Phosphorus is an important life-supporting nutrient and therefore it is often applied in fertilizers. As a result, its pool in soil may increase due to the presence of various elements effectively binding P, making it unavailable to plants. Each soil exhibits many characteristics important in P cycling, with the aeration state (redox potential and moisture), pH, and the presence of N, Ca, and Fe being...
The effect of ameliorating doses of hard coal fly ash (HCFA) on chemical properties of soil and on yields and chemical composition of crops was examined based on an experiment established in 1984. At first, typical agricultural crops were grown in the experiment, but in 1992 the field was turned into permanent grassland. The current study took place twenty-nine years after hard coal fly ash had been...
This study was based in the morainic zone and zone of ice-dammed lake origin of a young-glacial landscape as well as in riverine and delta landscapes, involving the sorptive properties of mucky soils and variously silted peat-muck soils which were termed upper silted organic soils. These soils had a low share of exchangeable potassium and magnesium in relation to the total content of these elements...
Taking advantage of the long term field stationary experiments in Skierniewice started at 1922 based on fixed mono-fertilization, the mobility of the exchangeable cations Ca, Mg, K, Na was studied for the whole soil profile up at a depth of 100 cm. Mobility was studied using an electrodialysis method to remove and determine cations in the cathode solutions. Calcium proved to be most mobile element...
The purpose of this study was to determine the effect of soil properties and Cd or Pb addition on the transformations of Pb in soils and its distribution between different fractions determined according to Tessieret al. The study was carried out in model pots filled with mineral or organic soils taken from the surface soil layer. The soils showed either acidic or neutral reactions. The mineral soil...
Changes in the content of mobile phosphorus forms and their migration were studied in mineral meadow soil after application of artificial cattle urine to a number of locations in a pasture. Studies were carried out in three field experiments situated on black degraded earth in Falenty in 2004-2005. The amount of phosphorus released from soil (P-extr.) from under locations of simulated urination using...
The basic properties of soils in major physiographic units of the area were examined. The content of several heavy metals (Cu, Zn, Mn, Pb, Cd, Co) in soils and selected vascular plants were determined, also. The relationship between the content of metals in plants and the content of metals in soils was determined. The content of metals in both soils and plants had a particular order, although not...
On the basis of obtained results a de-acidifying compost effect was proved. In the subsequent years, irrespective of the applied fertilization, a declining pH value was registered but also an increasing value of soil hydrolytic acidity. The highest acidification rate occurred in the soil with the mineral treatment. During the three year period of the investigations a decline in the organic C content...
The work presents the diversification of podzols in the Babiogórski National Park, concerning their concentrations of oxalate and pyrophosphate forms of iron and aluminium depending on the altitude above the sea level and the vegetation that covers them. It was found that the effect of climatic conditions on the chemical properties of these soils is strongly modified by the soil covering vegetation...
