Przestrzenne zróżnicowanie właściwości gleb uprawnych sąsiadujących z zadrzewieniami złożonymi z robinii akacjowej (Robinia pseudoacacia) i olszy czarnej (Alnus glutinosa)
AbstractThe aim of this study was to determine the effect of shelterbelts composed of black locust and black alder trees on the spatial diversity of chemical, physical, biological, and micromorphological properties of adjacent arable soils. The research was also aimed to determine the general status of quality and fertility of agricultural used soils in context of the distance from the shelterbelts composed of locust and alder. The study was conducted on study plots situated on arable fields, adjacent to shelterbelts. Two of them were located in the area Proszowice Plateau near the shelterbelts, consisting of plantings of black locust. The other two study plots were situated in the Vistula Lowland, in the neighborhood of alder tree linear plantings. For each study area was designated rectangle measuring 20 m x 24 m, adjacent narrow side to the plantings. The area was divided into 60 microplots within 12 zones with a width of 2 m in growing distance from shelterbelts. Soil samples were collected from all microplots from a depth of 0-25 cm. The results have been elaborated using statistical and geostatistical analysis. In order to determine the effect of distance from the shelterbelt on various properties of soils significance of differences between the properties of the soils of each zone was determined using the Kruskal-Wallis test. Spearman’s rank correlation coefficients was calculated as well. It was used global and local Moran’s index in aim to level of spatial autocorrelation determination. Correlation Moran’s index was used as well as Sperman’s correlation index to determine spatial dependence of distance from the shelterbelt on soil properties. Shelterbelts constructed of black locust and black alder contributed to the diversification properties of soils in agricultural fields located in their neighborhood. Cultivated fields lying near woodlots characterized, within the study plots, significant variability of soil properties, which should be taken into consideration during the planning field management. Variability of soil properties of arable land located in the vicinity of trees was various. The greatest variability exhibited microbiological composition and properties of micromorphological and the smallest hydrophysical properties of the soil. Organic carbon content was growing with lower distance from trees on each of studied plots. This fact should be explained on the base of a high carbon input of litterfall, that is the greater the closer to the trees. Alder and locust are counted to nitrogen fixing trees, so similar set of nitrogen content growing with decrease of distance from shelterbelts, was stated on most part of study plots. Litterfall, that contained a high content of basic elements like calcium and magnesium, had a big influence on the soil properties. It was a reason of higher pH values and a high saturation of base cations in sorption complex of soils adjacent to alder shelterbelt. A big amount of organic matter coming from trees leads to low mature of humic acids in soils, what was proofed on the base of spectral and chemical ratios. Air-water properties of studied soils were low diversified, except solid phase density, that was the smallest in soils situated in the direct neighborhood of trees. That is a proof of better quality soils situated in so called the ecotone zone. In the soils closer to shelterbelt a higher amount of crumb and channel structure types were determined, what can be connected with a higher activity of soil mesophauna.
