Conteúdo: | Sustainable crop production on Rwandan oxisols is limited by widespread soil acidity caused by high levels of exchangeable aluminium. This study was designed to test the effectiveness of an indigenous lime material in counterating the acidity and enhancing crop yields. Lime application signifcant  raised pH, exchangeable calcium and effective cation exchange capacity, and reduced exchangeable  aluminium and total acidity . Calcium was directly proportional to effective cation exchange capacity (r=0,962) and was inversely related to aluminium (r=0.955)...
