Most of the 60 participants on the tour had never seen an industrial scale compost turner before Wholesale Jerseys China Free Shipping , so Gerry Dub茅, interim director of the Compostages Manitoba Services Co-op, had to field more than a dozen questions about the machine and composting.
Last summer, Dub茅 and other producers in southeastern Manitoba formed the compost co-operative, the first of its kind in Canada, which owns and operates the windrow turner.
The co-operative rents out the turner to members and non-members so livestock producers can manage the compost on their farm.
After holding demonstrations and attending meetings over the last year, the co-op now has 26 members 鈥?mostly cattle and dairy farmers in southeastern Manitoba.
鈥淲ith one machine we could probably serve between 60 to 75 (members) Wholesale Jerseys Online ,鈥?said Dub茅, who farms near La Broquerie and used to run a business called BDM Composting.
The machine, a Backhus 17.50, made in Germany, can handle a windrow of manure that is 4.9 metres wide and 2.5 m high (16 by eight feet). The machine, which straddles the windrow and runs on tracks, can turn 400 tonnes of manure Wholesale Jerseys Free Shipping , or more, per hour.
Standing next to a 250 m long windrow of manure at a farm near Marchand, Man., Dub茅 said each lineal foot of the windrow represents one tonne of manure.
Members of the co-op must pay $500 for the first hour of compost turning on their farm and $250 for every subsequent hour. It isn鈥檛 cheap to convert manure into compost, but it does substantially cut the cost of transporting raw manure from a feedlot to the field, said Katherine Buckley, an Agriculture Canada scientist in Brandon.
Back in the late 1990s Wholesale Jerseys From China , Buckley and other scientists at the Brandon Research Centre wanted to haul manure from the centre and apply it to fields south of town.
After evaluating their options they realized that composting was the best option.
鈥淚nstead of hauling 10,000 tonnes of raw manure, we were hauling four or five thousand tonnes of compost,鈥?she said.
While hog manure is readily available in southeastern Manitoba, composting has several advantages over injecting hog manure, Dub茅 said.
鈥淐ompost is about 40 percent moisture. So you鈥檙e hauling way less moisture out onto the field,鈥?he said Wholesale Jerseys China , noting that hog manure is nearly all water.
Further, adding compost increases the amount of organic matter and helps the soil hold more water, Dub茅 said, who explained that most producers in the co-op apply their compost to cropland.
From an economic perspective, producing and applying compost probably makes the most sense for high value crops like potatoes, Buckley said.
鈥淚 think that鈥檚 where the biggest bang for the buck is鈥? If you take the actual value of nutrients, right now with the price of fertilizer Wholesale Jerseys , compost is very competitive in terms of value per kg.鈥?p>
Using a potato crop as an example, Buckley said the long term impact of compost isn鈥檛 well understood. Nonetheless, there is evidence that compost can build up nutrient reserves in the soil.
鈥淎fter you apply compost in the potato year (of the rotation), your rotational crop may not require any nutrients. That鈥檚 a huge benefit.鈥?p>
In spite of its positive attributes, only a fraction of livestock farmers in Western Canada turn their manure into compost, Buckley admitted.
The time and labour associated with composting make it less attractive than other fertilizers. Another deterrent is that the process isn鈥檛 well understood, Buckley said.
鈥淭here isn鈥檛 a lot of science required Wholesale Soccer Hats ,鈥?she said. 鈥淧eople are somewhat intimidated because they think it requires a lot of monitoring. But you get a feel for it.鈥?p>
Composting may also have an image problem, as most Canadians likely associate compost with a box of rotting food waste in an urban backyard.
Even though it鈥檚 coupled to the green and organic movement, Dub茅 said most of the farmers in the compost co-operative are conventional producers.
鈥淭his is not about putting a label on things, it鈥檚 about sustainability,鈥?he said. 鈥淎nd it鈥檚 about economics as well. If you鈥檙e putting a product back on the land and if you鈥檙e saving energy in the process and if you鈥檙e also improving your soil, your bottom line is improved as well.鈥?p>
