Eight chemical methods were employed for estimating the available P in 32 Ethiopian soils using Phasey bean (Macroptilium lathyroides c.Murray) as a test crop grown in small pots in a glasshouse and the soil test values then correlated with plant characteristics. Olsens' method gave the highest c...

Sesbania, particularly S. sesban species, grow naturally in many parts of Africa where they form natural browse. Productivity of Sesbania as animal feed is widely limited by soil acidity and low In this study, eighteen ILCA accessions of S. sesban and two of S. goetzei, all but two from Africa, w...

Examines the present status of research on copper (Cu) in the soil, plant and ruminant animal system in sub-Saharan Africa with emphasis on forage crops. The soil content of total and available Cu and the distribution of Cu in the soil profile are demonstrated. The biochemical role of Cu in the p...
