The aim of the first part of this study was: 1) to determine the full species composition of the nematodes occurring in the two crops (younger and older), which would at the same time permit of obtaining a knowledge of the variety of ecological forms of these nematodes and 2) to compare the intensity of occurrence of species in the upper parts of the alfalfa plants, in roots and in the soil, that is, to assess the penetration of different species from soil to plants.}, type={Text}, title={Analysis of the occurrence of nematodes in alfalfa crops. 1, Species composition of nematodes in two alfalfa crops of diffrent age and penetration of species from soil to plants}, URL={http://rcin.org.pl/Content/70364/PDF/WA058_86174_P2840-T15_Eko-Pol-A-Nr-2.pdf}, volume={15}, number={2}, journal={Ekologia Polska.
