Aerial application of fertilizers may also be used in locations inaccessible to tractors, as described in Fertilizer Applicators and Plant Protection Equipment (EOLSS on-line, 2002). Both pressurized (typically using ammonia) and nonpressurized liquid fertilizer applicators are also described. Protection of plants from diseases and pests is normally achieved by atomizing a liquid formulation containing the active pesticide ingredient through a small nozzle under pressure and spraying onto, beside or beneath the crop canopy, or by using granular pesticide applicators.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.
