, displays, and unique offers.

Certain garden centers specialize in particular services. The Gateway Garden Center for example, specializes in ponds, as landscape, providing consumers with the service of install and maintenance.  Another garden center might only market major brands like Proven Winner brand, sell only annuals, or sell directly from growers. Sposato Landscape is one of the top three landscaping business in the US, located right here in Delaware. Sposato Landscape has implemented a container rental program where last seasons’ planters may be replaced according to consumer.  Other noteworthy garden centers include Coast Garden Center, RSC Landscaping, Ronney’s Garden Center, Lakeside Greenhouse, & Bess’ Buds.  These garden centers will aid consumers with the name recognition of plants and provide care instructions and ‘How-to’ tutorials. Though landscaping is a big industry there are a small number of garden centers.

There is a growing market within the industry for indoor plants.  Landscapers will go into large corporate buildings and office parks to maintain or change out potted plants.  Landscaping is a very science-oriented field. However, in addition to helping to design and build, a landscaper may also be expected to maintain by handling mowing, pest, and invasive control, fertilization, lighting, and water features. A landscaper may also use soil conservation techniques such as stormwater management, irrigation, and hardscaping, or by assessing plant health.  One such technique, accessing the health of plants, namely trees, is handled by Delaware Arbor Care.

Those jobs are not without risks however.  While working on some landscape maintenance, a Mr. Steve JOHNSON, a nationally-known plant pathologist from New Jersey dies via tree limb.    The limb fell from a pine with shallow roots due to the sandy soil of the area.  The pine was part of a stretch of trees in a homeowner’s property that posed a risk to the people living and working there.  Because of this, insurance had the rest of the trees taken down.

Landscaping is a large component of ‘Land Management’, particularly of parks, schools.  The largest landholder in Delaware is DelDOT.  DelDOT’s responsibilities include enhancing highways with warm season grasses & meadows.  DelDOT does this by conducting minimal invasive management in the roadside, planting pollination strips flanked by mowed edges to cut down on labor.  These mowed edges show the public that maintenance is indeed ongoing, while giving a less intensely manicured look that a simple mowed strip would provide.  These plantings help curb the spread of invasive weeds like Japanese Knotweed, though the speakers note the mowed turf itself is not so healthy as water runs over it as opposed to seeping into the water table. Creating rain gardens & bioswales is an effective solution, as these improve water quality by filtering run-off.

In addition to highways, DelDOT also has a part in maintaining railroad tracks.  By maintaining the vegetation around the tracks they prevent obstruction and mitigate fire risks by cutting back encroaching plants to prevent ‘railspark fires’, which pose a risk to farmers and can burn crops.  The risk of fire also allows them to impose burning bans.  They will also scan for and remove invasive weeds.

Lastly, DelDOT contributes to the management of parks and recreation areas, like sportsfields.  Replacing turf is often cheaper than replacing mature trees and shrubs, as such, sod is a big component of volume purchases.  When designing and maintaining these fields there is a choice to be made between cool and warm season turf grasses or simply synthetic groundcover. Warm season grasses grow with rhizomes & stolons that knit together & create a smoother playing surface than cool season grasses, which grow clumped in bunches and spread via seed.  To keep the fields in optimum condition, they must be aerated, especially in high-traffic areas such as those found in front of goals, where compaction of the soil causes sand to crust on clay pockets.  To amend the soil, compost may been used.

To conclude, the lecture ended with the speakers informing the class on the various in-state opportunities for anyone who might be interested in pursuing landscaping.  To begin, it is helpful to know certain definitions such as annual, perennial, and bi-annual.  An annual plant grows in one season, i.e., Impatiens plants, while a bi-annual plant has a two-year lifespan, and lastly, a perennial dies and comes back, for example, the invasive Japanese Knotweed where pieces of the plant may break off and it’s underground runners can generate a new plant.  In Delaware, a license is required to sell plants, but for the average homeowners, there are tools to inform them of the best ways to manage their properties.  For example, a rain garden cannot be created from, ‘wet spots on the lawn’, but rather, must be able to drain.  This information and more is available from Delaware Livable Lawns, a program that helps homeowners and lawncare professionals mitigate run-off from nutrient applications from drifting into waterways.  In addition, they also have 2.5 month internship gardens.  For professionals, there’s the Delaware Nursery & Landscape Association (DNLA) at https://www.dnlaonline.org/.

