Nitrogen balances in farmers fields under alternative uses of a cover crop legume: a case study from Nicaragua

Autor: Douxchamps, Sabine Humbert, FL Hoek, Rein van der Mena Urbina, Martin A. Bernasconi, S Schmidt, A Rao, Idupulapati M. Frossard, Emmanuel Oberson, Astrid

Canavalia brasiliensis (canavalia), a drought tolerant legume, was introduced into the smallholder traditional crop-livestock production system of the Nicaraguan hillsides as green manure to improve soil fertility or as forage during the dry season for improving milk production. Since nitrogen (N...

Nitrogen fertilizer equivalencies of organics of differing quality and optimum combination with organic nitrogen source in Central Kenya

Autor: Kimetu, J.M. Mugendi, DN Palm, C.A. Mutuo, PK Gachengo, CN Bationo, B. André

Decline in crop yields is a major problem facing smallholder farmers in Kenya and the entire Sub-Saharan region. This is attributed mainly to the mining of major nutrients due to continuous cropping without addition of adequate external nutrients. In most cases inorganic fertilizers are expensive...

Nitrogen mineralization and crop uptake from surface-applied leaves of green manure species on a tropical volcanic-ash soil

Autor: Cobo Borrero, Juan G. Barrios, E. Kass, DCL Thomas, Richard J.

Leaves of nine green manure (GM) species were surface applied to a tropical volcanic-ash soil at a rate of 100 kg N ha 1 in order to evaluate their N-fertilizer value in a glasshouse experiment. GM treatments were compared to urea at two rates, 50 kg N ha 1 (FN50) and 100 kg N ha 1 (FN100), and t...

Development and field performance of nitrogen use efficient rice lines for Africa

Autor: Selvaraj, Michael Gomez Valencia, Milton Orlando Ogawa, Satoshi Lu, Yingzhi Wu, Liying Downs, Christopher Skinner, Wayne Lu, Zhongjin Kridl, Jean C. Ishitani, Manabu Boxtel, Jos van

Nitrogen (N) fertilizers are a major input cost in rice production, and its excess application leads to major environmental pollution. Development of rice varieties with improved nitrogen use efficiency (NUE) is essential for sustainable agriculture. Here, we report the results of field evaluatio...

Effects of Alternate Wetting and Drying Irrigation Regime and Nitrogen Fertilizer on Yield and Nitrogen Use Efficiency of Irrigated Rice in the Sahel

Autor: Djaman, K. Mel, V.C. Diop, L. Sow, A. El-Namaky, R. Manneh, B. Saito, K. Futakuchi, K. Irmak, S.

The objectives of this study were to investigate water saving strategies in the paddy field and to evaluate the performance of some of the newly released rice varieties. Field experiments were conducted at Fanaye in the Senegal River Valley during two rice growing seasons in 2015. Three irrigatio...

Effect of biochar derived from faecal matter on yield and nutrient content of lettuce (Lactuca sativa) in two contrasting soils

Autor: Woldetsadik, D. Drechsel, Pay Marschner, B. Itanna, F. Gebrekidan, H.

Background: Faecal matter biochar offers an interesting value proposition where the pyrolysis process guaranties a 100% pathogen elimination, as well as significant reduction in transport and storage weight and volume. Therefore, to evaluate the effect of (1) biochar produced from dried faecal ma...

The Food-Energy Nexus is Closer to our Heart than we might think

Autor: Drechsel, Pay

Reflecting on the food-energy nexus, my first thought went to the Haber–Bosch process. Perhaps no other human invention has had a more dramatic impact on our wellbeing and mother Earth than the Haber-Bosch chemistry. As the reader might know, and I am citing here largely from Wikipedia, the Haber...
