Hello, Harford County! The warm days of spring are upon us—and now so are the stink bugs! Like many others I know, my house was the perfect overwintering site for many of these little critters who are now waking up and getting ready to march back into the fields. Stink bugs have been a pest of concern to farmers and homeowners alike. Many are wondering if 2013 will be a mild year, like 2012 was, or if we should prepare for another year like 2011 or 2010. I had the opportunity to attend a regional Brown Marmorated Stink Bug (BMSB) Conference in April, where researchers from USDA and several Mid- Atlantic universities presented their findings. Although there is still more to be done, the past few years’ work has yielded some enlightening results. Are traps effective? Most traps that are currently available use a pheromone from a different species of stink bug to attract BMSBs. In research trials, traps containing this pheromone were only effective in late season (after mid- August). Researchers have identified and successfully synthesized a BMSB-specific pheromone, which has proven to successfully attract BMSB all season. However, it will not be available commercially until 2014. Another research study showed that fields with traps had significantly more damage than fields without traps, even though the traps did catch a large number of BMSBs. This is likely because the pheromone actually attracts more BMSBs into the field. Thus, it may be advisable to locate traps in a “sacrifice area” in order to contain damage to one spot. This will also make it easier to treat with pesticide since most of the BMSBs will be congregated in one area.

Hello, Harford County! The warm days of spring are upon us—and now so are the stink bugs! Like many others I know, my house was the perfect overwintering site for many of these little critters who are now waking up and getting ready to march back into the fields.

Stink bugs have been a pest of concern to farmers and homeowners alike. Many are wondering if 2013 will be a mild year, like 2012 was, or if we should prepare for another year like 2011 or 2010.

I had the opportunity to attend a regional Brown Marmorated Stink Bug (BMSB) Conference in April, where researchers from USDA and several Mid-Atlantic universities presented their findings. Although there is still more to be done, the past few years’ work has yielded some enlightening results.

Are traps effective? Most traps that are currently available use a pheromone from a different species of stink bug to attract BMSBs. In research trials, traps containing this pheromone were only effective in late season (after mid-August). Researchers have identified and successfully synthesized a BMSB-specific pheromone, which has proven to successfully attract BMSB all season.

This will also make it easier to treat with pesticide since most of the BMSBs will be congregated in one area.

A “Grow It, Eat It, Preserve It” program presented by UME Carroll County

Although the methods of hydroponic fodder production date back to the 1930's, there is renewed interest in hydroponic fodder as a feedstuff for sheep, goats, and other livestock. Hydroponics is a method of growing plants without soil. Only moisture and nutrients are provided to the growing plants. There are many advantages to hydroponics. Hydroponic growing systems produce a greater yield over a shorter period of time in a smaller area than traditionally-grown crops. There is a reduction or exclusion of pesticides and herbicides because the plants are in a more protected growing environment. Hydroponics is a year-round growing system that produces a consistent quantity and quality of plant material, regardless of outside weather. Fodder (livestock feed) can be grown hydroponically much the same as vegetables, flowers, and other plants. Hydroponic fodder systems are usually used to sprout cereal grains, such as barley, oats, wheat, sorghum, and corn, or legumes, such as alfalfa, clover, or cow peas. Barley is the most commonly grown forage, because it usually gives the best yield of nutrients (4). Forage mixtures are another option. A hydroponic fodder system usually consists of a framework of shelves on which metal or plastic trays are stacked. After soaking overnight, a layer of seeds is spread over the base of the trays. During the growing period, the seeds are kept moist, but not saturated. They are supplied with moisture and nutrients, usually via drip or spray irrigation. Holes in the trays facilitate drainage and the waste water is collected in a tank for recycling. The seeds will usually sprout within 24 hours and in 5 to 8 days have produced a 6 to 8 inch high grass mat. After the mat is removed from the tray, it can go into a feed mixer or be hand-fed to livestock. Livestock will eat the whole thing: seeds, roots, and grass. There

is minimal waste. Livestock may not eat the fodder initially because it is novel, but they soon learn to eat it with relish. While it is possible to grow hydroponic fodder in a n y b u i l d i n g , including a garage or

b a s e m e n t , a greenhouse is ideal because temperature, light, and humidity can be precisely controlled. Efficient, year-round production of green fodder is not possible unless environmental conditions are optimal: approximately 70°F, 60 percent humidity, and 16 hours of light. For this reason, hydroponic growing systems usually require significant investment. Hydroponic fodder systems come in a range of sizes and capacities. Large fodder sheds may produce several tons of fodder per day, whereas a mini-fodder system may produce only 125 lbs. per day (3). It is possible to build your own system or a "turn-key" system can be purchased from a commercial company. Investments range from a few hundred dollars to six figures.

