Improving soil biology for better yields

keith-gouldingSoil biology plays a vital role in maintaining healthy, sustainable soils and increasing it a key part of LEAF’s Integrated Farm Management.  Professor Keith Goulding, Sustainable Soils Research Fellow at Rothamsted Research, explains that providing growers with a greater depth of knowledge on the physical, chemical and biological complexity of the soil environment is key to addressing the current threats to soil sustainability.

Healthy soil is fundamental to food security, ecosystems and life.  90% of all the food we eat is grown in soil, feeding a global population that has increased to 7.3 billion people. Healthy soils provide a variety of vital ecosystem services such as nutrient cycling, water regulation, flood protection, and habitats for biodiversity.

Soil biology is essential for healthy and sustainable soils.

The conservation and improvement of soil is among the highest priorities of any farm. Routine analysis, maintenance and improvement of physical, chemical and biological soil health helps ensure soil’s long term fertility and builds organic matter, while reducing the risk of erosion, structural degradation, compaction and associated environmental concerns, such as flooding and drought. Good soil husbandry increases yields and profitability.

Soil biology is essential for healthy and sustainable soils.  Helping growers get a better understanding of the role of soil biology in key processes vital for growth of plants such as nutrient cycling (decomposition, mineralisation, immobilisation and denitrification) is vital to the way they think about, manage and protect soils.

What is soil biology? What is soil organic matter and why is it important to soil biology? How can we measure and increase it?  These are all questions that I’ll be addressing at a one day course, run in partnership with LEAF and Artis Training.  Aimed at advanced practitioners, the course will help growers get a better understanding of the factors affecting soil biology, and the role of soil organic matter in improving soil structure, aeration, water and nutrient supply.  We will also provide practical strategies to help growers measure and maintain soil organic matter, exploring sampling and tillage.

Providing growers with a greater depth of knowledge on the physical, chemical and biological complexity of the soil environment is key to addressing the current threats to soil sustainability and the protection of this precious resource.  It’s an exciting and challenging area where farmers have a central role to play.

About the author:

Professor Keith Goulding is the Sustainable Soils Research Fellow at Rothamsted Research, a LEAF Innovation Centre. He joined Rothamsted Research in 1974 and gained his PhD at Imperial College in 1980. His research has included the supply to crops of potassium and phosphorus from the soil, ion exchange, acid rain, soil acidification and liming and nutrient, especially nitrogen, cycling.

‘Improving soil biology for better yields’ is a one day course run by LEAF and Artis Training, aimed at accomplished practitioners.  It takes place on 18th January 2017 at JSR Farms Ltd, a LEAF Demonstration Farm.   The course costs £240 (inc VAT) but LEAF Members qualify for a 15% discount making the course £204 (inc VAT).
