Soil loss must be determined as part of the PMT equation. RUSLE2 is one option that you can use to determine soil loss. Begin the installation Purchasing a copy of NuMan Pro 5. Contact Emileigh Lucas for an order form erosso umd. Tech Support Help with software is just a phone call away.

This publication is available in PDF format only. Delaware, Pennsylvania, Maryland, Virginia, and West Virginia, and Virginia, the five states in the Mid-Atlantic region, all require Certified Nutrient Management Plans to be completed for certain agricultural programs. The Mid-Atlantic Regional Nutrient Management Handbook is a revision and update of the former nutrient management training manual for the Chesapeake Bay watershed Nagle et al.

Updated A: Yes, manure must be addressed in the plan. You will need to determine the quantity of manure deposited on the pasture and also the quantity of manure collected.

If some will be used on a family garden and some will be exported, an estimate of both quantities is needed in the plan.

The client should keep a sign-up sheet handy and ask those exporting manure from the operation to record their name, address, phone number, and amount of manure taken just in case there is ever a question during an MDA inspection.

Choose reg P rem at the bottom of the scenario page in NuMan Pro. Bottom line - the manure rate is capped at the P-removal rate or 50 pounds of PAN per acre, whatever comes first. How much of a nitrogen credit do crop combinations warrant? Posted February 10, A: Typically the oats will winter-kill and form a vegetative mat under the crimson clover or hairy vetch. The nitrogen credit for the crimson clover and hairy vetch will depend on the amount of above ground biomass present at the time the crop is killed.

This in turn is a function of how long the crimson clover or hairy vetch is allowed to grow. Consult the table below for nitrogen credits based on typical spring weather in Maryland. Is it appropriate to take a nitrogen N credit when soybean yields are poor? What is a reasonable N credit? Posted November 8, A: The range of credits in the University of Maryland Extension guidance assumes a "respectable" soybean crop. If the soybean crop yield was low due to environmental factors such as drought, flooding, disease, or insect infestation, it can be assumed that the N credit should be less.

Source: Dr. What kind of N credit should I take for it? Posted July 9, A: Chilean nitrate is nothing more than sodium nitrate, a highly soluble inorganic compound.

All of the N will be available the year of application, and therefore no N credit should be taken in subsequent years. The crop was taken off as silage. Should any nitrogen credits be taken for the beans? Q: My client raises vegetables. Do I need to give nitrogen credits for green beans? Posted June 6, A: No.

Green beans are a short season crop that receive nitrogen fertilizer at planting. The N fertilization suppresses the plants' ability to fix nitrogen; therefore a nitrogen credit is not taken. Q: I am writing a nutrient management plan for a farm that received biosolids last year.

I know that I need to enter this information into the NuMan Pro history so that the appropriate nitrogen N credits are assigned. The biosolids applicator provided a list of all of the materials applied to each field.

Which organic N value should I enter if biosolids from multiple treatment plants were used on the same field? A: There are a few things to remember when entering biosolids information into the NuMan Pro history. If multiple biosolids products were applied, use the following process to determine which biosolids product to enter into the history: Enter each of the biosolids into the organics list in NuMan using the organic N from the MDE PAN Rates Table.

Apply each biosolid on the field at the N-based rate. The biosolid that can be applied at the highest application rate is the one you would enter into the history. This will be the product that provides the least amount of N credit on the field.

This product is selected to minimize the potential for applying inadequate N in any part of the field for the growing crop. The operation has 13 horses on 2 acres of land. He calls the area "pasture" but I'm not so sure. When I visited the farm in April there was not much growing; however, the owner claims that in the summer the area is covered with grass.

Should I assume the area is a pasture and provide a nutrient recommendation for grass for this client? Posted August 12, A: The rule of thumb for stocking density for horses is 2 to 3 acres of pasture per horse. Stocking rates considerably higher than that can lead to loss of vegetated cover, particularly if the horses have continuous access to the area. Such areas would be considered heavy-use areas or sacrifice areas, not pastures.

As such, no nutrient recommendation would be made. A: The pre-plant fertilizer recommendations sustain the crop through the first cutting. After the first cutting, maintenance recommendations should be provided. Posted November 8, A: New cultivars are constantly being introduced into Maryland. The table below summarizes the information about the new cultivars that is needed to develop a nutrient recommendation. Q: A client of mine grows currants. Posted November 8, A: Currants Ribes are similar in growth habit and fertility requirements to brambles.

Tissue samples should be analyzed and nutrient recommendations made using the bramble tissue norms and fertility recommendations in NM-5 , "Nutrient Management for Tree Fruits and Small Fruits. Should I use the recommendations for pears? Posted November 8, A: Asian pears are quite different from European pears in their management. Asian pears need to be pruned and hand-thinned for large, high quality fruit.

More than 50 varieties have been propagated, and they differ in their susceptibility to fireblight. Choose cultivars that have some resistance to fireblight and fertilize them like fireblight-resistant European pears. The fireblight status of some common Asian pear varieties is listed below. Posted July 9, A: The NuMan Pro software contains pre-plant nutrient recommendations for Christmas trees these recommendations are for the year in which the trees will be planted.

Should I use the alfalfa recommendations or the spring oats recommendations? Posted July 9, A: Emphasis should be placed on meeting the alfalfa's nutrient needs because as a perennial crop, it is a longer-term investment. Therefore, use the spring-establishment alfalfa recommendations. Other publications addressing turfgrass fertility can be found on the Maryland Turfgrass Council website.

Record Keeping Field Management Records Booklet This booklet is a free tool to help make crop, pesticide and nutrient management recordkeeping easier. It contains space to record crop information, management practices and nutrient applications on a field-by-field basis. Also contained in the booklet are common seeding rates for some agricultural crops and yield calculation formulas.

To order your recordkeeping booklets, please e-mail Elizabeth Abebe or call and leave your name, mailing address, and the number of booklets needed. Soil Sampling and Testing Q: I have heard that arsenic mimics P in soil tests and can falsely elevate P levels in results. Is this true? Posted March 18, A: At one time the ascorbic acid-molybdate blue method was a popular choice for assessing P levels in soil samples. If samples were not specifically treated to remove arsenic, then yes it would interfere with accurate P determinations.

However, most labs now use the inductively coupled plasma ICP spectrometer and interference is not an issue. Q: Is it good practice to take soil samples on fields that have recently received organic or commercial fertilizer applications?
