Summary
In a lysimeter investigation over four seasons it was found that under annual babala nitrification is apparently decreased to much the same extent as under perennial grass. This is as opposed to maize, sunflowers and soyabeans as annual crops. It is felt that this phenomenon could have profound practical implications in a biological approach to the maintenance of soil fertility.
