Objectives of soil tillage related to field operations and soil management.

Abstract

The various tillage practices and field operations necessary for the growing and harvesting of crops are reviewed critically, with particular reference to possible ways of reducing these operations, with attendant benefits to soil structure and decreased costs. Particular reference is made to the possibilities of the reduction in cultivations made possible by the introduction of chemical techniques of controlling weeds. New minimum-tillage concepts and practices are discussed, including wheel-track planting and plough-planting techniques evolved in the USA for maize. See also Abs. 1182 and 1183.-P.J.B.
