ESTIMATION OF WHEAT STRAW AND RAPESEED USEFULNESS FOR WHEAT FERTILISATION IN ARABLE FARMING

The aim of the research was the estimation of wheat and rapeseed straw usefulness for fertilising plants in arable farming. The subject matter of the study was the analysis of the influence of soil fertilisation with wheat and rapeseed straw on the yield and changes in the content of phosphorus, potassium, calcium and magnesium in winter wheat grain cultivars: Finezja and Ludwig. The static field experiment was conducted at Agricultural Experiment Station, Grabow, Institute of Soil Science and Plant Cultivation – State Research Institute (51°21′ N, 21°40′ E) in the years 2008–2010 on Haplic Luvisol. The effect of fertilisation with wheat and rapeseed straw did not have a significant effect on grain yield of winter wheat cultivars ‘Finezja’ and ‘Ludwig’. The introduction of complementary nitrogen fertilisation caused an increase in grain yield of wheat cultivar Ludwig. Organic fertilisation with wheat and rapeseed straw as well as complementary nitrogen fertilisation did not significantly differentiate the content of phosphorus, potassium, calcium and magnesium in winter wheat grain cultivars ‘Finezja’ and ‘Ludwig’.

Multicomponent mineral fertilizers vs. soil abundance after sugar beet cultivation

The aim of the research was to analyze the impact on changes in the content of macronutrients in the soil after the cultivation of sugar beet, resulting from the application of mineral multicomponent fertilizers manufactured by Polish and foreign producers. The effect related to fertilizers of Belarusian, Russian and Polish production applied in different doses was also analyzed. The experiment was carried out in 2014–2017 in Lipnik. The experimental plant was sugar beet of NATURA KWS cv. Thestudies compared two factors: 1st factor – 3 multicomponent mineral fertilizers: Belarusian (A), Russian (B) and Polish, i.e. Polifoska (C); 2nd factor – 3 doses of fertilization (minimum, optimum, maximum, amounting to 2.0 4.0 and 6.0 dt per hectare, respectively). Fertilization with multicomponent fertilizers produced by Belarusian, Russian and Polish manufacturers did not change the pH of soil from experiment. In the experiment carried out, there was no diversified effect of multicomponent fertilizers of Belarusian, Russian and Polish origin regarding changes in the content of available phosphorus and available potassium in the soil, as well as exchangeable magnesium. The use of different doses of multicomponent fertilizers resulted in a significant increase in the content of available phosphorus and potassium in the soil.

ASSESSMENT OF THE USE FOR FERTILISATION PURPOSES INCINERATION ASH PELLETS USING GASIFICATION BURNER LESTER

The use of biomass in system energetics for the purpose of increasing the share of renewable energy sources in the overall energy mix by biomass and coal co-combustion is not an optimal solution in the light of previous experience in Poland. It is appropriate to develop local biomass market for energy purposes as a basis for future distributed energy generation based on biomass. This solution facilitates the use of ash from biomass combustion for plant fertilisation. The present paper concerns the assessment of the use of ash from combustion of pellets in an innovative gasifying pellet burner – LESTER type, for soil fertilisation. The paper presents the analysis of the content of macroand microelements in ash against the chemical composition of pellets in relation to permissible contents in fertilisers. The content of phosphorus, potassium, calcium and magnesium in bottom and fly ash from combustion of wood pellet and rye straw in LESTER gasifying burner validates the use of this material for soil fertilisation purposes. However, due to low nitrogen content – comparable to that found in soil, the material is not to be considered as fertiliser supplying this macroelement to soil. The analysed bottom ash used for fertilisation meets the conditions set out in the Regulation of the Minister of Environment of 9 September 2002. However, fly ash should be used with considerable caution due to high content of iron, zinc and nickel. The yield of bottom ash is several times higher than that of fly ash, therefore, the possibility of its use in a form of mixtures in adequate proportions should be considered.

ANALYSIS OF THE CONTENT OF MINERAL COMPONENTS IN GRAIN OF WINTER SPELT (TRITICUM AESTIVUM SSP SPELLED L.) DEPENDING ON: TILLAGE SYSTEM, FERTILIZATION NITROGEN AND VARIETY

The aim of the study was the assessment of the influence of two cultivation systems and doses of nitrogen fertilization on the content of mineral elements (nitrogen, phosphorus, potassium, calcium, magnesium and manganese) in grain of three varieties of winter spelt (Triticum asetivum ssp spelta L.). The field experiment was conducted in the period 2009–2011 in the Agricultural Experimental Station in Lipnik (53o42’N, 14o97’S), administered by West Pomeranian University of Technology in Szczecin. The experiment was set up on brown earth composed of loamy sands of slightly acidic pH – 6.5 in 1 mol KCl. The material for the analysis was the grain of winter spelt. Three factors were compared in the analysis: two methods of soil cultivation – simplified and conventional – (I factor), four doses of nitrogen: 0, 50, 100 and 150 kg N·ha-1 (II factor) and three varieties: Franckenkorn, Oberkulmer Rotkorn, STH 12 (III factor). The grain of spelt (Triticum spelta L.) cultivated according to the simplified system was marked by increased content of mineral elements, yet it varied significantly only for two the elements: potas-

Effects of Limestone, Ash from Biomass and Compost Use on Chemical Properties of Soil

Abstract The aim of this research was to assess the use of biomass ash for fertilisation of mineral soil. The study involves the analysis of the effects of biomass ash applied to soil on the changes of pH and the content of the available forms of phosphorus, potassium and magnesium as well as on total content of zinc, copper, manganese, nickel, cadmium and lead. The field experiment was conducted in 2013 in Duninowo near Ustka. In experiment grown two plants spring: Spring barley - var. Sebastian, and wheat - var. Bombona. The use of ash from biomass and Biotop compost as fertilisers did not result in any significant changes of soilpH. The use of ash from biomass and Biotop compost caused a significant increase in the contents of available phosphorus, potassium and magnesium in soil. The threshold values of the analysed trace elements in soil, as specified by the Regulation of the Minister of Environment, were not exceeded in any of the fertilising variants in the experiment.

WPŁYW STOSOWANIA WAPNA, POPIOŁU Z BIOMASY I KOMPOSTU ORAZ PREPARATU EM NA PLONOWANIE I KOMPONENTY PLONU PSZENICY

Field experiment was conducted in 2013 in Duninowo (54 o 539’ N, 16 o 830’ E). The experimental factors were: I. factor - 6 variants of fertilization, and II. - two level of EM preparations. The aim of this study was to evaluate the impact of ash from biomass by comparing its effect with the calcium fertilizer and compost BIOTOPE in conjunction with the preparation of microbiological Effective Microorganisms (EM). The impact of ash from biomass introduced into the soil on yield and yield structure and physiological parameters of spring wheat was analyzed No significant impact of the various variants of fertilizer application on the yielding

Changes of Calcium and Magnesium in the Beddings Made From Sewage Sludge and Fluidal Ash From Hard Coal and in Festulolium Braunii Grass

Abstract Based on the results of a three-year study with Festulolium braunii, Felopa variety, the influence of factors introduced in the experiment on the calcium and magnesium content and ratios of ions in the soil and grass was observed. The use of sewage sludge fertilization together with straw significantly increased the total content of calcium and magnesium in the soil beddings and lower surfaces of the ash in the coal beddings. The introduction of the preparation EM-1 was a factor in lowering the overall content and exchangeable forms of calcium and magnesium in the beddings. Adding to the bedding of sewage sludge caused a reduction in calcium and increases magnesium content in grass
