Straw is the only organic material available in significant quantities
to most rice farmers. About 40 percent of the nitrogen (N), 30 to
35 percent of the phosphorus (P), 80 to 85 percent of the potassium
(K), and 40 to 50 percent of the sulfur (S) taken up by rice
remains in vegetative plant parts at crop maturity.
