“…Therefore, it is important to adjust the fertilizer doses based on soil analysis of removal after harvest. These adjustments are necessary to reduce the negative impacts of overuse of fertilizers -natural resources for the production of high-yield soybeans (Filippi et al, 2021).…”

“…Bender et al (2015) reported improvement over the preceding 80 years of the DM yield, uptake of nutrients, grain yield and HI. According to Filippi et al (2021), the new varieties are more demanding of nutrients, so there is greater removal per grain of the macronutrients K, P, Ca, Mg and S. Bender et al (2015) also reported that the macronutrients P, N, Cu and S had HI values of 81%, 73%, 62% and 61%, respectively, all greater than 60%, so these responses can cause limitations of yields due to inadequate avialability during reproductive growth. And according to Neto et al (2021), the new soybean varieties remove more N, P, K and Mg, with the quantities removed being in uenced by local conditions.…”

Aims Substantial variation exists in the patterns of uptake and remobilization of nutrients by modern varieties of soybeans. Furthermore, the fertilization programs in Brazil are often outdated. Thus, the objective of this work was to analyze these patterns in a soybean cultivar with indeterminate growth habit in two areas, one with moderate and the other with high productivity. Methods We analyzed the dry matter, macro and micronutrients in soybeans (Glycine max) divided into leaves, stems, pods and seeds, in six growth stages. The plants came from established farming areas with the same cultivation parameters and indeterminate growth habit. The data were used for descriptive analysis in function dry matter production, uptake of nutrients, harvest index, and nutrient uptake and remobilization rate. Results We found a greater uptake of nutrients in the older cultivars, mainly involving nitrogen, potassium and sulfur. And the nutrient removal, denoted by the harvest index, varied according to the location, with a trend of export of greater quantities of nitrogen and phosphorus. These increases were positively related with the dry matter content but not with the nutrient export. The rate of uptake and remobilization of nutrients changed with demand for nutrients throughout the crop cycle. Conclusions For sustainable production of soybeans in Brazil, we suggest revision of the fertilization manuals to increase the average yield. Agronomic practices also need to assure adequate availability of nutrients during the reproductive growth stage.

“…Potassium (K) is an essential nutrient for plants and highly demanded by agricultural species (Firmano et al, 2020). Together with nitrogen (N), it is the nutrient absorbed in greater quantities by plants (Filippi et al, 2021), and when in excess in the soil, plants can use it beyond their need for luxury consumption (Kang et al, 2014;Fornari et al, 2020). Data collected in the meta-analysis by Filippi et al (2021) show the largest export of K by the most recent soybean cultivars, noting that in most of Brazil, K replacements are below what is necessary.…”

So, with the increased export of nutrients, including K, critical levels could be above the actual requirement of plants, reinforcing the need for constant research to update fertilizer recommendations.…”

Soils with low potassium (K) availability require corrective fertilization for grain crops. The recommended rate to increase K availability up to the critical level depends on the soil K buffering capacity (KBC). This study aimed to quantify the KBC and recalculate the rates necessary to reach the K critical level in 23 soils from Southern Brazil. Soil samples were incubated with six K rates, that were thus grouped according to CEC pH7.0 : below 7.5 cmol c dm -3 (0, 30, 60, 90, 120 and 180 kg K 2 O ha -1 ); from 7.6 to 15 cmol c dm -3 (0, 30, 60, 120, 180 and 240 kg K 2 O ha -1 ) and from 15.1 to 30 cmol c dm -3 (0, 30, 60, 120, 240 and 360 kg K 2 O ha -1 ). The soil test K (STK) was extracted by Mehlich-1 and the fertilizer rates necessary to increase the STK by 1 mg dm -3 were quantified. The KBC values were correlated with a suite of soil testing metrics. The relationship between the cation exchange capacity (CEC pH7.0 ) and KBC was modeled, and a linear-plateau equation presented the best fit. The K rates were calculated using the following equation: K rate = (Critical Level -STK) × KBC and were compared with the current rate indicated by the Local Soil Fertility Committee. The K fertilizer rates by KBC were about 2.5 times higher than the values currently indicated, and the largest differences were observed in soils with low STK and high CEC pH7.0 .
