Ann: Successful OHD Cereal Crop Trials, page-553

Of course. I have never said i wouldn't use ohd if the numbers stack up. The point i want to get across is the 300% yield increase.

As a basic rule we use when applying something like urea is 1 for 2. So for every dollar we spend, we need to receive $2 back. If i spread $50ha of urea i need to produce an extra $100 of wheat. If spending $50 is only going to return me $75 the risk v reward is to great. So the big question is going to be can ohd give me a better return on investment then other options? Time will tell i honestly hope it can but it will take many years imo to find out
