Response of Sorghum (Sorghum bicolor (L.) Munch) and Chemical Characteristics of Soil to Organic and Inorganic Fertilizers on Kenyan Lower Midlands Acid Soil

P. O. Kisinyo, P. A. Opala & S. O. Gudu · International Journal of Plant & Soil Science · 2019

Soil acidity, low level of nitrogen (N), phosphorus (P) and soil organic matter are major constraints to sorghum production in Kenya. We investigated the effect of farmyard manure (FYM) and combined application of inorganic nitrogen and phosphate fertilizers applied as calcium am...
