Phosphorus Accumulation in the Dehydrated Peat Soils of the Liwiec River Valley

Becher Marcin, Pakuła Krzysztof, Jaremko Dawid

Journal of Ecological Engineering

2020

Vol. 21, nr 5

213--220

The aim of the research was to complement the knowledge on profile distribution and accumulation of phosphorus forms in the soils changed under the influence of secondary organic matter transformation process in dehydrated peatlands. The soil research was carried out in the upper Liwiec river valley in the middle-east of Poland. In the soil material taken from the moorsh (M1, M2, M3) and peat (O) horizons of the Murshic Histosols, the physical and chemical properties were determined and the soil phosphorus fractions with different activity in the environment by sequential extraction method were separated. The profile distribution of the total phosphorus content (TP) and values of carbon/phosphorus (TC/TP) ratio were characteristic for dehydrated peat soils included in the secondary transformation process (M1>M2>M3>O). This process also increased the contribution of the available phosphorus forms (NH4Cl-P), forms bound on the surface of iron (III) and manganese (IV) oxides and hydroxides (redox-P), as well as mineral (mHCl-P) and organic (oHCl-P) forms separated by 0.5 M HCl. Significant accumulation of the phosphorus compounds in the moorsh horizons of the investigated soils can be considered as a potential threat to the natural environment of the studied area due to the risk of decomposition of the phosphorus compounds when the area will be rehydrated.

Badania nad wpływem nawadniania ściekami na zawartość Mn, Zn i Cu w glebie i roślinach przeprowadzono w glebie torfowej. Roślinami testowymi były: kukurydza, rzepak, konopie, trawy, topola i wiklina. Stwierdzono istotne zwiększenie zawartości rozpuszczalnych mikroelementów Zn i Cu w glebie po nawodnieniu ściekami, natomiast zawartość mikroelementów w roślinach testowych nie była znamiennie zróżnicowana. Charakterystyczna zmienność zawartości mikroelementów w glebie i roślinie wskazuje na przydatność tych chemiczno-rolniczych wskaźników do oceny nawadniania ściekami w agrosystemie.

An investigation on the content of Mn, Zn, and Cu in soil and plants was carried out on peat soil. Indicator plants were corn, rape, hemp, grasses, poplar and willow. It was found that in soil significant increase in content of soluble micoelements Zn and Cu in soil after irrigation with sewage water, however content of microelements in indicator plants were not significantly differentiated. Variable characteristic of content of microelements in soil and plant inicate on usefulness these agrochemical indices to evaluation of irrigation with sewage water in agrosystem.
