Sod reduces drainage
The sod slows down the speed and reduces the flow of running water, allowing most of it to be absorbed into the soil. This prevents many collected pollutants and other chemicals from rainwater to be transmitted to our water system. Instead, they go to the soil where they can be safely destroyed. Drainage and the followed erosion of the soil are considered to be one of the main reasons for the pollution of our water sources. Some researchers recommend lawns to be designed in order to serve as water collectors and filtration areas for contaminated water.
Prevention of erosion
As soil erosion is becoming an increasing problem, grass can play a vital role in reducing losses. Thanks to its fibrous root system, sod digests and retains nutrients like phosphorus and micro elements. In this way the integrity and strength of the soil structure is preserved, otherwise the rain and wind carry the microparticles, the soil is destroyed and this leads to erosion.
The sod and its benefits to the air
As plants absorb carbon dioxide and emit oxygen into the atmosphere, grass is not an exception. Well-maintained grass can also help to reduce pollen production by preventing the growth of weeds that produce significant amounts of pollen. Dust and other air-born allergens are also caught in a dense texture on the grass.
The sod and its benefits of safety
Healthy and well maintained grass areas act as a barrier to fire and can prevent it from spreading. They also prevent the spread of harmful insects such as ticks and rodents invasion. With its soft surface, the sod is very suitable for recreational purposes – statistics shows that injuries are significantly less than artificial pavements. Natural grass offers safe and flexible surface for children.
The grass regulates the temperature
Sod is significantly colder than most surfaces, fifteen degrees cooler than concrete and thirty degrees than synthetic grass. The process of moisture release has a cooling effect that greatly reduces the air temperature around the grass areas. Studies show that the amount of heat emitted from bare soil or poorly maintained grass is significantly greater than that of a healthy and well-maintained sod.
Pollutants such as hydrocarbons and heavy metals that are harmful to the health of human, plant and animal are often absorbed in the soil where these substances can be decomposed by bacteria, fungi and other microorganisms. The fibrous root system of healthy sod provides both the living environment and the energy source for these microbial populations to make them more productive.
Helps in the presence of noise
Studies show that if grass is planted on a slope next to a noise source, noise can be reduced by 8 to 10 dB. The treated noise becomes softer and less irritating.
