The influence of Ramial Fragmented Wood and manure on some physico-chemical parameters of a sandy loam soil in Constantine (Algeria)

The objective of our work is to study the influence of the contribution of Rameal Fragmented Wood (FRW) and cattle manure in the presence and absence of earthworms Octodrilus complanatus on some physicochemical parameters of a sandy loam soil such as porosity, carbon, nitrogen and C/N ratio. The study station is located in a semi-arid zone (Constantine, Algeria). The results obtained show that the contribution of FRW or FRW mixed with cattle manure in the presence and absence of earthworms Octodrilus complanatus has a beneficial effect on the studied physico-chemical parameters.
