Manure Management Plans Using the values in the table, calculate spreading rates for either raw manure or compost. As a reminder, the average horse produces 10 tons of manure per year, composting reduces this by half. | Nitrogen (1b/ton) Phosphorous (lb/ton) Potassium (lb/ton) Raw manure 8.73 1.67 4.37 Compost (sawdust) 9.6 4 5 You have 2 acres of pasture to spread your manure on and 2 horses producing manure (annually). The pasture requires 65 lbs of N/acre, 80 lbs of P/acre, and 100 lbs of K/acre. 1) How many tons of raw manure can you spread based on nitrogen requirements? 2) How many tons of raw manure are produced per year? Do you have enough land to spread your manure on
