Summary
This systematic review examines soil nitrogen sensing technologies relevant to precision agriculture, synthesising literature on detection methods and comparing their practical strengths and limitations. The authors identify key challenges in current nitrogen-sensing approaches and propose future research priorities to enable accurate, rapid and cost-effective soil nitrogen determination at field scale. The work addresses a critical gap in precision agriculture where reliable nitrogen monitoring is essential for optimising fertiliser application and reducing environmental losses.
Regional applicability
The methodological insights are broadly applicable to UK arable and horticultural systems where nitrogen management is central to productivity and compliance with water quality regulations. UK farmers and agronomists would benefit from the review's assessment of which sensing technologies are most practical and cost-effective for temperate climate conditions.
Key measures
Characteristics, performance, constraints and applicability of various soil nitrogen detection methodologies
Outcomes reported
The review synthesised soil nitrogen detection methods from peer-reviewed literature, compared their advantages and disadvantages, and identified current challenges and future research directions for nitrogen-sensing technologies in precision agriculture.
