Field trial is an important data in fertilizer registration. According to the registration requirements and customer’s need, we will recommend reasonable crops and arrange field trial for you. We ensure that every report provided is true and valid. We recommend suitable crops and categories for you to expand the application range of products and increase the competitiveness in the market.

According to the requirements of the examination and approval department, the manufacture may carry out the fertilizer field trial by himself or entrust the relevant unit to carry out the test. The manufacturer and the testing unit shall bear legal responsibility for the authenticity.

The applicant shall carry out standardized field trials in China according to relevant technical requirements, and submit test reports of at least 2 trials each crop in one year in different regions or at least 2 years in the same region. Fertilizer field trials should objectively and accurately reflect the application efficacy trials of the tested products, with certain test sites, scientific test designs and standardized field operations, and be presided over and signed by agronomist. 

Soil regulator (including soil microbial inoculant for bioremediation) test should be aimed at the soil obstacle factor to choose typical 2 locations, and submit the successive 3 years (including) test results, the efficacy trials of improving acid soil should be carried out in typical acid soil in South China, The efficacy trials of improving saline alkali soil should be carried out in the typical saline alkali soil in North China. 

Field trials of Agro-forestry absorbent polymer should be carried out in typical arid areas. besides on yield increase, indexes that can reflect the effect of Agro-forestry absorbent polymer on soil water-holding capacity should be set up for the evaluation of test results, including at least field water holding capacity, wilting coefficient, saturated water conductivity, etc.

The results of two (points) composting or composting tests of Organic matter-decomposing inoculant shall be submitted, herein Organic matter-decomposing inoculant is specially dedicated for organic material.
