W próbach gleby pobranych z trzech warstw w różnych systemach uprawy roli oznaczono skład gatunkowy, ilość i rozmieszczenie nasion chwastów. Ogółem w badanych warstwach gleby oznaczono nasiona 22 gatunków chwastów. Na obiektach z uprawą bezpłużną i siewem bezpośrednim stwierdzono występowanie nasion chwastów nie notowanych w uprawie płużnej. Zarówno w systemach uprawy, jak i w poszczególnych warstwach...
The present research was carried out over 1997-2000 on good rye (Agricultural Experiment Station Lipnik in the vicinity of Stargard Szczeciński) and good wheat (Agricultural Experiment Station Ostoja in the vicinity of Szczecin) soil suitability complexes in a static crop-rotation experiment, which compared the effect of soil cultivation systems: A - plough, B - ploughless, C direct sowing (Lipnik...
The research included a static crop-rotation field experiment set up in 1993: sugar beet winter wheat faba bean winter barley + stubble intercrop and covered the effect of three soil cultivation systems: A ploughing cultivation, B ploughless cultivation, C direct sowing on selected chemical properties of soil sampled from three soil profile layers: 0 10 cm, 10 20 cm and 20 30 cm...
The 1990-1992 research investigated the impact of foliar fertilisation on the chemical composition of potato leaves, stems, stolons and tubers over flowering. It was observed that neither foliar fertilisation with a 6% of aqueous solution of carbamide and a multi-component fertiliser (Agrosol - K) nor solid fertilisation caused significant differences in the contents of N, P, K, Ca, Mg in respective...
The research investigated the effect of three tillage methods: A - ploughing, B ploughless cultivation and C - direct drilling, on the distribution and dry weight of plant roots in sandy loam soil. More abundant roots were observed in winter wheat in direct-drilling objects and in spring barley exposed to ploughing. Dry matter of roots was higher in the 0-10 cm than in the 10-20 and 20-30 cm layers...
