Effects of Fused and Rock-P Application on the Available Phosphorus and P Uptake by Plants Grown in Volcanic Ash Soils = 화산회토양의 초지에서 용성인비와 인광석시용이 토양의 유효인산과 목초내 P함량에 미치는 효과

다국어 초록 (Multilingual Abstract)

An experiment was carried out to find out the effect of fused-P and rock-P applications to mixed pasture species (orchardgrass ; Dactylis glomerafa, and ladino clover; Trifolium refiens) grown in Cheju volcanic ash soils Back soil when compared with very dark brown soil. is generally lower in available phosphorous Phosphorus uptake in pasture species lowers its dry matter yield. In the case of carrier free, phosphonis application increased dry matter yield more than no phosphorus, while carrier was treated(0.5 mole KH_(2)PO^(4)) there was no dif-ference in the dry matt,er yield and available phosphorus between no P and P applications. When applied to pastures. fused-P compared with rock-P gave higher dry matter yields and increased P-uptake.
