Abstract:
1. Pot experiments have shown that the presence of increasing proportions of chalk in a soil up to a certain limit tends to produce a better yield of crops. 2. When chalk is replaced by an inert substance like sand, a similar, though smaller, increase in crop yield is obtained. 3. This is attributed, among other factors, to an improved physical texture of the soil induced by mechanical opening.
