Abstract

Use of farmlands for food production is under pressure and providing food for a growing population is a global concern due to alternative land use and degradation, pest infestations, urbanization and industrialization which led to climate change and encroaches arable land; especially in drylands where water, fertilizer, land, and other farm input resources are scares and needs to be utilized efficiently to enhance crop yields. Soilless culture technology reduces the challenges facing in soil-based farming which could lower yields. Improving food production and access could be possible using soilless culture. However, limited and incomplete information is available to indicate the role of soilless culture in reducing land pressure and degradation in drylands. This review aimed to examine the role of soilless culture as climate change occurs to transform dryland vegetable farming, reduce land pressure and degradation. Data gathered from relevant and recently published peer-reviewed papers and converted into uniform measurement units, paraphrased, and discussed. Studies indicated that soilless culture efficiently uses water, fertilizer, and land by 90, 70 and 75%, respectively, with average yield advantage of 147.3 t. ha−1 over soil-based farming. Soilless culture avoids soil disturbance and reduces land pressure and degradation while promoting crop intensification through year-round production. It supports soil-based farming, minimizes the negative impacts of agrochemicals on the environment, mitigates climate change, and increases productivity in drylands. It is economically feasible, environmentally sound, and socially accepted.
无土栽培技术改造蔬菜种植,减少旱地的土地压力和退化
用于粮食生产的农田受到压力,为不断增长的人口提供粮食是一个全球关注的问题,原因是替代土地利用和退化、虫害、城市化和工业化导致气候变化和侵占耕地;特别是在干旱地区,水、肥料、土地和其他农业投入资源稀缺,需要有效利用以提高作物产量。无土栽培技术减少了土壤农业面临的可能降低产量的挑战。利用无土栽培可以改善粮食生产和获取。然而,表明无土栽培在减少旱地土地压力和退化方面的作用的资料有限且不完整。本文旨在探讨气候变化下无土栽培在改变旱地蔬菜种植、减少土地压力和退化方面的作用。从相关和最近发表的同行评议论文中收集的数据,并转换为统一的测量单位,解释和讨论。研究表明,无土栽培对水、肥和土地的有效利用率分别为90%、70%和75%,平均产量比土壤耕作高147.3 t. ha−1。无土栽培避免了土壤扰动,减少了土地压力和退化,同时通过全年生产促进作物集约化。它支持土壤农业,最大限度地减少农用化学品对环境的负面影响,减缓气候变化,并提高旱地的生产力。它在经济上可行,对环境无害,并为社会所接受。
