Waste application, beneficial in terms of soil abundance in nutrients, cannot lead to soil contamination. The incubation experiment aimed at assessing the effect of applying sulfur pulp (waste material containing elemental sulfur) and ground phosphate rock on the availability of heavy metals in soils. The experiment was conducted on two soils with different soil category: medium and heavy, both of acid reaction and not contaminated with heavy metals. Doses of sulfur pulp and phosphate rock were set based on soil a...

Mushroom production generates a considerable amount of spent mushroom substrate, difficult to utilize at the site of production. The high amount of organic matter and nutrients in the waste justifies its environmental use. However, waste entering the environment undergoes transformations, the direction and intensity of which depend on, among other things, environmental conditions. Extreme environmental conditions (such as very low or high pH) can significantly change the properties of introduced material and, as a...
