Abstract:

The topic of this bachelor thesis explains an influence of phosphorus addition mixed with rice husk ash and lime on enhancing soil pH to increase the food productivity on sulphate acidic soils in Vietnam and potentially all of the Asia. We have created experiment with application of rice husk ash, lime and phosphorus and added these treatments to pots with Triticum aestivum. We have used regression analysis from measurement in the lab conditions to determine the amount of lime and rice husk ash to be added to the pots to reach optimal pH of the soil. We have determined that the phosphorus addition had no effect on increasing of soil pH and that the rice husk ash had higher influence on pH than the lime.
