The magnitude of the vertical movement of nutrients in the soil profile determines their contact with plant roots and leaching, thus affecting the timing and method of fertilizer application. This study aimed to assess the K mobility in the soil as influenced by rate and method of potassium chloride addition. The experiment was carried out in 1998, using 7.5 cm wide and 35 cm long PVC leaching columns. Potassium was applied at rates of 0, 150 and 300 mg kg-1 […]
