Submit each sample, according to the quantity of soil required by testing laboratory, to <br />a competent laboratory approved by the Owner's Representative. <br />C. Provide analysis of soil samples for pH, salinity, ammonia, phosphate, potassium, <br />calcium, magnesium, boron, and sodium levels. Provide appraisal of chemical <br />properties, including particle size determination, and recommendations for types and <br />quantities of amendments and fertilizers. <br />3.03 PREPARATION <br />A. Clearing of Vegetation: <br />If live perennial weeds exist on site at the beginning of work, spray with a non- <br />selective systemic contact herbicide as recommended and applied by an <br />approved licensed landscape pest control advisor and applicator.

Soil preparation: <br />Loosen soil in all planting areas, and on slopes flatter than 3:1 gradient, to a <br />depth of six to eight inches (6" - 8") below finish grade. All debris, foreign matter, <br />and stones shall be removed prior to the placing of any fertilizers or conditioners. <br />Soil preparation is for all shrub planting beds, lawn hydroseeded areas and <br />sodded lawn areas. <br />2. Conduct the required soil tests and instruct the lab to include a minimum of the <br />following soil improvements in the recommendation on the soils report. <br />a. Soil Amendment: Two cubic yards (2 cy) per 1,000 square feet. <br />b. Gro -Power Plus: One hundred fifty pounds (150 lbs) per 1,000 square <br />feet. <br />C. If the lab recommends less than six cubic yards (6 cy) of soil amendment, <br />the excess bid amount shall be applied to the cost of any additional <br />recommended soil improvements, or returned to the Owner as a credit <br />3.

Fertilizer/Soil Conditioner: Broadcast 150 pounds of Gro Power Plus per <br />1,000 square feet in all planting areas and rototill to a depth of six to eight <br />inches (6" - 8"). Remove from the site any rock and debris brought to the <br />surface by cultivations. "Cultipack" all areas to receive sod or hydroseed. <br />E <br />
