Effect Of Organic Amendment On Some Physico-Chemical Properties Of Soil In Bende Local Government Area Of Abia State, Nigeria

ABSTRACT

The experiment was conducted at Michael Okpara University of Agriculture, Umudike in the soil science laboratory to determine the effect of organic amendment on some physico-chemical properties of soils in Bende Local Government Area of Abia State, Nigeria. The amendment were Aspilia Africana, poultry manure and combination of both poultry manure and Aspilla africana, applied at the rate of Og,5g,lOg and 15g respectively and replicated three times. Soil samples were collected from 0-15, 15-30, 30-45 cm depth, air dried and sieved through a 2mm sieve. The physico-chemical properties analyzed include organic carbon, total nitrogen, soil PH, available phosphorus, exchangeable bases, exchangeable acidity, ECEC and % base saturation. Data collected was subjected using the mean values. Result indicate that organic amendment used during the analysis improved organic carbon, organic matter, total nitrogen, of the amended soil. Similar trends were observed for soil pH, ECEC, and % base saturation while available phosphorus decreased relative with the application of the amendment.