As feed for livestock Fodder sprouts are tender and young, the equivalent of fresh spring grass. As such, they are highly palatable and nutritious to all types and classes of livestock. On an as-fed basis, hydroponic fodder compares favorably with other nutritious feedstuffs. At the same time, sprouting changes the nutritive characteristics of the grain. Enzymes breakdown storage components into more simple and digestible fractions; for example, starch to sugars, proteins to amino acids, and lipids to free fatty acids. There is an increase in fiber and some vitamins and a decrease in phytic acid, an antinutritional compound (11). There is a reduction in total energy. The increase in protein percentage is due to the dry matter loss . In fact, the downside to hydroponic fodder is its high moisture content. According to various forage analysis reports (3), the dry matter content of hydroponic fodder is only 12 to 15 percent, compared to almost 90 percent in (unsprouted) grains and hays (1). Even corn silage and haylage have considerably more dry m a t t e r t h a n s p r o u t s ( 1 ) . If you do not consider its high moisture content, the per pound price of hydroponic fodder seems very economical, around $0.06 per pound (or $120 per ton) (3). Without further analysis, this sounds like a great way to reduce the cost of feeding livestock. But when the wet cost is converted to a dry matter basis, feed cost becomes very high. At 12 percent dry matter

(DM), wet feed that costs 6 cents per pound actually costs 50 cents per pound of dry matter. This is considerably more expensive than most other feedstuffs, as shown in the tables below.

Because of its low dry matter content, the cost of nutrients in hydroponic fodder is also considerably more expensive than other feedstuffs. Nutritional requirements of livestock are based on dry matter intake. If fed to livestock at a rate of 2 percent of their body weight (a common recommendation), hydroponic fodder will only meet a fraction of most animals' nutritional requirements, especially the higher producing ones. Thus, the fodder, while excellent feed, is only a nutritional supplement and an expensive one at that. Full feeding of sprouts is usually inappropriate due to

the high moisture content of the feed, the high cost of the feed, and the scale which would be needed to produce sufficient dry matter (11).

Animal performance The companies that market hydroponic fodder systems make all sorts of claims about green fodder as a superior livestock feed: better gain, improved fertility, earlier heat cycles, improved fleece quality, improved immunity, better behavior and temperament, less manure, etc. Few of these claims have been substantiated or proven to be repeatable in experiments (5,11). Over the years, in many different countries, and with different species (mostly cattle, pigs, and poultry), research trials have been conducted to assess the performance of livestock fed hydroponic green fodder (11). Across the many trials, there has been no consistent advantage to including green fodder in the diet of livestock, especially when it replaces highly nutritious feeds, such as grain (5,7). Even if there are benefits to hydroponic fodder, the benefits are usually outweighed by the costs. Research is conflicting as to whether sprouting improves or reduces dry matter digestibility as compared to the raw grain. In a 2012 journal article, Iranian researchers reported no increases in quantity or quality of dry matter and nutrients with sprouting (10). While the companies claim that you'll get a 6 to 10-fold increase in weight from a pound of unsprouted grain, they fail to mention that the increase (in weight) is almost all water (5,11). At the same time, there is a strong need for more trials to determine the potential feeding value of hydroponic fodder, particularly with sheep and goats. Studies conducted in Italy in 2009 produced conflicting results with regards to milk production and animal welfare (2,8). Another aspect that needs to be investigated is potential changes in the final product (meat and milk) as a result of replacing some of the

animals' traditional diet with green fodder. Other challenges One of the biggest challenges to producing hydroponic fiber, especially commercial quantities, is mold (5, 11). Moldy sprouts can decrease animal performance and result in animal deaths (5, 11). Pre-treatment of seed with a sterilizing agent (e.g. hydrogen peroxide) is one strategy for preventing mold. Good hygiene in the system is also important. The growing

trays should be cleaned between crops with a chlorine based cleaning solution (11). Hydroponic fodder production requires a lot of labor. Time is needed to soak the seed, make up the nutrient solution, transfer the grain to the trays, load the trays onto the shelves, check the fodder daily for growth, remove the sprouted grain from the trays, wash and sterilize the trays, and feed the green feed to the livestock. Automation will reduce labor requirements, but may substantially increase investment costs. In order to create a controlled growing environment, it can require considerable energy to grow hydroponic fodder (5). Solar power could be used to provide electricity, especially in remote, rural areas or third world countries.

