This test method is a procedure for the analysis of Total Kjeldahl Nitrogen (TKN), a key parameter used to determine the organic nitrogen and ammonia content in samples such as wastewater, soils, and agricultural products. The test sample is first filtered, then proceeds with the analysis of TKN.
This test method is a procedure for the analysis of Total Kjeldahl Nitrogen (TKN), a key parameter used to determine the organic nitrogen and ammonia content in samples such as wastewater, soils, and agricultural products.
This test method is a calculation method utilizing the conductivity of manure samples to determine the concentration of salts found within manure.
This test method is a calculation method utilizing the moisture of manure samples to determine the amount of solids found within the manure.
This test method is a calculation to determine organic nitrogen value from the crude protein/nitrogen and ammonium nitrogen values of manure samples.
This test method is a standardized method for determining moisture content in forage samples, important for accurate dry matter determination.
This test method is a validated procedure for the quantitative analysis of multiple metals and elements using Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). This method enables accurate determination of both essential nutrients and potential contaminants in complex biological samples. This test method quantifies calcium, copper, iron, magnesium, manganese, phosphorus, phosphorus (as P2O5), potassium, potassium… Continue reading Minerals [Manure]
This test method is a gravimetric and titrimetric procedure used to quantify the calcium carbonate (CaCO₃) content in samples such as limestone, feed supplements, and pharmaceuticals. The method measures the amount of carbonate by reacting the sample with acid and quantifying the calcium present, providing an estimate of the CaCO₃ concentration.
This test method is a classic analytical technique used to determine ammonia nitrogen (NH₃-N) in manure samples. It involves alkalizing the sample to convert ammonium ions to ammonia gas, which is then distilled, captured in an acid solution, and quantified by titration. This method measures the concentration of ammonia as nitrogen and is widely used… Continue reading Ammonium Nitrogen [Manure]
This test method is a semi-quantitative test used to detect and characterize specific groups of bacteria in water, soil, and biofilm samples. It is commonly used to identify the presence and activity of bacteria such as iron-related bacteria (IRB), sulfate-reducing bacteria (SRB), slime-forming bacteria, and others involved in biofouling, corrosion, or water quality issues.
