Composting as a Radical Act

To provide your gardens with life-giving nitrogen, forget about buying chemical fertilizers. There are endless composting options that will allow you to give your plants all the nourishment they need—without the nasty effects of chemical runoff choking the life out of estuaries, streams, and rivers.

Yesterday's explosion at a fertilizer plant in Texas is akin to devastation wrought by pipes bursting during oil extraction or the disastrous side effects of fracking. In our manic attempts to artificially grow super-crops, live in unnecessary luxury, and pay more heed to money than common sense, we're causing untold damage to the Earth's ecosystems—and, inevitably, to ourselves. Anytime we pack hundreds of tons of ammonium nitrate into a factory to make chemical fertilizer, we're putting lives at risk. Anytime we run pipelines to transfer oil, we're risking the health and well-being of animals, crops, and people.

But let's get off the soapbox and spend a few minutes exploring ways to take matters into our own hands.

Growing your own food removes your need for Big Agriculture. By creating your own beds of greens, veggies, and even fruit trees, you're taking yourself out of the monster machine that large-scale agriculture's become. So if you're making that move, why not ensure that in your small microcosm, the run-off from your backyard isn't going to contribute to any pollution or sickening runoff?

It's easy. We promise.

First, let's consider the two biggest culprits of unhealthy backyard gardening: pesticides and fertilizers. 

Pesticides

The EPA estimates that approximately 74 million pounds of pesticide active ingredients (7 percent of total conventional pesticide use in the United States) are used in homes and gardens each year. Pesticides are either applied by commercial pest control and landscape maintenance companies or by homeowners themselves. Studies have shown that pesticides can be extremely unsafe, particularly when they run off into waterways, which can cause short- and long-term damage to people and the environment. Pesticides can also inadvertently kill living things that they are not intended to. As a whole, pesticides do provide some benefits, but they are also known to harm the environment and the plants and animals that it contains. When a pesticide leaches through the soil where it is applied, it can end up in the water table. In waterways, millions of fish are killed by pesticides each year, and other aquatic life also suffers the consequences of pesticide-contaminated water. Pesticides are also known to add to air pollution as a result of pesticide drift, and some even play a role in harming the ozone layer and contributing to global warming. Additionally, pesticides have a resistance to breaking down over time, meaning that their effects can continue over a long period of time.

Fertilizers

Chemical fertilizers promote quick growth in plants, which can prevent them from developing a good root growth, strong stems, or nutritious fruits and vegetables. Plants will sprout quickly, but what you'll end up with will not be worth much. Chemical fertilizer is usually high in nitrogen salts, and if the nitrogen is absorbed by soil too quickly, it will end up dehydrating the plant, causing it to dry up and die.

Chemicals in man-made fertilizers will harm and eventually kill the natural microbes found in your soil. These include beneficial insects, fungus, and bacteria naturally found in your soil. These "creatures" are all naturally occurring and necessary for healthy soil and plant growth. Obviously applying chemicals to your plants and soil will affect these organisms. Chemicals in synthetic fertilizers will eventually, and unavoidably, end up leaking into our environment's water supply. It will be consumed by wildlife and can have short- and long-term effects on them—just like it would if we were to ingest these chemicals. Finally, let's think about the fact that we are going to eat these plants. If we are saturating the soil they grow in with chemicals, and then feeding the plants and treating them with chemicals (pesticides, herbicides, fungicides), how can we possibly think these fruits and vegetables are healthy for us to eat? What is the point of growing our own food if we're just going to poison it before eating it?

Composting as a Radical Act

Consider growing your own food your civic duty, and composting as your radical act. Done properly, you'll be creating your own closed-loop system that flies in the face of Big Ag. All you'll need to start a basic compost set-up are a small container in your kitchen to catch your food scraps, and a larger bin outside to store them.

(Note: If you're in a city and/or don't have a yard, vermicompost is the way to go. You'll just need a large tupperware container under your sink to hold the worms. Done right, we promise that your guests—and pests like bugs/rats/mice—will never know the worms and food scraps are there!

First, let's go over the basics of compost. Here's a briefing on the carbon-to-nitrogen ratio, gleaned from LawnLove.com:

The optimal ratio of carbon (C) to nitrogen (N) (brown to green) is about 30:1. So, what does this mean for you as a home composter? It means you’ll need lots of brown with a little bit of green thrown in. If you have deciduous trees, you’ll likely produce much more leaf litter (brown) than kitchen waste (green), which provides an ideal balance. If your ratio is a little off, don’t worry. Your pile may take a little longer to break down, though.

Estimated Carbon-to-Nitrogen Ratios

Browns = High Carbon

C:N

  • Ashes, wood—25:1

  • Cardboard, shredded—350:1

  • Corn stalks—75:1

  • Fruit waste—35:1

  • Leaves—60:1

  • Newspaper, shredded—175:1

  • Peanut shells—35:1

  • Pine needles—80:1

  • Sawdust—325:1

  • Straw—75:1

  • Wood chips—400:1

Greens = High Nitrogen

C:N

  • Alfalfa—12:1

  • Clover—23:1

  • Coffee grounds—20:1

  • Food waste—20:1

  • Garden waste—30:1

  • Grass clippings—20:1

  • Hay—25:1

  • Manures—15:1

  • Seaweed—19:1

  • Vegetable scraps—25:1

  • Weeds—30:1

Note: Many ingredients used for composting do not have the ideal ratio of 25-30:1. As a result, most must be mixed to create "

High C:N ratios may be lowered by adding grass clippings or manures. Low C:N ratios may be raised by adding paper, dry leaves or wood chips.

Your Very Own Compost Bin

Your compost is going to act as a wonderful fertilizer for your plants. That, used in tandem with crop rotation and natural bug deterrents (and attractants!) will ensure a healthy garden for years to come.

For in Your Kitchen

The most popular compost bins for inside come in plastic, ceramic, or metal. They generally have a charcoal filter to keep the food scraps aerated without smelling. You can also make your own (click here for instructions), or use a sturdy snap-lock tupperware container that you empty out every day or so and rinse well. Here are a few images of standard kitchen compost containers:

For Your Yard

Backyard compost can come in a heap, a bin, a barrel, a pallet cube, or can simply be put directly onto your garden beds (as we often do in our mulch gardens). Some of the most popular outdoor compost tumblers are plastic, which causes some concern for those concerned about toxins leeching out of the plastic as the compost heats up inside. There are no conclusive tests on the subject thus far—probably in part because compost doesn't get hotter than about 160 degrees—but for those of you who are weary, there are plenty of other options besides those plastic tumblers.

Wooden compost bins are readily available online (click here for some examples), but for significantly less you can make your own (check out these directives from Instructables). And for those of you out in the country, a simple wire-mesh enclosure will do the trick (to turn your compost every few months, just rake out the pile, move your stakes, and shovel out the black earth at the bottom). But you can also use old bureaus, old fencing, or any other design you can dream up. Most important is that you're able to turn the food scraps, and that they receive ample amount of aeration for good decomposition.
