Species breakdown in this mix
Buckwheat
This is a short term, aggressive weed suppressor. It is good at scavenging for phosphate in the soil, breaking it down and then making it available to subsequent crops after incorporation. It's especially useful in soils that suffer from phosphate lockup. With its quick growth, the plant can establish from seed in 8 - 10 weeks.
Berseem Clover
This is a short term legume also known as Egyptian clover. It provides fast growing biomass and nitrogen fixation when sown in warm soils.
Fenugreek
Traditionally the fenugreek plant has been used over the centuries as a herb and a spice in cooking and for medicinal purposes. In the UK there has been some trials carried out using the plant as a soil improving green manure. Due to its rapid growth it has been trialled in poly tunnels where productivity is high and gaps in the rotation for fertility building are short.
