Sustainable Manure, Land Raped Peat Moss<\/strong><\/p>\n

I find it heartbreaking to see well-meaning people buying bales of peat moss. Old-think gardening promoted peat moss heavily, but all forms of sphagnum peat moss are harvested by destroying boggy natural habitats. Worst of all, this is truly senseless destruction, because peat moss isn\u2019t helpful for our soil or plants.<\/p>\n

What??? Yup!!! For starters, peat moss is very low in nutrients and it degrades too quickly to be an effective soil conditioner. In addition, it\u2019s so acidic that it can kill bacteria, which is why sphagnum moss was used as bandaging material for centuries (maybe millennia). Wounds packed with clean sphagnum moss had a better chance of healing cleanly, and it was still used for British troops during WWII.<\/p>\n

Peat Moss Damage And Dangers<\/strong><\/p>\n

Besides all that, peat moss makes a horrible top dressing. Top dressing is the final layer of a garden bed, usually consisting of an inch or two of fine textured mulch such as compost or aged dairy manure. This layer conserves moisture, suppresses weeds, and promotes rapid root growth. Though often recommended, peat moss also makes a remarkably poor mulch, drying to an impervious, water-shedding (rather than water-conserving) mat in no time. Once dried out, peat is very difficult to rewet in garden soils and in peat based potting mixes, which is annoying and very hard on plants. Peat based potting mixes are light in weight, which is good if you are carrying the pots around, but also means wind can rock plants easily, distressing the roots.<\/p>\n

Though fresh peat is highly acidic, when dried and baled, it can harbor spores of fungal diseases that can be dangerous to handlers. Nursery workers are warned by law to wear double gloves and micron filtration masks when handling peat moss. The gardener is not told anything, yet those who use peat moss regularly are at risk for fungal pneumonias and other illnesses.<\/p>\n

Sustainable And Not So Sustainable<\/strong><\/p>\n

Finally, peat moss is not a renewable resource except in glacial terms. If you visit bogs that have been harvested for many years, you can see plainly that cuts made a century ago have barely begun to heal. Bogs are delicate, intricate environments that host hundreds of living fauna and flora. When bogs are destroyed by peat mining, companies are now forced to \u201crestore\u201d them, but the artificial, \u201cmanaged\u201d bogs never achieve the biodiversity of the original habitat. I\u2019m not alone in this anti-peat campaign; Here\u2019s a link to Ken Druse\u2019s article on peat moss: http:\/\/gardenrant.com\/2009\/04\/ken-druse-dishes-the-dirt-about-peat-moss.html<\/strong><\/p>\n

If peat is not a truly renewable resource, manures definitely are. One thing we can count on is that poop happens. However, it does matter which manure we choose. Initial testing of various kinds of animal manures at Oregon State University in Corvallis show that animal manures vary widely in their qualities. Horse manure, for example, is often contaminated with worming agents that continue to kill worms in compost and soil after passing through the horse. Horse manure mixed with bedding may contain clopyralid, a long-lasting pesticide that remains active indefinitely (it especially affects legumes, nightshades, and composites, which covers a lot of floral ground).<\/p>\n

Washed Or Digested?<\/strong><\/p>\n

In stark contrast, aged dairy manure makes an excellent soil amendment and\/or top dressing. Recent research indicates that a mulch of dairy manure can slow down or even halt the growth of certain soil pathogens, notably several root rots that are prevalent in the native soils of the Northwest. Most modern dairies have holding pits where manure is stored. The barns are washed down daily and the manure accumulates in the holding pits. The nitrogen-rich effluent is drawn off and returned to the fields where alfalfa and other fodder is grown. The washed manure is sold as a splendid soil amendment. Dairy manure from an organic dairy will not contain bovine growth hormone, steroids, or other \u201cprophylactic\u201d medications.<\/p>\n

Digested cow manure is what\u2019s left over after manure is mined for energy. Dairy manure solids (often mixed with field crop waste) are trucked to an anaerobic digester facility, where the methane is stripped out and converted to electricity, which gets sold to local power companies, partly offsetting trucking costs. Anaerobic digestion produces biogas (mainly methane and carbon dioxide) by composting organic materials in an oxygen-free environment. When manure breaks down outside, the biogas becomes a \u2018greenhouse gas\u2019, but when it\u2019s captured in an anaerobic digester, the result is clean power and a big pile of digested poo. It\u2019s not exactly like aged, composted manure, but it has similar nutrient levels, low pathogen levels, and is an excellent soil conditioner. Because it is not as aged, it does smell more ripe, as holiday visitors to my home have noted.<\/p>\n

True Power Of Poop<\/strong><\/p>\n

Anaerobic digesters are hardly new, but today\u2019s technology makes them far more efficient. In Washington State, dairy coops share local digesters to create energy and manage their mounds of manure. It took time to figure out how to get that end product into gardens, but today, you can buy it as bags of Magic Dirt, USDA certified, biobased potting soil that has been approved for organic growers by the Idaho Department of Agriculture.<\/p>\n
