Changes in Soil Physical Properties and Carbon Protection Mechanisms by Surface Application of Lime in a Tropical No-Tillage System
(Soil Sci Soc Amer, 2018-01-01)
Long-term no-till soils often have layers that are severely affected by physical and chemical degradation. Soil acidity is associated with physical problems, such as higher bulk density, that restrict root growth and crop ...
Impact of amendments on the physical properties of soil under tropical long-term no till conditions
(2016-12-01)
Tropical regions have been considered the world's primary agricultural frontier; however, some physico-chemical deficiencies, such as low soil organic matter content, poor soil structure, high erodibility, soil acidity, ...
