Long-Term Integrated Soil Fertility Management in South-Western Nigeria: Crop Performance and Impact on the Soil Fertility Status

The State of Soil Degradation in Sub-Saharan Africa: Baselines, Trajectories, and Solutions

“…Extensive research has been conducted into the broader frameworks of integrated soil fertility management [130][131][132][133][134][135][136][137], conservation agriculture [138][139][140][141][142][143], erosion control [144][145][146][147][148], and improved grazing management [149][150][151]. There is also a wealth of information on the benefits of specific practices such as short legume rotations (improved fallows) [152][153][154][155][156][157][158], agroforestry systems [159][160][161][162][163][164][165], and no-till systems [166][167][168][169][170].…”

Productivity of Maize (<i>Zea mays</i> L.) and Mung bean (<i>Vigna radiate</i> L. Wikzek) in Homegardens and Cropping Fields under Subsistence Conditions

“…Green Manure (GM) was used primarily as a soil amendment and a nutrient source for subsequent crops and could provide an alternative source of fertilizers. Many studies on the impact of trees on field crop productivity of smallholder units have been carried out in Africa, with special emphasis on alley cropping (Vanlauwe et al, 2005). In South Asia, such studies are seldomly reported although over 30% of the world's population live in this region.…”

Impact of Green Manure on Productivity Patterns of Homegardens and Fields in a Tropical Dry Climate

“…Higher yields without adequate inputs may have created this depletion of SOM which strengthens the significant correlations between grain yield and SOM content in Homegardens. This is a general phenomenon in tropical farming systems (Vanlauwe et al, 2005). The less productive lands in the Steep category did not show the same rate of SOM stock depletion in both Homegardens and Fields.…”

“…The less productive lands in the Steep category did not show the same rate of SOM stock depletion in both Homegardens and Fields. Although many studies suggest a persistent influence of green manures (Vanlauwe et al, 2005) in alley cropping or hedgerows systems, which was more similar to the Homegarden conditions in the Meegahakiula region, this effect seems to be quite variable and subject to cultivation measures adopted by the farmer.…”
