In a system of summer fallow once in 3 or 4 years for the production of wheat, plowing for the fallow is done in May or early June. At this time moisture conditions are usually favorable for rapid decomposition of straw and the whole summer period is allowed for it. Through the energy, furnished by straw there may even be additions of nitrogen by free fixation. But for the second or third crops after fallow, it is essential that any turning under of stubble and straw be done immediately after harvest and the soil packed order to favor rapid decomposition.
