The concretionary soils of Northern Ghana, which are near neutral with respect to pH and which comprise mostly lateritic ferruginous nodules are known to sorb significant amounts of phosphate. Instead of imported superphosphate, the use of less expen

Laboratory and greenhouse experiments were conducted on phosphate sorption-desorption characteristics and phosphate fertilizer requirements of concretionary soils from northern Ghana. Phosphate sorption maximum and standard P requirement were highest

Using the Langmuir isotherm, we determined the phosphate sorption of 16 important soil series developed over major parent materials in the different ecological zones of Ghana. The phosphate sorption maximum was highest (222 to 286 ppm, mean 254) in f

Sulfur availability in twenty selected surface soils (0–22 cm), which varied in both physical and chemical properties and sampled under cultivated and uncultivated management in the various ecological zones of Ghana, was studied. Texture varied fro

Studies were carried out to examine factors which might influence the distribution of S in Ghanaian soils. Nine soil profiles developed over granitic rocks, three each representing the upper slope (US), middle slope (MS) and lower slope (LS) of caten

Studies on the extractability of available Cu, Fe, Mn and Zn in soils using cation-exchange resin were carried out. A procedure involving the shaking of 5 g soil with 5 g of resin in 200 ml deionised water for 2 h at 25 ± 1°C followed by colorimetr

Visual symptoms and soil and plant analysis showed that young Amazon cocoa established on clear-felled land was K-deficient. The symptoms were more complicated than previously supposed and did not appear until the trees were four years old ; they bec

SUMMARYAn experiment is described on the establishment of cocoa on clear-felled land, using various ground covers on which 22 NP:KMg factorial treatments were later superimposed. Growth of cocoa was improved in mulched and clean-weeded plots and the
