Podstaw\u0105 okre\u015blenia gatunku gleby jest jej sk\u0142ad granulometryczny, czyli udzia\u0142 frakcji mechanicznych o okre\u015blonej wielko\u015bci cz\u0105stek. Cecha ta ma istotne znaczenie dla wielu fizycznych i chemicznych w\u0142a\u015bciwo\u015bci gleb, w tym w\u0142a\u015bciwo\u015bci retencyjnych, naturalnej zawarto\u015bci zanieczyszcze\u0144, odporno\u015bci na zmiany odczynu, oraz pojemno\u015bci sorpcyjnej gleb. Sk\u0142ad granulometryczny wp\u0142ywa r\u00f3wnie\u017c bezpo\u015brednio na procesy migracji zanieczyszcze\u0144 w glebie i ich biodost\u0119pno\u015b\u0107. Reprezentacja gatunk\u00f3w gleb w punktach pomiarowych jest charakterystyczna dla pokrywy glebowej kraju.<\/p>
