6 Ways to Cut Back on Greenhouse Gas while Cutting Your Grass

Lawns are everywhere--I bet you have one! Turfgrass, like all other plants, requires nutrients. And nitrogen fertilizers, lawn mowing, and other maintenance tasks can give off powerful greenhouse gases. Read on to learn how to cut greenhouse gas emissions from turfgrass systems.

Can Plant Breeding Help Store More Soil Carbon?

Plant breeders have made incredible improvements to crops, from improving yield to boosting resilience and increasing pest resistance. But can plant breeding improve soil carbon storage?

article
What Is a Carbon Footprint?

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.

Taking Nitrous Oxide Samples In The Field

Nitrous oxide is a greenhouse gas with 300 times the global warming potential of carbon dioxide. How do we measure it in the field, and what can we do to cut emissions?

article
How Deep Is Organic Carbon Stored in the Soil?

Changing management practices can help sequester carbon in the soil and improve overall soil health. But how deep does that organic carbon go?

video
How Is Soil Sampling Changing?

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.

article
How Does Weather Impact Soil Carbon Storage?

Adverse weather and extreme climatic events can hinder storage or even release large amounts of soil carbon.

article
What’s the Difference Between Total Soil Carbon & Soil Organic 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.

article
What Are Scope 1, 2, and 3 Emissions?

Owned, direct, indirect, energy, supply chains--what in the world counts as an emission for each scope?

article
How Is Soil Carbon Measured, Reported, and Verified?

Measuring, reporting, and verifying soil carbon requires accurate collection of soil data, reporting in standardized units, and third-party checks.

article
What Are the Drivers of Soil Organic Carbon Storage?

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.

How To Take Manual Soil Cores for Soil Carbon Measurement

Interested in finding out how much carbon is in your soil? One of the first things to tackle is taking manual soil cores.

article
How Should You Collect Soil Samples to Calculate Carbon Stock?

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.

article
How Do You Calculate Soil Carbon Stock?

Calculating soil organic carbon stock requires measures of soil organic carbon concentration of the soil, bulk density, and coarse fragment content.

article
What Is the Soil Carbon Pool?

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.

podcast
What Are the Challenges for Measuring, Reporting, and Verifying Soil Carbon?

Carbon markets rely on accurate measurement, reporting, and verification (MRV) of soil carbon to issue carbon credits. But tallying soil carbon can be tricky. How should we go about sampling soil for MRV? And what does it tell us?

article
What Is Agriculture’s Role in Global Greenhouse Gas Emissions?

Agriculture is often cited as a primary source of greenhouse gas (GHG) emissions, but crop production and land use account for just over 13% of food-related GHG emissions globally. Altogether, food production in every stage accounts for 26% of global GHG emissions.

podcast
How Do You Measure soil carbon?

Agricultural soils hold great potential for sequestering carbon and improving soil health in the process. But how do you measure soil carbon?

article
How Much Carbon Can the Soil Sequester?

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.

article
What Are the Benefits of Increasing Agricultural Soil Carbon?

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.

article
How Does Carbon Cycle Through Agricultural Systems?

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.

article
How Does Crop Management Impact Carbon Sequestration?

Management practices either improve or set back soil carbon sequestration, beginning with the soil and moving through crop production.

podcast
How Does Carbon Get Into the Soil?

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?

article
Which Farm Practices Reduce Emissions & Sequester Carbon?

All aspects of crop production that involve keeping the soil covered, minimizing disturbance, and agronomic management can help sequester carbon and reduce emissions.

article
How Do Agricultural Emissions Compare to Other Sectors?

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.
