Differentiation of habitat conditions results in the development of areas of ryegrass grasslands of significant floristic variation and provides a basis for the distinction of lower phytosociological units. The paper contains a floristic characteristic of Arrhenatheretum elatioris syntaxons regarding their habitats. The aim of the study was a detailed characteristic of habitats including their phytosociological...
The objective of this study was to determine the effect of different production systems on contents of 29 major and trace elements in cow’s hair. The experimental material consisted of 30 cows of Polish Holstein-Friesian (HF) breed, from one dairy organic farm (15 cows) and one dairy conventional farm (15 cows). All the farms were located in one climatic zone and under similar soil conditions. In...
The study was carried out in the years 2010-2013 on drained, unused meadows situated on organic soils (wet and humid) in central Poland. The paper presents the changes and transformations of habitats and meadow communities that have taken place on these meadows due to reduced anthropopressure. Analysed post-bog meadows were formed by reclamation and drainage of lowland bogs. In the early 90s of the...
Research of the identification and determination of alkaloid contents in the aboveground parts of Phalaris arundinacea (Poaceae) during various periods of the vegetation season was conducted. Analyses were performed using an apparatus system by Hewlett-Packard (USA), consisting of a gas chromatograph model 589011 and a mass detector model 5971 A. Analyses were conducted at the laboratory of the phytochemistry...
Studies were carried out in the years 2013-2015 in a private farm in Kąty (Podlaskie Province) specialising in beef cattle breeding.

In two subsequent years (2014 and 2015) feeding experiment was performed on bull calves of Limousine race having...
Studies were carried out in a field experiment in the years 2009-2012 on a permanent productive meadow situated on peatmuck soil of the Biebrza Experimental Farm. The aim was to identify the effect of various types and intensities of fertilisation (with cattle manure and liquid manure) on botanical composition of the sward and the content of mineral nitrogen forms in soil. Mineral nitrogen was applied...
Described studies were performed in a long-term irrigated meadow experiment at varied fertilisation. The aim of the study was to assess the effectiveness of meadow renovation in terms of yielding, botanical composition of meadow sward and its protein content in relation to diverse fertilisation. Seven variants were compared including five fertilised with mineral fertilisers at a rate of 60, 120, 180,...
Productive effects and potassium and magnesium cycling in relation to the ways of fertilisation of permanent meadow on peat-muck soil were tested in field experiment in the years 2006-2009. Due to progressing soil mineralization and nitrogen release, fertilisation with only phosphorus and potassium (P-30 and K-60 kg·ha-1) was applied at the first level of fertilisation. Complete fertilisation (P-30,...
The aim of this study was to analyse the effect of different ways of mineral fertilisation (0, K, PK, NPK) on yielding, botanical composition and utility value of sward and biological values of twice mown meadows on peat-muck soil. The paper contains final results of 50-year-long cycle of studies in experiment established in 1957 in Experimental Station in Biebrza. Water conditions of soil underwent...
Studies were carried out in a long-term experiment at different fertilisation. The aim was to assess the effects of renovation in terms of yielding, botanical composition and the content of proteins and soluble carbohydrates in meadow sward at different fertilisation. Five experimental plots were fertilised with mineral fertilisers at a rate of 60, 120, 180, 180bis and 240 kg N·ha-1, respectively...
The aim of the study to evaluate selected methods of permanent grassland renovation under different soil-climatic conditions in north-eastern Poland. Studies are carried out in three farms: in Dymnik (Rychliki commune, Warmińsko-Mazurskie Province), in Kąty Milewskie (Jasionówka commune, Podlaskie Province) and in Kodeń (Kodeń commune, Lubelskie Province) specialized in beef cattle breeding with bulk...
Studies were carried out in plot experiment in the years 2006-2008 on permanent productive meadow on peat-much soil in the Biebrza Experimental Farm. Their aim was to demonstrate the effect of various types and intensity of fertilisation (including manure and liquid manure) on meadow yielding, soil pH and the content of zinc in soil and in meadow sward. The following levels of mineral fertilisation...
The study took place between years 2009-2011 in Falenty, Mazovian Voivodeship, as a part of a long-term scientific experiment, began in 1987, using the randomised block method. All blocks were irrigated until 2008. In 2009 each block was divided into two areas: irrigated and non-irrigated. The study involved four levels of inorganic nitrogen fertiliser and two levels of mixed organic and inorganic...
Badania, w warunkach wieloletniego doświadczenia ścisłego, były prowadzone metodą losowanych bloków, w czterech powtórzeniach, na zdrenowanej łące trwałej położonej na glebie mineralnej w Falentach. Celem pracy było rozpoznanie obiegu magnezu i jego bilanse, w warunkach zróżnicowanego nawożenia, łąki nawadnianej oraz bez nawodnień. Obiektami badawczymi były cztery poziomy nawożenia mineralnego (N/60,...
Badania prowadzono na doświadczeniu łanowym w latach 2006-2008 w ZD Biebrza na wieloletniej łące produkcyjnej, na glebie torfowo-murszowej. Celem badań było rozpoznanie wpływu różnych poziomów i rodzajów nawożenia (w tym obornika i gnojowicy bydlęcej) na plonowanie łąki, zawartość magnezu w runi, glebie i wodzie gruntowej oraz jego bilanse. Ze względu na postępującą mineralizację tej gleby i uwalnianie...
Badania prowadzono w latach 2009-2012, metodą wywiadu bezpośredniego w wybranych 22 gospodarstwach rolnych województwa wielkopolskiego i zachodniopomorskiego, zlokalizowanych na terenie powiatów pilskiego, czarnkowskotrzcianeckiego oraz wałeckiego prowadzących produkcję w systemie zrównoważonym oraz ekologicznym.
