不同时间、地点、研究类型和作物类型对替代耕作系统（有机、减少投入、垄作和免耕）相对于传统耕作系统的盈利能力进行了比较和分析。收集到的信息可以进行673项单独的生产成本和盈利能力比较；其中包括206项有机耕作与常规耕作的直接比较，195项减少投入与常规耕作的比较，74项垄耕与常规耕作的比较，以及198项免耕与常规耕作的比较。研究类型（农场与研究试验站）在所有替代种植制度的经济比较中起主要作用。在最近（1986-1999）的研究中，与1985年之前进行的研究相比，减少投入和有机生产系统与传统生产系统相比不那么有利。研究发现，最大的决定因素是作物类型，因为一些作物，如茄子，似乎只在常规生产中表现良好，而其他作物，如柑橘类水果，在有机生产中表现得更好。
The results of studies of the profitability of alternative cropping systems (Organic, Reduced Input, Ridge Till, and No-Till) relative to that of conventional systems are compared and analyzed across time, location, study type, and crop type. The information collected allowed 673 separate production cost and profitability comparisons to be made; this included 206 direct comparisons of Organic to Conventional, 195 comparisons of Reduced Input to Conventional, 74 comparisons of Ridge Till to Conventional, and 198 comparisons of No-Till to Conventional. Study type (farm vs. research experiment station) plays a major role in the economic comparison of all alternative cropping systems. Time period also seemed to play a role, as Reduced Input and Organic production systems compare less favorably with their Conventional counterparts in recent (1986-1999) studies relative to studies conducted prior to 1985. The largest determinant was found to be the crop type, as some crops, such as eggplant, seemed to do well only with Conventional production while others, such as citrus fruits, did much better organically.
