Liming Turfgrass Areas Penn State Extension
2002年1月1日 To put it another way, if your Penn State soil test report recommends that you apply 50 lb limestone/1000 sq ft, it assumes that you will use a lime source that, at 50 lb/1000 sq ft, will raise the soil pH to the same extent as 50 lb of pure calcium carbonate/1000 sq ftThe primary goal of soil testing is to inform efficient and effective resource management Soil testing is the most accurate way to determine lime and nutrient needs Soil testing is also useful for identifying contaminated sites (eg, elevated levels of lead) The results provided on your soil test report reflect the properties of the sample you submitted and the testing procedures used Interpreting Your Soil Test Results Center for Agriculture, Food, This test method determines the specific gravity of coarse aggregates that have been soaked for a period of 15 hours (Figure 1) There are four determinations that may be made from this procedure They are as follows: Figure 1 Coarse Aggregate Gravity Apparatus A Bulk Specific Gravity (Gsb) (also known as Bulk Dry Specific Gravity)SPECIFIC GRAVITY OF COARSE AGGREGATE AASHTO T 年2月8日 faces on the coarse particles, and the quality of the • Giummarra (2009) reports a PI between 4 and 15 The limestone test items did not form any hard crust Guidelines for Road SurfaceCourse Aggregate
