Nutrient recovery from swine waste and protein biomass production using duckweed ponds (Landoltia punctata): southern Brazil.
Brazil is one of the most important countries in pork production worldwide, ranking third. This activity has an important role in the national economic scenario. However, the fast growth of this activity has caused major environmental impacts, especially in developing countries. The large amount of nitrogen and phosphorus compounds found in pig manure has caused ecological imbalances, with eutr...
متن کاملHigh nutrient removal rate from swine wastes and protein biomass production by full-scale duckweed ponds.
Duckweed ponds have been successfully used in swine waste polishing, generating a biomass with high protein content. Therefore, the present study evaluated the efficiency of two full-scale duckweed ponds considering nutrient recovery from a piggery farm effluent (produced by 300 animals), as well as the biomass yield and crude protein (CP) content. A significant improvement in the effluent qual...
متن کاملAssessing Nitrogen Use Efficiency and Nitrogen Loss in a Forage-Based System Using a Modeling Approach
In intensive agriculture, N supply often exceeds crop requirements, even in nitrate vulnerable zones (NVZ). In farmland, the N surplus gives rise to NO3 ́ leaching and consequent groundwater pollution. The present study aimed at proposing measures to reduce N leaching and hence improve N efficiency in a buffalo livestock farm located in the NVZ of Latina plain (Central Italy). The farm was culti...
متن کاملBioflocculation technique for microalgal harvesting and wastewater nutrient recovery
Fungal assist microalgal cultivation is getting substantial considerations due to the highly efficiency of bioflocculation process without demanded of using chemicals and little bit energy input. Therefore, Fungi pelletization-assisted microalgal cultivation were applied for improving algal harvesting process and nutrient recovery as step wise for wastewater treatment. Two strains of marine mic...
متن کاملSeasonal Nutrient Yield and Digestibility of Deer Forage from a Young Pine Plantation
Six classes of current herbaceous and woody forage were collected seasonally from a 5-yearold mixed loblolly (Pinus taeda) -shortleaf pine (Pinus echinata) plantation (in Texas) and subjected to nutrient analyses and nylon bag dry-matter digestion trials. Forages were most nutritious and digestible in the spring when tissues were succulent and growing rapidly. Browse leaves and twig tips were t...
