Nitrogen mineralization dynamics in response to organic residue and synthetic fertilizer inputs
Abstract Modern maize (Zea mays L.) production relies on intensive fertilization with synthetic N and generates massive amounts of residue C. The short‐term effect of these inputs on N mineralization in two soils of contrasting N supply was studied by continuously monitoring CO2 production during a 60‐day laboratory incubation experiment that also ...

Nitrogen mineralization indicators in the southwest of the argentinean pampas: relationship with soil organic fractions [PDF]
En la actualidad, no existen estudios que establezcan las relaciones de los indicadores rápidos de mineralización de nitrógeno (N)-como el N incubado en anaerobiosis (Nan) y el N hidrolizable (Nhid)-con las fracciones orgánicas en suelos con aportes ...

Nutrient Cycling Index in Relation to Organic Matter and Soil Respiration of Rehabilitated Mine Sites in Kelian, East Kalimantan [PDF]
Degraded soils at mine sites are often associated with decreased soil fertility. However, soil nutrient status might be improved through biomass recovery primarily from re-vegetation. This paper relates nutrient cycling index (NCI) derived from Landscape

Relationships among main soil properties and three N availability indices. [PDF]
A biological (aerobic incubation for 3 and 6 weeks) and a chemical method [successive extractions with cold 0.1 (H1-N) and 0.5 M HCl (H2-N)] were applied to 21 soils to determine: a) the potentially mineralizable-N; b) the most useful soil variables ...

Modification of DRAINAGE Model by Using the Nitrogen Component from the GLEAMS Model [PDF]
The NITRO subroutine of the DRAINAGE model (Kanwar et al., 1983) was modified using the nitrogen transformation components of the GLEAMS (Leonard et al., 1987) model to predict more accurately the leaching of NO3-N to subsurface drainage water. Predicted
