However, we have finite resources, and the soil use needs to be more efficient to increase productivity and profitability. Considering it, here we try to understand the main soil parameters and the types of management that may interfere with soybean productivity, thus better visualizing the factors that may be limiting. Therefore, a questionnaire was prepared a and applied, between February and August 2020, to 29 producers of São Francisco de Assis who had their soil chemically analyzed during the harvests of 2017/2018, 2018/2019 and 2019/2020. After analyzing the data, the main conclusions observed are that, regardless of the year, which had quite different rainfall levels, the highest yields are achieved by producers who have better pH, base saturation and aluminum levels. These directly impact the soil's ability to provide nutrients. In years of low rainfall, these items are even more important, especially if combined with organic matter.

The experiment was conducted from February 18, 2020 to August 4, 2020, in a commercial field, where plots 30 meters long by 28 meters wide were demarcated, each plot 30 meters long with 8 rows of planting, with spacing of 0.5 m, totaling 120 m2. Fungicide applications were carried out at phenological stages V8; VT; R2; V8 + VT; VT + R2 and V8 + VT + R2. In the control treatment, no fungicide application was carried out. The product used was the fungicide containing Fluxapiroxade and Piraclostrobin, at a dose of 350 ml.ha-1 . After harvesting and weighing it can be verified that the plots with a fungicide application in the vegetative stages V8 and VT were the most productive and most profitable in relation to the control where no application was made. Plots where two and three fungicide applications were made did not obtain satisfactory production or profitability.

This is an exploratory, descriptive, opinion survey with non-probabilistic sampling, comprising 25 farmers from 5 cities in the Western Frontier of RS, comprising 113,118 ha hectares, of which 66,040 ha are adept of PA. The interviews allowed the correlation of qualitative and quantitative data, generating important information. In this sense, the profile of the properties under study has an average adhesion to PA of 75% of its area. The average size of these properties is 4,525 ha, 54% of which is owned and 46% leased. The predominant age group of PA supporters is 46 to 55 years old, representing 40% of the sample population. The predominant level of education of the adopters of the PA is Graduated, representing 52%. The main crops where PA tools are applied, in the Western Frontier of RS, are soybean (39%) and rice (26%). The average time of adoption of the PA in the Western Frontier is 5 years. The main intention of purchasing machines and equipment with PA is the Vacuum Planter representing 28% of the purchase intentions for the next 2 years.

Its grains are widely used by the agribusiness (production of vegetable oil and animal feed), chemical and food industry, as well as an alternative source of biofuel. Brazil is the largest producer in the world, but there is an productivity gap to be filled in. The content of phosphorus (P) available in the soil has been reported as a more generalized nutritional limitation to agricultural production. This study aimed was to evaluate the productivity of the soybean crop, submitted to different forms of application of phosphate fertilizer TOP-PHOS® (3% de N; 28% de P; 17% de Ca e 7% de S). Treatments constituted in the follow application forms: Witness (without P), P in the line and P to throw, in cultivar BMX ZEUS®. In the visual evaluation performed at 24 days after emergence, where the P was placed in the line close to the seeds (7 to 10 cm deep), there was a greater structuring of roots (volume and length) and aerial part, proving greater productivity between treatments. The treatment witnesses showing weakened plants, such as which had the lowest result in grain yield. Although the management with P at haul overcome in productivity in relation to the control, it did not achieve the same result as the management with P in the sowing line. Thus, because it is a little mobile element in the soil, and highly demanded by the soybean crop, the highest productivity is achieved when the phosphorus is close as roots.
