Effect of lime and goat manure on soil acidity and maize (Zea mays) growth parameters at Kavutiri, Embu County- Central Kenya

A greenhouse pot experiment was conducted to determine the effect of agricultural lime and goat manureon soil acidity and maize growth parameters using soils from Kavutiri-Embu County. Nitrogen and phosphorus fertilizers at the rates of 50 and 70 kg ha-1, respectively, and goat manure at three rates (0, 5 and 10 mg ha-1) and agricultural lime (CaCO3) at six rates (0, 2.5, 5, 7.5, 10, and 12.5 mg ha-1) were used for the...
