Abstract
In 2015-2016, research was carried out on a Haplic Luvisol (LV-ha) with predominant sandy loam and a pH KCl of 4.9-5.2 with a view to finding out how composts produced from sewage sludge, green waste and biogas production waste influenced potato tuber, spring oilseed rape seed and threshing residues yields as well as the concentrations of nitrogen (N), phosphorus (P), potassium (K) and heavy metals in tubers, seeds and threshing residues. An experiment was conducted in the fields of Elmininkai Experimental Station (Anykiai distr., Eastern Lithuania) of the Lithuanian Research Centre for Agriculture and Forestry. The composts were incorporated into the soil twice, in September in 2012 and in October in 2014. The mineral fertilisers used were ammonium nitrate, granular superphosphate and potassium chloride. Mineral fertilisers were applied in spring prior to sowing. Potato tuber yield in the treatments without mineral fertilisation was significantly increased by all types of composts applied in the experiment: biogas production waste compost -by 48.0%, green waste -43.5%, cattle manure -33.9% and sewage sludge -27.5%. However, these composts did not increase spring oilseed rape seed and threshing residues yields. Mineral fertilisers had a greater impact on them -the achieved seed yield increase was 40.4% higher. Chemical composition analyses of potato tubers, spring oilseed rape seeds and threshing residues showed that biogas production waste compost increased N concentration. In potato tubers K concentration was increased by all investigated composts, but most of all -by that of manure. In rape seeds, K concentration was increased by biogas production waste, sewage sludge and manure composts. In the yields of the investigated plants P concentrations were not affected by any of the composts applied. Compost influence on the variations of individual heavy metal (Cu, Zn, Mn, Pb, Cd and Ni) concentrations in potato tubers, spring oilseed rape seeds and threshing residues was different.
