Generally, the addition of organic materials will improve the <br /> porosity of heavy clay soi I s and improve the water holding capacity of <br /> extremely sandy soils. On sites where these different soil conditions <br /> exist, it is recommended that a design professional with experience in <br /> soil modification be employed to recommend the proper amendments. <br /> For more information visit the NCDA Agronomic Services Soil Testing web <br /> page http://www.agr.state.nc.us/agronomic/sthome.htm <br /> SOIL PREPARATION <br /> Proper soil preparation is necessary for successful seed germination and root <br /> establ i shment. I t i s al so necessary for establ i shment of rooted spri gs, sod and <br /> woody plants. H eavi I y compacted soi I s prevent air, nutrients and moisture <br /> from reaching rootsthereby retarding or preventing plant growth. The success <br /> of site stabilization and reduction of future maintenance are dependent on an <br /> adequatel y prepared soi I bed. Fol I owi ng are the requi rements for preparati on <br /> of areas to be vegetated by grassing, sprigging, sodding, and/or planting of <br /> woody pl ants: <br /> General Requirements: <br /> • Preparation for primary/permanent stabilization shall not begin until all <br /> construction and utility work within the preparation area is complete. <br /> However, it may be necessary to prepare for nurse crops prior to <br /> compl eti on of constructi on and i nstal I ati on of uti I i ti es. <br /> • A North Carolina Department of Agriculture Soils Test (or equal) shall <br /> be obtained for all areas to be seeded, sprigged, sodded or planted. <br /> Recommended f erti I i zer and pH adj usti ng products shad I be i ncorporated <br /> into the prepared areas and backfill material per the test. <br /> • All areas to be seeded or planted shall be tilled or ripped to a depth specified <br /> on the approved plans, construction sequence and/or construction bid <br /> list. Ripping consists of creating fissures in a criss-cross pattern over <br /> the enti re surface area, uti I i zi ng an i mpl ement that wi I I not gl aze the si de <br /> walls of the fissures. Site preparation that does not comply with these <br /> documents shall not be acceptable. The depth of soil preparation may <br /> be establ i shed as a range based on the approval of the revi ewi ng state or <br /> local agency. Once tilled or ripped according to the approved plan, all <br /> areas are to be returned to the approved final grade. pH modifiers and/or <br /> other soil amendments specified in the soil tests can be added during the <br /> soi I preparati on procedure or as descri bed bel ow. <br /> • All stones larger than three(3)inches on any side,sticks,roots,and other <br /> extraneous materials that surface during the bed preparation shall be <br /> removed. <br /> Rev.5/08 6.11.3 <br />
