돈분액비 시용이 트리티케일 생육과 토양의 화학적 특성에 미치는 영향

Abstract

As part of the agricultural natural circulation, the present study was performed. Recently, there has been the movement toward reusing the Liquid Pig Manure as an alternative fertilizer sources for agricultural lands. For instance, LPM (Liquid Pig Manure) liquid fertilizer has been developed and widely used in Korea. However, the impacts of LPM on both agricultural environment and crop triticale yield have not been investigated yet. The experiments were studied on paddy field after treatment of LPM on plant height, root length, plant length, dry matter yield and soil chemical properties. The effect of LPM by application on triticale was more increased plant height, root length and plant length than the Control. Chemical soil characteristics were not significantly different between on Control and LPM. Soil pH, OM, TN, P2O5 and exchangeable cation of triticale (X Triticosecale wittmack) appeared to be lower than before the treatment. Dry matter yield were produced 834.3kg 10a-1 of in LPM plot and 684.4kg 10a-1 in Control plot. In these results show abbreviated as the application of LPM increases the yield index of triticale. However, the properties of paddy soil were not affected by the LPM application.
