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 information about this and other EMR software and about how to select an EMR system for your practice, see âElectronic Medical Records: The FPM Vendor Survey,â January 2001, page 45, and the AAFP Web resource âHow to Select a Computer System for a Family Physicianâs Office,â www.aafp.org/x3700.xml .].he total cost for implementing the EMR system at Belleville Family Medical Clinic and one year of technical support was about $220,800 to $260,800. Although estimating the total cost of an EMR system prior to implementation is difficult, vendors can offer some help by providing hardware and training estimates.
