TECHNOLOGY FOCUS - ENVIRONMENT - Preferred Soil Enhancing Material: The soil enhancing material provides enhanced growth and/or development of the plant when grown in a growing medium containing the soil enhancing medium by forming the soil enhancing medium, adding the soil enhancing material to a plant growing medium, planting the plant in the plant growing medium, and allowing the plant to grow and/or develop in the plant growing medium. The soil enhancement material comprises 40-95% by volume of bark in the form of pieces or particles, 5-40% by volume of a viticulture product or a product derived from a viticulture material, and 5-40% by volume of an organic humate. The soil enhancement material comprises a bark component or a component derived from a bark material, a coir component or a component derived from coir, a viticulture component or a component derived from a viticulture material, and organic humate, where the viticulture product is obtained as a waste product from viticulture and the organic humate is derived from a naturally occurring material. The soil enhancement material is a compost or a component of a potting mix or potting mix formulation or potting combination, where the compost component is up to 95% by volume of the potting mix or potting mix formulation or composition. The material derived from vegetation includes bark, including both composted bark and/or aged bark, grape marc, including pre-treated grape marc, a material derived from coconut including coir such as coir pith, coir peat, coir chips, coir mash, or humate materials. Preferably, the viticulture product is grape marc, grape must, pomace, grape pomace, or winery pomace, optionally containing seeds or being seedless. It has a moisture content of 10-70% moisture, preferably 55% by weight of moisture. The viticulture product is pre-treated before use, such as treated, sized, washed, conditioned, improved, refined, or filtered. Specifically, the viticulture product is grape marc having a seed content of greater than 10% by weight, preferably greater than 50% by weight. The grape marc compost or grape marc contains free potassium at 2-3% by weight. The grape marc further includes low levels of calcium, sulfur, and magnesium in amounts of less than 1% by weight, phosphorus in an amount of 0.1-0.3% by weight, and nitrogen at 1-2% by weight. One of the material derived from vegetation is bark including raw bark, fresh bark, aged bark, composted bark, or treated bark, including small amounts of composted or partially combusted bark. The bark is a pine bark obtained from pinus radiate trees or is obtained from Hoop Pine (Araucaria cuninghamii) or Slash Pine (Pinus elliotti). It is sized prior to incorporation into the composting mixture, where the size of the bark is 5-10 mm or more. The particle size of the bark and the particle size of the grape marc are compatible or comparable to form a mixture of the bark and grape marc having uniform distribution. The coir is in the form of chips, ranging in size of up to 50 mm, preferably 20-25 mm. The composting mixture further includes a humate or a mixture of two or more different humate materials. The amount of humate is 50% by weight, preferably 5-30% by weight. Specifically, the humate is or is derived from brown coal (lignite). The amount of humate material is up to 50% by volume, preferably 10-30% by volume based on the total volume of the plant growing material. The humate is also subjected to a pre-treatment step before being incorporated into the composting mixture or potting mix, where the pre-treatment step includes a washing step. Treatment of the humate includes sizing of the humate into batches having different size ranges in which the size ranges are the same as or comparable to or compatible with the size ranges of the bark component, and the grape marc component or other materials are added to the composting mixture to facilitate composting of the mixture by promoting a beneficial effect between the components of the mixture. The humate is present in batches of different sizes in which a first batch has a size of 6-10 mm. The potting mix formed from the composting mixture has a granular size or texture. The humate material or composting material includes a moisture control material for maintaining the moisture content of the mixture, where the moisture content of the humate and/or of the composting mixture is maintained at 30-70%, preferably at 40-65%. Composting of the mixture occurs in a windrow, where the temperature within the windrow is maintained at 40-70 degrees C, preferably 65 degrees C. The windrow is provided with different zones, regions, layers, or segments located within a single windrow. There is an outer zone and an inner zone so that the windrow is structured so that the outer zone at the perimeter forms an insulating layer useful for retaining heat build up within the inner layer of the windrow. Composting of the grape marc and bark takes place at 30-70 days, preferably 36-63 days. The oxygen content of the composting material is not lower than 5-10%. There is also a synergy or beneficial relationship between the composting bark and composting grape marc, which facilitates additional composting of both the bark and the grape marc to form compost. The bark is provided with a first set of microorganisms and the grape marc is provided with a second set of microorganisms in which the first and second sets of microorganisms interact with each other, preferably synergistically interact together to produce beneficial compost. The soil enhancement material further comprises one or more additives selected from wetting agents, grits, sand, pH adjustment agents, microorganisms, yeast, or organic fertilizers. The pH of the composting mixture is adjusted to 5-8, typically 5-6. The microorganism is selected from bacteria, actinomycetes, fungi, algae, protazoa, or rotifers.
