Agricultural production by traditional methods is constrained by extremes in temperature and by extremes in the availability of water; freezing temperatures as well as droughts and waterlogging have long daunted farmers. When plastic film is used on the soil, the solar energy absorbed by the soil during the day is retained at night since the plastic film prevents water from evaporating. Higher night time temperatures and higher levels of moisture in the ground promote active micro-organisms, which diminish the need for fertilizer and improve the physical properties of the soil.
