When it comes to growing grass, fewer chemicals are used than when using seeds. Grass is a healthy, mature, professionally grown grass that is free of weeds and disease-causing pathogens. Fertilization is done regularly with a mixture of nitrogen, potash and phosphate. A pre-emergent is also used to discourage weed growth before they start. Top Turf uses very little herbicide on cultivated grass due to the intense program of mowing, irrigation and fertilization that naturally discourages weed growth.
However, in some cases it is necessary to use herbicides in areas that require them. The herbicide poses no threat to lawns, pets and humans, as long as it is used as directed. If you decide to treat your lawn at home, it's important to follow the instructions on the label, as improper use could be harmful to other plants or animals. As Grasshole states, Sod Farms earns its living from the land and would never do anything to harm their land like any farmer who earns his living from the land. Organic material is used as much as possible and the land is kept as fertile and healthy as any other process.
There are also concerns about the environmental impact of turf farms. One common myth is that growing grass damages the environment by removing nutrients from the soil and overusing water and harmful chemicals. Organic grass is grown on turf farms and delivered to your home for you to extend and replace your old grass. Every lawn farm I've ever visited or any other agricultural farm had ditches full of fish, turtles, snakes, lizards, beavers, and other birds or waterfowl.
