Biological processes which shape soil fertility are affected by microorganisms and enzymes they produce as well as the rate of biogeochemical transformations in the cycling ofelements. One of the enzymes is arylsulphatase (EC 3.1.6.1.), which hydrolyses sulphate esters with aromatic radical, releasing sulphate ions according to the equation: R-C-O-SO3- + H2O R-C-OH + SO42- + H+. The enzyme plays...
In a vegetation experiment, the effect of composts made from unsorted municipal solid waste and urban green waste on the content of zinc in plants has been analyzed. The municipal waste composts matured in heaps for 1, 3 and 6 months. They were applied in three rates: 10, 20 and 30 g kg–1 of soil. The compost made of urban green waste aged in a pile for 6 months and was added to soil in the amount...
Numeorus analytical methods have been developed for determination of micronutrients, heavy metals and trace elements in soil. However, rapid and easy-to-perform methods are still needed for chemical composition analysis of soil that would be based on simultaneous extraction of multiple elements. Furthermore, it would be beneficial if element concentration in soil using these methods were correlated...
