| Abstract: | As agriculture develops in Jiangsu Province, potassium deficiency in soil is caused by soil potassium decrease at the rate of 2. 3 mp/kg per year. It is envisaged, in light of potassium balance in soil, total yields of grain and cotton for successive years in the province and application rate of both potash and compound fertithers, that the amount of inorganic/chemical potash fertilizers needed by Jiangsu for the future years should be increased. Considering the desperate shortage of K, several wars for the improvement of soil K were suggested. |
