The Essential Nutrients Availability for Sustainable Production of Soybeans (Glycine Max [L.] Merril) in Garba Chede, Maihula District Bali Local Government of Taraba State, Nigeria

The availability of essential nutrient elements in soil of an area is a pointer to the fertility capacity in supporting agricultural productivity in sustainable manner. Macro and micro nutrients governs the fertility of soil that controlled crop growth and yield, the study was carried out to determine the availability of these essential nutrient elements as N P K Mg SCa Na Zn Mn Cu Fe in soil of Garba chede,Maihula District of Bali sufficient for production of Soy beans. Field survey was conducted where soil samples (0 – 15cm) were collected and analyzed for the levels of these macro and micro elements in the soil using the standard laboratory procedures.The Organic carbon, Soil pH, and Phosphorus levels in the soils were within low to medium (0.53 – 1.32, 4.6 -6.7 and 5.12 -27.21) respectively. The concentration of K (170 mg/kg – 459 mg/kg) and Mg (0.4 cmol/kg – 3.26 cmol/kg) analyzed in the soils are sufficiently higher while CEC and Ca contents of the soil are low (6.4 – 15.2 and 1.17 – 1.98).The levels of essential micro nutrient elements determined in the soils under studied were higher. The essential nutrient elements analyzed in the soil can support soybean production only few of these elements that indicated low availability needs to be supplied with organic manure and inorganic fertilizer in a balanced form to increase the yield of soybeans in Bali.
