Nurse crops are expected to develop in two to five weeks and, <br /> with adequate maintenance, be an effective method of soil stabilization for <br /> a period of six months to one year. Nurse crops are not effective as primary <br /> long-term cover, however if properly maintained they can be an adequate <br /> cover and protection for the development of primary crops. <br /> The goal for a primary crop is for it to develop over a three-week to one-year <br /> period and be effective up to three years with a well-defined maintenance <br /> program. The long-term goal for a primary crop is the initial step toward <br /> a sustainable protective cover without the need of maintenance. Where the <br /> primary crop is intended for a managed lawn and landscape aesthetics, the <br /> effective period can be extended by a more intense maintenance program. <br /> Where native species are utilized and become established during the planned <br /> maintenance program, a permanent cover that will support future succession <br /> species should exist and require little or no additional maintenance or <br /> management. <br /> In uses of both nurse and primary crops,the development periods listed on the <br /> tables are optimal based on normal climatic conditions for the planting dates <br /> listed. The sediment and erosion control maintenance program must recognize <br /> that optimum temperatures and rainfall are the exception rather than the rule. <br /> The design professional needs to provide flexibility in the stabilization plan <br /> to address the potential ranges of temperature and moisture conditions we <br /> experience in North Carolina. <br /> 6.11.12 Rev.5/08 <br />
