3. Retains more moisture in the soil
Covering the ground with black plastic film significantly reduces evapotranspiration rates.
This means not only a decrease in the amount of irrigation or natural rainfall needed, but research shows that higher soil moisture levels also mean better growth and higher yields.
4. Keeps the soil warmer during cold nights
During the day, when the sun shines, the black plastic traps the heat rays and warms the ground underneath.
A high soil temperature protects the roots from damage caused by the cold.
5. Extends the growing season into the fall
Not only does black plastic allow you to start gardening earlier in the spring, but it also extends the growing season into the fall by keeping the soil temperature higher when the air temperature starts to drop.
It also acts as an insulator to maintain a more constant soil temperature, thus protecting roots from abiotic stress caused by climatic fluctuations.
