When your soil becomes depleted, your crops suffer. They become weaker and it’s an open invitation for pests to come in and devour all the hard work you’ve put into them. Adding Humates is the most efficient way to increase the humus content of soil, as it is highly concentrated and much easier to apply than any other form of humic matter. Humates are highly concentrated, natural organic humus, formed through the biological breakdown of plant life over millions of years.  Also, since humates are completely decomposed, they enter into no nutritional competition with plants for nutrients such as nitrogen (not the case with incompletely decomposed compost).

Pulverized leonardite powder is a biochemically active concentrated source of humic acids containing 70% humic acid (by weight). Naturally-occurring, unaltered oxidized lignite is pulverized to a particle size 90% less than 30 mesh. This powder is an organic material which is added to your soil to enhance uptake of nutrients, increase microbial activity and stimulate soil life, and can be used as a supplemental source of trace elements.

Benefits of Humates:

Increased Crop Yields -- Humates can improve root development, total leaf area and total crop yields per acre.
Increased Root Growth -- Tests have shown that root system vigor is very important to the nutrient uptake capability of plants, as well as to the plant's ability to combat disease.  In addition, plant stability is enhanced, and plants are better able to find and absorb water with a broad based root system.
Increased Chlorophyll Content -- Humic matter has been shown to increase the chlorophyll content in plants, and can prevent or correct chlorosis.
Increased Nutrient Uptake -- Humates have been shown to consistently improve the uptake of nutrients such as nitrogen, phosphorus, and iron, as well as innumerable trace elements essential for plant health.  
Improved Plant Quality -- Humates can improve the quality of fruit, vegetables, and flowers by improving their physical appearance, and in the case of food crops, their nutritional value.  Cereal crops have shown more balanced amino acid content, and higher protein content.  All of this can enhance their worth in the marketplace.
Enhanced Natural Defenses -- Many toxins are inhibited or neutralized directly by bonding interactions with humic acids.  Plants which are healthy and receive all of their required nutrients are better able to combat disease and pests.
Improved Soil Structure -- Humus combines with clay minerals to form structural units called aggregates which help to stabilize the soil and increase its permeability to water and gaseous exchanges. The use of humates can prevent soil cracking, which exposes roots to the air and can cause crops to burn in severe heat conditions and improves overall soil structure to help defend against erosion.
Improved Water Retention -- Humates can hold up to 20 times their weight in water.  By enhancing the soil's ability to retain water, humate usage can reduce the need for crop irrigation.  This can be especially helpful with sandy soils, and contributes a large measure of drought resistance to crops.
Differing Soil pH --Humates create an environment where plants are able to grow healthy in a wider pH range.


Leonardite Application Guidelines

  • Lawns: When making a liquid solution, apply 2.5 lbs for 100 sq. feet of seedbed and 1 lb for every 100 sq. feet of established lawn.
  • Compost: Apply at a rate of approx. 1% of total mix by weight. Mix thoroughly. 
  • Banding: Apply either with seed or after planting and reduce application rates proportionally.
  • Field Crops: When creating a liquid solution, apply 75-150 lbs per acre. Broadcast in fall post-harvest or early spring before planting with seed.
  • Garden Vegetables & Flowers: Create a liquid solution or till into garden at a rate of 1-10 lbs per 100 sq. feet.
  • Container Pots: Mix in 1/2 - 1 tablespoon per gallon of soil.
  • Grapes Roses & Shrubs: Apply 1/4 lb around each plant, lightly till into soil, and water in.

Can be applied to all crops and compost.
