The use of biogeochemical models to evaluate mitigation of greenhouse gas emissions from managed grasslands by Sándor, R., Ehrhardt, F., Brilli, L., Carozzi, M., Recous, S., Smith, P., Snow, V., Soussana, J.-F., Dorich, C.D., Fuchs, K., Fitton, N., Gongadze, K., Klumpp, K., Liebig, M., Martin, R., Merbold, Lutz, Newton, Paul C.D., Rees, R.M., Rolinski, Susanne, Bellocchi, G.

“…Simulated multi-model median values indicated that input reduction would lead to an increase in the C sink strength (negative net ecosystem C exchange) in intensive grazing systems: −64 ± 74 g C m−2 yr−1 (animal density reduction) and −81 ± 74 g C m−2 yr−1(N and animal density reduction), against the baseline of −30.5 ± 69.5 g C m−2 yr−1 (LSU [livestock units] ≥ 0.76 ha−1 yr−1). …”

Combining organic and mineral fertilizers for integrated soil fertility management in smallholder farming systems of Kenya : Explorations using the crop-soil model FIELD by Tittonell, Pablo A., Corbeels, Marc, Wijk, Mark T. van, Vanlauwe, Bernard, Giller, Kenneth E.

“…1 when 70% of the crop residue was left in the field, and 0.4 to 0.7 t C ha?1 yr?1 with 10% left. Degraded fields were not rehabilitated with manures of local quality (e.g., 23–35% C, 0.5–1.2% N, 0.1–0.3% P) applied at realistic rates (3.6 t dm ha?…”

Residue fractionation and decomposition: the significance of the active fraction by Vanlauwe, Bernard, Dendooven, Luc, Merckx, Roel

“…The large increase in microbial activity was accompanied by a N-immobilization of 65 and 29 mg N Kg-1 dry soil for the maize-straw treatment and its insoluble fraction, respectively, resulting in biomass C/N values of 5.5 and 5.6 A genuine priming effect (10 and 7% of the total CO2-C production) on the mineralization of native soil organic C was caused by an increase in decomposition of the native C rather than by an increase in turnover of the microbial biomass in the soil amended with maize straw. …”

Aspectos de la biología y el consumo de Neoseiulus cucumeris y Typhlodromalus aripo (Acari: Phytoseiidae) con la presa Thrips palmi (Thysanoptera: Thripidae) by Cuéllar Jimenez, M.E., Bellotti, Anthony C., Melo Molina, E.L.

“…The studies were carried out under laboratory conditions (25 ± 5°C, 75 ± 5% of r. h. and 12:12 L:D). The development period of N. cucumeris when feeding on T. palmi and T. urticae was 8.9 and 8.5 days respectively. …”

Soybean (Glycine max) response to rhizobia inoculation as influenced by soil nitrogen levels by Nyaguthii, M.C.

“…A second greenhouse experiment with two soils selected based on the first experiment was used (with 0.06 % N and 0.08 % N). A complete randomized design was used with three replicates and five rates of an organic N source (i.e. 0, 2.5, 5, 7.5 and 10 t Phymyx ha-1) for each soil N level, with and without inoculation to assess whether the organic amendment could improve the response to inoculation within the adequate range of N. …”

Long-term mineral fertiliser use and maize residue incorporation do not compensate for carbon and nutrient losses from a Ferralsol under continuous maize-cotton cropping by Kintché, K., Guibert, H., Sogbedji, J.M., Levêque, J., Bonfoh, Bassirou, Tittonell, Pablo A.

“…Although C inputs to soil under RR and 1.5 RR were greater than in the No-Fertiliser control (nil for Tillage-NoCrop), and the N input was more favourable for 1.5RR, the rates in which contents of soil C and N decreased over time did not differ substantially between treatments. …”
