Abstracts: In ancient time, agriculture was more or less sustainable due to regular organic fertilization. Due to various economic constraints, farmers are forced to apply agrochemicals that give higher returns resulting in relatively high N input and a coincidental decrease of other nutrients including K. This situation is accompanied by negative K balance for many agricultural regions and indicates only a short- term consideration. A long term neglect of K would result in a non-sustainable situation for crop productivity.
