Soil hub

Improving soil health and structure is a key aim for many farming operations today and these presentations bring you some of the latest thinking from experts on the subject, as well showing what’s happening at farm level.

The hub programme aims to give you practical tips you can take away as well as food for thought from researchers and scientists.

Regenerative farming: A move to low-input systems

Mike Harrington, director and senior agronomist at Edaphos, takes a look at how regeneration leads the way when moving to a low-input system. Looking to promote a more holistic system of farming Mike will provide a view of how farming is adapting, with a particular focus on cropping scenarios and linking into nature for the future.

Edaphos is an independent agronomy firm focused on providing a well-balanced approach to agronomy. Mike bases his advice on the core principles of soil and plant health and his focus as an agronomist is to help move each farm to a better place, whilst keeping an all-round perspective on differing agricultural systems. Harnessing the soils stored resources to their full potential reflects the company’s philosophy.

How rebuilding carbon is key to boosting profitability on farm

This presentation sees Nick Woodyatt, soil fertility consultant and agronomist at Aiva Fertiliser, explain how rebuilding carbon in the soil is the key to boosting profitability on farm. Nick believes in a systems approach style of farming, highlighting the importance of carbon capture to increase yields with lower inputs.

Aiva Fertiliser is a UK manufacturer and distributor of products developed to support agronomic solutions for regenerative farming systems in aid of increasing efficiency, quality, and crop utilisation. Nick’s extensive knowledge on soil fertility, soil microbes and the carbon system comes from spending time travelling and understanding multiple soil systems around the world.

Alleviating and quantifying subsoil compaction in arable soils with Joseph Martlew (Cranfield University)

Subsoil compaction remains difficult to quantify at field-scale, and mechanical alleviation, although effective, weakens soil structure and increases the risk of recompaction. Cranfield University has joined forces with NIAB TAG to investigate alternate methods to quantify and alleviate subsoil compaction in arable soils, providing practical takeaways for growers.

Joseph Martlew, a researcher and agronomist at Cranfield University, reviews key findings so far on the impact of long-term rotation and cultivation approach on subsoil compaction, and the potential of two cover crop species to alleviate subsoil compaction through root bio drilling.

Cover crop management to reduce over-winter nitrate leaching losses

This presentation will provide growers with a look at cover crop management in an effort to reduce over-winter nitrate leaching losses. Dr Kate Smith, a soil scientist at ADAS, will demonstrate how early establishment is key to help reduce excess soil nitrogen at the start of over-winter drainage.

Farmer perspective: Investigating the benefits of no-till and cover crop systems

Richard Heady, a mixed farmer from north Buckinghamshire, is two years into giving the farm a soil health kick. Join Richard for a farm walk as he compares his conventionally farmed fields to no-till and cover cropped areas. He will dig into the benefits and drawbacks with both cultivation systems, sharing with growers what he has learned along the way.
