4-H Soil Health Project Ideas

Oklahoma and Texas now have Soil Health Achievement Awards for 4-H: a $1,200 scholarship will be given to a 4-H’er who has excelled in learning and teaching about soil health. The Soil Carbon Coalition and the Dixon Watershed Foundation pioneered these awards: Why? We know that soil health is key to agricultural productivity, clean water, food security, protection against flooding and drought, biodiversity, and human health. These are exactly the kinds of things that are important to 4-H clubs: and they offer wonderful opportunities to make a difference in the land, water, and community that surrounds you.

Does your 4-H club want to get involved?
Here are some of our project ideas, but we know you will

Learning Resources for Schools and Communities

Welcome! Our new learning resources include step-by-step instructions for facilitators to lead groups of participants through a series of activities to engage students, farmers, policy makers and others in seeing new possibilities related to soil health, water and carbon cycles, and systems-based land management. (Check back often as we are loading new ones every few days.) They are aligned with Next Generation Science Standards and Common Core State Standards for ease of use in U.S. schools, but can be used and adapted by anyone interested.

Remonitoring in California

This winter's remonitoring of California baseline carbon plots established in January-February 2011 showed most with little change, or slight losses. The highest gain was from a plot near Watsonville managed with holistic planned grazing by Joe Morris of TO Cattle Company ( which showed significant increases in all three layers sampled, with results viewable on the map of soil carbon change:

Atlas of Biological Work: a shared intelligence on landscape function

A short proposal for a fully featured Atlas of biological work (or Atlas of Land Work), an expansion of the Map of Soil Carbon Change. Some of the work on this is being funded by RSF Social Finance, the San Benito Community Foundation, and TomKat Ranch Educational Foundation.

You never change things by fighting the existing reality.
To change something, build a new model that makes the existing model obsolete.

Buckminster Fuller

If you want to make small changes, change how you do things.
If you want to make big changes, you must change how you see things.

Don Campbell

Life, powered by a mere thousandth of incoming sunlight, is the most powerful and creative planetary force. Our planet's atmosphere, its soils, its blue, white, and green colors viewed from space, even the composition of its crust and oceans, are the products of eons of

While we're on the subject of pyramids, Charley Orchard at has made a useful diagram of what makes monitoring valuable. Click the image to go to the May 2011 Land EKG newsletter explaining it.
