摘要

US fertilizer consumption for the 1988--1989 year was 44.9 million tons of material-an increase of less than one percent from the previous year. The average plant nutrient content of all fertilizers decreased slightly as total plant nutrient consumption declined from 19.61 million to 19.59 million tons of N, P(sub 2)O(sub 5), and K(sub 2)O. Total nitrogen consumption increased one percent to 10.63 million tons, while P(sub 2)O(sub 5) use decreased by less than one percent to 4.12 million tons. Potash consumption declined from 4.97 million tons to 4.83 million tons K(sub 2)O-a 2.8 percent decrease. Consumption patterns varied widely from state to state as weather conditions adversely affected fertilizer application even with significant increases in total planted crop acreage. Illinois, Indiana, Iowa, Minnesota, and Ohio reported a decline in total plant nutrient application while several of the southeastern states registered an increase in consumption. Nutrient levels in mixed fertilizers remained unchanged as slight gains in the nitrogen and P(sub 2)O(sub 5) content were offset by a decline in K(sub 2)O. Consumption of ammonium polyphosphate solution (10-34-0) and monoammonium phosphates increased 9.2 percent and 12.8 percent respectively, while diammonium phosphate (18-46-0) use was 2.4 percent below last year. A general increase in the use of nitrogen materials was reported with the exception of nitrogen solutions which declined 2.1 percent from 1987--1988. Urea consumption rose almost 2 percent. ammonium nitrate was up 8.1 percent, and ammonium sulfate recorded a 9.5 percent gain in consumption. Anhydrous ammonia use was only 35,000 tons above last year. This document contains a state by state listing of individual fertilizer consumption rates, numerical data only.
