1.	explain how the use of fertilizer has improved crop production ??
Answer» A survey of U.S. crop production estimated that average corn yields would decline by 40 percent without nitrogen (N) fertilizer. Even greater declines would occur if other macronutrients, phosphorus (P) and potassium (K) were also limited. Numerous long-term studies have also demonstrated the contributions of fertilizer to sustaining crop yields. For example, long-term studies in Oklahoma show a 40 percent wheat yield decline without regular N and P additions. A long-term study in Missouri found that 57 percent of the grain yield was attributable to fertilizer and lime additions. If we use the fertilizers in a proper amount not in a large amount then it will be good to increase the crop yield.
