Making Compost 101

By 2022 apprentice Joshua Wright

Smelly, sticky, messy.

Perhaps these are some words to describe your experience with food waste. But it doesn't have to be! Enter the world of composting!

In permaculture we love composting and would never think about just throwing away our food scraps into the trash, because they aren’t waste, they are resources that will benefit our garden and our planet.

Composting is a great way of dealing with your kitchen scraps, autumn leaf litter and/or lawn trimmings, along with any other organic matter that may be in your garden. Dealing with a “waste” product and turning it into something beneficial. In permaculture we also call this stacking functions.

What is compost?

Compost is broken down, decomposed organic matter. It occurs naturally in the environment around us as living things decay. Through human interaction this natural process can be sped up.

Why should you be making compost?

Composting has several great benefits:

It improves soil health. Adding organic matter into soils allows them to better retain moisture leading to reduced irrigation costs. It lends itself to better aerated soils reducing the need to till and it provides habitat for beneficial fungi and micro-organisms to continue the work of decomposition and nutrient cycling.
It provides plants with nutrients essential for their growth. The main elements plants need are Nitrogen (N), Phosphorus (P) and Potassium (K), all of which are present in compost, along with a number of other elements in trace amounts such as Calcium (Ca), Magnesium (Mg), Iron (Fe) and Zinc (Zn).
Composting diverts waste from ending up in landfills and the incinerator. Both of these require lots of energy and resources to maintain and manage, so by composting you are freeing up time, money, and energy for better utilization elsewhere (building an abundant, regenerative future we can be proud of).
When in landfills food waste doesn’t have access to oxygen, becoming anaerobic. When decomposing in this airless environment it produces methane and carbon dioxide. When not in balance with natural cycles these gasses contributes to greenhouse gas overload in our atmosphere adding to our global climate crises.

In summary by composting not only are you doing less bad (by producing less pollution) you are actively doing good (building soil which is essential for a healthy planet)! Win, win!

So how do we go about getting started?

*Our little wigglers that we use for our vermicompost!*

First, let’s identify the best location: Ideally you will have a spot in your garden that is out of direct sun and protected from the rain. You will need something to contain the compost in. A wire cage or recycled wood pallet box will both work great. But you can use any containment method that is roughly 1m^3 and allows air to circulate. If you are limited in space or don’t have a yard, there are many great DIY options, such as a plastic bin with holes drilled out. Or check out vermicompost, which uses worms to help you out! Check out this blog article from Mother Jones to learn more about using worms to compost in a small space.
Next let’s look at what goes into your compost: We can break this down into two basic categories: "greens" and "browns". "Greens" are materials that contain higher quantities of nitrogen and "browns" contain higher quantities of carbon. Balancing this ratio of greens to browns is what will define the success of your compost operation.
This ideal ratio being 25-30 parts carbon to 1 part nitrogen.
Examples of “greens” are kitchen scraps or fresh lawn clippings. “Browns” can be dried leaves, wood chips, saw dust, etc.
Remembering that there is carbon in ALL organic material including materials that we classify as “green”, we can achieve our ideal ratio (25-30:1) by adding roughly 2 parts “brown” material to 1 part “green” material.
If your compost pile starts to smell, attract flies or is excessively wet add more browns, if it is too dry reduce that amount of brown material you add.
Your compost should have the same moisture content as that of a damp sponge. When squeezed firmly no more than a few drops should come out.

Excellent!

Armed with these basics outlined above you are ready to begin your journey into the underworld (soil).

Keep in mind that there is no teacher out there as good as direct experience so get your hands dirty and have fun with it.

One day, we too, shall be compost. And so closes the circle of life.

Improving Soils in the Humid Tropics of Costa Rica

In permaculture and agroforestry circles it’s common to hear the idea that we’re not growing plants so much as we’re cultivating rich, healthy soils in which plants will do their own growing.

Improving Soils in the Humid Tropics of Costa Rica

In permaculture and agroforestry circles it’s common to hear the idea that we’re not growing plants so much as we’re cultivating rich, healthy soils in which plants will do their own growing. Yet, to this end changing the make-up of soils seems like a daunting job. So how can we go about the task of improving our soils in a simple and efficient way that corresponds with permaculture principles?

The challenge of Tropical Soils

Soils in humid Tropical America are generally found to be eroded and leached. In this region’s ecosystems, about 85% of nutrients are held in plants and animals, so the soils themselves are infertile. Only terraces, floodplains, and new volcanoes keep some soil fertility replenished if land is cultivated (Mollison, 2004). This yields soils that are high in clay content, poor in nutrient content, and often quite acidic. As we say here at the Rancho Mastatal, a permaculture farm in Costa Rica, it’s soil that’s great for natural building, yet not ideal for growing an abundance of food.

The goal with soils like ours is to improve soil texture, increase mineral and nutrient content, reduce soil acidity, enrich microbial life, and increase the quantity of organic matter held in the soil.

Permaculture & Agroforestry based strategies

In a recent agroforestry workshop held at the Rancho Mastatal here in Costa Rica, a class that worked through concepts of a multi-strata, diverse style of permaculture, the holy trinity of soil amendments for the humid tropics was revealed. The three pillars of improving cultivated soils are

Biomass
The strategy of biomass organized on contour (lines running perpendicular to the direction of the cultivated slope) is the most visible method used here at Rancho Mastatal to improve the soil’s structure and nutritional/mineral content, our ‘organic’ way of applying fertilizer. In the humid tropics, biomass tends to be available in great quantity, and can be used to build up the mentioned contours. Over time these will build to form terraces that greatly reduce soil loss related to erosion and leaching.
Mountain Microorganisms
Mountain microorganisms is a world of its own. Through the fermentation of leaf litter from nearby forests, we cultivate microorganisms which are then applied to our soils, the foliage of our plants, and our compost. We are reproducing healthy bacteria and yeast that, when used in our permaculture systems, will in turn help our plants absorb more nutritional benefit from our soils. To read in more depth about how to make Mountain Microorganisms read this article.
Biochar
Biochar will then provide a long-lasting refuge for these beneficial microorganisms. This is due to its incredibly high surface area within its structure. This special form of charcoal is extremely slow to break down and both directly provides nutrients and minerals to our soils as well as creating a positive feedback loop of topsoil production.

Many ways to develop tropical soils

There are other solid permaculture concepts for improving soils in the humid tropics that should be mentioned here. To deal with highly acidic soils, adding lime at regular temporal intervals is a useful strategy. We tend to avoid planting annuals while opting for perennials, by which we disturb the soil less and reduce potential erosion. Read our article about which perennial greens do well in the tropics here. Over time these plants will help build humus and topsoil. There are plenty of pro tips from the world of permaculture that you’ll find helpful, like adding shredded cane and bamboo species as a mulch for silica and calcium enrichment. This will in turn help to raise pH levels (lower acidity) of soils and reduce leaching and erosion. We add Humanure and effluent from our Biodigestors, this helps build our soil and use commonly wasted products to grow food!
