The aim of this study was to investigate the scale of the deficiency of the six basic micronutrients: B, Cu, Fe, Mn, Mo and Zn in the fields of wheat grown in Poland. In the years of 2010 – 2011, 357 samples of winter wheat crops were collected from fields located in the averagely intensive farms in 16 provinces of Poland. Plants were collected in the(More)
Sources of burnable material within U.S. cities are analyzed. Based on a detailed evaluation of construction practices, storage of burnable contents, building function and layout, and density of buildings in city districts, we derive urban fuel load densities in terms of land use type and geographic location. Residential building fuel loads vary regionally(More)
The aim of this study was the assessment of macronutrient (N, P, K, Ca, Mg) accumulation in wheat at the critical phases of yield shaping as well as at the full ripening stage when judged at optimal P and K fertilizer rates applied as well as at reduced levels of fertilization with these elements. Four-year-long investigation on winter wheat was carried out(More)
Pollution of soils by heavy metals is one of the most serious problems in soil protection and for the production of safe and healthy food. In this context nickel (Ni) still remains one of the most harmful elements among heavy metals. The aim of this investigation was to quantify the effect of liming on the soil-plant transfer of Ni. In a pot experiment(More)
The aim of the study carried out under field conditions was to evaluate the effect of differentiated phosphorus and potassium fertilization level on nutritional status of winter wheat at stem elongation (BBCH 31) and flowering (BBCH 65) development stages as well as on macronutrient contents in yield obtained (grain and straw). The research was conducted in(More)
The aim of this study was to evaluate the effects of cover type (control, agro-textile or perforated plastic film) and harvest date (60 or 75 days after planting and at full physiological maturity) on the yield, quality and cost-effectiveness of early harvest potato cultivation. The study was conducted in the years 2008–2011, at the Gorzyń(More)

Research was carried out in the years 2008-2010 on the objects of stationary experiment established in 2000 at the Research Station Brody Poznań University of Life Sciences. Hortenso variety of winter triticale was cultivated in the conditions of one-factor experiment. The factor investigated was a differential level of mineral fertilization with phosphorus(More)
