Soil Organic Matter Quality From Soils Cropped by Traditional Peasants

In this work we have analyzed soil samples from Oxisols collected from two traditional communities, one formed by Guarany Indians at South of Brazil and other by African descendants on North of Rio de Janeiro State, Brazil. The content and fractional composition of humus was investigated and the isolated humic acids (HAs) were characterized by elemental composition, C solid-state nuclear magnet...

Modeling Soil Depth from Topographic and Land Cover Attributes

[1] Soil depth is an important input parameter in hydrological and ecological modeling. Presently, the soil depth data available in national soil databases (STATSGO and SSURGO) from the Natural Resources Conservation Service are provided as averages within generalized land units (map units). Spatial uncertainty within these units limits their applicability for distributed modeling in complex te...

Transgenes sustain epigeal insect biodiversity in diversified vegetable farm systems.

Many ecological studies have focused on the effects of transgenes in field crops, but few have considered multiple transgenes in diversified vegetable systems. We compared the epigeal, or soil surface-dwelling, communities of Coleoptera and Formicidae between transgenic and isoline vegetable systems consisting of sweet corn, potato, and acorn squash, with transgenic cultivars expressing Cry1(A)...

Field Heterogeneity of Soil Organic Carbon and Relationships to Soil Properties and Terrain Attributes

Our objectives were to: (1) characterize SOC (0 to 1.53-m) within a 37-ha field typical of the Palouse region in eastern Washington; and (2) assess correlations and how much SOC variance could be accounted for by terrain and soil variables. A systematic, non-aligned grid of 177 georeferenced sample locations was established at the Washington State University Cook Agronomy Farm (CAF) near Pullma...
