Millet nutrient use efficiency as affected by natural soil fertility, mineral fertilzer use and rainfall in the West African Sahel por Fofana, B., Wopereis, Marco C.S., Bationo, B. André, Breman, H., Mando, A.

“…While soil organic carbon (1.5 g kg?1 on outfields and 1.6 g kg?1 on infields) and pH-H2O (4.8 on outfields and 5.1 on infields) were comparable, total-N, plant available P (measured as P-Olsen and P-Bray), and exchangeable Ca, K, and Mg levels were higher on infields as compared to outfields. …”

Optimizing soil fertility gradients in the Enset (Ensete ventricosum) systems of the Ethiopian highlands: Trade-offs and local innovations por Amede, Tilahun, Taboge, E.

“…The recent shift from enset to cereals and continual soil fertility decline in the outfields caused food deficit for at least 3 months in a year. …”

Multiple benefits of manure : The key to maintenance of soil fertility and restoration of depleted sandy soils on African smallholder farms por Zingore, Shamie, Delve, Robert J., Nyamangara, Justice, Giller, Kenneth E.

“…Significant maize responses to application of N and manure were observed on all fields except the depleted sandy outfield. Large amounts of manure (17 t ha?1 year?1) were required to significantly increase soil organic carbon (SOC), pH, available P, and base saturation, and restore productivity of the depleted sandy outfield. …”

Altitude and management affect soil fertility, leaf nutrient status and Xanthomonas wilt prevalence in enset gardens por Shara, Sabura, Swennen, Rony L., Deckers, Jozef, Weldesenbet, Fantahun, Vercammen, Laura, Eshetu, Fassil, Woldeyes, Feleke, Blomme, Guy, Merckx, Roel, Vancampenhout, Karen

“…Hence, over-fertilization is likely, and establishing evidencebased nutrient recommendations for enset would benefit soil quality and productivity both in the gardens and in the outfields. Disease prevalence was high in the study area, with one-third of the farms affected in the recent past. …”

Effects of nitrogen fertilizer and manure application on storage of carbon and nitrogen under continuous maize cropping in Arenosols and Luvisols of Zimbabwe por Mujuru, Lizzie, Rusinamhodzi, Leonard, Hoosbeek, M.R., Nyamangara, Justice

“…Estimation of equilibrium levels suggested that homefields had potential to store more C, whereas outfields and control treatments had limited capacity due to attainment of lower equilibrium levels. …”

Resource use and food self-sufficiency at farm scale within two agro-ecological zones of Rwanda por Bucagu, C., Vanlauwe, Bernard, Wijk, Mark T. van, Giller, Kenneth E.

“…The partial N balance was more negative in Kageyo (−35.87 kg N ha−1 year−1) while the P balance was negative in close fields and outfields but positive in homefields (0.43 kg P ha−1 year−1). …”

Determinants of survival and growth of tree lucerne (Chamaecytisus palmensis) in the crop-livestock farming systems of the Ethiopian highlands por Mekonnen, Kindu, Jogo, W., Bezabih, Melkamu, Mulema, Annet A., Thorne, Peter J.

“…The results of the study show that percentage survival on-farm were significantly higher for tree lucerne planted in backyards than those planted in outfields and for middle-resource class households. …”

Drivers of soil organic carbon stocks at village scale in a sub-humid region of Zimbabwe por Nyawasha, R.W., Falconnier, G.N., Todoroff, P., Wadoux, A.M., Chikowo, R., Conquerean, A., Leroux, L., Jahel, C., Corbeels, M., Cardinael, R.

“…This study was conducted in a smallholder communal area of Zimbabwe with the following objectives: i) to quantify SOC stocks under contrasting land uses and soil types, and estimate landscape-level SOC stocks, ii) to assess the impact of historical agricultural management parctices on SOC in croplands (homefields vs outfields), and iii) to estimate temporal changes in SOC stocks due to land use change using field measurements and geospatial data (Africa Soil Information Service, AfSIS). …”
