No N credit from mature rye.. Biomass-N available for sweet potatoes includes 20 lb/ac contribution as residual -N from beans in the preceding year. **See attached nutrient management worksheets for additional nutrient recommendations. Rates reflect total N requirement in any particular calendar year for the crop. N added by summer cover is 50% is available to double or following crop. Spring canola N recommendation includes 30 lb/ac N for following bean crop. ***Additional input N required after credits. Negative lb/ac N values represent potential rollover N contribution to following crop. ****Litter application rate based either on N rate required for maintenance of "LOW" P risk or P removal rates of crops. P removal rates in double crop years reflect P removal rates for both crops summed (e.g. canola and beans).
