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:
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.

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.
