為探究中部地區春作高粱－宿根高粱－秋作玉米之輪作系統施用乾豬糞對旱作土壤肥力及土壤物理性之影響。於彰化縣埤頭鄉鹼性土壤及台中縣外埔鄉酸性土壤進行三年九期作試驗結果，顯出施用乾豬糞20 t/ha可以增加表土土壤有機質0.7～1.9%、NH4^+ 6～7 ppm、NO3^- 24～26 ppm及有效性磷291～301 ppm、交換性鉀17 ppm含量，並可降低表土（0～30 cm）的硬度0.32～2.2 kg/cm^2、總體密度0.04～0.11 g/cm^3，增進土壤水分含量0.3～5.0%及改善土壤滲透率220～327 mm/hr等土壤物理性質。

Effect of dry hog manure on soil fertility and soil physical characteristics in an upland cropping system (Sorghum-Ratoored sorghum-Corn) in central Taiwan was studied. The experiment were carried out for three years period in an alkaline soil at Pitou and an acid soil at Waipu. The application of dry hog manure at the rate of 20 t/ha could improve the following soil fertility and soil physical characteristics with increasing organic matter content to 0.7-1.9%; NH4^+-N to 6-7 ppm; NO3^-; available Phosphorus to 291-301 ppm; exchangeable Potassinm to 17 ppm; soil water content to 0.3-5.0%; and soil infiltration to 220-327 mm/hr, and reducing soil hardness to 0.32-2.2 kg/cm^2 and bulk density to 0.04-0.11 g/cm^3.
