Composting: Hitting Paydirt
Compost happens… but it happens a whole lot faster when you know how!
I’m a big fan of composting because it really helps the soil and it helps me recycle household waste and turn it into something useful. Compost improves soil tilth; helps maintain a neutral pH, and allows the soil to hold more nutrients and water (it can literally quadruple the soil’s ability to store water). Compost is to your garden what spinach is to Popeye. Finally, compost feeds earthworms and microbial life in the soil — which, in turn, support your plants. It doesn’t matter what kind of soil you have. All soils can be improved with the addition of compost.
With the right equipment, turning garbage into garden gold is a cinch! At Planet Natural we supply everything you need: bins, tumblers and activators to get your pile cooking, plus compost turners to aerate your heap. Now, let’s rot!
You can compost almost all the organic matter from your household including garden cuttings, vegetable peelings and even eggshells. Any meat scraps or dairy products are a no-no. These attract rodents and can stink up your pile. Tea leaves and coffee grounds are great additions because they contain caffeine, a natural herbicide. For complete instructions on how to make compost see our composting guide.
In terms of how much compost your garden will need, it depends on soil health as well as the length of your gardening season and the amount of rain your area receives. The longer the growing season, the more compost you will need. Also in rainy climates more of the compost’s nutrients will wash away during rains, so plan accordingly.
Building a Compost Pile
Composting involves mixing kitchen, yard and garden waste in a pile and providing conditions that encourage decomposition. The composting process is fueled by all kinds of microscopic organisms (bacteria, fungi) that take up residence inside your compost pile, continuously devouring and recycling it to produce a valuable soil amendment and rich organic fertilizer.
Sound complicated? It’s really not. All you need to know are a few basic guidelines to keep your pile cooking.
Size. Make your pile at least 3′ x 3′ x 3′ – smaller piles may not heat properly and larger piles can become unmanageable and hard to turn. Learn more at Cornell Universities page.
Moisture. For best results, the moisture content of a compost pile should be between 40 and 60 percent. In other words, your pile should be moist, but not sopping wet.
How hot is your pile? The REOTEMP® Compost Thermometer is ideally suited for measuring the core temperature of a bin or pile. Measures temperatures up to 200°F and includes three temperature zones to help keep your pile cooking!
Oxygen. Keep your pile aerated by turning the pile – oxygen keeps the microbes that break down your compost happy. Use a pitch fork, spade or compost turner to mix the pile often. Don’t aerate your compost and it will break down slowly.
Ingredients. Make sure to include carbon-rich “brown” materials like leaves, straw and sawdust and nitrogen-rich “green” materials like grass clippings, vegetable peelings and manures (no pet droppings). When adding ingredients to your compost pile, try to mix a ratio of three parts brown materials to one part green. A well-balanced “diet” will ensure that composting doesn’t take too long and that you don’t end up with a slimy, smelly heap.
Once you have achieved finished compost, you can add it to your garden any time of year without the fear of burning plants or polluting water. For best results, add compost at least two to four weeks before you plant. That will give it time to work its magic and integrate with your soil. Try to work the compost in at least six to eight inches deep and shoot for a ratio of compost to soil of about half to half. Also, consider “side-dressing” your rapidly growing plants with this “garden gold” during the late spring or early summer. Place the compost at the side of the plants and gently incorporate it into the soil. Keep the compost about an inch away from the stem of the plant.
Another way to get compost into your soil is by brewing compost tea. (Just don’t try drinking it yourself. Ick.) Make compost tea by mixing equal parts of compost and water and let it sit. Pour the resulting “tea” directly onto the soil around your plants. If you’re going to use it on smaller seedlings dilute it to four parts of water to one part compost. What’s great about compost tea, is that you can just pour it on and you don’t have to spend time working it into the soil. The downside is that since you’re adding water, the compost is diluted. (If you don’t feel like brewing your own batch, there are commercial teas that you can buy.)
Compost & Manure Rules for Organic Production
The National Organic Standard is very explicit about compost making. Compost piles must maintain a temperature between 131 and 170° F. for at least three days in a static or enclosed vessel system, or at least 15 days in a windrow system, with at least five turnings. Unless these criteria are met, the resulting product is not — in the eyes of the (NOP) — considered compost. Rather, it is simply a pile of raw materials. If one of those raw materials is manure, it can make a big difference in how it may be used in crop production. Raw livestock manure can carry pathogens that pose a danger to human health. The principal reason behind the NOP-approved process for composting, is to prevent possible food contamination with these organisms. Maintaining high temperatures in the compost pile kills off most microorganisms that are pathogenic to humans, and the resulting material is believed safe to use on crops at any stage up through harvest. Heat-treated, dried and other processed manures, and manure that has not been composted according to NOP specifications, may still be used in organic crop production. However, it must be applied as if it were raw manure. According to the NOP’s rules, raw manure:
- can be applied at will to crops not intended for human consumption
- cannot be applied to a crop within 120 days of harvest if the edible portion has direct soil contact
- cannot be applied to a crop within 90 days of harvest when the edible portion does not have soil contact
We believe that these restrictions will be strictly enforced. Among the growers most at risk of manure rule violations are those that use organic media for direct greenhouse production of salad greens, edible flowers and baby vegetables, because the time from seeding to harvest is brief. This specialty market is a significant one for many organic producers, and serious errors can result in a loss of certification, bad publicity and even endangerment of public health.
