Research results on the use of OM to maintain soil fertility, with particular reference to bean crops in Africa, are reviewed. Aspects covered are (1) the role that soil OM plays in soil physical structure, chemical properties, and biological activities and (2) the different interactions of manag...

Researchers worked with farmers in eastern Uganda to develop alternatives for soil management using crotalaria (Crotalaria ochroleuca), mucuna (Mucuna pruriens var. utilis), lablab (Dolichos lablab), and canavalia (Canavalia ensiformis) as green manures in short-term fallows. The participatory re...

Green manures for maize-bean systems in eastern Uganda: Agronomic performance and farmers' perceptions
The potential of Crotalaria ochroleuca check for this species in other resources as a green manure crop was evaluated in a series of on-station and on-farm trials on reddish kaolinitic loam and sandy clay loam soils in Uganda. Production of the green manure by intercropping Crotalaria with eithe...

Crotalaria ochroleuca as a green manure crop in Uganda
The decomposition and nutrient release of 12 plant materials were assessed in a 20-week litterbag field study in hillsides from Cauca, Colombia. Leaves of Tithonia diversifolia (TTH) and Indigofera constricta (IND) decomposed quickly (k=0.035±0.002 d?1), while those of Cratylia argentea (CRA) and...

Tithonia diversifolia (Mexican sunflower) is a shrub commonly used as a green manure crop in Central and South America, Asia and Africa as it accumulates high levels of phosphorus and other nutrients, even in depleted soils. In root samples collected from the global distribution of Tithonia, we e...
