If the required soil moisture is not present at these times, the seeds may become the target of predation by insects and other animals. Along with soil moisture, surface conditions also play a key role in the success of aerial seeding and establishment of seed. [18] The best soil surface conditions are those that are moist and friable.

Air sparging, also known as in situ air stripping [1] and in situ volatilization is an in situ remediation technique, used for the treatment of saturated soils and groundwater contaminated by volatile organic compounds (VOCs) like petroleum hydrocarbons, [2] a widespread problem for the ground water and soil health.
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 ...
To reduce drift of the sprayed materials, agricultural pilots attempt to fly just above the crops being treated. Fields are often surrounded by obstacles such as trees, telephone lines, and farm buildings. Purpose-built agricultural airplanes have strengthened cockpits to protect the pilot if an accident occurs.
By November 2019, the German Aerospace Center estimated large electric planes could be available by 2040. Large, long-haul aircraft are unlikely to become electric before 2070 or within the 21st century, whilst smaller aircraft can be electrified. [84] As of May 2020, the largest electric airplane was a modified Cessna 208B Caravan.
