| Abstract/Contents: | Discusses the potential importance of "using the proper extractants for soil testing," explaining that "the chemical components of [alternative water sources] can cause dynamic changes in soil nutrient status and induce nutrient imbalances." Discusses two approaches to soil testing, "the sufficiency level of available nutrients (SLAN) [which] assesses the levels of plant-available macronutrients...and micronutrients...within a soil sample and provides important information on the soil's ability to supply a nutrient to the plant [and] the basic cation saturation ratio (BCSR) or [maintenance level] approach [which] determines the percentage of cation saturation levels on the cation exchange capacity (CEC) sites...[and] provides information on nutrient balances." Explains that "when properly used, these methods complement each other and provide more information than each one alone." Discusses chemical extractants, explaining that "the primary reason for many different extractants is that most were developed for soil conditions within a state or region." Suggests that "by far the better approach for determining the plant-available nutrient of a soil is the SLAN...using appropriate chemical extractants." Addresses specific nutrients, including phosphorus, potassium, calcium, magnesium, and sulfur. Lists key application points, such as "soil tests will not be accurate if the chemical extractant used is not appropriate for the soil conditions." |
