Water is bore hole or river so recycled rain that falls on field, yes didn't include straw but not used for human consumption, also didn't include calves or cull cow meat, I know it's not 100% 🤔
We grow oats at 2 to 2.5 ton/acre and on the same farm produce and about 8500 litres of milk or 8 ton/acre with the same rainfall(1600mm/year) looks like the oats are poor convertor of water 🤔
We've had 4 lucas, quality got worse with each machine, last one caught on fire and switched to a KV , which week point is the spout which keeps breaking, next machine will be a Mchale
