Biological factors of fertility were assessed through the study of litter quantity and quality, soil organic matter quantity and quality, soil microfauna, soil macrofauna, organic matter dynamic, particularly decomposition and non-symbiotic nitrogen fixation in an age series of Eucalyptus PF1 and...

Changes in biological factors of fertility in managed Eucalyptus plantations on a savanna soil in Congo
In the southern coastal region of Congo near Pointe-Noire, savanna covers large areas on very poor sandy soils. These savannas have been used since 1978 for plantations of fast growing trees, mainly eucalypts, which are grown commercially. A particular feature of the Congolese plantations was the...

Eco efficiency of Integrated Soil Fertility Management in Western Kenya
Increased rice production in East and Southern Africa explains the crucial role rice plays in household food and income security. However, in last three decades, rice productivity per unit area has stagnated due to abiotic and biotic factors, hence the need for the application of Integrated Soil ...

Exploring options for lowland rice intensification under rainfed and irrigated ecologies in East and Southern Africa: the potential application of Integrated Soil Fertility Management principles
This paper explores the claim whether agro-forestry is a second soil fertility paradigm. The answer to this question, however, is not unequivocal. Farmers in Western Kenya generally do not apply fertiliser and rather rely on many soil fertility replenishment (SFR) strategies. Scientists recognise...

Near-infrared (NIR) diffuse reflectance spectroscopy for the prediction of carbon and nitrogen in an Oxisol = Espectroscopia de reflectancia difusa por infrarrojo cercano (NIR) para la predicción de carbono y nitrógeno de un Oxisol
Intensification of agricultural systems in sub-Saharan Africa (SSA) is considered a pre-condition for alleviation of rural poverty. Conservation Agriculture (CA) has been promoted to achieve this goal, based on three principles: minimum tillage, soil surface cover, and diversified crop rotations....
