Abstract The area of land which man manipulates through cultivation is 3.2×109 ha; however, the impact from this system has been large. The soil-plant-atmosphere complex is very dynamic with the plant continually growing throughout a constantly changing atmospheric environment, i.e., radiation, temperature, and precipitation. However, a basis for all exchanges is the energy balance and all changes are made through this balance. Two impacts of this system are realized in water and wind erosion. Both are detrimental to agricultural land and proper management of the system alleviates the impact of these two forces. Other changes which occur are reduction in evaporation and soil temperature under crop cover. There is needed, however, a more thorough understanding of the energy exchanges throughout the growing season, especially as it applies to feed-backs between plant response and the environment, soil derived aerosols, and biogenic ice nuclei. These will provide a better understanding of how we manipulate this complex for maintenance of our world's food supply.
