The impact of a bottom sediment on the reaction and the content of exchangeable aluminium in a soil

Abstrakt

The aim of the study was to determine the effect of bottom sediment on the pH and content of available forms of P, K, Mg and aluminium exchangeable in the soil and on the yield of oats.The research was carried out in the Podlasie voivodship on very light soil. The material for the tests were samples of bottom sediment. In the experiment a bottom sediment from the breeding pond and soil was used. In the sediment bottom sediment sam-ple, the following parameters were determined: pH, heavy metal content (lead, cadmium, zinc, copper), as well as the content of aluminum, phosphorus, potassium and magnesium. The reaction of the bottom sediment was also determined. In soil samples, the content of exchangeable aluminium, available forms of phospho-rus, potassium, magnesium was determined and the soil reaction was determined. The obtained results confirmed the influence of bottom sedi-ment on reducing the content of exchangeable aluminium in the soil. The analyzes show that the soil after application of bottom sediment contained significantly less exchangeable aluminium. The sludge also influenced the increase of soil pH and the incre-ase of magnesium content in the soil. There was no influence of the use of bottom sediment on the content of available phospho-rus and potassium in the soil and on oat yield.
