There is a farm. It is farmed poorly for 20 year, little fertilizer used . Lot of weeds. Now this guy retires. You rent farm. Put fair amount of Fertilizer down( But you can afford to put enough to correct super low test on in 1 year) So you still have a low testing field. You clean up the weed with a big herbicide bill. At harvest time this field yield with best of what you have. But still has low PH and low test P and K compared to the rest of your farm. So where did the high yield come from?? Was it from the biodiversity of the weeds covering the land for the last 20 years????? That is my ??
