Description
Conservation Agriculture (CA) describes farming systems where the soil is not tilled, crop residues remain on the soil surface, and crop rotation is practised. CA emulates as closely as possible natural vegetation systems. This chapter presents the benefits of CA to farmers and society. The first section outlines the benefits to farmers from the adoption of CA which include fuel, labour and time savings, reduced soil erosion, improved crop water relations, increased machinery efficiency, increasing soil organic matter levels and fertility, increased levels of soil biological activity, and, allied with these benefits, increasing crop yields over time. The next section covers difficulties experienced with adoption of CA which include weed control, competition for crop residues, managerial capacity, poorly drained soils and crop diseases. The authors go on to discuss the benefits to society resulting from CA adoption on the farm and landscape. The chapter concludes with a section on what can be done to help farmers considering CA.
