Abstract

                                In the black soil areas of the Bellary District, farmers do not as a rule plough their land very deep, except once in six or seven years. The conditions that influence the adoption of this practice at such long intervals are summarised below. Deep ploughing cannot be given in the heavy black soils of this tract as and when the cultivator likes but has to be done only between the months of December to March. The period is determined by the rainfall of the tract and the nature of the soil. The normal distribution of rainfall in the tract is as below.
