Improved performance of red worms (Eisenia andrei) in compost of cattle manure rinsed with water
To achieve satisfactory results with vermiculture, it is important to know how many times to rinse cattle manure to eliminate salts. Treatments under evaluation were 0, 1, 2, 3, 4, 5, 6 or 7 rinses in a tap water: manure ratio of 1 : 1 (v/v). Electrical Conductivity (EC), Biomass of Worms (BW) and Number of Cocoons (NC) were evaluated. The EC ranged from 2.57 to 0.5 dS·m−1 for T0 and T4. ...

Nitrate leaching in two irrigated soils with different rates of cattle manure
Received for publication December 15, 2008. Manure applied to irrigated land may potentially contaminate groundwater with NO3–N. An 8-yr field experiment was conducted in southern Alberta, Canada, to determine the effects of different rates of manure on NO3–N accumulation in two irrigated soil types and NO3–N leaching to shallow groundwater. An annual cereal silage was grown at each site and ...

Equipment of dairy cattle manure treatment organic fertilizer
Now we can see that many dairy farms, chicken farms and other farms are going to buy organic fertilizer equipment. Why? First of all, because the organic fertilizer production equipment can treat the manure of livestock and poultry into organic fertilizer, which fundamentally solves the pollution caused by the manure of livestock and poultry, so that the environmental problems in the farm can be ...

Cattle manure application strategies effects on bahiagrass yield, nutritive value, and phosphorus recovery
Animal manure application based on crop N requirements often leaves excess P in the soil because of the differences in the N/P ratio in manures and that required by the plants. This experiment was designed to evaluate the effects of cattle (Bos taurus) manure applied alone or in combination with ammonium nitrate (AN) on bahiagrass (Paspalum notatum Flügge) dry matter (DM) yield, nutritive value, ...

Dairy cattle manure improves soil productivity in low residue rotation systems
Mineral fertilizer alone may not sustain soil productivity in cropping systems that return little crop residues to the soil, unless additional organic residues and/or manure is applied regularly to the soil. The objective of the present study was to assess the long-term effects of mineral fertilization (No fertilizer, PK, and NPK) and manure addition (0 and 20 Mg ha–1 yr–1) on soil physical and ...

Function characteristics of cow manure organic fertilizer production equipment
Cattle farms produce a lot of cow dung every day, so it is necessary to pay attention to the treatment of odor, odor collection and construction of deodorization facilities. The fermentation period of cow manure is about 15 days. Compared with traditional farm manure, the fermentation period is shorter and the maturity is higher. The fermentation period will not seriously affect the surrounding ...

Effect of covering composting piles with mature compost on ammonia emission and microbial community structure of composting process
Received for publication February 14, 2008. To control ammonia (NH3) volatilization from the dairy cattle (Bos taurus) manure composting process, a compost pile was covered with mature compost and the gas emissions evaluated using the dynamic chamber system. The peak of NH3 volatilization observed immediately after piling up of the compost was reduced from 196 to 62 mg/m3 by covering the compost ...

Nitrogen immobilization and mineralization kinetics of cattle, hog, and Turkey manure applied to soil
Nitrogen mineralization and immobilization following manure application are critical processes influencing plant N supply and offsite N losses. We conducted laboratory experiments to examine the influence of these two processes in addition to N oxide gas production on N availability for 180 d following manure addition. A Tara loam (fine-silty, mixed, superactive, frigid Aquic Hapludoll) and a ...

Selected antimicrobial resistance during composting of manure from cattle administered sub-therapeutic antimicrobials
Received for publication December 10, 2007. Composting is being increasingly employed for the recycling of nutrients in manure from the livestock industry. However, composting manure from animals fed antimicrobials has not been well characterized. In this study, compost windrows were prepared using manure collected from cattle (Bos Taurus L.) fed tylosin (TY), chlortetracycline-sulphamethazine ...

How much is the small pig manure organic fertilizer equipment?
How much is the farm, chicken, pig, cattle, small chicken manure organic fertilizer equipment, pig manure processing equipment, how much is the profit of organic fertilizer plant? What is the process flow of organic fertilizer production line? The output and price of pig manure organic fertilizer production line are different. How much is the small organic fertilizer equipment? With an annual ...

Effects of dried distillers` grains with solubles (wheat-based) in feedlot cattle diets on feces and manure composition
The use of dried distillers' grains with solubles (DDGS) in feedlot cattle (Bos taurus) diets is increasing as the bio-ethanol industry expands. This study investigated how wheat (Triticum aestivum L.) DDGS-based diets impact feedlot cattle nutrient and volatile fatty acid (VFA) excretion. Feedlot heifers were fed DDGS at 0 (Control) 20, 40, 60% or 60% + Ca (1% limestone) of dietary dry matter. ...
