Abstract
Sustainable livestock effluent management is becoming an increasingly important issue in Cam Lam district of Khanh Hoa province, with particular regard to the agro-environmental performance of forage production and the social acceptability of organic fertilizer application in mixed urban-rural contexts. The present paper proposes a GIS-based methodological approach to the management and planning of digestate spreading on hay meadows, based on the integration of spatio-functional database about cultivated agricultural land. The proposed methodology was tested in Cam Lam district, with pig 78 farms. Environmental parameters of TSS, BOD5, COD, nitrogen production by pig was quantified and compared to sustainable requirements provided by national and local regulations were spatially implemented. Findings are transferrable to other regions based on cattle farming management.
Keywords: livestock effluents, organic fertilization, pollution, Cam Lam district, Khanh Hoa province.
