Cover crop trial book 21

Background on the species and mixes used Plot 1 – Forage Rye A useful species that has the ability to lift and hold Nitrogen. Its wide sowing period makes it a flexible option, whilst its roots can hold the soil structure together. Plot 2 – Berseem Clover A rapidly growing species, that will fix nitrogen. Plot 3 – Crimson Clover An annual clover fixing nitrogen, that can be grown on poorer sites. Plot 4 – Radish type 1 A deep rooting radish, with the potential to reduce 90% of beet cyst nematodes. Plot 5 – Fodder Radish Another deep rooting species, that is quick to establish and improves soil structure. Plot 6 – Spring Vetch & Plot 7 – Winter Vetch Slightly slow to get growing and established, but once it’s growing it can fix N in a relatively short period of time. Plot 8 – Buckwheat A brilliantly fast growing annual crop, that will scavenge phosphate and reduce leaching. Not winter hardy, buckwheat will die back after a hard frost. Plot 9 – N Fixer The species in this mix have been chosen to maximise nitrogen fixation in their growing period. Plot 10 – Sprinter The use of black oats in this mix enable it to be an excellent weed suppressant and isn’t a host to root lesions or stubby root nematodes. Alongside with the vetch being able to fix nitrogen, this mix is a useful and popular option. Plot 11 – EcoCover The mustard element will be quick to establish and grow, while the rye fills in the bottom growth, aiming to supress weeds efficiently. Plot 12 – Green Reward Containing 7 different species, Limagrain’s mix has the ideal combination of rooting depths and biomass yields above ground, nitrogen fixation, weed suppression and fast establishment. Plot 13 – Soil improver With 4 species, this Limagrain mix still has the ability to cover the different rooting depths and will help retain moisture in the ground. Plot 14 – Commando mix Specifically designed by Limagrain as a biofumigant mix, as the species included have higher levels of isothiocyanates. These chemicals have the ability to supress soil borne pests, diseases, fungal pathogens and weeds. It can also help with compacted areas. Plot 15 – Red reviver Produce by Limagrain, it is designed as a mix to undersow cereal crops with, providing ground cover and an extra forage post-harvest.
