Hi there, I'm currently working on two permaculture designs here in The Netherlands, northwest Europe. These are my first two designs. the properties are about 1,5 hectare each. In both designs i'm encountering the same problem. Both properties are recently bought and mistreated for decades. Year after year it was used by a the farmer that intensively produced corn, potatoes and occasionally used it for pasture. The (in one case sand, in the other case clay) soil is in very poor condition because of fertilizers and pesticides. One property is just bare soil, the other one is currently pasture. Basically we have to start from scratch, without any organic matter. In both designs a large part has to be transformed in forest. How can I start planting trees? While designing I want to advise on this and I have to keep an eye on the money. I dont think trees wil grow in this poor soil, so I dont think I can just start planting. What would be a good and preferably cheap methode of improving the soil conditions to start a food forest? Do I really need to bring in a lot of organic material such as compost? Thans for your answers!
