Opis:
The subject of the study was an analysis of the impact of multicomponent mineral fertilizers manufactured in Poland and abroad, on changes in the content of available phosphorus and potassium as well as exchangeable magnesium in the soil. The study also looked at the effect of varying doses of multi-component fertilizers produced in Belarus, Russia and Poland. The experiments were carried out in 2015–2017 in Poland. The experimental plant was winter oilseed rape. The use of compound fertilizers of Belarusian, Russian, and Polish production did not have a significant impact on changes in soil pH during rapeseed cultivation. No differences in the effect of multicomponent fertil-izers on changes in the content of available potassium and ex-changeable magnesium were found. In the soils of both experi-ments, increasing the doses of tested multicomponent fertilizers had significant influence on the increase in the amount of avail-able potassium and did not cause any changes in the abundance of exchangeable magnesium in the soil. Generally similar effects of multicomponent fertilizers Belarusian, Russian and Polish origin on investigated soil properties were noticed.

Opis:
Zróżnicowanie jakości, oferowanych na rynku nawozów dwuskładnikowych różnych producentów polskich i zagranicznych uzasadnia prowadzenie badań dotyczących ich oddziaływania na rośliny i glebę. Celem badań była ocena wpływu rodzaju i dawki mineralnych nawozów dwuskładnikowych na zawartość makroskładników w glebie po uprawie buraka cukrowego. Doświadczenie prowadzono w latach 2014–2017 w miejscowości Lipnik. Rośliną doświadczalną był burak cukrowy odmiany Natura KWS. Dwuczynnikowe doświadczenie polowe przeprowadzono w układzie losowanych bloków. I czynnikiem było pochodzenie dwuskładnikowego nawozu mineralnego (N – 18%, P2O5 – 46%): produkcji rosyjskiej, litewskiej i polskiej (POLIDAP®). II czynnikiem była dawka nawożenia fosforem oraz azotem: minimalna, optymalna, maksymalna – odpowiednio 1,0, 2,0 i 3,0 dt nawozu dwuskładnikowego na hektar. Zastosowano nawożenie potasowe w ilości odpowiednio: 1,25, 2,50 i 3,75 dt na hektar w postaci chlorku potasu. W kolejnych latach (2015, 2016 i 2017 r.) realizacji doświadczenia podczas uprawy buraka cukrowego wykonano te same zabiegi agrotechniczne. Nawożenie nawozami dwuskładnikowymi produkcji rosyjskiej i litewskiej nie spowodowało zmiany odczynu gleby. Zastosowanie POLIDAPU® spowodowało istotny spadek pH gleby. Po zastosowaniu nawozu rosyjskiego zasobność gleby w fosfor pozostała na poziomie średnim. W obiektach z nawozami produkcji litewskiej i polskiej zawartość fosforu przyswajalnego w glebie oceniono jako wysoką. Kolejne dawki nawozów powodowały wzrost zawartości fosforu przyswajalnego w glebie, o 12,9, 15,5 i 20,5%, i nie był on proporcjonalny. W doświadczeniu nie stwierdzono zróżnicowanego działania nawozów dwuskładnikowych produkcji: rosyjskiej, litewskiej i polskiej na zawartość w glebie wymiennego magnezu.
The diversity in the quality of the two-component fertilizers manufactured by various Polish and foreign producers and present on the market, justifies research into their impact on plants and quality changes in the soil. The aim of the research was of analyze the impact of mineral two-component fertilizers produced by: Russian, Lithuanian and Polish manufacturers on changes in the content of macroelements, in soil after sugar beet cultivation. The effect of doses of the fertilizers used was also analyzed. The experiment was carried out in the years 2014–2017 in the Lipnik. The experimental plant was sugar beet variety Natura KWS. Two factors were compared in the studies: I factor – 3 two-component mineral fertilizers, Russian, Lithuanian and Polish POLIDAP®. II factor – 3 doses of two-component fertilization (minimal, optimal, maximum), which were 1.0, 2.0 and 3.0 dt per hectare respectively). Potassium fertilization was applied at rates of 1.25, 2.50 and 3.75 dt per hectare as potassium chloride. Fertilization with two-component fertilizers produced in Russia and Lithuania did not change the pH of the soil. The use of POLIDAP® caused a substantial soil acidification. After applying the Russian fertilizer, the soil’s phosphorus fertility remained at the medium level. The introduction of Lithuanian and Polish fertilizers into the soil changed the values of the content of phosphorus available in soil from low to high. Increasing the dose of fertilizers by 50% caused an increase in the content of phosphorus available in the soil, but it was not proportional to fertilizer rate. There were no discernible differences of the two-component fertilizers produced in Russia, Lithuania or Poland in terms of the content of removable magnesium in the soil.

