Sustainable agriculture is a key resource in combatting climate change. I know it sounds far fetched, but think about it. Tilling causes contamination of runoff water, raising livestock releases greenhouse gases. Each stage of agricultural production has an environmental impact, and as we learn more about the environment, our treatment of agriculture must evolve.
This past summer, I experienced the progression of farming systems first hand as a research intern at the Rodale Institute. Rodale is a non-profit organization changing the face of agriculture through organic research and outreach. Centered in Kutztown, Pennsylvania, the Institute conducts experiments that revolutionizes organic, sustainable ag throughout the world.

The lesson Rodale taught me that resonated most was the role of soil in sustainability. Soil is quite literally the foundation of a farming system, and for that reason, its health is and should be the top priority of any agricultural operation.
Soil is not just dirt. Soil is naturally packed with microorganisms and nutrients which are vital in determining its ability to produce hearty crops. A healthy ratio of nitrogen, phosphorous and potassium within the soil determines a farm’s total productivity. Utilizing the harsh chemicals found in herbicides and pesticides can deplete these nutrients and minerals, damaging the overall integrity of the soil.
There are plenty of more sustainable alternatives to herbicides and pesticides. For example, cover crops can be utilized not only to restore nutrients in soil, but they can also help protect plants from weeds. Not only will cover crops do the same job as herbicides without harming the soil, but they may also help to suppress herbicide-resistant weeds. Cover crops may take some time investment, but they help build your soil health and therefore the sustainability of your farm in the long run.

So, what’s the point of ensuring soil health? The nutrients in soil will actually translate to nutrient density in the crop grown on that plot. In other words, healthier soil = healthier crops. Nutrient density is an extremely valuable agricultural commodity which is often times overlooked, but ensures the highest quality crop. Healthier crops make for a healthier life, for animals, for people and for the Earth.
My goal this year for the Student Farm at Penn State is to proliferate this dedication to soil health. Since the Student Farm is just beginning, starting with a quality foundation will ensure a sustainable and regenerative future. I look forward to seeing the growth the farm endures, rooted in healthy soil.
