What K-humate(WHICH IS AN OMNIA (PTY) LTD ITEM AND IS COAL INDUSTRY BASED PRODUCT WITH EMISSION RELEASED DURING ITS DEVELOPMENT AND MANUFACTURE) does for you.
Humic acids promote beneficial soil microbial growth by providing active carbon for their energy and biomass requirements. Recent studies have shown that applications of water containing 150 ppm of K-humate® stimulated significant growth of both the active fungal and bacterial population in a solution of compost tea.
Stimulates growth of beneficial soil fungi and bacteria.
Provides readily available source of carbon for soil micro-organisms
Good chelating properties which reduce loss of nutrients due to leaching and run-off
Free-up many soil-bound nutrients, particularly phosphates, calcium and micro-nutrients
Lock-up aluminium in acidic soils which are harmful to plant growth
Good buffering capacity which help stabilise the soil against strong pH changes from fertilizer applications
Promotes soil agglomeration and better soil structure
Opens up heavy clays and hard, compact soils
Helps soil wetting which reduces surface soil crusting and improves water penetration and retention in the soil
K-humate® rejuvenates heavy clays which are compact and impenetrable to water and nutrients.
When soils dry out, water is removed from between the clay particles, causing them to move very close together, shrink in volume and form cracks in the ground. This cracking in the ground is a common feature in clayey soils which are poor or devoid of organic matter. Humic acids in nature interact with the clay particles and prevent them from sticking closely together when they dry out in the summer. The more open clay structure will be able to retain more water for plant use.
A compact, acidic brown-grey clay loam topsoil (A1 horizon 0 - 25cm, pH 4.6) with very low organic matter located at a vineyard was much more easier to wet after treatments with water containing less than 0.25% K-humate® (1 part K-humate® to 100 parts water). The soil treated with K-humate® was also found to retain up to 50% more water than the untreated soils.
Humic acids, like most forms of plant organic matter, improves the water holding ability of most soils. In sandy soils, humic acids form a hydrophilic (water-attracting) coating on the sand particles which increases their wetting ability and moisture retention properties. In clays, humic acids open up the clay structures to enable greater water penetration and retention.
Better soil wetting ability and greater soil penetration reduce water losses from run-off and drainage and improved water usage and reduction in labour requirement and costs.
Nutrient retention and availability to plants
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.
Sustaining balanced nutrition
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.
Sustaining balanced nutrition
Sustaining balanced nutrition
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-humates.
Sap analysis of watermelon plants growing on land where K-humate® has been applied, at a rate of 20 litres per hectare over a season, clearly showed much higher nutrient concentrations in the K-humate® treated plants than those grown without K-humate®. The improvements in nutrient uptake were also found with many other crops including tomatoes, potatoes and citrus. Higher nutrient concentration in plants and crops is very important not only to plants but also to human health.
Better root growth
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.

Attempts at promoting increased food production through improved soil fertility management in South Africa have been boosted with the development and marketing of industrially manufactured biological amendments (IMBAs). Manufacturers claimed the products have the potential of improving soil fertility and hence increase crop productivity when used either as boosters or total replacement to mineral fertilizers based on the manufacturers’ recommendation. Hence, this study was initiated during 2006/07-production season to quantify and compare the effect of selected products on maize yield and changes in soil microbial biomass carbon under different field conditions. Nine selected products and NPK fertilizer were used as recommended for maize at four trial sites (Potchefstroom, Bothaville, Ottosdal and Bethlehem). An unamended control plot was included in the treatments. The trial was laid out as a randomised complete block (RCB) design with four replicates. Soil sampling for microbial biomass C study was taken 1-month after treatment application at 4-weekly interval until harvest when grain yield was determined.
Results of the study gave an average grain yield 2.6, 2.4, 2.3 and 3.1 t ha-1 across treatments at Potchefstroom, Bethlehem, Bothaville and Ottosdal, respectively. Plots treated with the growth booster Molcast gave a higher yield increase than NPK plots at Potchefstroom and Ottosdal while few of the substances used as total replacement resulted in a marginal increase in grain yields. At Potchefstroom, plots treated with Molcast, Promis and K-humate resulted in a 12.7, 1.4 and 0.7 % grain yield increase, respectively. Similar results were observed at Bethlehem whereas at Bothaville it was the opposite. At Ottosdal, grain yields from all IMBAs treated plots were higher than NPK except for Growman. The highest yield increase of 40.3 % was obtained at Ottosdal in Molcast treated plots. Expectedly, all IMBAs treated plots had a higher content of soil microbial biomass C than NPK plots. Total replacement of inorganic fertilizer by IMBA induced biomass C mineralisation that was apparently more consistent in light-textured soils of Bothaville and Ottosdal. The highest microbial biomass C content of 0.72, 0.145, 0.385 and 0.180 mg C g-1 soil was measured at different sampling dates in K-humate, Montys, Crop care and Lanbac treated plots at Potchefstroom, Bethlehem, Bothaville, respectively. The correlation coefficients between soil microbial biomass C and maize grain yield obtained at all trial sites following application of IMBAs were generally low and not significant. Molcast and Montys seem quite promising products in terms of increasing crop yield and soil microbial biomass C content as well as consistency of efficiency across all trial sites.