Mr. Walter Edwin ‘Ed’ KEE on DE Ag and its importance as a food shed

On September 16, 2019 Mr. Ed KEE spoke to us on Delaware Agriculture and it’s importance as a feed shed.  The talk began with a bit of bio provided by both Prof. ISAACS and Mr. KEE, who shared a brief synopsis of his education and his ties to the University of Delaware’s continued work in the advancement of modern agriculture.  He stated that although UD became a land grant college in 1869, it wasn’t until the 1990s, when Dean Harry HAYWARD initiates the university’s purchase of $20, 000 worth of campus-adjacent farmland, that the Agricultural department started to make great strides- with the help of Dr. Bill MITCHELL, a WW2 veteran and extension agronomist.

Mr. KEE’s eight year tenure as Delaware’s Secretary of Agriculture, and two published works on the history of UD’s Agricultural Extension and Carvel Research Center, meant he had the background to give the class an in-depth picture of Delaware farming from the Colonial Days to today- including an interesting a related anecdote into Prof. ISAACS’ ancestry to illustrate the tenacity and determination  required of farmers.

From the Revolutionary War to the early 1800s Delaware primarily exported wheat.  After the completion of the DE Railroad in 1859 and the DuPont Highway in 1924 Delaware is able to improve the ways in which food is transported, shipping produce as canned goods in water or brine.  Many canneries are built around Delaware to process vegetables and fruits like tomatoes, peaches, and strawberries, but also ‘fruits of the sea’ like oysters, employing many individuals to move shipments from one point to another.  One cannery, the Stokely-Van Camp Cannery, was an early example of early agribusiness and the thought process behind environmental accountably.  The cannery, and other processors like it, would discard bean husks and effluent directly into the canals and waterways they were built near, clogging and polluting the watershed with excess nutrients and detritus.  This myriad number of canneries, mills, and factories would decrease from hundreds, to a mere two that remain today- PicSweet and Hanover- large companies that bought up smaller ones for better brand recognition.

The processors of the early 1900s did well, but the farms that provided them with product were rarely operating at peak efficiency.  Mr. KEE, citing Prof. ISAACS family line as an example, stated that most small farmers before WW2 would barely eke out 30 bushels of corn year after year, only just making a profit, but continuing to grow anyway.  It wasn’t until after WW2, when farmers embraced new technologies such as Henry WALLACE’s Pioneer Seed Co. seed stock and hybrid varieties, that they were able to increase their yield to 80 bushels.  Similar scientific advancements occurred with poultry, dairy, and other forms of produce.

The increasingly high yields and technological advancements in agriculture have made the farming field one that requires a  consistent, regulatory environment to turn a profit.  Through increased education, business procedures and regulations, farming has improved not only for the farmer, but also the consumer.

As stated by former Guest Speaker Ms. Georgie CARTANZA and Professor ISAACS, Delaware’s unique geographic position places most of it’s farms within eight hours driving distance to 1.1 million people, or 1/3 of the U.S. population.  76% of the state is open space, with ≈2/3 of that amount dedicated to farmland- ≈800 farms.  Of the 41% of the land area dedicated to farms- a total of 115, 000 acres- a total of ≈30% is permanently reserved through the AgLand Preservation Program, which was established in 1995.  The AgLand Preservation Program is a core feature of Delaware’s Agricultural economy, providing a steady and reliable market for farmers.  Through the AgLand program, land can be given to the state for preservation in perpetuity, or sold by the farmer to another farmer so the property remains apart of the Agricultural System.

