| dc.description | A study conducted on the soils of the brackishwater experimental fish farm Buguma, showed that the area contains potential acid-sulfate materials within 12cm of pond bottom in the soil profile. The sulfate sulfur (SO4-S) content of the sulfidic horizon is 2,700ppm. High values of exchangeable acidity and Al were also recorded for this horizon. Values were 16.96 and 7.89 meq/100g of soil respectively. The soils are saline, characterised by high soluble salt content and high values of K, Ca and Mg ions. pH values in the wet state ranged between 7.7 and 6.9, but on air drying, values went down to as low as 3.1. Total nitrogen and available phosphorus were relatively low, values ranged from 0.07 – 0.35% and 1.40 – 7.08 ppm respectively. Lime requirement was calculated for the soils; results indicate the need for approx. 4.1 tonnes of agricultural lime per hectare for neutralization | |
