What does biochar do for soil? Improves Soil Structure: Biochar helps enhance the physical structure of soil by increasing its porosity. This improves aeration and reduces soil compaction, creating a more favorable environment for plant roots and beneficial soil organisms. Increases Water Retention: Due to its porous nature, biochar can hold water and make it available to plants over time. This is particularly beneficial in sandy soils or areas prone to drought, as it helps retain moisture and reduce the need for frequent watering. Enhances Nutrient Retention: Biochar has a high cation exchange capacity (CEC), meaning it can adsorb and retain essential nutrients like nitrogen, phosphorus, and potassium. This prevents nutrients from leaching away and makes them more available to plants. Boosts Soil pH and Reduces Acidity: Biochar can help buffer soil pH, making acidic soils more neutral. This is beneficial for crops that prefer neutral to slightly alkaline conditions and helps improve nutrient availability. Promotes Microbial Activity: The porous structure of biochar provides a habitat for beneficial microorganisms, including bacteria and fungi. These microbes play a key role in nutrient cycling, organic matter decomposition, and overall soil health. Reduces Greenhouse Gas Emissions: Biochar can reduce the emission of nitrous oxide (a potent greenhouse gas) from soil, particularly in agricultural systems that use nitrogen fertilizers. It helps create conditions that favor the conversion of nitrogen into forms less prone to release as gas. Increases Organic Matter: When added to soil, biochar contributes to the overall organic matter content. This improves soil fertility, enhances carbon sequestration, and supports a healthy soil ecosystem. Mitigates Soil Contaminants: Biochar can adsorb certain soil contaminants, such as heavy metals and organic pollutants, reducing their bioavailability and toxicity. This is useful in remediating polluted soils. Supports Plant Growth: By improving soil conditions, biochar indirectly supports healthier and more robust plant growth. Plants grown in biochar-amended soils often exhibit better root development, increased biomass, and improved crop yields. Long-Term Soil Health: Unlike other organic amendments that decompose over time, biochar is highly stable and remains in the soil for hundreds to thousands of years, providing long-term benefits and maintaining soil health over extended periods. Overall, biochar acts as a powerful soil conditioner, enhancing soil properties, supporting plant growth, and contributing to sustainable agricultural practices. learn more www.showmethecarbon.com buy now www.showmethecarbon.com

Biochar what to do? Here are some ways to use biochar in your garden: Top dressing Sprinkle activated biochar on top of the soil and wet it. You can also mix biochar with compost before applying it as a top dressing. In the root zone When planting, mix one part biochar with nine parts compost and add it to the soil in the root zone. You can also mix biochar with soil at different ratios depending on the application type. For example, you can mix one part biochar with one part compost and two parts soil when preparing landscape beds, or one part biochar with 19 parts soil when applying to lawns. Hand mixing If you're planting in pots, you can mix biochar into the soil with your hands or a rake.
