The C:N аnd N:P rаtiоs аre impоrtant prоperties of organic amendments and crop residues. (10 pts) Describe what should happen to N in amendments when the C:N ratio is 8:1 vs. 45:1, and a representative example of an organic amendment or a crop residue for each of these two ratios. (10 pts) Describe how the N:P ratio in amendments differs from the N:P of crop removal, and the two possibilities in terms of meeting crop N and P demand when fertilizing exclusively with organic amendments (note: you cannot meet both crop N and P demand exactly when using only organic amendments, so one of the two nutrients will be off when you meet the demand of the other nutrient).
