Abstract

Regenerative Agriculture (RA) is used to describe nature-based agronomic approaches that aim to build soil health and crop resilience, minimize negative environmental outcomes, and improve farmer livelihoods. A benefit that is increasingly attributed to crops grown under RA practices is improved nutritional content. However, we do not know the extent to which RA influences crop nutritional quality and under what management approaches and context, can such effects be realized. A scoping review of recent literature (Web of Science, 2000-2021) was carried out to assess the evidence that RA approaches improve crop micronutrient quality. Papers included combinations of agronomic approaches that could be defined as Regenerative: "Organic Inputs" including composts and manures, cover crops, crop rotations, crop residues and biochars; "Reduced Tillage", "Intercropping", "Biostimulants" e.g. arbuscular mycorrhizal fungi; plant growth promoting bacteria, and "Irrigation", typically deficit-irrigation and alternate wetting and drying. The crop types reviewed were predetermined covering common sources of food and included: Tomato (), Wheat (), Rice (), Maize (), Pulses (Fabaceae), Alliums (), and "other" crop types (30 types). This scoping review supports a potential role for RA approaches in increasing the concentrations of micronutrients in the edible portions of several crop types under specific practices, although this was context specific. For example, rice grown under increased organic inputs showed significant increases in grain zinc (Zn) concentration in 15 out of 16 studies. The vitamin C concentration of tomato fruit increased in ~50% of studies when plants were grown under increased organic inputs, and in 76% of studies when plants were grown under deficit irrigation. Overall, the magnitude and reproducibility of the effects of RA practices on most crop nutritional profiles were difficult to assess due to the diversity of RA approaches, geographical conditions, and the limited number of studies for most crops in each of these categories. Future research with appropriate designs, improved on-farm surveillance and nutritional diagnostics are needed for better understanding the potential role of RA in improving the quality of food, human nutrition, and health.

摘要

再生农业(RA)用于描述基于自然的农艺方法,其旨在增强土壤健康和作物复原力,将负面环境影响降至最低,并改善农民生计。越来越多地归因于采用再生农业实践种植的作物的一个益处是营养成分得到改善。然而,我们并不清楚再生农业在何种程度上影响作物营养品质,以及在何种管理方法和背景下能够实现这种效果。我们对近期文献(科学网,2000 - 2021年)进行了一项范围综述,以评估再生农业方法能提高作物微量营养素品质的证据。纳入的论文涵盖了可定义为再生的农艺方法组合:“有机投入”,包括堆肥和粪肥、覆盖作物、作物轮作、作物残茬和生物炭;“少耕”、“间作”、“生物刺激剂”,例如丛枝菌根真菌;促进植物生长的细菌,以及“灌溉”,通常是亏缺灌溉和干湿交替灌溉。所综述的作物类型是预先确定的,涵盖常见食物来源,包括:番茄()、小麦()、水稻()、玉米()、豆类(豆科)、葱属(),以及“其他”作物类型(30种)。尽管这因具体情况而异,但该范围综述支持了再生农业方法在特定实践下提高几种作物可食用部分微量营养素浓度方面的潜在作用。例如,在16项研究中的15项里,增加有机投入种植的水稻籽粒锌(Zn)浓度显著增加。当植株在增加有机投入条件下生长时,约50%的研究中番茄果实的维生素C浓度有所增加,而在亏缺灌溉条件下生长时,76%的研究中番茄果实的维生素C浓度有所增加。总体而言,由于再生农业方法的多样性、地理条件以及这些类别中大多数作物的研究数量有限,再生农业实践对大多数作物营养特征的影响程度和可重复性难以评估。需要开展具有适当设计、改进的农场监测和营养诊断的未来研究,以更好地理解再生农业在改善食物质量、人类营养和健康方面的潜在作用。
