“…Trop., Goiânia, v. 53, e74945, 2023 Despite not showing a significant difference under different potassium doses, the grain yield presented an average yield of 3,345 kg ha -1 , a result considered satisfactory, since the national average for soybean yield is 3,029 kg ha -1 , and the average yield for the Goiás state is 3,714 kg ha -1 (Conab 2022). In similar studies, Souza et al (2017) concluded that using Penergetic brings positive results and benefits in soybean production, increasing the grain yield by adding only NPK + micronutrients. Lima et al (2022) suggest the incorporation of additional organic matter to evaluate the effects of Penergetic throughout cultivations, and Franco et al (2018) point out that effective bioactivators require an adequate level of organic matter.…”

Soil microorganisms are of paramount importance for crop yield. This study aimed to evaluate the effect of potassium chloride doses associated with two bioactivation sources on soybean yield and soil microbial activity. The experimental design was randomized blocks, arranged in a 5 x 2 factorial scheme, with four replications, being the first factor potassium doses (0, 30, 60, 90 and 120 kg ha-1 of K2O), using potassium chloride as a source, and the second factor soil bioactivation products: Penergetic (250 g ha-1) and Efficient Microorganisms (EM) (1:250), with 250 L ha-1 of spray volume. The KCl doses affected the soil microbial activity, while the soil bioactivating sources with the potassium chloride doses did not show significance for the leaf potassium content and soybean yield. K2O doses higher than the maintenance dose for the soybean crop with EM negatively influenced the soil microbial biomass. The EM bioactivator associated with the maintenance dose of K for the soybean crop (60 kg ha-1) is the most appropriate treatment for soil microbial activity, as it is the condition that presents the most stable environment and the highest microbial efficiency.

“…According to Aparecido de Souza et al (2017), bentonite-based soil bioactivator powder intensifies and accelerates biological activities in cropping systems and plant photosynthesis. Their use does not replace the fertilization of macro-and micronutrients but can complement the nutrition required by crops, improving the absorption of immobilized nutrients.…”

Soil organic matter is considered a potential source of phosphorus (P) for plants because of biological cycling. Bioactivators are characterized as tools that can help soil microbial activity and the availability of P demanded by plants. The objective of this study was to evaluate the influence of the use of bioactivators and phosphate fertilization on the activity of soil microbial biomass and humified fractions of organic matter. The experimental design was completely randomized in a factorial scheme (6 × 2), with the first factor consisting of six doses of phosphorus applied to the soil (0, 30, 60, 90, 120, and 150 kg ha-1 of P2O5), using triple superphosphate as the source, and the second factor being the presence or absence of soil and plant bioactivator application, with four replications. The evaluated characteristics were soil microbial biomass carbon (SMBC), soil basal respiration (SBR), microbial biomass nitrogen (MBN), metabolic quotient (qCO2), microbial quotient (qmic), total organic carbon (TOC), fulvic acid fraction carbon (FAC), humic acid fraction carbon (HAC), and humin fraction carbon (HUMC). The use of soil and plant bioactivators and mineral phosphate fertilizer promoted changes in soil microbial activity. Increasing doses of phosphate fertilization promoted a reduction in the carbon characteristics of microbial biomass and basal soil respiration in the presence or absence of soil and plant bioactivators. Moreover, the use of bioactivator promoted higher averages for soil microbial biomass carbon, soil basal respiration, metabolic quotient, humic acid and humin and reduced the levels of microbial quotient, total organic carbon and fulvic acid.

“…One such method is use growth activators, whose beneficial effect was noted not only in the cultivation of wheat [4,5], but also in maize [6], coffee [7], soybean [8], legumes [4,[9][10][11], potato [12] and sugar beet [13,14].…”

The introduction of the “Farm to Fork” strategy in the EU will require a significant reduction in mineral nitrogen fertilization, and therefore the introduction of innovative production technologies to prevent a decline in agricultural production. Studies carried out in several locations in Poland in 2016/17–2018/2019 tested the possibility of replacing 30% of the dose of mineral nitrogen with growth activators alone, in combination with plant growth promoting rhizobacteria in the cultivation of winter wheat. It was confirmed that these two combinations allowed the obtention of a higher yield of grain by 13%, compared to the full nitrogen dose. Simultaneously, the grain quality did not change significantly. In some locations, a decrease in the content of nitrates in the soil was observed, which may mean a greater uptake of this nutrient by plants and an increase in the content of some available macro- and micro-elements, mainly phosphorus, magnesium, zinc, copper and iron, and soil organic carbon. Introducing the studied treatment and limiting the fertilization with mineral nitrogen of wheat in Poland by only 30 kg ha−1 N would save its consumption by 72 thousand t per year.
