| Highly weathered tropical soils are characterized by having a predominantly variable charge. Many management practices commonly used in the exploitation of these soils (e.g.,liming, phosphate application, and manuring) are known to modify their electrical charge and the sorption/desorption behavior of cations and anions. This process is, at least, partially governed by the charges existing in the soil system. Available information on this subject comes mainly from short-term laboratory and greenhouse experiments. There is a lack of data regarding the cumulative and long-term effects of those practices used at farm-scale levels and on the dynamics and availability of nutrients to the plants under field conditions. In the present work, changes in some... |
