Montia linearis is a vascular plant originating from western North America. The expansion of this species has been observed for several decades. For the first time M. linearis was found in Europe in 1989. Further six populations were documented by 2004 within the continent: three in Poland, two in Denmark and one in Hungary. Apart from discovering a new population of M. linearis, we confirmed two...
The weather conditions in winter 2011/2012 in Poland caused severe frost killing of winter crops (in most areas up to 90%) requiring spring resowing. This brought about a considerable impact of chemical plant protection. The paper presents results from two farms, belonging to a State Treasury company, with intensive agricultural production, located in the Wielkopolska voivodship. The number of plant...
In an agricultural landscape small midfield ponds fulfill biocenotic and physiocenotic functions. A variety of species settle in areas of midfield ponds. The aim of our studies was to determine whether the occurrence of aquatic and marsh species in the studied bodies of water is a random effect or a result of spatial autocorrelation. On the basis of conclusions from ESDA, the hypothesis of spatial...
Significant attention was paid in all developed countries to the agriculture until the seventies of the last century. It was due to the food deficiency in the post-war period. The period of the intensive agriculture production in the former Czechoslovakia lasted longer, due to the necessity of the high self-sufficiency in food feed and raw materials, produced in the agriculture in the closed system...
Catchment of the Mielnica Stream is situated in Trzebnica Mills area, covered with loess soils and under an intensive agricultural use, Bathometrical and hydrometrical measurements were taken in the hydrological years 1982/83-1993/94. Daily and periodical masses of a suspended load carried out through the hydrometrical cross-section, flow and unit run-off rates were analysed. The weight of total measured...
Umiejscowienie płodozmianów w systemach produkcji roślinnej wymaga ustalenia nazewnictwa tych systemów, a następnie kryteriów i granic specjalizacji. Wyróżniono trzy systemy: intensywny, średniointensywny i ekstensywny. Podstawą charakterystyki tych systemów były dane z literatury i technologie produkcji poszczególnych ziemiopłodów: zalecane (IUNG) - intensywna i standardowa oraz powszechnie stosowana...
