Readings with an electronic capacitance instrument were compared with yields from the same areas in natural veld of different heights, and from a grass?clover pasture. The regression of meter reading against oven?dry weight was determined. A highly significant regression was found in respect of the data from the grass?legume pasture and a significant regression from natural veld with a height of 2 to 6 inches. No significance was found in respect of either fresh weights or oven?dry weights of longer veld grass.
Dry matter content appears to be a limiting factor in the use of the instrument. From the data it can he seen that for significant regression a dry matter content of less than 40% is necessary.
