Crop fields: Crushing the stones or rock picking?

Recent studies have shown the advantages of breaking up soils instead of crushing stone.

Crushing the stone means leaving on the same ground the stone that already existed, simply fragmented. This fact has consequences that will affect the farm forever:

- The size of the crushed stone will be in many of the fragments greater than 20mm in diameter.

- The fragments of some types of stone can be very sharp and can cause punctures in the wheels.

- There are stones or conglomerate formations formed by certain minerals, which once crushed and mixed with the soil, can make the soil infertile and unproductive. One of these minerals found in many stones is calcium or limestone, which can generate chlorosis (lack of chlorophyll) in crops.
