Abstract

Soil health can differ across cropping systems because of variation in edaphic and management factors. We evaluated how biological indicators of soil health (soil organic matter [SOM], permanganate oxidizable carbon [POXC], mineralizable carbon [MinC], autoclaved-citrate-extractable [ACE] protein, and potentially mineralizable nitrogen [PMN]) compared across four common Wisconsin cropping systems: grazed cool-season pastures, forage-based rotations that included perennial legumes or grasses, annual rotations receiving manure, and annual rotations receiving synthetic fertilizers. Biological indicators of soil health were up to 195% greater in pastures than other cropping systems. MinC, POXC and PMN were 10%–90% greater in forage-based rotations than annual cropping systems, but only MinC and POXC were greater in annual systems with manure compared to those without manure by 35% and 7%, respectively. Perennial vegetation and livestock integration offer the greatest potential to increase biological indicators of soil health in agricultural lands.

具有多年生植被和牲畜一体化的种植系统促进土壤健康

由于土壤和管理因素的差异，不同种植制度的土壤健康状况可能有所不同。我们评估了土壤健康的生物指标(土壤有机质[SOM]、高锰酸盐可氧化碳[POXC]、矿化碳[MinC]、蒸压柠檬酸盐可萃取蛋白质[ACE]和潜在矿化氮[PMN])在四种常见的威斯康星州种植系统中的比较:放牧冷季牧场、牧草轮作(包括多年生豆科植物或禾本科)、每年轮作粪肥和每年轮作合成肥料。放牧土壤健康生物指标比其他耕作制度高195%。草料轮作系统的MinC、POXC和PMN比一年生轮作系统高10% ~ 90%，但一年生轮作系统中只有MinC和POXC比一年生轮作系统分别高35%和7%。多年生植被和牲畜的结合为提高农业用地土壤健康的生物指标提供了最大的潜力。
