Soil PH An Indices For Effective Management Of Soils For Crop Production.

Abstract - The PH properties of the soils of the Peter Natter School of Agriculture Ugwuomu Enugu state were investigated. Soil samples were collected from surface and subsurface horizons 0-20cm and 20-40cm respectively in seven different locations. The two different horizon depths are tagged x and y and soil samples of the same depth in the seven different locations were bulked together as composite samples for soil PH. The PH levels of the soils were analyzed and the characteristics of the soils described. The soils of the study area were predominantly acidic and PH range was 4.9-6.0. The soils of the two horizons depth were also acidic in nature both in H2O and KCl and the charge particles range from 1-3 positive. Generally the results of the soils were below the level adaptable to most of the arable and field crop production as well as nutrient uptake and availability and Microbial activities.
