Information for winegrowers in Tanzania
|
Sandy soil has a very low fertility due to its low CEC value (Cation exchange capacity). The CEC value is almost entirely dependent on the amount of humus present. However, the importance of increasing the organic matter in this soil is completely unknown. It is recommended to apply and irrigate fertilizer. This eliminates any form of soil life, and due to the absence of the 'clay-humus complex', there is a massive leaching of nutrients.
