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.
This study was conducted to investigate the effect of Actinomyces sp. and Bacillus sp., UnitedStates granular microorganisms and Japan granular microorganisms on turfgrass growth and thatch decomposing of creeping bentgrass in golf course by measuring turf color index, chlorophyll index, thatch content of soil, root length, turf density and chemical properties and thatch content of soil.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
