provides the best technical information

Solvita tests for soils, compost, manure and grain are developed and manufactured by Woods End Laboratories in Mt. Vernon Maine, USA. Technical information and the latest developments in the USA are available at for those interested in applications of the technology.

Dr. W. F. Briton, the founder of Solvita systems points out the value of volumetric tests of respiration in constructed soil media as a key indicator of its good performance. Measuring volumetric respiration or the exchange of CO2 for O2 per unit volume may give a better representation of the true health of the soil environment.

More-and-more recycled organic composts are being added to potting mixes and soils, so there is a continual need to evaluate the maturity and stability of composts for particular applications.
