Soil Testing

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).

The nutrient levels shown in your report will likely be much lower (especially in high-pH soils) than those reported by other labs, as the popular extractions also report plant-unavailable nutrient compounds - tied-up by native soil chemistry and often from salts of previous fertilizer applications building-up over time.
