Calagem superficial em pastagem e correção de solo em profundidade

Abstract

The Brazilian soil is naturally acidic, so there is a need for acidity correction methods, as different forms of application of limestone in the incorporated or superficial soil bring distinct advantages, according to the use of the soil, superficial limestone application is recommended for correction either in no-tillage system or in perennial crops such as pastures. The superficial application of lime provides a lower cost of machinery and tends to keep the physical structure of the soil unchanged. This work aimed to study the effects of the application of superficial lime and its efficiency at a depth of 0-20cm, the depth at which the roots of the most of the grasses used in pastures with access.
