Effect of the long-term application of different fertilization systems on soddy-podzolic soils

Effect of liming on the change of some agrochemical soil properties in a long-term fertilization experiment

“…The lowest pH value (3.4) was reported for the FYM NPK fertilization treatment (Table 1). The results of long-term experiments in many countries of the world show that regular application of farmyard manure limits soil acidification and intensive mineral fertilization; especially with nitrogen and potassium, it results in a decrease in pH value, and even in soil degradation (Gomonova et al 2007, Shahid et al 2013). This long-term experiment at Mochełek (Poland) shows that the use of FYM only once in crop rotation, on average every 5 years, on light soil with a relatively low organic matter content and a lack of liming did not limit the acidifying effect of mineral fertilization.…”

Translocation of heavy metals and methods of their detoxification in podzolized chernozem

“…According to the researchers [9][10][11][12][13][14][15], the majority of mobile compounds of heavy metals are confined to the humus, humus-eluvial horizons, where the roots of plants, in which biochemical processes are actively occurring and which contain a lot of organic substances, are located. Under the influence of contamination by heavy metals of the soil, organic complexes, which have high mobility, are formed in it.…”
