The purpose of this chapter was to study the influence of humic substances on the formation of the safety and quality of poultry meat. The high abilities of the natural and organic complex of humic acids “Reasil®HumicHealth” (produced in Russia, Saratov) to sorb and desorb five mycotoxins of compound feed (aflatoxin B1, ochratoxin, toxin T-2, zearalenone and fuminisin B1) were experimentally established. The hepatoprotective ability of humic acids was observed in experiments on broilers using rapeseed meal containing an increased amount of secondary plant metabolites that could cause liver damage. It was found out that the inclusion of humic acids in the amount of 1 and 1.5 g per 1 kg of feed to the main diet of broiler chickens has a more stable positive effect, both in terms of slaughter indicators (yield of semieviscerated carcasses and carcasses of complete evisceration), and in the production of the most valuable natural semi-finished products (breast, chicken legs) due to the intensive growth of muscle tissue. A clear improvement in the morpho-biochemical and immunological parameters of blood and micromorphometric characteristics of the organs of the immune system of poultry was noted with the use of different concentrations of humic acid salts. The use of the additive at the rate of 1 and 1.5 g per 1 kg of feed does not negatively affect the sensory indicators of finished culinary products.
The research has shown the positive influence of the liquid water-soluble combined-effect feed additive Reasil Humic Vet, which consists of a concentrated solution of high-molecular sodium salts of humic acids extracted from leonardite, on the growth vigor, preservation rate and the quality of carcasses of broilers, and confirmed the appropriateness of its use in broiler poultry farming.
There was studied the effect of humic fertilizers on the yield and quality of potatoes on irrigated dark chestnut soils of Saratov Zavolzhye in 2018-2020. The object of research was the Rosara variety released in the Volga region. For foliar treatments there were used the products manufactured by Life Force Group LLC. It has been established that, on average, three-fold foliar treatment of potatoes with Reasil Micro Hydro Mix over three years increased the yield of marketable tubers by 1.90 t/ha, Reasil Amino Copper by 4.02 t/ha. The maximum increase in yields was obtained on the options of the mix use of Reasil Micro Hydro Mix with Reasil Carb N Humic (6.49 t/ha) and Reasil Amino Cu with Reasil Carb N Humic (5.57 t/ha). With the application of fertilizers, the share of marketable tubers in the total yield increased significantly (compared to the control). In the tubers of plants enriched with fertilizers, an increase in the content of starch (by 3-5% compared to the control) and vitamin C (by 5-9% higher than the control) was noted.
There were considered the results of experiments with fertilizers, which were carried out with scientific fertilizers on the chernozem chestnut soils of the arid Volga region. The objects of research were grain fodder crops (spring barley, oats, grain sorghum, grain corn), as well as those used for green fodder (sugar sorghum, corn). It has been established that among mineral fertilizers, the leading role in yield increasing of forage crops belongs to nitrogen fertilizers but not phosphorus ones (as previously believed). The use of fertilizers based on humic acids had a positive effect on the growth, development and yield increase of forage crops. The maximum productivity in the experiments was achieved with the combined use of mineral nitrogen fertilizers and humic based products. The effect of all studied types of fertilizers depended on the weather conditions of the growing season.
