Abstract: | A survey was conducted in the Upper East region of Ghana to seek information on the fertility
status of the soils, manure production, its management options and nutrient concentration that
could be associated with quality. Analysis of soils from farmers’ fields showed that the soils are
coarse textured, with low exchange capacity and organic matter contents. Available P in particular
was very low with most of the soils having values less than 6.00 ppm. Four main types of cattle
rearing systems were encountered; the field, kraal, compound and intensive. Fresh manure
samples from each of these systems were collected air dried and analysed in the laboratory using
standard protocols. The N and P contents of the manure ranged from 0.52 % to 1.14 %, and 0.28
% to 0.76 % respectively, which were below the critical levels for net mineralization. Polyphenol
contents on the other hand were lower than the critical value of 4 %. Decomposition and nutrient
release of the manure showed immobilization of total N during the first four weeks, suggesting
the need to improve the quality by composting or applying it in combination with mineral
fertilizers. |
