“…Известно [34][35][36], что и гуминовые биосредства, и микробные препараты участвуют в формировании почвенной структуры, активизируют почвенную микрофлору, влияют на миграцию питательных элементов и т.д. Так, корневая и некорневая подкормки гуминовыми препаратами Лигногумат и BIO-Дон посевов зерновых культур оказывали влияние на структурное состояние и биологическую активность чернозема обыкновенного: коэффициент структурности повышался от 0,7 до 2,6, численность различных групп микроорганизмов достоверно увеличивалась на 150 % [37]. Авторы [38] отмечали, что обработка посевов сахарной свеклы различными биопрепаратами влияла на биологическую активность почвы за счет увеличения активности ферментов классов оксидоредуктаз и гидролаз в 1,2-1,7 раза по сравнению с контролем и за счет повышения общей численности микроорганизмов в ризосфере: после 1-й обработки биопрепаратами -в 1,4-8,0 раза, после 2-й -в 1,9-3,6 раза.…”

One of priority directions in cultivation of carrots is development of new techniques in technologies allowing to increase not only the yield, but also the quality of root crops. Treatment of vegetative plants with various biological products, growth regulators and hemin preparations is the most promising technological method for increasing carrots yield and quality. The purpose of the research is to study the effect of liquid-phase biological means of various natures on yield and quality of Karini variety carrots grown on peat soil. The experiment had been carried out in 2015-2016 on peat soil of the Dmitrovsky department of VNIIMZ branch FRC V.V. Dokuchaev Soil Science Institute (Moscow region). Two microbiological preparations (LPB and Azotovit) and two humic (BoHum and FlorHumat) were tested. Azotovit and FlorHumat are known registered preparations, and LPB and BoHum are the latest developments of VNIIMZ. The biological means were applied three times during growing season against the background of the main fertilizer P40K60. The largest increase in carrot yield was obtained when using LPB and BoHum - 19.4 and 18.3 %. Humic preparations contributed to a higher level of mineralization processes in soil, providing plants with available nutrients. Improvement in quality indicators of carrots for all tested biological means was noted: a higher content of carotene in root crops in the variant with BoHum - 101 mg/kg, dry matter - when using Azotovit - 9.35 %, the minimum content of nitrates when using FlorHumat preparation - 101 mg/kg. In general, the impact mechanism of the biological means used was their complex effect on plants and soil, which is of certain value for fundamental research. The method of cluster analysis showed a high degree of similarity in efficiency of bio-means LPB and BoHum in terms of set of indicators (yield, quality of carrots, agro-chemical and microbiological indicators of soil). The most promising is the humic biological mean BoHum. The considered biological means used for cultivation of carrots on peat soils will improve provision of processing industry with a raw material base, and population with high-quality vegetable products.

Nutrient management of high-density apple orchards remains to be a serious problem in central Russia. Enhancing apple productivity by applying higher fertilizer rates leads to an increased environmental burden and undesired consequences. Although the transition to organic farming may solve many horticultural problems, conventional methods still produce higher crop yields. One of the most pressing issues consists in reducing mineral fertilizer use by applying more organic substances. This approach allows soil fertility to be preserved while maintaining high levels of plantation productivity. In the present research, particular attention was paid to potassium nutrition of apple trees. During 2020 and 2021, we studied the effect of potassium fertilizers in various standard amounts and silicon-modified potassium humate on the state of apple trees cv. Ligol grafted on 62-396 rootstock in the experimental orchard of I.V. Michurin Federal Research Center. The orchard was planted in 2018 according to a 1.2×4.5 m pattern (1852 trees per hectare). The experimental design was as follows: control (irrigation); full standard amount of N20P6K28 fertilizers; ¾ standard amount of N15P4K21 mineral fertilizers + ½ standard amount of potassium humate, ½ standard amount of N10P3K14 mineral fertilizers + ½ standard amount of potassium humate; full standard potassium humate amount of 10 L/ha. In 2020, the introduction of potassium humate provided the maximum yield, although without significant differences compared to the use of mineral fertilizers. In 2021, the yield was also at the level achieved with mineral fertilizers. Potassium humate provided a higher nitrogen content in the leaves as compared to mineral fertilizers, largely due to a significant increase in the availability of nitrogen and potassium in the soil. The content of available phosphorus was not significantly affected. This assumes that the effectiveness of humates depends on the soil type. The combined application of reduced standard amounts of mineral fertilizers and potassium humate contributed to maintenance of high yields under with a less dramatic increase in soil acidity.
