Mount Vernon, Maine, June 9, 2022- Woods End Laboratories LLC, a US based leader in agricultural soil health testing, announced that Rebecca Harvey, PhD has joined the organization as Chief Executive Officer. Rebecca will lead the organization to further grow its...

Recent tests comparing Solvita’s compost maturity test with infrared spectroscopy have revealed that the Solvita “Hi-CO2” gel corresponds quantitatively to a wide range of CO2 levels typical of active composts. Solvita for compost was designed empirically to indicate...

Dairy farm soils tend to exhibit high biology activity, credit due to the microbe-stimulating effect of long-term manuring. How well can this be detected with various respiration protocols? Woods End Laboratories examined soils from 62 dairy farm soils in three New...

A recent Soil Sieving Study examines how soil sieving for proficiency samples affects soil health test parameters. The work, a collaboration of Brinton and the Utah State PSC appears in the international peer-reviewed Agriculture Research and Technology Journal. A...

The Solvita soil test method has been published in more than , a recent tally shows.  A nearly equal amount of published papers report the Solvita compost test, a widely-popular procedure that combines CO2 and NH3 emissions to obtain a useful index for practical...

Solvita is a leading commercial test worldwide for soil CO2 respiration (and compost maturity) and is often in comparisons with newer soil respiration methods vying for market share.  Such is the case in a recent study by Oklahoma State University which proposed a...

Solvita announced quantitative recovery of nitrate nitrogen via a one-step chemistry conversion, using a Solvtia SLAN probe, “a small feat of basic chemistry” says inventor Brinton.  The Solvita SLAN test normally detects ammonia, ammonium and amines released when...

Have you wondered if limestone in soil can affect a CO2-respiration test? Or, what the difference is in measuring soil respiration for 1-day "CO2-Burst" versus 3 or 7-days? Many of these questions are topics of a series of short, technical memos on the theme of...

Woods End Laboratories has announced the release of , a rapid laboratory method for measuring water-stable soil aggregates. The new product was created to help soil labs complete the , which evaluates physical in additon to biological and chemical components of the...

Scientists critical of soil health testing often stress absolute differences between soil labs performing tests. But what about ranking? Rank-Order statistics focus not on the absolute numbers but on whether labs are similarly distinguishing one type from others, an...
