That would explain the wet spots drying up. Now some of these spots have been planted every year for several years-even in the past 5 wet seasons. Also, I've noticed that the ground doesn't seem to crack open during dry spells as much as cultivated fields nearby. Herbicide and commercial fertilizers certainly have been reduced without reducing yields. I'm sure the organic matter has increased over the years of zero-till and the soil tests seem to indicate higher fertility levels.
Nature can make soil good or poor quality and quality can and does change.
Man can make soil quality change also from good to poor. But, also we can improve soil quality, but at a much slower rate than we can destroy soil quality. Soil quality on my farm has definitely increased through years of zero-tillage. We didn't inherit this land from our parents, we are borrowing it from our children. From every heart, one prayer That all men live as one with nature, and peace reign everywhere.
