Carbono orgánico del suelo bajo sistemas de cultivo contrastantes y su relación con la capacidad de proveer nitrógeno por Studdert, Guillermo, Domingo, Magalí Noé, Garcia, Gisela Vanesa, Monterubbianesi, María Gloria, Dominguez, Germán Franco

“…Los contenidos de carbono (C) orgánico total (COT) y particulado (COP) del suelo disminuyen con los años bajo agricultura y su variación afecta muchos procesos edáficos que determinan la productividad (e.g. la provisión de nitrógeno (N)). …”

The utility of process-based models for simulating N2O emissions from soils: A case study based on Costa Rican coffee plantations por Hergoualc'h, Kristell, Harmand, J.M., Cannavo, P., Skiba, U., Oliver, R., Henault, C.

“…Soil moisture dynamics were satisfactorily simulated by PASTIS. Simulated N2O fluxes by both NGAS and NOE (3.2 and 2.1 kg N ha(-1) y(-1) for NGAS; 7.1 and 3.7 kg N ha(-1) y(-1) for NOE, for the monoculture and shaded plantations respectively) were within a factor of about 2 of the observed annual fluxes (4.3 and 5.8 kg N ha(-1) y(-1), for the monoculture and shaded plantations respectively). …”

Fertility management for maize cultivation in some soils of Western Kenya por Ajebesone, F.N., Mathias, B., Kelvin, M.M., Mussgnug, F.

“…Irrespective of the season, organic amendments were more effective than mineral fertilizers in enhancing soil carbon stocks and the labile and non-labile C fractions. The largest soil C content (4.1%) and C pool (72Mgha⁻¹) were observed on the clay Nitisol after two seasons of reduced tillage, while the lowest C content (1.1%) and C pool (22Mgha⁻¹) were observed on the sandy Acrisol with conventional tillage. …”

Towards a baseline for reducing the carbon budget in sugarcane: three years of carbon dioxide and methane emissions quantification por Chalco Vera, Jorge Elias, Acreche, Martin Moises

“…There was not a clear pattern in the dynamics of CH4 flux for all sugarcane treatments, while the native forest consistently captured CH4; however, the cumulative CH4 flows were negligible in term of C mass. Annual cumulative CO2 emissions were 12.4–61.4 and 5.9–51.5% higher (for N-fertilized and unfertilized treatments, respectively) when straw was not burned regarding to the burned treatment. …”
