Basic Slag Alone.—At Koedoespoort, Pretoria, on sandy soils poor in lime, Prof. Watt found that a dressing of basic slag was beneficial to the leguminose crop grown in rotation with the maize {Watt, R. D., 2 J. At Potchefstroom the average yield for three years with the use of basic slag was. Fig. 125.—Effect of basic slag on maize (cf.

Nitrate of Soda Alone.—This is a very soluble manure and is apt to leach out in the drainage, so that in some climates there is little or none left for the following year ; but with the dry winters of South Africa some residual value may remain for the succeeding crop. Though an important element of plant-food, experiments show that the application of this manure is not always profitable. As it is one of the most.
