W pracy przedstawiono statystyczne charakterystyki wodne tj. zależność potencjał wody glebowej - wilgotnośc czarnoziemów Polski.Stwierdzono że najwieksze ilości wody użytecznej dla roślin retencjonuje warstwa powierzchniowa i podglebie czarnoziemów.Najkorzystniejsze stosunki powietrzno-wodne w czarnoziemach Polski panują w ich warstwie podpowierzchniowej , gdzie układ porów zapewnia równowage pomiedzy...
Sources of heavy metal emission; examples of heavy metal concentrations and distribution in soils; and the consequences of chemical degradation of agricultural land in Poland are disscused in this paper.
Up-to-date studies on erosion, including erosion on loessial soils, are based on the division of an actual topographic surface into three zones assumed a 'priori': top area, eroded slope area and foot-hill area as depositional area. As the main research method for the field survey the soil-levelling cross-section has been used most frequently. Although this method allowed us to introduce erosion protection...
