Oh yes, there ha , I mean there are economies of scale in agriculture, it's just that they're, the scope of them  er, is less than er the scope in manufacturing  so I mean, farms used to be a lot smaller and throughout this century, this last century we've witnessed an increase in farm size  alright, but the  I think the optimal, the optimal farm size  is  erm, I think it's about three hundred hectares  okay, er  erm, with three hundred hectares you'll produce a, a pretty squit proportion of erm total output   but farms used to be  sort of one, two, three, ten hectares in size as we've gone through the farms have amalgamated and increased in size and that's primarily due to economies of scale  , but there are a great deal of economies to be reached, once you've got a combine harvester, once you've got big machinery  alright.
