Testing of Humic Acid in Biofertilizers and Feeds

Humic acid is a naturally occurring mixture of organic macromolecular compounds that are widely found in nature. Biological humic acid can be sold directly as fertilizer and feed additive or made into compound fertilizer or compound fertilizer. Or extract the fulvic acid component from it to make foliar fertilizer and water-soluble fertilizer, etc., which has broad application prospects.

Lifeasible provides analytical services to our customers for the detection of humic acid-like substances in biofertilizers and organic feeds. This includes qualitative analysis of the sample to determine that the sample is a humic acid-like substance, followed by quantitative testing of the organic matter, humic acid, and bioflavonoids content of the product respectively, and grading of the humic acid-like substance according to the organic matter, humic acid and bioflavonoids content.

We provide testing services

• Humic acid test
• Fulvic acid test
• Biological humic acid full carbon content test
• Soluble humic acid content test

General steps for the determination of humic acid content in samples

Test methods we use

• We will analyze the samples qualitatively, such as structure and functional groups, and determine the sample properties by infrared spectrogram and ultraviolet spectrogram analysis. Samples with major characteristic absorption peaks in the ultraviolet and infrared absorption spectroscopy analysis are identified as humic acid-like substances.
• We use a spectroscopic method for efficient detection of fulvic acid content in biofertilizers and organic feeds to meet your different needs.
• We use the volumetric method to determine the content of soluble humic acids in biofertilizers and organic feeds with humic acids. It has the advantages of easy operation, good stability, practicality, and reliable accuracy of the test results.
• We purified the samples by alkali solubilization and acid precipitation method and performed a single-factor multilevel analysis on extraction time, extraction temperature, solid-liquid ratio, extraction reagent, and acid precipitation pH to determine the best purification conditions suitable for the desired humic acid-like substances.
• We offer services for the determination of carbon coefficients of humic acids in biofertilizers and organic feeds. The sample to be tested is first pretreated, then the sample is purified and the carbon content in the purified sample is determined by a micro computerized hydrocarbon analyzer. Finally, the carbon coefficients of the humic acid samples are calculated mathematically.

Lifeasible, as a professional biofertilizer and organic feed solution provider, can solve the problems related to the testing of biological humic acid substances, biological activity evaluation, etc., and can issue a complete humic acid test report. And the methods we provide applications to a wide range of sample types. We have been your reliable partner, please feel free to contact our staff to submit a test request.
