To reduce drift of the sprayed materials, agricultural pilots attempt to fly just above the crops being treated.

Purpose-built agricultural airplanes have strengthened cockpits to protect the pilot if an accident occurs.
Soil conditioners may be used to improve water retention in dry, coarse soils which are not holding water well. The addition of organic material for instance can greatly improve the water retention abilities of sandy soils and they can be added to adjust the pH of the soil to meet the needs of specific plants or to make highly acidic or ...
By November 2019, the German Aerospace Center estimated large electric planes could be available by 2040.