Advantages of hydroponic fiber Hydroponic fodder has several environmental advantages over conventionally-produced fodder. Hydroponic fodder makes very efficient use of water (4,5,11). There is little waste water, as animals consume the recirculated water along with the feed. Since production is hydroponic, there is no leaching of nutrients into the environment. Hydroponic fodder production requires considerably less land to produce livestock feed. While hydroponic fodder is not likely to become a major source of feed for commercial livestock, it may be feasible under certain circumstances. Dry and drought-prone regions. Hydroponic fodder production is probably best-suited to semi-arid, arid, and drought-prone regions of the world. By growing fodder indoors, crop failures would no longer be a risk. Good quality forage could be produced year-round. Feed supplies would be insured. Scarce water resources could be allocated more efficiently (4). Limited land. In places where land values are extremely high or land is simply not readily available, hydroponic fodder has obvious advantages, as it can be produced in a small footprint. Because the fodder is produced continuously, there is no need for long-term feed storage and no nutrient losses that can be associated with feed storage. High alternative feed costs. While this article clearly shows that hydroponic fodder is considerably more expensive than conventional feedstuffs, it assumes that

conventional feedstuffs are available and priced competitively. There are many locations in which this is not the case and hydroponic fodder could be more competitively priced, especially if animal performance is improved, due to unknown nutritional factors in the green fodder. Small-scale producers. Requiring smaller amounts of fodder, small-scale producers may be able to build their own fodder systems for a few hundred dollars. When the investment is low and labor is unpaid, the cost of hydroponic fodder is more reasonable. Non-ruminants. Hydroponic fodder may be best-suited to non-ruminants (horses, rabbits, pigs, and poultry) who would benefit more from the changes in the feed due to sprouting (e.g. less starch, more sugars) as compared to ruminants (sheep, goats, and cows) who are less efficient at digesting high quality feed (6). Hydroponic fodder seems ideal for horses, though the research is lacking. A study with rabbits showed no detrimental effect to replacing up to 50 percent of the commercial diet with green fodder (9). Organic. Hydroponic fodder production seems particularly well-suited to organic producers (6), who already pay high prices for feed or have difficulty sourcing organic feedstuffs. Cereal grains can easily be sprouted in accordance with USDA's Certified Organic Program.

In the future As competition for land and water increases and feed prices continue to rise, hydroponic fodder could become a viable option for more livestock producers.

The phrase “nip the problem in the bud” probably had its beginnings in

agriculture, and it certainly applies in early season corn management! Across

the U.S., early season weed management is critical to stand establishment

and protecting yields. And in the Mid-Atlantic region, where more growers

are practicing no-till, slugs are becoming a major issue. As part of its mission

to enhance the health, management, and production of corn crops through

quality, science-based information, the Plant Management Network has

published two new early season management webcasts in its “Focus on

Corn” resource: “Slug Management on Corn,” by Dr. Ron Hammond, and

“The Importance of Early Season Weed Management in Corn,” by Dr. Mark

Loux, both from the Ohio State University. These presentations are open

access through the end of June, 2013. These and other “Focus on Corn”

Presentations can be viewed at www.plantmanagementnetwork.org/foc.

Mark your calendars for the University of Maryland Webinar series! As part of Responsible Horse Ownership Week, sponsored by the Maryland Fund

for Horses, a variety of topics will be presented at 12:00 pm each weekday. All webinars will be recorded and placed on our website at extension.umd.edu/horses/resources/recorded-webinars for future viewing.

Harford County Weed Control Program

The Harford County Weed Control Program, in cooperation with the Maryland Department of Agriculture, is available to assist farmers in controlling noxious weeds on their properties. Noxious weeds in Maryland include thistles, Johnsongrass, Shattercane, and multi-floral rose; by law, these weeds must be controlled. The Harford County Weed Control Program will provide hand gun spot spraying for these weeds in pastures, crop fields, fence rows, building lots, and non-crop areas. The spray charge for farm properties is $45.00 per hour plus material. For more information, contact Nathan Anderson, coordinator, at 410-776-1526 or Jim Calao, MDA Representative, at 410-841-5920.

