Extreme climate variability is a major factor threatening crop production in Arizona State. However, limited information exists on how growers are adapting with land‐use practices. Using data from the National Oceanic and Atmospheric Administration and the Agricultural Census (2012 and 2017) of the US Department of Agriculture, this study investigates trends of land‐use practices among small‐ and large‐scale growers and their possible effects on harvested cropland. From 2012 to 2017, there are reductions in total farmlands (−0.5%) and vegetable production lands (−4%) with varying temperatures, precipitation, and drought severity index. However, harvested crop‐ and vegetable land increased by 3% and 11%, respectively, which was mainly influenced by large‐scale growers. This coincided with an increase in sustainable land‐use practices such as conservation agriculture no‐till (103%), reduced tillage (71%), and cover cropping (123%) which are most popular among large‐scale growers. Manure application also increased by 30%. However, there were reductions in other practices such as intensive tillage (−9%), use of commercial fertilizers (−0.2%), nematicides (−63%), and chemical diseases control (−16%). Unfortunately, non‐sustainable practices (irrigation, insecticide, and herbicide application increased by 27%, 39%, and 10%, respectively. This study reveals potential benefits of sustainable agricultural practices in Arizona and a need for increased adoption among small‐acreage growers.

可持续农业实践是亚利桑那州大规模种植者增加耕地的驱动力:小规模种植者的悖论

极端的气候变化是威胁亚利桑那州农作物产量的主要因素。但是,关于种植者如何适应土地使用实践的信息很少。本研究使用美国国家海洋与大气管理局和美国农业部的农业普查数据(2012年和2017年),调查了小规模和大型种植者的土地使用实践趋势及其对耕地的可能影响。从2012年到2017年,随着温度,降水量和干旱严重性指数的变化,总耕地(−0.5%)和蔬菜生产土地(−4%)减少。但是,收获的农作物和菜地分别增长了3%和11%,这主要是受到大规模种植者的影响。这与可持续土地利用做法的增加相吻合,例如免耕农业(103%),减少耕种(71%)和遮盖作物(123%),这在大规模种植者中最为流行。肥料施用量也增加了30%。但是,其他做法有所减少,例如密集耕作(-9%),商业肥料的使用(-0.2%),杀线虫剂(-63%)和化学病防治(-16%)。不幸的是,不可持续的做法(灌溉,杀虫剂和除草剂的使用分别增加了27%,39%和10%)。这项研究揭示了亚利桑那州可持续农业做法的潜在好处,以及需要在小面积种植者中增加采用率。肥料施用量也增加了30%。但是,其他做法有所减少,例如密集耕作(-9%),商业肥料的使用(-0.2%),杀线虫剂(-63%)和化学病防治(-16%)。不幸的是,不可持续的做法(灌溉,杀虫剂和除草剂的使用分别增加了27%,39%和10%)。这项研究揭示了亚利桑那州可持续农业做法的潜在好处,以及需要在小面积种植者中增加采用率。肥料施用量也增加了30%。但是,其他做法有所减少,例如密集耕作(-9%),商业肥料的使用(-0.2%),杀线虫剂(-63%)和化学病防治(-16%)。不幸的是,不可持续的做法(灌溉,杀虫剂和除草剂的使用分别增加了27%,39%和10%)。这项研究揭示了亚利桑那州可持续农业做法的潜在好处,以及需要在小面积种植者中增加采用率。分别。这项研究揭示了亚利桑那州可持续农业实践的潜在好处,以及在小面积种植者中增加采用率的需求。分别。这项研究揭示了亚利桑那州可持续农业实践的潜在好处,以及在小面积种植者中增加采用率的需求。
