1. A strongly acidic lawn, with a 5.5 pH, wastes 33% of the fertilizer that is applied to it and prevents most nutrients from being available to the grass plants.
2. Moss and weeds thrive in acid soils.
3. Acid soil increases thatch build-up, which prevents grass clippings from decomposing.
Many factors contribute to the existence of the low-pH acid soil in the Northern Virginia region. Clay soils common in this area exist to low pH levels. One often overlooked factor, increased acid rainfall, also damages vegetation in this area. Other factors include over-fertilization and imbalanced nutrients, poor mowing practices, tree roots, leaves and debris. Moss and weeds tend to thrive in such conditions. Wasted fertilizer and increased thatch buildup also create low pH levels in the soil.
We at National Turf Service address these problems in several ways. Most importantly we have incorporated high-calcium, pelletized limestone as an integral part of our program each year. The two nutrients contained in limestone, high-calcium and magnesium, act as catalysts to help the grass plants fully absorb the proper amount of fertilizer prescribed and used by NTS for this area.
We at NTS firmly believe that by achieving a proper balance of available nutrients for the growth of lawns, we can combat unnecessary runoff of these materials in streams and waterways - thereby helping to protect the Chesapeake Bay Watershed and its tributaries. For these reasons, National Turf Service has south to properly apply and regulated all materials in an environmentally beneficial and safe program since 1970.
