Summary
This review examines how mineral and organic fertilisation practices influence micronutrient (Fe, Cu, Zn, Mn, B, Mo) availability in soil and uptake by crops. The findings indicate that NPK treatments maximise certain micronutrients but suppress others, whilst farmyard manure application enhances soil solution concentrations of key trace elements. The authors note that whilst mineral fertilisers provide rapid nutrient availability, organic fertilisers support soil biological function but require higher application rates to meet crop demand.
Regional applicability
The study does not specify geographic location, limiting direct applicability assessment. However, the comparison of mineral versus organic fertilisation strategies and micronutrient availability mechanisms is relevant to United Kingdom soil management and organic farming certification requirements, where balancing nutrient supply with soil biological health is a key consideration.
Key measures
Soil and soil solution contents of Fe, Cu, Zn, Mn, B, and Mo; plant-accessible nutrient forms; pH effects on micronutrient availability
Outcomes reported
The study examined how mineral and organic fertilisation affected soil contents and plant accessibility of micronutrients (Fe, Cu, Zn, Mn, B, Mo). NPK treatments resulted in highest Zn, Fe, Mn, and Cu concentrations but lowest B and Mo; farmyard manure application significantly increased soil solution concentrations of Zn, B, and Fe.
