Effects of Rubber Wood Ash on Soil Chemical Properties and Sweet Corn Growth in Acidic Soil
Keywords:
Acid soil, Rubber wood ash, Sweet cornAbstract
Rubber wood ash is a by-product from various industries or biomass power plants. There is a large amount of waste from fuel production. The ash of rubber wood is highly alkaline. It is also a source of important plant nutrients. The aim was therefore to investigate the effects of applying rubber wood ash on the chemical properties of the soil and the growth and nutrient uptake of sweetcorn in acidic soil. The experimental design was completely randomized with 3 treatments and 4 replications consist of control, added with lime at the rate of 1.5 times of lime requirement and added with rubber wood ash at the rate of 1.5 times of lime requirement. The results showed that application of rubber wood ash increased soil pH and macronutrients. In addition, this applying could be promoted greater growth and nutrient uptake of sweet corn compared to lime application. Our results suggest that rubber wood ash is able to substitute for conventional liming agents and it is also a source of plant nutrients
