Numerous soil amendments are marketed for agricultural use. These products often have a low or slow solubility compared to conventional soil amendments such as limestone. Therefore, the  mode of action of these products needs further research and this project focusses on the effect of these products on the soil buffer capacity. The laboratory trials will investigate the effect of increasing rates os soil amendments on the pH buffer capacity and CEC of several soils. This project would suit a student with a background/interest in agronomy or soil chemistry. The outcome of the project is a better understanding of how these products reacts with soils, and the rate with which the products dissolve. The results may help explain some of the results observed in field trials.
