Summary
This narrative review synthesises peer-reviewed evidence on the agronomic, soil chemical, and ecological impacts of liming in UK farming contexts. The authors appear to conclude that whilst liming effectively raises soil pH and can improve short-term crop performance, its effects on soil biology, nutrient cycling, and long-term sustainability remain heterogeneous and context-dependent. The review situates liming within broader soil health frameworks, suggesting that benefits must be weighed against potential ecological trade-offs and interactions with other management practices.
UK applicability
Directly applicable to UK farmers and advisers, as the review focuses exclusively on UK soil and climate conditions. The findings inform guidance on optimal liming rates and timing to balance productivity gains with soil biological function and compliance with emerging environmental regulations.
Key measures
Soil pH, exchangeable acidity, crop yield, crop nutrient content, earthworm populations, microbial communities, plant species diversity, invertebrate abundance
Outcomes reported
The review examined the effects of agricultural liming on soil chemical properties, crop performance, and biodiversity outcomes across UK farming systems. It synthesised evidence on how liming practices influence soil pH regulation, nutrient availability, and ecological communities.
