SR2: Cover, Catch, Forage Crops & Leys

SR2 contains soil dwelling Arbuscular Mycorrhizal Fungi (AMF) and Plant Growth Promoting Rhizobacteria (PGPR) that act to increase the effective root area of treated plants. This enhances plant efficiency through the increased acquisition of nutrients and water up-regulation of natural plant defences and the development of a framework for other beneficial soil microbes. Arbuscular mycorrhizal fungi (AMF) associate with 90% of all crop plants. By growing into the root, as well as accessing large areas of soil around the plant, these remarkable fungi effectively increase the uptake surface area of plant roots up to 700 times. Additionally plant defence mechanisms are improved by the partnership. Put simply, plants colonised by AMF are healthier and significantly more efficient at collecting water and nutrientsfrom the soil. Plant growth promoting rhizobacteria (PGPR) have the ability to fix atmospheric nitrogen and unlock soil-bound phosphorus. They work in synergy with AMF, which transport nutrients to host plants. PGPR support a robust plant immune system for healthier crops and produce phytohormones such as auxins and cytocinins, aiding growth and development of plants.
