Soils from humid tropics are generally acidic, and liming is required in order to raise pH and base saturation, and reduce exchangebale (Al3). Phosphorus (P) is strongly associated with the mineral phase of highly weathered tropical soils, and its plant availability increases with increasing pH. In soils under consolidated no-till (NT), the broadcasted lime occurs without incorporation. I…
Potassium (K) acts over the enzymatic and metabolic processes at the cellular environment, and its availability to plants depends on its forms and on its behavior in the soil. The extraction of available contents of K is established as a reference for diagnosis and fertilization calculations in Brazil. However, the absence of response of crops to potassium fertilizer has been verified in …
Phosphorus (P) is present in soil solution as oxyanions. The mineral phase of humid tropical soils generally present high Al- and Fe-(hydr)oxides contents that adsorb high amounts of P. These soils are generally acidic, and liming is necessary to increase calcium (Ca) and magnesium (Mg) contents, to decrease aluminum (Al) contents as a result of increasing pH. Liming also promotes the inc…