Another program Mr. KEE shared with the class was the Young Farmers Program.   Mr. KEE haunted earlier that many farms are small farms of about 30-50acres.  Unable to compete with the ‘Big Ag’ industry for a larger share of the profits, about 40% of those farmers have off-farm income generated from other jobs such as teaching, factory work, or school bus driving.  The Young Farmers Program provides $500, 000 for a  qualified young farmer at 0% interest for 30years.

In order to help farmers young and old, make larger profits, many states have increased efforts to educate the public on farming as well.  Unlike the post-WW2 farmers, many modern-day consumers tend to be resistant to the innovations made in farming.  State Universities like UD try to educate to public on current farming practices.  Such practices discussed in class included Integrated Pest Management, used to identify and target specific pest to employ a targeted and controlled response that generates as little perceived amount of environmental harm possible; the use of Center-Pivot Irrigation Systems, irrigation that can be moved and monitored remotely via a cell phone for the optimum application of water.  Many more practices went unmentioned due to time constraints, but the need for greater public education regarding agriculture was greatly emphasized.

The lecture  closed with a discussion on the cultivation of hemp and the controversies surrounding a potential future cash crop.  Hemp might be harvested for CBD oil or fibers, though its legality is still not consistent across the U.S.- particularly by the FDA as food additive.  With and uncertain future and an unidentified market, many farmers might embrace the crop from and ethical standpoint, but can’t financially absorb the costs to grow it without a guaranteed profit.  Mr. KEE spoke of a group of Hollywood investors that approach a family farm of several generations to grow 1000 acres of hemp for them to process and ship.  The farmers agree to take the risk, but only if they were paid upfront.  The anecdote served to illustrate the balance between farmers and consumers, and how consumer demand and existing markets play a critical role is what is produced and how much.

 

 

CRISPR/Cas9 System

CRISPR-Cas 9 is a system that enables geneticists and medical researchers to edit parts of a genome by removing, adding or altering sections of the DNA sequence. Cas9 is a protein that is programmed by small RNAs to cleave DNA at the DNA strand where a scientist wants it to cut. The Cas9 is complexed with both a crRNA and a separate trans-activating crRNA in order to achieve the site-specific DNA recognition and cleavage. From this scientist can change the genes in the genome of a cell by introducing new genes into the sequence. CRISPR-Cas9 was discovered in adaptive immunity in select bacteria and archaea that enabled the organisms to respond to and eliminate invading genetic material.

This system or technology is better than other biotechnology since it is more accurate and is less likely to result in an error. The reason this is more accurate is it targets the specific spot in the sequence where the new genes need to be added. This is different than the other method of using chemicals or radiation to cause mutations. By using chemicals or radiation you were affecting the entire genome and could get a mutation you didn’t want since it was up to chance. Currently the CRISPR-Cas9 system is the fastest, cheapest and most reliable system for editing genes.

For a more in-depth look into it you can go to https://www.neb.com/tools-and-resources/feature-articles/crispr-cas9-and-targeted-genome-editing-a-new-era-in-molecular-biology which goes into the biology of it and explains all the types of RNA that are used in the system.

Newark Farm Tour

This previous Saturday, I spent time at the University of Delaware farm. I was so intrigued to see how this farm is able to teach students hands-on techniques in a manner that is safe and understandable. I was so amazed at the fact that dairy cows are taught where they are to feed and they are smart enough to retain  that information and store it in their memories. I also really enjoyed how honest the farm manager was. He didn’t sugar-coat any type of information that we should know and made sure we knew to hold ourselves accountable for our actions. Walking through the farm was such a different experience than being on main campus. Everything is so calm, whereas main campus is always bustling. Seeing the mini versions of the chicken houses was also interesting, especially because we got to compare it to the full size version at Georgie’s farm. Overall, I very much enjoyed this field trip, especially the UDairy!
