I’m very interested in having some gs4 mixes for mid tier scheme. The payment looks very attractive and I like the idea of soil conditioning. At the moment we have 2 year Italian ryegrass leys grazed in winter and till 1sr April then cut 3 times using 86kgs of N per cut. How many acres will I need to make same amount of tons of silage. I appreciate the quality will be better but we want bulk in the clamp
