Summary
This review synthesises existing literature on the critical functions of micronutrients in crop production, covering their roles in plant physiology, consequences of deficiency, and management options including soil and foliar applications. Drawing on a broad body of agronomic research, it likely highlights the widespread nature of micronutrient deficiencies in agricultural soils globally and their implications for both yield and produce quality. As a single-authored narrative review published in a food, agriculture and natural resources journal, it serves as a reference overview for researchers and practitioners working on soil fertility and crop nutrition.
UK applicability
Although the review is international in scope and likely draws on research from a range of agro-ecological contexts, the principles governing micronutrient cycling, deficiency diagnosis, and correction are broadly applicable to UK arable systems, where deficiencies in zinc, boron, and manganese are recognised issues on certain soil types.
Key measures
Crop yield response to micronutrient application; micronutrient concentration in plant tissue and soil; deficiency symptoms and threshold levels
Outcomes reported
The review examines the functions of key micronutrients (such as zinc, iron, manganese, copper, boron, and molybdenum) in crop growth, the consequences of deficiency, and agronomic strategies for correction. It likely reports on crop yield responses and quality parameters associated with micronutrient management across diverse farming contexts.
