A field experiment was conducted using 6 particle size segregations of calcitic limestone covering a range of mean diameters from 3 mm to 0.005 mm. These products were applied at rates of 2.5, 5 and 10 t per ha. No minimum particle size for maximum effectiveness was identified. Throughout the range...
