Descripción
Potassium (K) fertilization is one of the most common nutrient inputs used by farmers to cultivate crops on Brazil?s highly weathered, low-fertile and acidic tropical soils. Soil K is typically classified in four forms: structural (in some primary minerals), non-exchangeable (specific adsorption), exchangeable and solution.
