Preplant applications of potassium azide (KN3) to pine nursery beds were evaluated for effect on the soil microflora and on soil enzyme activity where either plastic-sealing or water-sealing techniques were used. Two weeks after incorporation of azide (0–224 kg/ha), soil samplings revealed reduced populations of bacteria and fungi and a corresponding decline in invertase and amylase activities. These effects were proportionate to the amount of azide used and were more pronounced in plastic-sealed plots. Phosphatase activity was little affected. Five weeks after azide application, bacterial populations were higher in treated plots than in controls. Greater numbers of bacteria were recorded from plastic-sealed plots and highest populations coincided with plots receiving the highest rates of azide, regardless of the sealing technique. Fungal populations at this sampling were generally less in treated plots than in the controls, but were higher under plastic seal. At this time, changes in invertase and amylase activities did not correspond to increased microbial numbers. Sixteen weeks after applications of KN3, bacterial populations in treated plots did not differ significantly from controls, but remained higher in plastic-sealed than water-sealed plots. Fungal populations under plastic seal had changed little and remained significantly lower in treated water-sealed plots than in controls. The earlier recorded reduction in invertase and amylase activities was still evident at the final sampling.

Sodium And Potassium

The spectra of sodium and potassium azide crystals that had been coloured by irradiation with both ultra-violet and X-ray radiation for varying periods at liquid-nitrogen temperature have been recorded. From these results and from measurements of the rate of increase of intensity of the various absorption bands with time, together with the changes observed on raising the temperature, the nature and mechanism of formation of some of the centres are deduced. The different behaviour of the sodium and potassium salts under irradiation and the different effects produced by the two types of irradiation, particularly with the sodium salt, are discussed.
