[QUOTE="N.Yorks., post: 6951202, member: 46426"] Sorry wrong term to use monoculture. Not a field of genetically identical/similar plants though. I think the mixed varieties offer different sets of genetic traits and in a given year the weather/disease pressure may affect one of the varieties but the others compensate as they are more able to withstand the pressure. In another year it may be a different set of conditions that favours the previous variety that didn't do well. Bit like having a stool with five legs, if one leg drops off then the others are still in place to do the job. Think the technical description is something like "resilience through biodiversity". Maybe benefits to the soil and environment would be less fungicide if you selected varieties with differing resistances, would also mean better gross margin too. [/QUOTE]
