Ten years ago we were un happy with the quality and performance of the imported humic acid granule (Chinese manufactured) that we were using on our client farms across New Zealand. We decided to test all humic acid products on the market to find the highest quality and concentration of humic acid. After testing all products available in New Zealand and off shore we decided on Omnia’s humic acid products manufactured in Australia. Omnia’s humic acid products tested up to three times the humic acid content compared to all others.
We are the New Zealand importer for Omnia’s humic acid product range and have been using them extensively across New Zealand on thousands of hectares and are very happy with the results and farmer feedback around quality of product and ease of use.
The brown coal fields of the Gippsland basin in South Eastern Victoria are the only known source of high quality humates in Australia, producing what is possibly the richest of all humates mined in the world today!
These brown coals or lignite’s were formed when Australia was part of a great land mass called “Gondwanaland” some 20-50 million years ago when dinosaurs roamed the earth.
In geological time this period was between the Late Eocene and Middle Miocene ages when, in waterlogged environments, plant and tree debris accumulated. As the layer of debris increased in thickness, the floors of these vast swamps subsided slowly and the plant material was decomposed by the action of micro-organisms.
To varying degrees, and depending upon the climatic conditions plant constituents, including proteins, starches and cellulose were decomposed under aerobic conditions (in the presence of oxygen) by a process called “Humification”.
This process results in the formation of thick layers of rich peat and humic materials. This is why some people call the brown coals of Victoria the “50 million year old compost.” As this material is covered with sediment, the combined effects of time, temperature and pressure convert the peat firstly to brown coal and then to black coals.
In the transition from brown coal to black coals humate content decreases, oxygen content decreases and carbon content increases. Generally speaking, the older the coal the lower the humate content. Black coals have no humate, but the brown coals in Victoria are rich in humate being relatively young. These humate rich coals are only found in the South Eastern part of Australia in the Gippsland Basin.
Within the Gippsland Basin of Victoria where these brown coals are found, there also occurs a unique geological material which has undergone natural, in situ, weathering and oxidation. This material is known as Australian Leonardite.
Soil organic matter (humus) has a great ability to hold nutrients in the soil until they are required by plants. It is the humic acid molecules in the humus which hold most of the nutrients from applied fertilizers.
K-humate, with its high concentration of humic acids, greatly improves the ability of sandy soils to hold many essential nutrients such as ammonium, potassium, calcium, magnesium and the trace elements.
Humic acids, which are trapped in cracks and pores and adhered to the surfaces of sand particles, hold onto many important nutrients which would have been otherwise lost to leaching.
Like the saying goes, “You are what you eat”. Similarly, the well being of plants depends not only on what you feed your plants, but also on the availability of the nutrients in your applied fertilizers and how successfully the plants are able to take these nutrients through their root system and foliar.
K-humate soil conditioner increases the movement of calcium down the subsoil and plant root zone where it is most needed. Greater calcium concentration in the soil treated with K-humate was evident down to a depth of 16cm. This means quicker response from applied calcium in terms of nutrient availability and plant uptake.
Calcium is important in promoting plant cell development which will result in healthier plants, greater resistance to diseases and better crop quality. Scientific studies have shown that a large proportion of your fertilizers are locked-up in the soil soon after application, particularly phosphates, calcium and micro-nutrients.
K-humate can unlock some of the bound phosphate and micro- nutrients in the soil by chemical reactions which solubilise the fixed phosphates. Additional phosphates are also released by microbial activity brought about by the presence of K-humate.
K-humate also stimulates greater root growth in seedlings and mature plants resulting in higher nutrient uptake in plants and a greater ability to tolerate extended dry spells between irrigations or rainfall. A more extensive root system growth promotes greater plant vigor and better crop yield and quality.
