A PILOT STUDY TO EVALUATE THE USE OF DATE PALM RESIDUES (LEAVES, LIF, KORNAV) AS ORGANIC FERTILIZER IN THE DESERT AREAS
The aim of this work is to promote the use of local organic wastes (leaves, lifs, Kornav) of date palm, as organic fertilizer, to improve the microbiological activities of sandy soil, especially the process of carbon mineralization. To do this we adopted the method of incubation under controlled parameters on representative samples of sandy soils of arid regions. It is a sandy soil taken from the southern region of Algeria, Ouargla. The analysis of overall results demonstrated a positive and significant effect of date palm residues on soil microbial activity. Thus, after 42 days of incubation, the cumulative amounts of CO2 released are 14.37 and 40.02 mg/100 g dry soil, respectively in soil enriched and unenriched (control) by the residues of date palms. Regarding the influence of these residues on microbial density, we observed a stimulatory effect of functional groups studied (cellulolytic and amylolytic germs) as well as total and fungal microflora. The overall results show the advantage of using date palm residues for improving microbiological functioning and microbial density of the sandy soil of desert areas.
