Spatial variability of physical, chemical and biological properties of agricultural soils in Hidalgo State, Mexico Agricultural soil properties

Abstract

The spatial distribution of physical, chemical and biological soil, affecting crop yields, however, the spatial dependence of soil biological parameters has been little explored. A study was conducted to establish the influence on soil fertility showed spatial variations of physical, chemical and biological properties of two agricultural soils in Hidalgo State (Mexico), belonging to the order Cambisol with low clay content activity. Soils A, (with a phase-clay-sandy, shallow horizon imperfect drainage), the municipality of Apan and soil B (with a light phase and thick, with stones), the municipality of Emiliano Zapata, were sampled in a network of 10x10m at 10, 20 and 40 cm deep. Were determined by physical, chemical and biological both soils. Geostatistical analyzes were performed using SPSS version 17.0. Texture, soil moisture and organic compounds changes affect the spatial distribution of the physical, chemical and biological properties of soils tested. The spatial variability of organic carbon, total nitrogen and C/N increased significantly with depth in the two soils, while the bulk density showed little spatial variation.
