Abstract—The paper investigated the effects of irrigation of Spreading of poultry wastewater to land as fertilizer is a
poultry waste water on soil fertility and biomass production of traditional, economical and effective disposal method [4].
cabbage in accordance with the standard of Environmental Because of the advantages of land-spreading mode, such as
Technical Terms for Green Food Production Area (NY/T391- realization of maximum resource utilization, reduction of the
2000). The results showed that irrigation of per hectare applied fertilizer, improvement of soil fertility and
every 10 days resulted in the highest production of biomass of conservation of investment, about 90% of breeding farms in the
cabbage as well best soil fertility index. When a farm garden with United States adopt land-spreading mode to dispose poultry’s
considerable scale is available, abatement of poultry wastewater wastes [5]. Britain and the other European countries have
from intensive breeding farm by internal industrial chain begun to change breeding technology from cleaning
