Livestock liquid fertilizer Utilization study of Zoysiagrass growing in the field

Abstract

Recently, manure emissions associated with the numerical increment of the domestic hog-breeding have increased, but it has been banned from ocean dumping by the United Nations Convention in 2012. To find out the site for spraying in large quantity of liquid manure fertilizer, we selected one grass plantation, which has the largest amount of grass production, in Jangsung, South Korea. We spread not only chemical fertilizer but also liquid manure fertilizer on the zoysiagrass plantation and researched the effect on the grass growth and development, soil chemical property, and seepage water of dike.As the test results, spread by compounding chemical fertilizer and liquid manure fertilizer and it is possible to substitute for some chemical fertilizer in terms of nutrients accumulation and the grass growth and development. Additionally, it gives less effects to soil chemical property and is efficacious to effective microorganism growth of soil. Therefore, adding liquid manure fertilizer will lead to reduce almost all the amount of chemical fertilizer usage. It is also expected to help for livestock manure management and to influence reducing the production cost of the grass plantation. However, to spread liquid manure fertilizer contaminates water system. For this reason, monitoring continuously, we need to find out improvement plans of the fertilization method in order to increase the usage of liquid manure fertilizer.
