Effect of humic products and chelated microfertilizers on carrot productivity during irrigation

Abstract

Life Force LLC, RPE products were studied on irrigated dark chestnut soils of the Saratov Transvolga region. The objects of the studies were Chantenay carrot variety and products, containing humic acids, as well as macro (nitrogen), meso (calcium, magnesium and trace elements). The purpose of the research is to determine the most effective combinations of humic acid salts and chelated micronutrient fertilizers that provide a substantial increase in the yield of carrots. It is established that spraying carrots with a solution of Reasil® micro Hydro Mix increased the harvest of standard root crops by 1.85 т/ha for an average of three years (by 7% to the control). When using K- Humate -Na with micronutrients the yield increased by 5.51 t/ha (by 20% to the control). The maximum productivity of carrot within our experiments was obtained with the double application of Reasil® Carb-N-Humic along with K-Humate -Na with micronutrients (35.88 t / ha). Similar results (35.69 t / ha) were obtained when Reasil Ca-Mg-B Animo was used along with K- Humate -Na with micronutrients. The growth of carrots and the formation of the crop were significantly influenced by the weather conditions of vegetation season. The studied products had a positive effect on the output of standard root crops, the content of sugars, vitamin A and nutrients. The content of nitrate nitrogen in all variants of the experiments was almost the same and about 4 times lower than the maximal permissible concentration (MPC). The removal of macronutrients from the soil with the carrot yield increased under the influence of microelement fertilizers.
