The trials aimed to see if there is any benefit in using liquid instead of solid P and to see if the volume of water used to apply liquid P has an influence on yield by increasing the volume of soil in which the P is distributed at higher water rates... A second trial at each site compared a range of commercial forms of starter P. Data for sorghum is presented ... In the trials liquid forms of P showed no advantage either economically or agronomically over soild forms of P. The Kelvin site showed an obvious response to the highest rate of liquid P which we believe to be due to the placement rather than the form...
