摘要:

A procedure was developed to sample and analyze levels of ammonium and urea as well as pH in the soil within the immediate zone of a single urea fertilizer granule. The method involved sectioning a 2 x 3.6 cm slice of soil (0.9 cm thick) into 45 subsamples, which were analyzed individually. After analysis, the data were presented in graphical format to show the nutrient concentrations in the zone. The method was relatively easy to carry out using equipment that could be easily constructed. The precision of the procedure was high as indicated by the low variability between replicates.
