Dataset of nitrogen mineralization and enzyme activity in temperate forest dark brown soils under amino acid addition

Each treatment was repeated three times, for a total of 216 soil samples to be tested. Measure seven indicators including ammonium nitrogen, nitrate nitrogen, total carbon, dissolved organic carbon, soil pH, protease, and urease, and calculate three nitrogen mineralization parameters: ammonification rate, nitrification rate, and net nitrogen mineralization rate. The dataset contains raw measured data on soil physical and chemical properties, inorganic nitrogen, extracellular enzyme activity, nitrogen mineralization rate calculation results and variance analysis under different forest types and amino acid treatments, as well as correlation statistical data.

It can be used for research on organic nitrogen transformation and amino acid regulation of soil nitrogen cycling mechanisms in temperate forest dark brown soil.
