The effect of land use on the availability of soil nitrogen (N) was studied by separating total soil N into one labile and one stable fraction by oxidation and extraction of labile N with potassium permanganate. The nitrogen management index (NMI) was calculated according to Blair et al. (1995)…

The study establishes the link between agricultural labor productivity and natural resources variables at the national level in Honduras. We show through spatial analysis of productivity and natural resources that the relationship between natural resource conditions and agricultural productivity…

The effects of land-use change on the structure of Oxisols in the Brazilian savannas (also known as the Cerrados) are still insufficiently understood. We therefore studied loamy and clayey Oxisols under natural savanna, crop, pasture, and reforestation to (1) quantify management-induced changes…

This article presents criteria and recommendations to support the landuse planning process in the savanna land ecosystem of the municipality of Puerto Lopez. These criteria were established from the analysis and correlation of the characteristics of the landscape and soils, taking in…

Land tenure issues are becoming increasingly important worldwide. Problems such as high population pressure, increases in resource degradation, food shortages, transformations of political systems and regional and supra-regional resource conflicts have brought the land issue to the public's…
