Influence of Poultry Manure and NPK Fertilizer on Hydraulic Properties of a Sandy Soil in Ghana

Field experiment was conducted during the 2008 major rainy season at the experimental field of the Department of Horticulture, Faculty of Agriculture, KNUST to test the effects of poultry manure (PM) and NPK fertilizer on the hydrological properties of a sandy soil. There were five treatments with five replications. The experiment was laid in Randomized Complete Block Design. Data were collected on the following soil properties: cumulative infiltration amount (I), sorptivity (S), steady state infiltrability (Ko) and saturated hydraulic conductivity (Ks). At the end of the experiment the control plot recorded the highest values of I, S, and Ko as 257 mm, 3.90 mm/s 1/2 and 0.07 mm/s, respectively. However the highest Ks was recorded as 1.72×10 -4 on the sole NPK-incorporated plot which showed no significant difference from that recorded on the control plot (1.69×10
