Agrocarb-FL

is a high-quality, natural agricultural lime product used to condition and enrich agricultural soils. Produced in a mining operation in central Vermont, Agrocarb-FL is created from processing natural marble ore into ground calcium carbonate; that is further processed into a fine textured liming agent with a median particle size of 20 microns. This unique fine texture allows Agrocarb-FL to quickly react in soil and to serve as a valuable substitute for commercial agricultural lime.

Algefiber

is derived from red seaweed. The carrageenan found in this sea vegetable is an ingredient used in food, health, and personal care products. Algefiber®, the byproduct of extracting carrageenan, contains organic matter and perlite and has a physical consistency similar to that of store-bought brown sugar. It is used to increase soil pH, as well as provide calcium, magnesium, and organic matter. Additionally, the plant hormones naturally present in seaweed have been shown to help increase plant root development and promote crop growth.

Fertilimer - Chateaugay, NY

is a lime-enhanced soil conditioner produced at our Grasslands facility in Chateaugay, New York. Fertilimer production starts with bioset advanced technology, which manages the exothermic reaction when quicklime is blended with dewatered biosolids. This reaction generates significant amounts of heat, which serves to effectively pasteurize Fertilimer and create a Class A product that enhances soil by offering high nutrient value and lime equivalence.

Fiberbed

is Casella Organics’ patented animal bedding blend of paper-mill byproducts, wood ash, and green sawdust. This special formula is an effective alternative to sawdust and shavings, which are becoming increasingly costly and hard to obtain.

Fibergro

is produced as virgin wood pulp is processed into tissue paper. The resulting byproduct from this process, Fibergro, consists primarily of short paper fibers and nitrogen. Use of this product—which has high organic content and is free of weed –seed—is a cost-effective way to improve soil condition and health. Fibergro has been used on agricultural soils since 1989, with proven ability to enhance soil structure, improve soil aggregation, and minimize soil compaction. Fibergro is also valuable when added to topsoil, improving organic matter levels and providing a source of slow-release nitrogen.

Lime Grit

is a coarse lime byproduct of the precipitated calcium carbonate (PCC) production process. PCC is used as a whitener in paper mills. The coarse nature of Lime Grit provides a gradual release of lime value over time. It is ideal for maintaining optimum pH levels in well-managed fields and sweetening the soil of fields.

Mill Lime

consists of calcium carbonate that is converted from quick lime in the kiln of a Maine paper mill. Mill Lime can be distributed with typical fertilizer spreading equipment.

Poultry Litter

This is approved for organic use and is an excellent source of nutrients that can be incorporated into most fertilizer programs. The key to successful management is to match the nutritional requirements of the crop with nutrients available in Poultry Litter and supplemental fertilizers.

Wood Ash

This emerges from the combustion of clean wood and bark to produce electricity. The resulting product is a soil amendment ideal for balancing soil pH and enhancing nutrient levels. Wood Ash contains significant amounts of magnesium, potassium, and many other micro-nutrients important to healthy crop growth. Since 1983, earthlife® Wood Ash has been chosen by farmers to increase soil pH, improve soil fertility, and increase crop yield. Wood Ash is easily applied with conventional lime- or manure-spreading equipment.
