Soil urease is an enzyme catalyzing the hydrolysis of urea. The activity of the enzyme influences the content of ammonia ions in soil and thereby the fertility of the soil. 5-hydroxy-1,4-naphthalenedione (juglone) is a compound which inhibits urease. The compound is released by trees of the Juglandaceae family (walnut trees) and is present in their leaves, roots, husks and fruits. The aim of the study...
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 multicomponent fertilizers produced in Belarus, Russia and Poland. The experiments were carried out in 2015–2017...
The focus on speciation analytics, which allows identification of the potential risks to the environment arising from the presence or accumulation of heavy metals in soil, has been on the increase in the recent years. Total or, at least, partial detoxification of heavy metal ions, to variable extents, can be achieved by introducing biochar into the soil. The key factor and potential of biochar to...
