Abstract

In the Amazon landscape, areas with black lands archaeological (TPA's) are increasingly fragmented due to deforestation and agricultural use, which causes changes mainly in soil physical properties. Thus, the research aims to study the changes in the physical and mechanical behavior of the soil in archaeological black earth in areas cultivated with TPA's natural and corn and TPA's natural and pasture. Mapping areas of black lands archaeological with the following uses will be held: a) TPA's natural and corn b) TPA's natural and pasture. In each area, meshes shall be established sample with the dimensions 80 x 56 m, with intervals between points of 8.0 m, totaling 88 sampling points. Sampling of physical attributes and soil mechanics and root crops will be carried out in layers of 0.00-0.05, 0.05-0.10, 0.10-0.20 and 0.20-0.40 m at the crossover points of the meshes with 352 soil samples per area. Soil physical quality will be evaluated by limiting water range and specific soil functions. The soil structure is evaluated through analysis by micro and soil load bearing capacity of the soil correlating the preconsolidation pressure and gravimetric moisture. After analysis of the data will be conducted analyzes of descriptive statistics and geostatistics. Thus, understanding the physical processes involved in the degradation of TPA's allows you to search by less impacting cropping systems for their features. The use of corn crops and pasture in archaeological black earth determines which culture will provide better conditions for soil structure, load-bearing capacity and optical water range to maintain soil conservation when compared to natural TPA.
