There was a short item on Radio 4 this morning just before 7AM about Harper Adams university in which they mentioned the development of lighter farm machinery to reduce compaction of the soil. One of the disadvantages of ploughing is that one of the rear wheels of the tractor drops into the furrow and compacts the sub soil forming a “pan” which then needs breaking up every few years with a subsoiler – yet another mechanical operation using yet more diesel!
No-dig is getting mainstream.
