The presence of straw from sugarcane (Saccharum ssp.) left on the soil surface after mechanical harvest has contributed to increase productivity of this crop and reduce potassium fertilization due to release of this nutrient ...

There is a lack of long-term research on potassium fertilization for soybean in the tropical and subtropical soils of Brazil and the residual effect of the fertilizer has generally not been considered. An experiment was ...

In order to maintain the nutrients available to plants have been studied controlled release fertilizers. In this context, the objective was to evaluate the residual effect of doses of potassium chloride, coated or not, ...

The use of potassium fertilizers on crops brings with good yields of crops and maximum profitability for farmers. Currently in Argentina, the level of production of potash fertilizers does not cover the needs of the sector ...

Potassium rates were evaluated in fig trees cv Purple of Valinhos during first development years. The experimental design was in randomized blocks with four replications and six treatments. The plots were splited in the ...

Potassium (K) leaching is affected by soil texture and available K, among other factors. In this experiment, effects of soil texture and K availability on K distribution were studied in the presence of roots, with no excess ...

Potassium contained in sugarcane straw quickly returns to the soil in a form readily available to crops. Thus, the objective of this study was to evaluate the effect of potassium on the nutritional status and grain yield ...
