• • <br />S,orm, VV'-for <br />w effective practice in and and semi-arid regions where the climate prevents fast plant grovtiTh, <br />particularly during the dry seasons. In those areas, mulching or chemical stabilization may be <br />better for t^e short-term (see sections on Mulching, Geotextiies, and C; iemicai Stabilization). <br />I What to Consider <br />Proper seed bed preparation and the use of high-quality seed are needed to grow plants for <br />effective erosion control. Soil that has been compacted by heavy traffic or machinery may need to <br />be loosened. Successful growth usually requires that the soil be tilled before the seed is applied. <br />Tocsoiling is not necessary for temporary seeding; however, it may improve the chances of <br />establishing temporary vegetation in an area. Seed bed preparation may also require applying <br />fertilizer and/or lime to the soil to make conditions more suitable for plant growth. Proper fertilizer, <br />seeding mixtures, and seeding rates vary depending on the location of the site, soil types, slopes, <br />and season. Local suppliers, State and local regulatory agencies, and the USDA Soil Conservation <br />Service will supply information on the best seed mixes and soil conditioning methods.. <br />Seeded areas should be covered with mulch to provide protection from the weather. Seeding on <br />slopes of 2:1 or more, in adverse soil conditions, during excessively hot or dry weather, or where <br />heavy rain is expected should be followed by spreading mulch (see section on Mulching). Frequent <br />inspections are necessary to check that conditions for growth are good. If the plants do not grove <br />quickly or thick enough to prevent erosion, the area should be reseeded as soon as possible. <br />Seeded areas should be kept adequately moist. If normal rainfall will not be enough, mulching, <br />matting, and controlled watering should be done. If seeded areas are watered, watering rates <br />• should be watched so that over-irrigation (which can cause erosion itself) does not occur. <br />Advantages of Temporary Seeding <br />• Is generally inr_ p -isive and easy to do <br />• E ', .: tSnE:: p',,ant ccver i :-?Si .Mien conditions ar- _'J <br />v<<. `-,tie <br />• v..zES s6ls "s c thttic, and can r'Gvl _ lii 1?;.
