Project Description

Intensively cultivated arable soils that have been used to grow annual crops for decades often suffer from low organic matter content and weak structure. This leads to the soil being susceptible to slumping, compaction and impeded drainage- often causing surface flooding after prolonged or intensive rainfall events- and results in poor crop growth. Prior to the use of chemical fertilizers soil fertility was regenerated using rotational grasslands containing legumes such as clovers. These provide an evergreen cover of soil and supports a larger carbon input via roots than annual grain and seed crops which have been bred to maximize yield, but also improve soil structure.

We have ongoing trials across a number of UK farms comparing species-rich herbal leys with traditional grass-clover leys for their effects on soil properties and soil biology- such as earthworm populations, and there are a number of important questions to be addressed such as how deep the different leys root, their effects on soil structure and biology, effects on mycorrhiza and how the leys influence the performance of subsequent crops after soil quality improvement.
