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.
Study participants on average spent $5,900 on purchases related to hardware, software, peripherals, and network connections. 1  About half of the practices averaged $3,094 for IT and other outside support costs. 2  These costs do not factor in overtime pay or other workflow inefficiencies. Averaged across all 30 practices, out-of-pocket expenses in the first 6 months of an implementation reached $6,516. In a similar study published in the March 2011 issue of Health Affairs, 26 primary care practices in North Texas implemented an EHR across their medical network. The researchers considered the hardware/software costs, as well as the staff members' time and effort to complete the implementation. They determined that a typical multiphysician practice would spend about $162,000 to implement an EHR, with $85,500 for first-year maintenance costs.
