Balanced Crop Nutrition: Fertilizing for Crop and Food Quality

Abstract

Abstract: Globally the ratio of N:P2O5:K2O changed from 2.5:1.3:1 in the 1980s to 3.6:1.4:1 in 2002 as N consumption outstripped that of K. Regardless of their decreased nutrient consumption, developed countries maintained a modest increase in agricultural production. Positive and similar growth rates for agricultural products and nutrient consumption prevail in developing countries, but with the use of a 35 % higher nitrogen (N) to potassium (K) ratio than in developed countries. The outcome of a
