Better Soils From a Better Biochar
ArborChar®, A Better Way to Grow
ArborChar® is uniquely built to be a soil amendment and fertilizer, blending nutrients to target specific plant needs with biochar to help improve leaf vigor, root and fruit growth, and soil structure, while aiding in the proliferation of soil microorganisms. ArborChar is designed to have neutral pH and produce minimal dust, and will not burn plant tissue. Made with biochar sourced from sustainably grown, untreated, unpainted, hardwood trees, and loaded with organic nutrients, minerals, blood meal, and bone meal, ArborChar All Purpose Grow 5-6-4 and Root, Flower & Fruit 3-6-4 go above and beyond traditional biochar products.
What is Biochar?
Biochar is an extremely porous charcoal, rich in carbon which enhances soils through retention of water and nutrients and increasing soil biodiversity. The use of biochar to enhance soil productivity goes back 2000 years, when Amazonians smoldered agricultural waste in pits or trenches. Today, biochar is made through a modern process called pyrolysis, the thermal decomposition of organic matter in the absence of oxygen, producing a porous and activated carbon material which helps to build soil, conserve water, and sequester carbon.
The burning and natural decomposition of organic matter and agricultural waste adds large amounts of CO2 to the atmosphere. Biochar can reduce the growth in atmospheric greenhouse gas levels by holding carbon in soils for thousands of years. The production of biochar is a carbon-negative process which removes more CO2 from the atmosphere than is released.
Water Retention & Soil Amendment
Biochar is recognized as offering several benefits to soil related to its porous nature and high surface area. The structure of biochar can attract and retain both water and water-soluble nutrients. Thus, nutrients are retained for the plant’s benefit instead of leaching into water. The porous structure is also an extremely suitable habitat for beneficial micro-organisms, which play an essential role in soil fertility and plant growth.
Soil pH & Cation Exchange Capacity
Nutrients are more plant available in acid soils. Optimum soil’s pH range from 5.5 to 7.0. Biochar generally has high pH (e.g. 6 – 10) so in areas where a soil pH is low, biochar can help to buffer the acidity in the soil, making nutrients like Iron and Phosphorus available for plants to take up through their roots and minimizing deficiencies.
Biochar can help create soils with high Cation Exchange Capacity (CEC). Surfaces that are negatively charged like biochar and organic matter hold on to positively charged nutrients because opposite charges attract. The soil can then “exchange” these nutrients with plant roots.
Use ArborChar on indoor and outdoor vegetables, herbs, annuals, perennials, trees, and shrubs. Add 1 to 4 tsp of ArborChar per container or use 3 cups to cover 200 sq. ft. Mix in 1 to 6 inches below the soil surface in new planting beds, around established plants, or in root zone when planting. Repeat applications throughout the growing season every two to four weeks to maintain optimal nutrition. Water in thoroughly after applications. For best results, plant with compost and water with NutriRoot.®
All Purpose Grow 5-6-4 offers a balanced package of NPK for general plant growth as well as 6% Calcium to help inhibit Blossom End Rot and 2% Magnesium to prevent yellowing. Root, Flower & Fruit 3-6-4 has a reduced nitrogen percentage to allow plants to focus on rooting and fruiting and contains 10% Calcium, and 2.5% Magnesium. ArborChar is available in 1 & 4 lb. bags and covers 200 to 800 sq. ft.
