Abstract
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 s lice of soil (0.9 cm thick) into 45 subsamples, which were analyzed in dividually. After analysis, the data were presented in graphical forma t to show the nutrient concentrations in the zone. The method was rela tively easy to carry out using equipment that could be easily construc ted. The precision of the procedure was high as indicated by the low v ariability between replicates.
