Few farmers would question the desirability of retaining stubbles, both for control of erosion by wind and water, and to return organic matter to the soil. While the present debate is focused on the short term management of stubbles, longer term effects also need to be considered.
The Department of Agriculture has several long-running trials intended to measure long term effects.

Nitrogenous Fertilisers For Cereal Production, M G. Mason

Among the many factors influencing crop response to nitrogen applications, the most important are the season, soil type, paddock history, time of application and source of nitrogen. Before deciding whether to use nitrogen on a cereal crop, which source to use and at what rate, the farmer needs some understanding of how these factors work.

THE sandplain soils and climate of the West Midlands area are primarily suited to grazing.
However, the place of cereals is receiving a great deal of attention in view of their advantages in the early stages of development, and the need for the diversification of farm production.

Cultivation : Does Haste Mean Waste?, H M. Fisher

Many farmers believe that increasing the speed of cultivation and seeding implements will cause deterioration of soils and reduced crop yields.
In a three-year trial on clover ley land at Wongan Hills higher cultivation speeds tended to increase rather than decrease wheat yields. There was some deterioration in the physical structure of the soil.
Bare Patch And Poor Emergence Of Cereals. 3. Crusting Of The Soil Surface, S C. Chambers
Bare Patch And Poor Emergence Of Cereals. 3. Crusting Of The Soil Surface, S C. Chambers
Journal of the Department of Agriculture, Western Australia, Series 4
In some seasons extensive bare patches occur in cereal crops sown on the heavier wheat belt soils.
Experimental results from Beverley indicate that the poor emergence in some of these plantings may be due to crusting of the soil surface.
Working the surface with light harrows may destroy the crust and improve emergence.
