In the sequence of soil composed of black earths, deluvial soils, organic soils covered with a thin layer of mineral-organic deposit and moorsh soils, soil texture, bulk density, content of organic carbon and organic matter, total porosity, total and readily available water as well as resources of organic matter and water in 0-25 cm and 0-100 cm layers of the soil profile were studied. A catenal variabilities...
The paper analyzes the advantages and disadvantages of the most commonly used groups of models of soil moisture and plant water stress based on satellite thermal imagery. We present a simple proof of linking NDTI and CWSI indicators with plants water stress and quantitative justification for the shape of the points cloud on the chart Ts-NDVI.
The paper presents the results of the study connected with determining the contents of total organic carbon (TOC), total nitrogen (TN), available phosphorus (PE-R), sulphate sulphur (S-SO4 2-), and the activity of acid phosphatase (AcP) and arylsulphatase (ARS) in Haplic Luvisol (LVh) fertilised with varied farmyard manure (FYM) doses (0, 20, 40, 60, 80 t ha-1) and nitrogen in the form of ammonium...
Different soil texture classification systems are used in Poland. The system most widely used in agriculture is named after Polish Soil Science Society (PSSS) and is described in the soil classification norm BN-78/9180-11 (BN1978 standard). The last edition of soil classification system and soil texture classes published by PSSS in 2008 (PSSS 2008 classification) is different from BN1978 standard...
Performing a primary analysis, such as principal component analysis (PCA) may increase accuracy and reliability of developed pedotransfer functions (PTFs). This study focuses on the usefulness of the soil penetration resistance (PR) and principal components (PCs) as new inputs along with the others to develop the PTFs for estimating the soil water retention curve (SWRC) using a multi-objective group...
At the turn of the 19th and 20th centuries large peatland areas of the Stołowe Mountains were drained for the forestry use. The aim of the study was to assess the real impact of the natural (climate) and anthropogenic (forestry drainage) factors on the actual nitrogen mineralization in the shallow organic soils in the Stołowe Mountains National Park (SMNP). For the needs of the study, two research...
The study consisted in assessing the impact of the cement industry on the selected physicochemical properties and total and bioavailable content of heavy metals in soils located in the vicinity of the factory. The sampling points were located in the four transects to the east, west, north and south of the plant, at an increasing distance of 0 - 250 - 500 - 1500 and 2000 m. The soil samples were collected...
This overview article presents major forms of reclamation and development of external and internal spoil tips, which are formed during brown coal mining and from bottom ash dumped near open-pit mines and power stations. In the late 1970s, a new form of agricultural and forest recultivation was developed – the PAN model. According to the concept, crops and forest-forming plant species should be introduced...
The studies involved determining the influence of Cr(III) and Cr(VI), as well as compost, zeolite and calcium oxide on the content of selected macronutrients and trace elements in soil in which oats were grown. An increase in the content of total chromium, manganese, zinc and nickel took place along with increasing contamination with Cr(III) and Cr(VI). In pots with Cr(VI), the addition of compost...
In the present work, we aimed to study the effect of quantitative changes of micronutrients (Cu, Zn, Mn) in soil and plants caused by wood ash applied into the soil in increasing doses. A pot experiment with medium textured soil, white mustard as a test plant and six amendment treatments (doses of wood ash: 0, 1, 5, 10, 20, 30 Mg·ha-1) was performed. Total contents of Cu, Zn and Mn were determined...
In Indonesia, agricultural land for oil palm plantation is mostly placed on slope areas. Erosion carries down surface soil layers which are generally fertile and rich in organic matter and nutrients, causing the loss of plant nutrients. Cover crops provide protection against the destruction of soil aggregates by rain and runoff. This research aims to study the effectiveness of vegetation as soil conservation...
This paper looks into the impact of free grazing by sheep and horses on the chemical and biological properties of soils in the partial protection zone of the Roztocze National Park. The study sampled three different types of pastureland in the area: pastures for sheep, horses and for combined grazing by sheep and horses. Compared to an ungrazed reference pasture, free grazing significantly stimulated...
Studies have been undertaken which assess the possibility of neutralising the effect of zinc on the contents of: organic carbon, total nitrogen, available forms of: phosphorus, potassium and magnesium in soil by applying neutralising substances – compost, bentonite and zeolite. In the series without an addition of neutralising substances, increasing zinc soil contamination resulted in an increase...
Fluvial sediments accumulated in the bottoms of river valleys downstream from large cities are characterised by higher levels of heavy metal content, which poses a threat to the environment and humans. This study presents a comprehensive assessment of the degree of pollution of four alluvial sediment profiles (80 samples), collected from the bottom of the Bystrzyca river valley downstream from Lublin,...
The subject of this study was the humus horizons in the salt-affected soils of Natura 2000 (Ciechocinek, Poland). In the adequately prepared soil, there were determined: pH in CaCl2, total organic carbon (TOC), exchangeable cations (Ca2+, Mg2+, Na+, K+), salinity (EC1:5), the content of total (TP) and available phosphorus (AP), the activity of alkaline (AlP) and acid (AcP) phosphatases. TOC affected...
The study assessed the influence of the distance between a reflectance sensor and soil samples with various roughness states (R1– the lowest, R2 – the medium, R3 – the highest roughness state) on their spectra level, under laboratory condition. Studied soil samples were illuminated at three light source zenith angles (θs equal to 20°, 40°, 60°) and observed by the sensor to the nadir, from various...
In the highlands of the Ukrainian Carpathians, brown soil formation process is supplemented by turf, which significantly affects the soil properties and composition formation – this way unique shallow, rubble, highly acidic, base unsaturated, mountain-meadow brown soils with high Corg content (Dystric Cambisols) are formed. Irrational and haphazard farming in the valleys leads to the soil degradation...
