It comes to the attention of our course takers at our Well End Micro-farm that neighbouring farms are more or less making concrete of their soil.
We walk along public footpaths on some of our courses and it can be clearly seen how the continual deep ploughing brings up the layer of thick sticky clay (the London clay we are based on). Not only that, this continued practise after many many years has even brought up the next lower level in the soil structure and that is shale.
We can see these layers clearly visible in our ‘lake’ excavation where below the clay layer there is a layer of shale. Mixing this with the clay layer in the deep ploughing process is making more or less a concrete of the top soil.