Opis:
The subject of the study was an analysis of the influence of two-component mineral fertilizers of Polish, Lithuanian and Russian production on the changes in the soil pH and the contents of available phosphorus and potassium as well as exchangeable magnesium after winter rape cultivation and the content of macroelements in winter rape seeds. The study also focused on the effect of using varying doses of fertilizers. A two-year field experiment was carried out on soil belonging to loamy sand, the IVa bonitation class. The experimental plant was winter rape, DK EXPLICIT hybrid. The experiment was established using random blocks design in 4 replicates. Two factors were compared in the studies: I. factor – 3 two-component mineral fertilizers of Russian, Lithuanian and Polish production (POLIDAP®). II. factor – 3 doses of fertilization (minimum, optimum, maximum, which were respectively: 1.0, 2.0, 3.0 dt per hectare). Introducing the two-component fertilizers and diversification of their doses was a factor that did not change the soil acidification. The applied two-component fertilizers (Russian, Lithuanian and Polish POLIDAP®) caused an increase in the amount of available phosphorus in the soil, with no differences depending on the fertilizer type. Diversification of the two-component fertilizers and potassium salt doses was reflected in a significant, but not proportional to the dose, increase in the amount of available phosphorus and potassium in the soil. While using fertilizers of Russian, Lithuanian and Polish production (POLIDAP®) during rape cultivation, there was no difference in the nitrogen, phosphorus, magnesium and sulfur contents in the seeds of cultivated winter rape of hybrid DK EXPLICIT cv.

Opis:
The aim of the present paper is to assess the effect of cultivation systems and varied nitrogen fertilisation doses on yield and yield components of two cultivars and one strain of winter spelt. The experiment was conducted on soil is classified as Haplic Cambisol. Three factors were compared in the course of the experiment: factor I – 2 cultivation systems: reduced tillage and conventional cultivation, factor II – 4 nitrogen fertilisation levels, factor III – cultivar/strain. The plants under analysis were two cultivars of winter spelt: German ‘Frankenkorn’ and Swiss ‘Oberkulmer Rotkorn’ and strain STH 12. There was no significant difference regarding winter spelt grain yield depending on the cultivation system. Nitrogen fertilisation caused a significant increase in yield to a certain threshold which, when exceeded, resulted in a decrease of grain yield. The highest yield was obtained for STH 12 strain. With respect to thousand grain weight, number of ears per m2, number of grains yield per ear, and ear yield, there was a significant relationship with the cultivar factor. SPAD values showed no differences between cultivars. The method of cultivation (conventional vs. reduced tillage) did not show differences for the four analysed yield components and SPAD of winter spelt.

The paper the results obtained during hard coal ash reclamation. This model was created by covering the ash surface with the layers consisting of ash, organic by-products and mineral fertilizers. The aim of the studies, undertaken 15 years after the experiment set up, was the assessment of the efficacy of ash waste reclamation on the basis of the overall and solubility analyses of the metal content, including heavy metals, soluble in 1 M HCl. In 2003, on the premises of Dolna Odra Power Station in Nowe Czarnowo (53,20°N; 14,48°E) near Gryfino (53,25°N; 14,48°E) in Poland, a hard coal ash reclamation experiment was conducted. A 40 cm thick surface layer (fertile), termed upperlay, composed of the mixture of various materials was applied to ash substrate. One part was fertilized with mineral fertilizers NPK-60–70–70, the other was left unfertilized. After 15 years, in the autumn of 2018, the samples of upperlays (0–40 cm) and underlays (40–60 cm) were collected from plots overgrown with grass. Fifteen years after the experiment, none of the underlays or upperlays showed an excess of threshold values, as specified in the current Regulation of the Minister of the Environment of 2016. The particularly favourable effect was identified with respect to the application of fermented municipal sewage sludge and GWDA compost which were factors resulting in a decrease of the upperlay content of cadmium, zinc, copper and lead in the form available for plants. The characteristics of upperlays with respect to metal content indicate the conditions favourable to plant cultivation on the reclaimed area. The recorded results on the change of the overall and bioavailable content of metals in upperlays and underlays justify the continuation of the undertaken reclamation experiment.

Opis:
This paper presents the results obtained during reclamation of hard coal ash. The model was developed by covering the layer of ash with layers containing ash, organic by-products and mineral fertilizers in 10 different combinations. The experiment on reclamation of hard coal ash was conducted in 2003 on the premises of Dolna Odra Power Station in Poland. The physicochemical parameters of top layers were well suited for cultivation on the reclaimed land. Particularly favourable was the introduction of fermented municipal sewage sludge to top layers. In this way, the appropriate structure of the analysed top layers was obtained, as manifested by good abundance of forms of magnesium, potassium and phosphorus available for vegetation. The obtained results demonstrate the process of accumulation of the available forms of magnesium, potassium and phosphorus in underlays when the fertile surface layer is supplemented with fermented municipal sewage sludge. The results obtained in the experiment indicate, that hard coal ashes can be managed in this way. Due to the long-term character of physicochemical and chemical properties of both top layers and underlays, the results presented here justify the continuation of the conducted reclamation experiment.
