Nutrients are essential for us to grow food, feed, fuel, and fiber. But what happens when there's too much of a good thing?
From driving a car to buying groceries, many parts of our daily lives make up our carbon footprint. And the scope gets even bigger when you consider the carbon footprint of a whole organization.
We'd love to say it's possible to completely cut greenhouse gas emissions. But industries like transportation and manufacturing will always produce some amount of greenhouse gases. Offsets are one way to help.
Back in 2007, Alberta (one of Canada's 13 provinces) instituted new regulations to curb greenhouse gas emissions, including a carbon market. So how did it go?

When we talk about carbon markets, "additionality" is one of those terms that's tough to avoid. But what is additionality? And what does it mean when it comes to agricultural carbon?
The "gold standard" of soil sampling is getting physical samples from multiple spots throughout the field. But all that could be changing--watch Steven Hall explain why.
Decarbonization is the push to hit "net zero" or "carbon neutral" emissions. But what does all that have to do with agriculture?
“Additionality” is a huge component of verifying whether a carbon market is creating quality credits. It’s asking, “Is this project sequestering carbon or decreasing emissions in a way that would not happen otherwise?”
Adverse weather and extreme climatic events can hinder storage or even release large amounts of soil carbon.
Total soil carbon includes both organic and inorganic carbon. Soil organic carbon includes the once-living matter from plants, dead leaves, roots, and soil microbes, while inorganic carbon is mineral-based and much less responsive to management.
Owned, direct, indirect, energy, supply chains--what in the world counts as an emission for each scope?
New technologies could be the next big step in helping agricultural and environmental service markets gain ground. But how? And which technologies will be most helpful?
Measuring, reporting, and verifying soil carbon requires accurate collection of soil data, reporting in standardized units, and third-party checks.
After adding additional plant matter to the soil, the biggest driver of storing soil organic carbon is the activity of microorganisms like bacteria and fungi, followed by soil texture.
Cover crops provide an additional source of biomass to the soil. More biomass means more opportunities to sequester carbon!
Brazil, European countries, and the United States are among those focusing on agriculture’s role in reducing greenhouse gas emissions and sequestering carbon.
Potential buyers of carbon and ecosystem service credits include any business, government, industry, or individual interested in decreasing greenhouse gas (GHG) emissions.
Both voluntary and compliance carbon markets are trying to do the same thing--generate and sell credible carbon credits. But key differences arise when buyers and sellers opt in compared to mandated systems.
Integrated Pest management (IPM) is a strategy to manage pest and disease threats to your crops. But it could have bigger benefits—it’s also an important part of your toolkit to improve crop resilience in the face of extreme weather events and changing conditions.
Temperature, rainfall, weather, pests, disease—there are lots of circumstances that can negatively impact your crops. But seed treatments are one tool in your toolkit to improve crop resilience.
When a host plant, virulent pathogen, and favorable environment are all in the same place at the same time, diseases can pop up. And nothing is worse than losing healthy plants to disease. Luckily, there are ways you can reduce disease pressure on your crops.
Collect samples to measure organic carbon concentration, bulk density, and coarse fragments. Together, these three measures can help you accurately calculate soil carbon stock in your fields.
Calculating soil organic carbon stock requires measures of soil organic carbon concentration of the soil, bulk density, and coarse fragment content.
A “carbon pool” is any part of the climate system with the capacity to store, accumulate, or release carbon, according to the European Union. The soil carbon pool includes all the carbon in the soil, but the size of the soil carbon pool can be changed depending on management.

139 million acres of farmland in the US are still eligible to change crop production practices to reduce tillage, according to United States Department of Agriculture data from 2016.
Carbon credits in voluntary carbon markets are typically priced and sold by the market providers themselves. Like other consumer goods, prices for credits are influenced by supply and demand. As demand increases, so too could the average price paid per credit sold on the marketplace.
Agricultural soils hold great potential for sequestering carbon and improving soil health in the process. But how do you measure soil carbon?
Climate-smart agriculture relies on coordinating a complex suite of agricultural practices to provide ecosystem services, but measurement of these benefits is scattered. A national ecosystem services monitoring network could help.
The soil’s potential carbon capacity depends on soil type, climate, and management practices. No two soils will sequester carbon at the same rate or in exactly the same amount—different producers need to implement different practices depending on their land.
Increased soil water storage, improved biological activity, better soil aggregation, improved yield--these are just a few of the benefits of increasing agricultural soil carbon.
Carbon cycles through agricultural systems through plant photosynthesis, biomass decomposition, and animal production, with opportunities to improve carbon sequestration at each point in the cycle.
Management practices either improve or set back soil carbon sequestration, beginning with the soil and moving through crop production.
Sinking carbon into soil is a powerful tool in our toolbox to decrease or offset carbon emissions. But how does carbon get into the soil? And once it's there, how do we keep it there?
All aspects of crop production that involve keeping the soil covered, minimizing disturbance, and agronomic management can help sequester carbon and reduce emissions.
A carbon registry is the central component of a carbon market trade, positioned between projects that store or offset carbon and buyers that purchase carbon credits.
Compared to other sectors globally, food production (including retail, transport, processing, farming, and land use) accounts for 26% of all greenhouse gas emissions as of 2019.
Soil management is responsible for over half the greenhouse gas emissions generated by agriculture in the United States. Enteric fermentation—or gases created by livestock digesting their food—account for another 27%, and manure management another 14%.
