THE IMPACT OF THE LONG ‒ TERM FERTILISATION WITH MINERAL FERTILISERS ON THE CHEMICAL PROPERTIES OF VERTISOL (CENTRAL SERBIA)

open access: yesApplied Ecology and Environmental Research, 2019
© 2019, ALÖKI Kft., Budapest, Hungary. The study is based on establishing soil acidity and fertility of Vertisols after the mineral fertilisers had continuously been applied from 1984 to 2016. The two phosphorus (35 and 70 kg P ha-1), the invariable nitrogen (120 kg N ha-1) and potassium (66.4 kg K ha-1) doses were used in Kragujevac location (central ...
