Composting agricultural waste and residues and returning them to agricultural lands and
nature is important both to compensate for the lack of organic matter in the soil and to
prevent environmental problems. In this study, hazelnut husk and pruning waste obtained
from a hazelnut orchard were composted under aerobic conditions by inoculating with
microorganisms extracted from forest soil and fresh farmyard manure. The organic waste
materials were laid down as a pile in the windrow composting unit and composted around
60-70% moisture condition. Temperature, pH, EC, organic C, C/N ratio, total P, total K, CO2
production and microbial biomass C contents of the compost pile were determined during
the 45-day composting period. According to the results, the temperature of compost pile
reached thermophilic phase after 6 days, and the highest temperature was measured as
56°C at the 14th day. The C/N ratio and pH of the compost pile were changed from 60
and 8.53 initially to 30.13 and 7.38 at the end of 45 days, respectively. While the total P
content increased by approximately 30%, there was no significant change in the total K
content. It can be concluded that hazelnut husk and pruning waste can be successfully
composted with windrow method with microbial inoculation around 7 weeks without
using any other farmyard manure or other waste to reduce C/N ratio.
