The amount of lime you must add to correct pH depends not only on your soil type but also on its initial pH. For example, applying 5 pounds 464of limestone per 100 square feet will raise the pH of a sandy loam soil from 6.0 to 6.5. It would take 10 pounds per 100 square feet to make the same change in silty loam soil. However, if 5.6 was the initial pH of the soil, 8 pounds per 100 square feet would be required for the sandy loam soil, and 16 pounds per 100 square feet for the silty loam soil. There is no simple rule of thumb that applies to all soils.
How much is this going to cost me? Several studies estimate the cost of purchasing and installing an electronic health record (EHR) ranges from $15,000 to $70,000 per provider.1-5 Costs vary depending on whether you select on-site EHR deployment or web-based EHR deployment.
For example, some believe that Medicare coverage of patients with chronic renal failure requiring dialysis, which has an estimated cost-effectiveness of $50,000 or more per QALY, implies a societal judgment that treatments with a lower cost/QALY ratio are cost-effective and should be provided (22).he goal of this study was to quantify incremental cost-effectiveness of guideline-directed medical therapies for HFrEF. Our study demonstrates that not only is medical therapy of HFrEF with ACEI+BB+AldA cost-effective, but also that treatment with ACEI and BB is cost-saving compared to treatment with diuretics alone.
