Environmental Implications

This paper briefly reviews the developments that have occurred in the United States of America regarding farmer and grower provided soil testing and plant analysis services from the early 1990s to the present. Significant changes have occurred in terms of the type of laboratory providing these services, methodology, and instrumentation. Developing environmental implications related to soil testing and plant analysis will begin to impact the number and types of tests that will be mandated, and those who will be qualified to conduct these tests, as well as requirements for laboratory accreditation and certification. The results of a 1991 survey of soil testing and plant analysis laboratories are given.

Tissue Samples

Although over 3 million soil samples and over a half a million plant tissue samples are assayed in the some 450 soil-testing and plant analysis laboratories in the United States of America, both techniques are considerably under utilised by farmers. It has been estimated that <15% of the cropland is soil-tested each year and about 30-40% of farmers seldom soil test. Plant analysis is primarily used as a diagnostic tool, except for fruit and nut growers, many of whom test yearly in order to formulate fertiliser recommendations for next year's crop. Considerable standardisation of assay procedures and methods of reporting soil and plant analysis results have occurred in the last decade, although much has yet to be done. Laboratory accreditation and proficiency testing are current issues that will begin to impact the laboratories, while environmental issues will probably demand increasing testing by farmers to insure that fertiliser practices are not contributing to soil and water degradation. This paper reviews past, current, and future roles of soil testing and plant analysis in the U.S.A.

Phosphorus And Potassium

Abstract Soil tests are performed to determine the amount of nutrients available to plants so that fertilizer and lime recommendations can be formulated. In 1951, State soil testing laboratories had numerous extractants for determining phosphorus and potassium. Twenty years later, only 3 extractants each were used for phosphorus and potassium. In the United States, a regional approach produced standardized methods for several of the most common soil testing procedures. These detailed standard methods resulted from identifying procedural causes for variations in soil test results. For example, the amount of nutrient extracted varied by size and shape of extraction vessel and speed and time of shaking. Currently, terminology and expression of soil test results, and a search for a more universal soil extractant, i.e., one that can be used to determine several rather than a single nutrient, are 2 of the main areas of effort.

Perceived Behavioral Control

Community gardens offer numerous benefits, but there are also potential risks from exposure to chemical contaminants in the soil. Through the lens of the Theory of Planned Behavior, this mixed methods study examined community gardeners’ beliefs and intentions to conduct heavy metal soil testing. The qualitative component involved five focus groups of community garden leaders in Atlanta, Georgia. Qualitative analysis of the focus group data revealed that heavy metal soil contamination was not frequently identified as a common gardening hazard and several barriers limited soil testing in community gardens. The focus group results informed the development of a questionnaire that was administered to 500 community gardeners across the United States. Logistic regression analysis revealed that the soil testing intention was associated with attitude (aOR = 2.46, 95% CI: 1.34, 4.53), subjective norms (aOR = 3.39 95% CI: 2.07, 5.57), and perceived behavioral control (aOR = 1.81, 95% CI: 1.10, 2.99). Study findings have implications for interventions involving community garden risk mitigation, particularly gardens that engage children and vulnerable populations.

Transplant Organ

Prostate adenocarcinoma is the most common malignant tumor of men in the United States and is the third leading cause of death in men. Despite attempts at early detection, there will be 244,000 new cases and 44,000 deaths from the disease in the United States in 1995. Therapeutic progress against this disease is hindered by an incomplete understanding of prostate epithelial cell biology, the availability of human tissues for in vitro experimentation, slow dissemination of information between prostate cancer research teams and the increasing pressure to “ stretch” research dollars at the same time staff reductions are occurring.To meet these challenges, we have used the correlative microscopy (CM) and client/server (C/S) computing to increase productivity while decreasing costs. Critical elements of our program are as follows:1) Establishing the Western Pennsylvania Genitourinary (GU) Tissue Bank which includes >100 prostates from patients with prostate adenocarcinoma as well as >20 normal prostates from transplant organ donors.
