Rates and Residual Effects of Potassium Fertilization in a Brazilian Soil

Potassium is responsible for several vital mechanisms for plant development (e. g. , enzyme activation, translocation and stock of compounds, osmotic regulation, water maintenance, etc. ) and high yields. Potassium fertilizers are essential for balanced plant nutrition in the acid soils of the tropics, including Brazil. In many areas, farmers are cutting back on fertilizer expenses, which could compromise crop yields, profits, and food security in the future.

Potassium is responsible for several vital functions for plant development (enzyme activation, translocation and stock of compounds, osmotic regulation, water maintenance etc. ) and high yields. Potassium fertilization is essential for balanced plant nutrition in the acid soils of the tropics, including in Brazil. In many areas farmers are cutting back on fertilizer expenses, which could compromise good yields, profits and food security in the future.

Potassium is, most generally, the second nutrient in terms of plant demand (after N). This nutrient is responsible for several vital mechanisms for plant development and high yields (enzyme activation, translocation and stock of compounds, osmotic regulation, water maintenance, etc). Potassium fertilizers are a must for balanced plant nutrition in the acid soils of tropics, including Brazil.

Research studying the impacts of cutting back on K fertilizer application in Brazilian soils is essential to demonstrate its medium to long-term effects. This study also intends to verify the influence of other important factors that affect K fertilizer effectiveness in tropical soils. This experiment was installed in October 2010 in Itiquira, Mato Grosso, and intends to compare 24 treatments over a 6-year time frame.
