Dynamics of Potassium in Paddy Soils is an exciting new book for all those concerned with rice (Oryza sativa/japonica). Response of rice (T. aman and Boro) to potassium (K) application was studied under pot and field conditions with different levels of K. Soil solutions and rain, and irrigation waters were analyzed for K. Terrace soils released more K than Old Brahmaputra floodplain soils. The Q/I relationship showed that the equilibrium exchangeable K (EK0) and labile K (KL) of terrace soil were higher than floodplain soils. The potential buffering capacity (PBCK) was higher in floodplain...
