Climate Farming

“Climate Farming” is a term I read about in Terra Preta, a book written by Ute Scheub. It means to grow food in a way that benefits our planet. We no longer need to think of agriculture as something that damages the environment through harmful practices involving chemicals and tractors. Instead “climate farming” means you will be growing good soil that will give back to the world endlessly. Your garden has the ability to make the177164110x world a better place.

Soil is made from sand, silt and clay. Your garden will have more or less of each of these 3 ingredients. Heavier soils mean more clay is present. Clay soils are stickier, and hold onto minerals in an abundant way. Sandy soils are lighter, more crumbly and hold on to fewer minerals. All soils can be amended by another ingredient; humus.

Humus is what is made in a compost pile, or right in your garden by worms and microbes. It is organic material that has been biodegraded until it looks dark and rich, it feels light and spongy and it smells fresh and earthy. Humus stimulates all of our senses in a delightful way, and with good reason, as we tend to be drawn to what is good for us. Humus helps retain moisture as well as soil structure in a garden, meaning that your plants also love it. Humus is full of microbes, since it is the microbes themselves that break down the organic matter to begin with, and microbes help feed your plants the nutrition that is stored in the soil. Without microbes, your plants could not survive.

img_3963Having high levels of humus in your garden, defined as greater than 2%, possibly even in the 10% arena, means that your garden has been turned into a carbon sink. What does this mean? It means that humus sequesters carbon from the atmosphere, eliminating greenhouse gasses from our environment. It turns out mother nature has a way around our careless polluting, and humus is her right hand man!

So what can you do to change your own yard into a carbon sink? Start making humus! Or, should I say, start allowing nature to make humus for you. This will benefit you, your garden and, it turns out, the whole world.

At the moment soil is disappearing 10 to 100 times faster than it is being made, as we are waging war on our soils. We kill the soil, reducing it to dirt and dust by applying chemical fertilizers, pesticides and herbicides. We then employ ploughs and tractors to rip up what’s left, destroying microbial habitat. By reducing soil (living and breathing matter) into dirt, we are killing off a quarter of the world’s species, which call soil their home, and we are rendering our fields useless. Dead dirt cannot support life, so food crops will not grow.

Let’s learn to employ those tiny farms hands, also known as microbes and worms, and encourage them to leave rich moisture-retaining humus behind. The microbes will thrive, our plants will thrive, our bodies will thrive (from eating mineral-rich foods) and our environment will thrive.

As Raoul Heinrich France said “Humus is made from life, by life, for life” so treat fallen leaves and grass clippings like a treasure bestowed upon us by the gods. Use them with good purpose, to nourish the Earth, and by default, our bodies.
