Liquid Humus 1 Lt, Technaflora. Liquid Humus is an unsurpassed natural and organic source of concentrated essential nutrients, vitamins and trace elements. Technical humic acids aid plants to best utilize the vitamin and nutrient benefits of a complete feeding program. These complex molecules are formed as organic matter decays, and occur naturally in soils, peat, oceans and fresh waters. Technaflora concentrated Liquid Humus is a 100 percent organic solution of 15 percent technical humic acids extracted as salts from a soft coal called Leonardite. Humic acids are able to chelate metals, notably iron, facilitating easier absorption by plants. Liquid Humus increases the permeability of plant membranes and the buffering capabilities of the medium, promoting the uptake of nutrients. Excellent for use in both hydroponic and soil environments, humic acids can be especially beneficial in dry areas by aiding in water retention. With the systematic application of Liquid Humus, the results are healthier, lusher plants with faster growth, more vigor and larger yields.
