The foundation of life on earth

Soils Sustain Ecosystems

Soil is one of our most important natural resources, playing an integral role in supporting the health of our planet.

Nutrient-rich soils sustain ecosystems and nourish humans in many different ways — filtering water, cycling nutrients, facilitating agriculture, storing carbon, and mitigating the effects of climate change.

Soil and Carbon

As the largest land-based pool of carbon, soil is essential for maintaining the global carbon cycle. In fact, soil stores more carbon than all of the world’s forests combined.

When soil degrades through natural and artificial processes, like erosion and overuse of fertilizers, it not only has the potential to reduce crop yields — it also releases emissions of carbon and other greenhouse gases into the atmosphere.

By supporting the well-being of soils, we can help regulate the earth’s climate and mitigate the effects of global warming.

How We Enhance Soil Quality

Organic Matter

By adding manure, compost, mulch, or plant residues, we can increase organic matter to cultivate larger, more diverse microbial populations in soils.

Cover Crops

By planting cover crops on farms, we can control topsoil erosion, regulate moisture, and reduce extreme temperature fluctuations to improve soil quality.

Crop Rotation

By rotating crops on agricultural land — especially legumes — we can help break pest and disease cycles and increase organic matter in soil.

Minimal Soil Disturbance

Moving away from intensive tillage towards low- or no-till systems enables farmers to maintain soil structure and protect soil organisms.

Partnering From The Ground Up

At PUR, we enable companies to reduce their carbon footprint by evolving their operations at the ground level — achieving ambitious ecological goals by improving soil quality on farms worldwide.

PUR’s technicians conduct on-site visits to assess and monitor soil health, developing long-term plans for sustainable food production and ecosystem services such as carbon storage.

Evolving Global Frameworks

PUR works with international stakeholders to apply the best practices and proper evaluation criteria associated with regenerative agriculture.

By adopting a holistic definition for insetting, we implement programs that incorporate the most robust global standards and evolving frameworks for nature-based solutions.

As a result, PUR is able to support our partners in the diverse reporting requirements for valuing and communicating their project outcomes.


At PUR, we empower companies to take responsibility for the impacts of their supply chains — implementing innovative agricultural programs that achieve ambitious ecological goals.
