Study on Summer Forage Crop Cultivation Using SCB (Slurry Composting-Biofilteration) Liquid Fertilizer on Reclaimed Land

Abstract

Until now, The experiment about the forage crop have been almost not conducted on the reclaimed land. Therefore, this experiment was carried out in order to know productivity of summer forage crop using slurry composting-biofilteration (SCB) liquid fertilizer on reclaimed land of Hwaong and Sukmoon in korea from 2008 to 2009. The forage crops used in this experiment were corn and sorghum×sorghum hybrid which are used as summer forage crops in South Korea. The experiment was treated with chemical fertilizer (CF), swine slurry (SS) and SCB liquid fertilizer. Dry matter (DM) yield of corn was higher than those of sorghum × sorghum hybrid in both reclaimed lands but the effect of SCB liquid fertilizer was not appeared. The neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents of corn were lower than those of sorghum × sorghum hybrid. The crude protein (CP) content and in vitro dry matter digestibility (IVDMD) of corn were higher than those of sorghum × sorghum hybrid. In generally feed values of corn were higher than those of sorghum × sorghum hybrid. The results of this study showed that summer forage crop cultivation using uses SCB liquid fertilizer on reclaimed land are possible.

Monitoring of Shallow Groundwater Salinity in Livestock Manure Applications to Reclaimed Tidal Land

“…Korea has about 155 600 ha of total reclaimed land as a result of mega reclamation projects. Reclaimed tidal lands developed in Korea provided quality cropland, mainly for rice cultivation, until 2000 (Choung et al, 2002;Jo et al, 2010).…”

“…The use of organic fertilizer affects soil property remediation due to changes of soil composition (Son and Cho, 2009;Choi et al, 2010). Applying organic manure to reclaimed tidal land would improve physicochemical and biological properties that can ameliorate soil organic matter, soil microorganism activities, cation exchange capacity (CEC), soil moisture-holding capacity and soil salinity (Ashman et al, 2003;Ghoname and Shafeek, 2005;Son and Cho, 2009;Jo et al, 2010). Low concentration liquid manures (LCLM) may be considered as organic fertilizers for reclaimed tidal land to provide nutrients.…”

“…Son and Cho (2009) studied the effects of organic material treatment on aggregate formation. Jo et al (2010) studied the productivity of summer forage crops by applying SCB liquid manure. From these studies, it is found that applying proper manure in reclaimed tidal lands can improve plant growth and also plant growth can reduce soil salinity in reclaimed tidal lands.…”
