Organic lawn fertilizer adds organic matter to the soil, this improves soil structure and stimulates microbial activity. Natural fertilizers release nutrients slowly and this reduces the chance of salt damage (burn) to grass plants and minimizes the risk of nutrients polluting waters by runoff or leaching.
Water, air and organic matter are essential components of healthy soil ecosystems. All living organisms - including plant roots and soil microbes - need water and oxygen to live. Organic matter binds mineral particles into granules that form soils with good structure - improving air and water movement into the soil and increasing the amounts of water a soil can hold.
Soil microorganisms also depend on organic matter for food - it is their main source of energy. As soil microbes feed on organic matter, they release nutrients that are then used by plants. A major benefit of organic fertilizers - the nutrients are released slowly as the organic matter is decomposed my microorganisms.
When used consistently over time they have the potential to improve soil nutrient availability and reduce the need for additional nutrient (fertilizer) inputs.
benefit of using natural fertilizers is healthy soils resulting from the
addition of organic matter. Healthy soils lead to healthy landscapes.
Although generally safe to use around homes, nutrients from both natural AND synthetic fertilizers have the potential to harm the environment. These nutrients are considered pollutants when they find their way into lakes, rivers and streams. Therefore, it is VERY important to follow good fertilizing practices - proper timing, rates and application methods.
when finished! Sweep or blow fertilizer off of sidewalks, driveways
and roads to prevent them from washing into storm drains and
contaminating our water supplies.
