Potential impact of compost tea on soil microbial properties and performance of radish plant under sandy soil conditions - greenhouse experimentsAustralian Journal of Basic and Applied Sciences, 10(8) April 2016, Pages: 158-165
Abstract: Compost tea application to the soil improves soil properties and decreasing the need for chemical fertilizer as well as promoting the growth of plant. Therefore, an experiment was conducted at the greenhouse of Faculty of Agriculture, Zagazig University, Egypt during to examine the effect of tea compost combined with chemical nitrogen on microbial populations, plant growth and nutrient uptake of radish plant in a sandy soil. The results indicated that population of bacteria, aerobic N2-fixing bacteria and fungi were significantly affected by tea composts while actinomycetes were not affected by the same treatments. Total number of leaves per plant was higher in tea composts and chemical nitrogen either individually or combined. Sprayed and irrigated plant with T2 gave the highest value of fresh and dry weight of roots (31.80 g plant-1 and 3.47 g plant-1, respectively) as well as, highest fresh and dry weight of shoots (54.10 g plant-1 and 6.58 g plant-1, respectively). It was observed that application of compost tea increased N, P and K uptake of radish leaf were about 150%, 92% and 253%, respectively compared with control. Interestingly, Compost tea combined with application of N mineral fertilizers was the best management system for Promoting radish growth and increasing soil microorganisms, nutrient uptake and decrease need for chemical fertilizer and that will lead to sustainable agriculture.
