  • Celebrating Soil

    This is California Healthy Soils Week, and today is Food Waste and Compost Day. The thin layer of carbon, minerals and microorganisms known as soil provides the basis for life on this planet as we know it, so it is worth celebrating.

    Worldwide, cultivated soils have lost between 50 and 80 percent of their soil carbon. Carbon is the stuff that makes soil look rich and black. In California, we have agricultural soils with critically low soil carbon. Tilling exposes soil carbon to the air, allowing it to vaporize as carbon dioxide. Millions of tons of previously soil-based carbon have moved to the atmosphere, contributing to our global climate problem. Carbon in the soil feeds underground microbial life, a critical component of soil health. High-carbon, high-microbe soils grow healthy, resilient crops that need less water and fertilizer.

    Soil can absorb millions of tons of carbon dioxide from the air worldwide. Building soil carbon is possibly the most effective way to slow and even reverse a changing climate.

    How do we build soil carbon? The fastest and easiest way is by using compost and mulch. The California compost community takes millions of tons of lawn trimmings and food waste annually and transforms these discards into valuable mulches and soil amendments. You can help by putting only clean, biodegradable organics in your “green” bin (if your waste management service provides one), and by purchasing compost and mulch for your yard. You can also compost at home.

    Compost contains about 22 percent carbon, and it also provides a diverse community of micro-organisms. Plants that grow in soil with a diverse and robust microbial life will be bigger and stronger, and will pull more carbon out of the air for photosynthesis. But plants do not use all of the carbon they sequester from the air. They pump some of it into the ground through their roots, attracting friendly soil organisms and growing the carbon pool again.

    Once we understand the environmental power of soil, it makes sense to have a week to celebrate it. In 2015, we celebrated the International Year of the Soil … and 2016 was the International Year of the Pulses.

    A pulse is a legume that produces a dry grain, not a green vegetable. If you are experiencing dwindling yields in your backyard garden, consider using compost and planting a cover crop that includes pulses. A cover crop helps keep roots in the soil at all time, which feeds soil microorganisms. It also protects the soil surface from sun and erosion. When cover crops are cut down, the roots become part of the soil carbon pool. Legumes also take nitrogen out of the air (our atmosphere is about 78 percent nitrogen) and “fix” it into the soil. Some cover crops can fix as much as 200 pounds per acre of nitrogen into soil, helping to fuel next year’s crops.

    It’s time to give the soil the respect and protection it deserves. Compost, mulch, and cover crops are sustainable ways to build healthy soils and help prepare for whatever Mother Nature throws at us next.

  • Thoughtful Giving

    If you follow CalRecycle on Twitter or Facebook, you know we are big into experience gifts like a miniature golf night, a day at the zoo, or dinner at a nice restaurant, rather than material gifts that may ultimately end up in a landfill. Shopping season is well underway now, and we know it’s easy to get caught up in those exciting sales, so we thought we’d leave you with this article and video from the Washington Post—and again suggest giving the gift of quality time and fond memories this holiday season.
