This paper presents an influence of three different magnetic fields stimulation systems for growing strawberry fruits: permanent magnetic field generated by neodymium magnets, ”high” strengths slow varying amplitudes magnetic fields generated by coreless solenoids supplied by autotransformer and low-frequency and low-amplitude sinusoidal magnetic fields generator created for this research. The system is controlled by computer and allows for an independent control of up to 10 induction coils inducing magnetic fields with amplitudes from 0.1μT to 150μT and frequencies from 0.1Hz to 100Hz. The proposed set-up was used during the growing seasons for strawberry plants stimulation. An increase in the extract level was observed in the case of the alternating magnetic field stimulation with the parameters: frequency – from 50Hz to 100Hz and amplitude – from 50μT to 100μT.

This study includes the content of water, ash and volatiles in dried herbs like Oregano, Basil and de Provance. Moreover, amounts of H, N and C, and their calorific value were measured. The content of the following elements (Al, Ba, Ca, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, P, S, Sr, Zn) in the tested herbs were established using the ICP-OES method. Basil leaves had the highest nitrogen and ash content at the level 4.5% and 15,9%. These herbs were characterized by a darker color as compared to oregano. Basil contained the richest source of Ca, K, Mg and P, while the lowest was found in herbs de Provence. The best source of Ca, K, Mg and P was basil, while their lowest amount was found in herbs de Provence (containing a mixture of different herbs), which mostly likely was the reason for the low amount of macro- and micro-components.

The paper presents findings showing the influence of amending soil with biochar and biomass ash on the germination rate of Virginia mallow. Comparative analyses examined the relationship between the applied dosage of the natural fertilizers and the effectiveness of seed germination as well as mass of the plants at the initial stage of growth. The obtained plant material was also examined for the contents of selected macro-elements (phosphorus, potassium and calcium). The study shows that biochar applied as a fertilizer, at specific dosage, may enhance germination rate of Virginia mallow seeds. Addition of biomass ash into the soil, at certain doses, significantly impacts the growth of mass in Virginia fanpetals at the initial stage of development. It has been determined that addition of biochar, or biomass ash or their mixtures into the soil alters the concentration of phosphorus, potassium and calcium in above-ground parts of the plants.

In the article the results of studies conducted regarding the thermal processing of rape straw, rye straw and willow chips applying various parameters of the pyrolysis process are presented. Samples of biomass were subject to thermal processing at various temperatures and process durations, assessing the impact of the applied conditions on physicochemical parameters of the obtained pyrolysis products. The contents of phosphorus, potassium, magnesium, carbon and nitrogen were analysed. The studies have indicated that the pyrolysis process can be used to refine biomass, among others obtained from straw and chips, in the context of using it for fertilization. Modification of the pyrolysis process parameters (temperature, time) significantly impacted the concentration of the analysed macroelements. It has been stated that the highest content of phosphorus, potassium and magnesium in biocarbon (rape straw, rye straw and willow chips) can be obtained performing pyrolysis at the temperature of 5000C for 10 minutes. A significant impact of the pyrolysis parameters – temperature and time on the total content of macroelements in the obtained biocarbon was observed. The highest contents of phosphorus, potassium and magnesium were observed in the case of biocarbon obtained at the temperature of 5000C during 10 minutes, while the temperature of 4000C and duration of 10 minutes allowed to obtain the maximum content of carbon and nitrogen.

Magnetic field may be applied as a physical factor to improve germination capacity as well as growth and development of plants. In order to investigate the influence of stimulation with magnetic field and fertilization on the yield and quality of sugar beet roots, a field experiment was carried out in 2015 and it was designed to examine three cultivars of sugar beets, two variants of magnetic stimulation applied to seeds: stimulation in the magnetic field of 40 mT, and control conditions (no stimulation), as well as two variants of mineral fertilization: optimal, based on the contents of nutrients in soil, and control conditions (no fertilization). Observation of the plants’ growth and development was conducted during the vegetation period. The examined values included yield of roots and leaves, as well as contents of heavy metals, macro- and micro-elements and sugar. The observations carried out during the experiment and following harvest showed that the applied variable factors used in the experiment, i.e. the pre-sowing stimulation with magnetic field as well as properly designed fertilization, positively affect the parameters of the plants germination, growth and development as well as the contents of sugar in the examined sugar beet roots.

The presented system describes a concept for generating slowly varying signals to stimulate biological objects with magnetic field. The system enables independent control of up to 10 induction coil and it generates changeable signal inducing magnetic fields in the range from 0.1 to 150μT and the frequencies from 0.1 to 100 Hz. The proposed system was applied to investigate the influence of magnetic fields with the aforementioned parameters on physical and chemical properties in selected types of fruits.

W pracy przedstawiono wyniki badań dotyczące kaloryczności, zawartości wody, popiołu oraz węgla, azotu i wodoru w czterech rodzajach brykietu. Materiał badawczy stanowiły brykiety ze słomy zbożowej z dodatkami, takimi jak: trociny olchy, siano łąkowe oraz ziarno owsa. Uzyskane wyniki posłużyły do celów porównawczych podstawowych parametrów fizyko-chemicznych brykietów. Określono, że brykiety uzyskane z połączenia słomy i trocin olchy wykazują najwyższą wartość opałową. Dodatkowo odnotowano zwiększoną zawartość pozostałego po spaleniu popiołu w próbkach, które miały wyższą zawartością węgla, co może wskazywać na straty związane z niecałkowitym spalaniem.

This paper presents the results of the caloric value, content of water, ash and carbon, nitrogen and hydrogen in the four types of briquettes. Material consisted of wheat straw briquettes with additives such as alder sawdust, meadow hay and oats. The results were used for comparison purposes of the basic physicochemical parameters of briquettes. It was determined that the briquettes obtained from a combination of straw and alders sawdust have the highest caloric value. In addition, the increased level of ash remaining after burning in the samples, which had higher carbon content, was reported which may indicate losses related to incomplete burning.
