  25. 25. Compost can play an important role in all these effortsComposted livestock waste is a value added product that: •Reduces agricultural nutrient losses, •Improves soil water retention, •Reduces soil erosion, •Improves plant growth (even during drought), •Can be used as a bio-filter, •Captures atmospheric carbon and nitrogen in the soil, and •Meets environmental standards for waterway reclamation. ©2008 Rodale institute
  26. 26. Compost basics Compost is “the controlled decomposition of organic residues into a humus-like end product.” 25:1 / 40:1 mix of “brown” (C-based) materials and “green” (N-based) materials 50-65% moisture Temperatures 131 - 170°F or more during active decomposition (15 Days) Made in windrows, piles or containers (large or small) Usually requires repeated mixing (5 times in 15 days) Takes 8 weeks to 2 years (depending on the above factors) ©2008 Rodale institute

  34. 34. EPA 2009 StatisticsThe amount of food wasted in the US is staggering. The USgenerates more than 34 million tons of food waste each year.Paper is the only material category where we generate morewaste, but we also recycle more. Food waste is more than 14percent of the total municipal solid waste stream. Less than threepercent of the 34 million tons of food waste generated in 2009was recovered and recycled. The rest —33 million tons— wasthrown away. Food waste now represents the single largestcomponent of MSW reaching landfills and incinerators. ©2008 Rodale institute
  35. 35. World Food Waste Study By Jonathan|Bloom Published: May 12, 2011UN’s Food and Agriculture Organization released a very interesting report on global food waste. It contains mind-boggling new statistics, calls international attention to the issue and serves as a prelude to the SaveFood! conference in Germany. Here’s the key line: Roughly one third of the food produced in the world for human consumption every year — approximately 1.3 billion tonnes — gets lost or wasted… ©2008 Rodale institute

  54. 54. Compost application guidelines to protect water quality• Test the compost to find out its NPK ratio• Apply the right amount of N to feed your crop• Be careful not to over-apply P• Think of compost as a soil amendment (microbe food) more than as a fertilizer ©2008 Rodale institute
  55. 55. Soil in Organic Systems • Higher corn and soybean yields in drought years • Increased soil C and N• Higher water infiltration• Higher water holding cap.• Higher microbial activity ©2008 Rodale institute
