We own a parcel of land in Mallorca in which we want to use permaculture to be as self sufficient as possible. We have almond and olive trees and have set up a fairly productive vegetable garden. The soil is poor quality as we are up a hill. I notice it is lacking in iron as some plants show as being deficient. I would like to understand how to improve our growing in this Mediterranean climate and have learnt that I cannot grow the same way as I do in the UK.
