Soil Health Program

Why are soils important?

Soil helps recycle nutrients which makes them available to plants. Microbes found in soil help break down organic matter into essential nutrients such as carbon, nitrogen, phosphorus, potassium among others which are essential to plant growth.

Provides habitat for billions of organisms, contributing to biodiversity and creating healthy organic matter. A single tablespoon of healthy soil can contain over 50 billion microbes encompassing about 10,000 individual species.

Supplies a large amount of the antibiotics used to fight diseases. The most famous example of this is Alexander Fleming’s discovery of Penicillin which revolutionized medicine and saved millions of lives.

Why should we care?

Soil is an extremely important resource for humans, animals, fungus, and plants alike. It is estimated that 95% of our food is either directly or indirectly reliant upon soil. Soils maintain biodiversity for millions of species, and help sequester carbon. It can help improve water quality by reducing the amount of sediments and nutrients that enter streams. Water can be cooled and stored in soils during times of flooding or precipitation and re-released during dryer periods. Healthy soils are often times taken for granted, but through education, collaboration, and good agricultural techniques we can ensure the health of our soil and all the benefits that it provides.

Unhealthy soil can result in agricultural, ecological, cultural, and environmental issues. Over the course of the last century many agricultural soils around the world have lost 40-60% of their organic carbon. A common issue found locally in Columbia County is declining pH rates that can cause reduced yields, decreased water quality, decreased biodiversity, and other potential and significant impacts. The Columbia Conservation District (CCD) is working with landowners to better understand why this is happening, to recognize the impacts, and to explore different approaches to help improve soil health.


CCD has been working alongside partners from WSU Extension, to investigate the problems, evaluate solutions, implement opportunities, and adapt to the outcomes. The Soil pH and Nutrients project began in 2013, with roughly 30 landowners involved in applying lime to the fields.

After a 5 year study, observations led us to understand that the amounts initially applied were not enough. After more research, a sub-project emerged, which included looking at the soil from a more wholistic manner utilizing the Kinsey Agricultural Services, to apply not only lime but any Macro and Micro-nutrients needed to balance the soil from all sides. This project is currently on a field separate from the initial project fields, is roughly 60 acres in size and is located 5 minutes outside of Dayton in the heartland of the foothills to the Blues Mountains.

CCD, along with partners, are hopeful in providing the data necessary to combat the current and future issues within the soil.

Together we can realize the solutions towards sustaining fruitful soils and preserving the balance of nature.
