The present study shows the content of different potassium forms found in lessive soil and was based on a 12-year long field experiment. In this work the following conditions were used: differential N fertilization and differential irrigation (fields were either left with no water or irrigated). The soil samples were collected from three different depths that matched genotypes of lessive soil: 0-30,...
The paper outlines the analyses of chemical composition of groundwater from 13 monitoring well located in the vicinity of Lake Gopło. The measurements were performed between 2014 and 2017. We measured the concentrations of NO3-, NH4+, PO43-, Ca2+, Mg2+, K+, Na+, Cl-, HCO3-as well as electric conductivity and pH. In major analyzed samples the concentrations of the above chemical species fell in the...
The paper presents the results of the research on the effect of PRP SOL fertilization on the basic chemical properties of soil and composition of soil solution. The soil has been sampled from the level of humus of many years' experiment established on light soil using traditional fertilization (NPK) and PRP SOL fertilizer was used instead of PK fertilization. Nitrogen doses remained the same in both...
The paper discusses the contents and chemical forms of potassium in post-mining soils after 35-year-long experimental cultivation. In the experiment the post-mining dump deposits were fertilized with N, P, K, NK, NP, PK or NPK. Wheat and rape were sowed on the fields. The control field was left unfertilized. In the years 2014-2016 surface (0-30 cm) and subsurface (30-60 cm) layers of fertilized and...
The article presents the results of a study of microbial properties of soils influenced by emissions from the salt mine in Kłodawa vs salinity parameters. 15 medium-sized surface soil samples were collected from fields adjacent to the salt mine. The following parameters were measured in the samples: the content of water-soluble cations, pH, electrolytic conductivity, the content of carbon and nitrogen,...
Osadniki wód kopalnianych to na ogół czasowe budowle hydrotechniczne związane z oczyszczaniem wód dołowych z zawiesiny mineralno-organicznej. Po zakończeniu eksploatacji węgla i odcięciu sztucznego zasilania podlegają, w zależności od uwarunkowań hydrologicznych i hydrotechnicznych, osuszeniu lub wykorzystywane są jako zbiorniki wodne. Osuszone osadniki podlegają najczęściej samoczynnej rekultywacji...
The paper contains the results of the research on the content of phosphorus and its speciation in the soils formed from postmining lands after over thirty years of their reclamation. Experimental factors included two crop rotations: frumentaceousrapeseed and fodder-frumentaceous, and three fertilization levels: 0NPK, 1NPK and 2NPK. Fractioning was conducted with Hedley’s method. Total content of phosphorus...
