“Closing the Crop-Yield Gap through Better Soil and Better Management”

Click here for brochure/How to order

This book argues for better soils and better crop management. This book is based upon five claims:

1. The gap between average crop yield and what better growers are getting can be filled. This goal is number one.

2. Even the gap between yields of better growers and record yields can become more narrow. This is goal number two.

3. These goals can be largely met with creation of better soil and with more attention to management details. The use of the concept of the Law of the Maximum will be essential.

4. The goals can be met without new breakthroughs in plant biology. Such advancements, however, will be welcome.

5. The principles outlined can also be used for very small-scale agriculture as well as for large-scale agriculture. Slight modifications may be necessary for some.
