ABSTRACT One of the pillars a no-tillage system is addition adequate amounts residue to keep soil continuously covered. Cover crops are tool for supplying demand permanence residues on surface and releasing nutrients soil. However, there no index that relates these two factors can reconcile maximum crop in with N supply via mineralization such residues. This study aimed assess effect different ...

Abstract. E or pyriminobac-methyl (EPM), a pyrimidine benzoic acid esters herbicide, has high potential as weedicide; nevertheless, its environmental behaviors are still not well understood. In this study, we systematically investigated, for the first time, adsorption–desorption, degradation, and leaching of EPM in agricultural soils from five exemplar sites China (Phaeozems – S1; Anthrosol S2;...

Context Ferralsols, which cover approximately 6% of the Earth’s continental surface, have unique phosphorus (P) retention properties. Aims The research investigates P adsorption properties under non-controlled conditions on lateritic soil samples, combining different methodological approaches. Methods Ferralsol samples were analysed using (1) kinetics and capacities (wet chemical experiment met...

The evaluation of soil susceptibility to runoff and water erosion in the field is often expensive or time-consuming. Several authors have reported that susceptibility is linked to aggregate stability, whose determination is far easier. However, this susceptibility has generally been deduced from rainfall simulation experiments on sieved soil samples, whose behaviour is not always representative...

Ž . Not only the amount of organic carbon in soil is important for soil organic matter SOM stability, but also its physical and chemical properties. The appropriate technique for the assessment of SOM dynamics can vary between soil types, and information about this is lacking for Ferralsols of the central Amazon basin. First, this work identified SOM pools which are sensitive to land-use change...
