Phosphate sorption by andisols and ultisols, and its implication on phosphorus bioavailability in the wet tropics of Tanzania
Abstract

Phosphorus (P) sorption and desorption behaviour of Andisols
of Siha - Kilimajaro and Ultisols of Magadu -Morogoro, Tanzania
was studied in pot experiments. This was to facilitate
development of P management strategies for enhanced maize
productivity as these areas have high P sorption capacities and
require high amounts of this nutrient for it to be available to
crops. Six P rates (0, 0.1, 0.2, 0.4, 0.8, and 1.0 mg P L-1) were
studied. There was a significant increase in maize dry matter
yield with addition of P at all rates. It is therefore recommended
that soils in the study areas be supplemented with P to improve
its availability to maize and thereby increase crop yield.
