cow dung composition

d) Carbon content is low. e) Burning ratio is low. Fresh cow dung was collected early in the morning from pens and heaped up. Cow Dung Collection, Duration of Storage/Ageing in the Field before Application and Incorporation The cow dung that was used for these experiments were collected from the National Animal Production Research Institute (NAPRI), Shika-Zaria in years 2003 and 2004. Total Solids Content (TS) Manure Removed As: 1% 2% 4% 6% 8% 10% 12% 14% Thick Slurry – minimal water 2.31 a 1.92 b 1.65 Slurry + Milking Center Waste 3.85 2.88 Slurry + Parlor Flush 5.77 3.85 Alley Flush 11.54 5.77 All Facilities Flushed 23.07 11.54 For example. The animal metabolizes the feed to provide itself with energy and produce new body tissues and products. For camel manure, the pH was 8.6 in fresh and 8.5 in compost, for cow manure pH was 8.5 in fresh and 7.4 in manure compost. Poultry manure had a pH of 8 in fresh and 8.4 in compost. The manure is used as a rich fertilizer, an efficient fuel and biogas producer, a useful building material, a … if I have 150 kg of cow dung and 900 kg of wastewater (mixing ratio 1:6) under 25-degree Celsius and 1 bar, what are the main reactions ( Hydrolysis, Acidogenesis, Acetogenesis, Methanogenesis) with respect to the cow dung composition and … c) It has low volatile content after burning. Physical properties of cow dung: a) It is bulky b) It has large ash content. The chemical characteristics of manure primarily depend upon the chemical composition of the feed given to the animal. 1 Listed as P 2 O 5; multiply by 0.437 to convert to P 2 Listed as K 2 O; multiply by 0.83 to convert to K. The categories of nitrogen, phosphorus, and potassium content (after losses) in Table A-8 were added to provide a mechanism for estimating the amount of nutrients that would be present in land applied manure and effluent. Cow dung is somehow a type of FYM that is mostly excreta of cattle may contain water ~95%, urea ~2.5%, hormones, salts, and enzymes ~2.5%. Composition of Manure. The primary factors that affect nutrient composition of manure are livestock type, stage of growth and feeding practices (all of which determine nutrient excretion rates) as well as the amount of bedding or water added to the manure, type of manure storage, time that the manure spends in storage and weather conditions. rbon, nitrogen, hydrogen, oxygen, phosphorus, etc. with salts, cells sloughed Cow dung harbours a diverse group of microorganisms that may be beneficial to humans due to their ability to produce a range of metabolites. Exact chemical composition is of mostly ca. Cow dung, an excreta of bovine animal, is a cheap and easily available bioresource on our planet. Beside cow/ cattle manure (FYM), the substantial quantities of liquid manures (dungs/urines) can be effectively utilized for remediation of Cd-contaminated soils. Cow manure has a soft texture and tends to be deposited in a circular shape, which gives dung patches their alternate names of cow pies and cow pats. Goat fresh manure showed pH of 8.9 and 7.8 in composted manure. The pH of buffalo manure was 8.7 in fresh and reduced to 7.7 in composted sample. Because a cow's stomach includes four different chambers with their own chemical processes and biological functions, the chemical composition of cow dung includes a variety of different substances. Although NPK contents of cow and goat manure varies with several factors as stated by Kenneth Masuki, you may use the following average values of N, P and K for comparison of the two animal manures: 3a - 3 Table 3.1. lb/cow Annual manure N, lb/mature cow Annual manure P, lb P2O5/mature cow N:P 2O5 20,000 361 63 2.5 25,000 382 63 2.7 After 30% N loss by NH 3 volatilization 20,000 253 63 1.8 25,000 267 63 1.9 Typical N:P 2O5 ratio of harvested material Various non-legumes 2.3-3.0 Alfalfa 4.9 1. Variation of dairy manure production (ft3 / AU - day) depending on consistency of removed manure. Many traditional uses of cow dung such as burning as fuel, mosquito repellent and as cleansing agent are already known in India.
