In many areas, grasses come back naturally after cattle are removed, but some fields might lay fallow even after they have been rested and water is made available. These areas are largely dominated by brush, such as mesquite and the earth is too hard for seeds to penetrate. CLO uses in these instances a Lawson aerator/seeder to break up the soil and knock back woody species. The large, spiked drums crush the brush and churn up the rock hard soil. The seeder deposit seeds in the small trenches. Depending of the timing of the the rainfall, one may not see results for several years. Over time, some of the mesquites start to grow again. But when using this machine, one establishes the base for healthy grassland habitat to come back.
CLO has aerated and reseeded more than 5,000 acres of grasslands with native grasses. It is important to use a variety of native seeds.
