Global climate change is the major cause of abiotic and biotic stresses that have adverse
effects on agricultural productivity to an irreversible level, thus threatening to limit gains in …

Among the plant nutrients, potassium (K) plays a fundamental role in plant physiology and
the soil-plant dynamics of various nutrients. Careful rate recommendations for K are needed …

Soybean production in sandy soils under the recovery process presents risks that can be
mitigated by growing crops between crop seasons, focused on silage production, which can …

Potassium (K) is the primary limiting nutrient for cassava, being essential to achieve
sustainably satisfactory cassava yields in low K reserve sandy soils that require proper K …

Biochar (BC) and cattle manure (CM) are carbon-nutrient-rich organic substances and have
long been used to improve crop yield and soil fertility. Nevertheless, their combined effect …

In humid tropical regions, intense weathering extensively depletes soil nutrients. However,
soils in the Araguaia River Valley, Brazil, are not responsive to potassium (K) fertilization. To …

Cover crops can be used to accelerate the solubilization process of low-solubility fertilizers;
thus, the aim of this study was to evaluate the potential of grasses in solubilizing potassium …

In soil, potassium (K) is present as structural K, non-exchangeable K (Kne) and
exchangeable K (Ke). Exchangeable K is considered available to plants, but exudates from …

Integrated use of inorganic fertilizer and organic manure restores soil quality and increases
crop productivity. Potassium (K) pools are also affected in soil due to the rate and sources of …

Context The NaHCO3-extractable soil K test (Colwell K) is the most frequently used method
for soil K across Australia, but there is still uncertainty about the suitability of K testing …
