Use of soil tests among organic farmers in New England

Abstract

AbstractThis research explores the soil testing practices and interests of organic farmers in New England. Data were collected through telephone surveys conducted between December 1998 and January 1999 with 81 certified organic farmers. Organic farmers' commitment to the maintenance of healthy soils necessitates the use of soil evaluation tools. However, it is becoming increasingly understood that a complete picture of soil quality cannot be created solely through the use of laboratory soil tests. For example, many of the soil's critical physical characteristics are more suited to in-field assessment than to laboratory analysis. For this reason, utilization of both laboratory and on-farm tests was investigated. The use of evaluation tools can be influenced by the degree to which laboratory and farming services help organic farmers put test results into practice. Thus, additional questioning focused on the ease of understanding test results, the usefulness of soil test results and recommendations to organic farmers, and the likelihood of turning to expert help when soil management issues arise. Results indicate that in managing their soils, organic farmers in New England rely heavily on laboratory tests provided by public institutions. Most farmers were satisfied with laboratory services and found test results easy to interpret. Over one-quarter (31%) of the farmers surveyed were employing on-farm tests, but very few of these tests assessed physical or biological characteristics of the soil. Organizations most often sought by organic farmers for information on soil quality management were Extension services, followed by local organic certifying agencies, and state agriculture departments.
