Soil tillage systems are predominantly concerned with the provision of an adequate seedbed to accommodate the subsequent crop seeding or planting operation and to provide an optimum environment for seed germination, plant establishment and vigorous crop growth. Traditional tillage systems involved breaking the soil crust with a human or animal powered implement or plow pushed or pulled through the soil.
The overall sequence of operations (Figure 8) is orientated towards protecting post-harvest product quality and minimizing loss due to deterioration occasioned by respiration, microbial activity, insects or rodents. Control of respiration (i.e. conversion of carbohydrates to carbon dioxide and water) in crop products is achieved by temperature reduction, most usually by refrigeration but also by periodic ventilation typically of the cold night air.