MDA’s Sensitive Crop Locator Launched

The Maryland Department of Agriculture has launched a new online mapping application, called a “Sensitive Crop Locator,” where pesticide applicators can see locations of crops sensitive to pesticide damage so they can take extra precautions to prevent drift, especially from herbicides, when spraying on nearby properties. Crops sensitive to damage include grapes, tomatoes, organic farms, tobacco, livestock, nurseries, and vegetables, among others. The map can be accessed from the MDA website, www.mda.maryland.gov, under “Hot Topics.” The map includes the name and address of the grower; the type of crop/commodity produced; contact information; and the specific location where each crop is grown. Commercial growers who want their crop and/or commodity listed can submit an application to MDA for each field to be listed on the website. For more information or to obtain an application, contact MDA’s Pesticide Regulation Section at 410-841-5710.

An electronic Buffer Zone Calculator is now available in EPA’s online Soil Fumigant Toolbox. The EPA developed this new tool to help soil fumigant applicators, growers, and enforcement personnel determine the buffer zone distances now required by soil fumigant product labels per label changes that became effective on December 1, 2012. The Buffer Zone Calculator is specific to each fumigant product and is based on look-up tables on the product labels. A guide for applicators explaining how to calculate buffer zones manually is also available in the Soil Fumigant Toolbox. To access these online tools, visit http://www.epa.gov/pesticides/reregistration/soil_fumigants/index.htm.

The next webinar in the Woodland Stewardship Education, Woodland Wildlife Series will be

“Ecology and Management of Young Forest Wildlife,” presented by Tom Mathews, habitat biologist from The Wildlife Management Institute. The decline in young forests and early successional environments has led to a decline in several important species, such as the American Woodcock. A high-speed Internet connection is required to participate. It is suggested

to connect 10-15 minutes before the webinar begins: connect.moo.umd.edu/umeforestry and log in as a guest.

“Planning for the Invasion: Control Measures for Emerald Ash Borer” will show municipal and county officials why they need to begin the EAB planning process as the invasion continues to spread throughout the state. The workshop will feature a hands-on demonstration of control techniques. This meeting will count for MD pesticide applicator recertification (categories 2 and 3A) and 5 MD/DE Master Logger CE credits.

Pre-Sidedress Soil Nitrate Testing: Crucial for Corn!

When growing corn grain or corn silage, soil nitrogen levels are very important for crop health and yields. Fertilizer recommendations, generated for a field that had a previous forage legume crop or manure application, assume a significant nitrogen contribution from the previous crop or manure application. Nitrogen is not a stable compound and there are many factors that can affect the amount that is actually present when the plant needs it.

The PSNT test takes the guess work out of nitrogen availability. This test determines how much nitrate nitrogen is present in the soil at a critical time. When the results indicate that the nitrogen level is satisfactory, the grower is saved from any more financial inputs. However, when nitrogen levels are found to be too low, nitrogen can be side-dressed at a rate to ensure an adequate crop.

Do your crop recommendations depend on a nitrogen credit from an organic application or a previous forage legume crop? Are you applying less than 50 pounds of nitrogen per acre in your starter fertilizer? If this scenario describes your corn field, it is highly recommended that you schedule a PSNT study to evaluate the nitrogen levels at this critical time.

Qualifications for PSNT testing: 1) Corn silage or corn grain is being grown.

2) Manure or biosolids have been applied this year or in the past two years, OR a forage legume was grown in the previous year. 3) Less than 50 pounds of commercial fertilizer nitrogen per acre was applied prior to testing.

PSNT is not applicable when: 1) More than 50 pounds of commercial fertilizer nitrogen has been applied to the field. 2) Commercial fertilizer has been the only nutrient source. 3) Irrigation is used.

When should this test be done? This test must be run when the corn is between 6 and 12 inches tall. If the corn is over 12 inches tall the test cannot be completed because results will be invalid. It is recommended that you let your nutrient management advisor know now that you will want this test done to ensure the advisor’s availability. It is also recommended that growers alert their advisors prior to the 6 inch stage. Corn grows quickly during this critical time, and scheduling can be challenging.

For questions on the PSNT test or to schedule testing for your fields, call Tricia Hoopes, Nutrient Management Advisor, at the Harford County Extension Office, 410-638-3255.
