CULTIVATION is the most important cultural operation under dry farming, and therefore a systematic scientific study of the changes which cultivation brings about in a soil is very desirable. So far no work has been reported from India in which the effect of the different cultivation practices on soil has been studied. The testing and use of tillage implements have been governed by empirical practices. Implements have been accepted or rejected only by trial and error methods.. No attempt has been, made to analyze the changes which are brought about in a soil by using these implements. If proper selection of implements is to be made and suitable cultural practices are to be evolved, the precise effect of the implements on the soils will have to be determined. In the investigation reported here, an attempt has been made to determine the size, amount, arrangement, and physical and chemical characters of soil aggregates formed by the use of different implements.
