Fertilizer K and P requirements for rice (Oryza sativa L.) can be determined with site-specific
nutrient management (SSNM) using estimated target yield, nutrient balances, and yield …

Potassium (K) availability in soils is largely governed by their mineralogical composition.
The extent of weathering of primary K‐bearing minerals, the chemical pathways through …

Fertilizer use in Indian agriculture is skewed towards nitrogen (N) and phosphorus (P), and
farmers generally neglect potassium (K) input ignoring K requirement of crops. We …

The aims of the present study were to provide scientific bases for rational use of crop straw
to substitute chemical potassium (K) input. The effects of potassium fertilization and straw …

Conventional soil tests are commonly used to assess single soil characteristics. Thus, many
different tests are needed for a full soil fertility/soil quality assessment, which is laborious …

Despite removal of potassium (K) by crops in large quantities, often exceeding that of
nitrogen (N), K fertilization has long been neglected compared with N and phosphorus (P) in …

Present research was undertaken to understand the effect of long-term potassium (K)
fertilization@ 0 kg (K 0) and 80 kg (K 80) K ha− 1 on the quantity/intensity (Q/I) parameters …

Straw return is an effective way to improve crop grain yield and potassium (K) use efficiency
by increasing soil K content. However, the effects of straw return on soil K supplying …

Extraction methods of exchangeable and non-exchangeable K were combined with data
obtained from quantity-intensity isotherms in order to propose a prediction method of K …

Efficient fertilizer management was proved as a tool for increased crop production in an
environmental friendly way. Nutrient response studies determine optimum economic doses …
