At the end of the day, all you really want to know is how much of what you need to put down to get your next crop off to a good start.

In addition to performing most of the popular soil tests (Mehlich III, etc.), TPSL®'s signature soil test is its Daubeny Plant Natural® Extraction Method Soil Test – and using continuously-updated proprietary nutrition standards, is calibrated against actual plant nutrient uptake.

By closely duplicating the way plants take up soil nutrients in all soils, your Plant Natural® soil report shows only the amounts of nutrient compounds that are actually available to the plant.

But more than just numbers, your Plant Natural® report provides consulting advice with color-coding to show at a glance the levels of nutrients available to plants - along with fertilization recommendations for your crop and soil.

Additionally, detailed multi-page write-ups of report interpretations and recommendations are optionally available (SAO-00).
