Regenerative Agriculture & Soil Carbon
What is Carbon Farming?
Carbon farming encompasses agricultural practices that increase carbon sequestration in soils and biomass, including conservation tillage, cover cropping, and improved grazing management, while maintaining or improving farm productivity.
Sentinel Earth structures carbon farming projects that connect farmers with carbon finance, navigating methodologies like VM0042 to quantify soil carbon gains and generate verified removal credits.
What is Soil Carbon?
Soil carbon refers to carbon stored in soils as organic matter, ranging from actively cycling compounds to stable forms that persist for centuries, with storage capacity increased through regenerative agricultural practices.
Sentinel Earth develops soil carbon projects across agricultural landscapes, applying methodologies like VM0042 to quantify carbon sequestration from conservation tillage, cover cropping, and improved management while verifying gains through soil sampling.
What is Soil Health?
Soil health is the capacity of soil to function as a living ecosystem that sustains plants, animals, and humans, characterized by biological activity, nutrient cycling, water infiltration, carbon storage, and resilience to disturbance.
Sentinel Earth's regenerative agriculture projects prioritize soil health as both a climate solution and agronomic benefit, helping farmers adopt practices that build soil carbon while improving yields, reducing input costs, and enhancing resilience.
What is Conservation Tillage?
Conservation tillage is a farming practice that minimizes soil disturbance during planting and cultivation, preserving soil structure, reducing erosion, sequestering carbon in soil, and protecting beneficial microbial communities.
Sentinel Earth's regenerative agriculture projects incorporate conservation tillage as a core practice, quantifying its carbon benefits through biogeochemical modeling and field verification under VM0042 methodology.
What is Cover Crops?
Cover crops are plants grown between main crop seasons primarily to protect and improve soil rather than for harvest, preventing erosion, fixing atmospheric nitrogen, suppressing weeds, and building soil organic carbon.
Sentinel Earth's agricultural carbon projects integrate cover cropping as a key practice for soil carbon sequestration, working with farmers to select species and manage timing for maximum carbon and agronomic benefit.
What is Crop Rotation?
Crop rotation is the systematic alternation of different crops across growing seasons on the same land, breaking pest and disease cycles, improving soil structure, enhancing nutrient cycling, and increasing soil carbon storage.
Sentinel Earth works with farmers to design crop rotations that optimize both agricultural productivity and soil carbon sequestration, documenting rotation changes for carbon credit quantification and verification.
What is No-Till Farming?
No-till farming is an agricultural practice that eliminates plowing and soil inversion, planting seeds directly into undisturbed soil to preserve soil structure, prevent carbon loss, reduce erosion, and conserve moisture.
Sentinel Earth's regenerative agriculture projects incorporate no-till practices where agronomically appropriate, modeling their carbon sequestration benefits and verifying implementation through field monitoring and farmer documentation.
What is Nutrient Management?
Nutrient management involves strategic application of fertilizers and soil amendments to optimize crop nutrition while minimizing greenhouse gas emissions, particularly nitrous oxide, through precise timing, placement, and formulation choices.
Sentinel Earth's agricultural projects implement improved nutrient management as both an emission reduction and soil health strategy, quantifying N₂O reductions through biogeochemical modeling verified by field data.
What is Crop Residue?
Crop residue is the plant material remaining after harvest, including stalks, leaves, and roots, that when retained on fields rather than removed or burned, decomposes to build soil organic matter and sequester carbon.
Sentinel Earth's regenerative agriculture projects incorporate crop residue retention as a soil carbon practice, quantifying its contribution to carbon sequestration through field sampling and modeling under verified methodologies.
What is Organic Matter?
Organic matter is carbon-based material in soil derived from decomposed plant and animal residues, living organisms, and microbial biomass, essential for soil fertility, water retention, nutrient cycling, and carbon storage.
Sentinel Earth's soil carbon projects build organic matter through conservation practices, tracking changes through laboratory analysis and modeling to quantify carbon sequestration for verified credit generation.
What is Chernozem?
Chernozem, meaning "black earth" in Russian, is a highly fertile soil type formed over millennia in temperate grassland regions, characterized by exceptional organic matter content and carbon storage capacity reaching depths of several meters.
Sentinel Earth's Ukraine regenerative agriculture projects leverage Chernozem's natural carbon storage potential, helping farmers rebuild soil health while generating verified carbon removal credits through VM0042 methodology.
What is VM0042?
VM0042 is Verra's methodology for quantifying greenhouse gas emission reductions from improved agricultural land management, using biogeochemical modeling (DNDC) to measure soil carbon sequestration and nitrous oxide reductions from conservation practices.
Sentinel Earth applies VM0042 methodology in agricultural carbon projects, managing the complex DNDC modeling process, field data collection, and verification requirements to generate verified soil carbon removal credits.
What is Crediting Period?
A crediting period is the timeframe during which a carbon project is eligible to generate and issue carbon credits, typically ranging from 7 to 30 years depending on project type and registry requirements.
Sentinel Earth structures projects with crediting periods that balance carbon finance economics with long-term environmental integrity, managing renewals and recalibrations as methodologies and markets evolve.
