Response of "Jonagold" apple trees to Ca, K and Mg fertilization in an andisol in southern Chile
The effects of Ca, Mg and K fertilisation on the growth, yield, fruit quality and mineral concentration of the fruits and leaves of 'Jonagold' apple trees that were grown in an Andisol in southern Chile were analysed. In general, the Andisols in this area contain low reservoirs of these el...
