When organic amendments such as manure or compost are soil applied it is difficult to predict response using ordinary soil tests. Several recent research projects have shed more light on intrinsic nutrient potential of natural fertilizers. The projects all employed Solvita tests including CO2-Burst and SLAN along with other conventional tests, and explored relationships to PMN and yields. Results clearly show that so
I like the analogy of an engine when talking about soil health. What is the size of your soil engine? Have you checked lately? Just like you use a dynamometer to measure the horsepower on a tractor you can use Solvita soil respiration to measure the horsepower of your soil.
Blogs provide an excellent opportunity to share information and ideas, discuss management practices and respond to questions from readers. In short – it is a place for a virtual agronomist, like myself to share information on soil health, i.e. what is it, how to measure it and how to manage it and discuss a host of other related topics and ideas.
Italy to many, is the birthplace of farming with a soil nomenclature system dating from 500 AD. In the mere distance of Maine to North Carolina they have all four major soil temperature groups – frigid, mesic, thermic and hyperthermic and 4-times the soil unit diversity of the USA.
Soil health testing needs its own set of calibrations and guidelines in order to have its potential fully realized. This has come into focus recently with studies on how soils behave biologically. Normally, when a soil dries out, a sudden addition of rain or irrigation water produces a well-known effect – the “CO2-Burst” – a surge of respiration by microbes springing into action.
Calling it a “health check for your soil” England’s largest independent soil testing firm NRM Laboratories (Berkshire & Norfolk) has introduced UK’s first Soil Health test. The analysis features Solvita as the cornerstone biology test for CO2 evolution combined with a suite of physical and chemical parameters useful to growers.
