LABORATORY way to assess the ability of soil nitrification

摘要

A laboratory method of evaluating the nitrification capacity of soil comprising soil composting and definition of nitrates accumulated in the soil due to the decomposition of organic compounds, characterized in that, in order to increase productivity and simplify the evaluation of nitrification capacity, composting the soil samples is carried out for two weeks in vitro, in the temperature range 18-22 ° C and higher in vessels drawn into the bottom of the grid, with maintaining constant the full field capacity (PPV) daily E waterings with the free gravitational outflow of moisture and of nitrification capacity is judged by the difference between the final and initial concentration of nitrates in the soil sample.
