Steps to Develop a Nutrient Management Plan for Sunnyside Acres Using Snap-Plus

1. Steps to Develop a Nutrient Management Plan for Sunnyside Acres Using Snap-Plus Requirements for Assignment FISC Soil and Crop Nutrient Management Step 1 – Based on the field map describe a soil sampling strategy for each field that will result in the taking of the proper number of soil samples. (Hint: Remember 5 acres per sample or fewer samples if both P and K are excessively high. See UWEX Pub. A2809 p. 3 for guidance on sample numbers for excessively high fields). On the Snap-Plus farm screen select crops to be grown in 2012 and county, fill in your name and address, write a short narrative about what you are doing. Rotation starts in 2009 and 2012 is the last year of the 4 year rotation sequence. (C=corn grain, Cs=corn silage, A=Alfalfa, As=alfalfa seeding, S=soybean) Step 2 – On the field screen enter field ID, acreage, county (Sauk), major soil type (dominant soil if 10% or more of field area), slope (A:0-2%, B:2-6%, C:6-12%, D: 12-18%), set slope length to 300, set slope below field to 0-2%, measure distance to perennial water “blue line” stream, and start rotation for all fields in 2012. Step 3 – Enter average soil test data (given in slide #5) for each field on the soil test screen. Note: Use separate screen for each field. Step 4 – Create an inventory of on-farm nutrient resources. (Legume N credits and manure credits). Consider that all rotated alfalfa stands are poor and cut to less than 8 in. No second year alfalfa credits. Manure is not stored (daily haul) and all manure is surface applied. Manure type is semi-solid stalk bedded. Step 5 – Develop a manure allocation strategy using method shown in class for crop year 2012 using a P-based strategy that applies no more than 75 lb P2O5 (25 t/a). Note fields with manure spreading restrictions (no winter spreading if 300 ft. from stream, manure must be incorporated if otherwise spread w/in 300 ft. of stream. Step 6 – Based on the crop rotation for each field show the nutrients provided by manure and legume forage and show the final adjusted N, P2O5, and K2O recommendation for the 2012 crop year. Step 7 – List the Phosphorus Index for each field in 2012 comparing all no-till or all fall chisel/disk. Fill in blanks and print out or send as pdf to complete the assignment.
