Commercial humic products (HP) are currently being more and more actively used in agriculture. Often they are applied in tank mixtures with various agrochemicals: chemical fertilizers, plant protection products, bio-products. Developments of new scientifically based compositions (formulations) of HP with agrochemicals are promising both for manufacturers and scientists. Research and Production Enterprise NPO RET, producer of HP under the trade name Lignohumate®, is developing technologies for new generation of HP using Lignohumate (LH) as a basis for such formulations. Results of laboratory and field experiments are discussed in the presentation. Compositions with mineral fertilizers are developed and supplied for customers. Formulations based on LH and containing NPK and/or microelements (up to 50%) promote plant uptake of nutrients, plant growth and photosynthesis. Another direction is coating of chemicals’granules with LH. Addition of 0.1-0.5% of LH to NPK increased nutrients uptake from 50-55 up to 80-85%. Compositions with pesticides help to reduce residual toxicity and cost of chemical plant protection products. In many cases formulations of HP with fungicides enhanced their effectivity. Our experiments showed that application oа protective-stimulating compositions based on LH and a number of fungicides allowed to increase the effectiveness of fungicides, reduce their consumption rates and cost. Compositions with bio-products provide widening of effective concentrations and decrease of consumption rates of more expensive bio-products. Conclusion. Large-scale use of new generations of “humatized agrochemicals” can significantly reduce the environmental load on soil, to increase yield and improve the quality of agricultural production.
