四个地点的大麦试验表明,免耕可节约使用机具的费用,减少田间耕作费用,但产量较低.且需施用较多的除草剂.免耕的经济效益比常规耕作少48.77加元/公顷(变幅为18.43-68.79加元/公顷).本研究未涉及诸如土壤侵蚀、土壤结构及其养分变化以及增施除草剂的后果等长期效应.
Barley testing at four locations showed that no-till can save on the cost of using machinery and reduce the cost of field farming, but the yield is lower and more herbicides need to be applied. The economic benefits of no-till are 48.77 CAD / ha lower than conventional farming (Amplitude 18.43-68.79 CAD / ha) .This study does not address such long-term effects as soil erosion, changes in soil structure and nutrients and the consequences of herbicide addition.
