Tropical Africa escaped from the glaciers that covered the temperate parts of the world during the Ice Age. The legacy is that most of the parent materials of the soils of tropical Africa are old, highly weathered and devoid of bases and phosphate-be

Africa enters the twenty-first century as the continent with the most daunting development challenges. The inability to feed its population, projected to reach one billion by 2025, is one of these challenges. Data for 1995 from the World Bank reveal

Less than 10 percent of the Mg added to soils at the rates of 0.5, 1.0, 5.0, and 10.0 symmetry concentrations was retained in forms not extractable with neutral N NH4OAc. There was no evidence of Mg fixation by either the clay or organic fractions of

A second order equation best described the relationship between exchangeable Mg and both total and acid‐soluble Mg in select temperate and tropical soils. The relationship between acid‐soluble and total Mg was linear. Soil types differ in their M

An increase in pH of soils from the savannah zones of Nigeria to which varying quantities of phosphate were added increased the phosphate adsorbed by the soils. It is suggested that high pH increased the activity of hydroxy-aluminum. Phosphate was ad

A scheme was developed for fractionating soil Mg into exchangeable, organic-complexed, acid-soluble, and primary mineral forms. The scheme was tried out on 20 soils from different regions of the world. Magnesium content was influenced by the nature o
