abstract:
In field experiments conducted in the valley of the River Bystrzyca the influence of the application of treated municipal sewage waste on some of the physicochemical properties of peat-muck soil was evaluated. The waste was administered in three doses: a – 0 (control), b – single (S1) and double (S2) dose. The plants tested were poplar, purple willow and flagellum willow, maize, hemp, spring rape and mixtures of grasses. The single dose for poplar, purple willow and flegellum willow was 900 mm, for maize, hemp and mixture of grasses – 600 mm and for spring rape – 400 mm. The dose S2 was doubled. Watering the peat-muck soil with treated municipal sewage waste did not cause any considerable changes of its reaction. On the other hand it reduced the value of hydrolytic acidity. It improved the content of Ca2+, Mg2+ and Na+. It enhanced its properties through the increase of the content of the alkaline cations sums and the complete sorptive capacity.
