Integrated fish farming combines livestock production with fish farming. Animal manure is shed directly into a fish pond as fertilizer and supports the growth of photosynthetic organisms. The livestock, mainly chickens and pigs, is often fed feed containing growth promoters. In this study we investigated the impact of integrated fish farming on the levels of antimicrobial-resistant bacteria in ...

Direct measurement of ventilation rate in livestock housing can be a formidable task due to uncontrollable variations in fan and system performance as caused by factors such as operation static pressure, fan belt condition, and dust accumulation on shutters and blades. Indirect, CO2-balance method offers a potentially viable, more flexible alternative to estimating ventilation rate. The reliabi...

It is inevitable that with large volume and high density poultry productions, there will be large quantities of poultry waste produced in Kathmandu and throughout Nepal. Poultry waste produced as the daily feeding of chicken both from broilers and layers in the country is largely used as organic manure for agricultural purposes. The poultry industry is growing day by day concentrated within the...

Nitrogen and carbon mineralization rates of 19 manure and compost samples were determined in 1996, with an additional 12 samples evaluated in 1997. These organic amendments were mixed with a soil : sand blend at 2% by dry weight and the amended blends were incubated at constant moisture for 12 (1996) or 24 weeks (1997) at 25 °C. Net N mineralization was measured at 4(1996) or 8-week (1997) inte...

The effort taken to increase shallot production both in quality and quantity is use fertilizer. One type of organic fertilizer that will be used bokashi chicken manure. Bokashi a fermentation matter by inoculation EM4 which mixed culture beneficial microorganisms for plant growth such as Lactobacillus sp, photosynthetic bacteria, actinomycetes yeast. purpose this study was determine the effect ...

As an environmental management method, the (life cycle assessment) LCA method can be used to compare differences between various waste treatment processes in order provide environmentally friendly and economically feasible for management. This study focused on reutilization of typical organic produce fertilizer southwest China life assessment evaluate three aerobic chicken manure composting sce...

As a potential adsorbent material, loose, porous livestock manure biochar provides new approach to resource utilization. In this study, coconut husks (CH) and manure, i.e., cow dung (CD), pig (PM), chicken (CM) were used as biomass precursors for preparation of via high-temperature pyrolysis CO2 activation. Characterization technologies, such scanning electron microscopy, Fourier transform infr...

The objective of the present study is to investigate the effects of irrigation water salinity,cow manure levels and different planting methods on ions variation in soil and their uptake bysaffron. A split-split plot arrangement was conducted in a randomized complete block designwith irrigation water salinity levels (0.45 (fresh water, S1), 1.0 (S2), 2.0 (S3) and 3.0 (S4) dS m-1)as the main plot...
