2008-10-5 · Nitrogen Soil N exists both in mineral (inorganic) forms, available for plant uptake, and in complex organic forms that are not readily available. The most common analytical approach to determine mineral N concentration is potassium chloride extraction. There are two mineral N forms, NO3-N and ammonium-nitrogen (NH4-N); the NO3-N form usually predominates, and often is the only form reported. NO3-N exists only in a soluble form and is easily extracted from soil, and therefore the soil test result unambiguously describes soil

Abstract Eukaryotic cells were extracted from mineral soil by shaking in 50 mM Tris buffer, pH 7.5. This extracted a greater biovolume of cells than shaking in a range of surfactants, blending or sonication. An aliquot of soil suspension was incubated with iodonitrotetrazolium (INT) and then loaded onto a linear density gradient prepared from Percoll and phosphate buffer.
