This depends on soil properties and the availability of correlation data for turfgrass species in the desired region. This chapter describes common extracts and demonstrates their efficacy for phosphorous and potassium extraction with three soil samples from the North American Proficiency Testing program (http://www.naptprogram.org/) administered by the Soil Science Society of America. Fertilizer recommendations were made based on regional sufficiency levels from university soil-testing laboratories and the Minimum Levels for Sustainable Nutrition (MLSN) guidelines from the Asian Turfgrass Center and PACE Turf. Sufficiency Levels for Available Nutrients (SLAN) or MLSN guidelines are most appropriate for deciding how to fertilize turf. However, recommendations based on an inappropriate extractant, calibration, saturated paste extraction, or ideal ratios or of major exchangeable cations (i.e., Basic Cation Saturation Ratio) are inappropriate UR - https://library.oapen.org/bitstream/id/5dee1286-9a60-4c65-84ab-a8322ead37c0/9781801465090_web.pdf UR - https://library.oapen.org/handle/20.500.12657/61546 ER -
