Decreased potassium fertilization in sugarcane ratoons grown under straw in different soils
(2015-01-01)
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 ...
Residual and annual potassic fertilization for soybeans
(Kluwer Academic Publ, 2001-01-01)
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 ...
Cloreto de potássio revestido em efeito residual no feijoeiro de inverno irrigado na região de cerrado
(2013-05-01)
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, ...

Alternatives for the production of Potassium Fertilizers in Argentina
(Longdom, 2019-12)
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 ...
Fig trees (Ficus carica L.) leaf nutrients contents with potassium fertilization
(Univ Federal Lavras-ufla, 2005-05-01)
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 Leaching as Affected by Soil Texture and Residual Fertilization in Tropical Soils
(Taylor & Francis Inc, 2010-01-01)
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 ...
Effect of potassium on nutritional status and productivity of peanuts in succession with sugarcane
(Soc Chilena Ciencia Suelo, 2015-01-01)
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 ...
