The objective of our work is to study the influence of the contribution of Fragmented Rameal Wood (BRF) and cattle manure on the density of microscopic fungi and the density of mites and springtails of a limono-sandy soil in Constantine (Algeria). A 100 m² parcel is subdivided into 15 plots of 2 m² each with 5 different plots where we determined the species of microscopic fungi and their density during March, April, May, June and November 2014. Thus, the density of springtails and mites was monitored monthly from March 2014 to January 2015. The results obtained show that the contribution of BRF or BRF mixture to cattle manure have a beneficial effect on the evolution of the density of microscopic fungi and the density of springtails and mites in the amended plots compared to the unamended plots.&nbsp

The presence of organic matter in agricultural soils is an important factor in assessing the conditions of the soils. BRF and Manure are energy inputs that can improve the soil. The objective of our work is to study the influence of the contribution of Rameal Fragmented Wood (RFW) and cattle manure in the presence and absence of earthworms Octodrilus complanatus on the germination rate (%) of durum wheat (Tritucum durum) of the Hedba 3 variety. The study station is located in a semi-arid zone (Constantine, Algeria). the results obtained show that the contribution of RFW or RFW mixture and cattle manure in the presence and absence of earthworms Octodrilus complanatus has a beneficial effect on the the germination rate increased by 193.35% on average in the amended plots compared to the control plots.
