A
gricultural waste removal has become an ecological
problem, brought to light as a result of an increase in
public health concerns and environmental awareness.
Aerobic and anaerobic treatments of agricultural wastes
appear to be the most promising approaches for reducing
agricultural wastes going to landfills while producing
environmental and socio-economic benefit. In view of the
above considerations, the objective of this study was to
analyze the chemical characteristics of two composts and two
digestates and to compare their effects on soil chemical, and
biochemical properties and on crop productivity and quality
to determine their suitability as fertilizer. Results evidenced
that waste characteristics influenced the chemical properties
of the compost much more than composting process. The
obtained composts had a positive effects on soil, increasing
organic matter (SOM), nutrients, microbial biomass (MBC),
bacterial and fungal population. The best result on soil,
was obtained by using the compost produced with a mix of
broadleaf vegetables. Regarding crop productivity, the data
showed a specificity between crop and type of compost
used. Digestates positively affected soil chemical and
biochemical parameters depending on the type of fraction
and on the concentration used. The digestates were less
effective than compost in inducing crop productivity and
quality. In conclusion, the agronomic quality of compost
and digestate is strictly dependent on percentage and type
of feed stocks used in the aerobic or anaerobic process. The
results confirm that compost and digestate offer important
soil improvements that are mutually beneficial rather than
alternative, even if the compost is better than digestate in
inducing crop productivity and quality.
