The Effects of Dolomitic Limestone and Gypsum on Chemical Properties of an Ultisol and Oxisol in Malaysia and on the Growth of Corn (Zea Mays L.)

The Effects of Dolomitic Limestone and Gypsum on Chemical Properties of an Ultisol and Oxisol in Malaysia and on the Growth of Corn (Zea Mays L.)

Ultisols and Oxisols are acidic in nature, with low CEC, low exchangeable bases, and high Al saturation, and are dominated by variable-charged minerals. The soils need to be ameliorated before they can be utilized productively. This study was conducted to determine the react ions taking place i...
