“…In Scotland, where agricultural soils are more acidic than in England, the co-benefit of ERW in raising soil pH could be considerable, with reductions to 10% by 2050 in S1 and eliminating acidic soils by 2045-2050 in S2 and S3 (Figure 3b). Reversing soil acidification across England and Scotland can increase nutrient uptake to boost yields on underperforming croplands 32,33 , lower the potential for metal toxicity 7 at low pH, and enhance nitrogen fixation by legumes 34 .…”

“…The negative effect of basic soils on soybean yield can often be attributed to a lower availability of iron (Kaspar et al., 2004; Moraghan & Mascagni Jr., 1991; Zocchi et al., 2007); however, iron deficiencies can also be attributed to biotic factors and agricultural practices, and not only to limited available iron (Hansen et al., 2004). Furthermore, acid soils (pH <6.0) with low Ca concentrations can also negatively affect legume nodulation and nitrogen fixation (Alva et al., 1987; Alves et al., 2021; Ferguson & Gresshoff, 2015; George et al., 2012). These negative effects driven by soil pH were not present in our study.…”

Soil balancing (SB), or base cation saturation ratio (BCSR), is a soil management approach that strives to maintain specific soil calcium (Ca) and magnesium (Mg) levels to improve soil health, decrease pest problems, have better crops, and increase crop yield. To achieve ideal levels of Ca to Mg, BCSR practitioners apply gypsum (calcium sulfate) and high‐calcium lime (Hi‐Cal lime) amendments, with the former increasing Ca base saturation and the later increasing both Ca base saturation and soil pH. We hypothesized that positive benefits ascribed by BCSR practitioners are due to increasing soil pH, rather than increasing Ca levels, both of which occur after lime application. Thus, we conducted successive applications of gypsum or epsom (magnesium sulfate) with and without Hi‐Cal or dolomitic lime, to either increase or lower soil Ca:Mg ratio and pH in an Ohio‐based experiment over 6 yr and evaluated soil and yield responses in a corn (Zea mays L.)–soybean (Glycine max L.)–small grain rotation. Repeated applications of gypsum with and without Hi‐Cal lime significantly increased soil Ca:Mg ratio and repeated applications of epsom with and without dolomitic lime significantly decreased the soil Ca:Mg ratio. Crop yield was not affected by soil Ca:Mg ratio for any crop in any year. However, over the 6 yr of the study, corn yields were positively related to increases in soil pH. We conclude that balancing soil Ca and Mg levels did not impact corn or soybean yields but managing soil acidity remains a fundamental tool to improve crop yields.

“…As stated earlier, the most soil chemical properties influencing soybean growth on tidal swamps were low soil pH and high Al saturation [14,15]. This can cause a decrease in nitrogen fixation and nutrient uptake, especially phosphorus which is important for cell growth and photosynthesis [9,16]. In addition to planting adaptive varieties and water management, soil amelioration is an important component for the success of soybean cultivation on tidal swamp lands.…”

“…This can cause a decrease in nitrogen fixation and nutrient uptake, especially P, which is important for cell growth and photosynthesis. The excessive accumulation of Fe has been linked to oxidative damage to proteins, lipids, and losses in chlorophyll content, so the photosynthetic process that is important for growth and crop yields is not optimal [8,9]. The tidal swamp lands type C, which is the most suitable tidal swamp lands for soybean development in Indonesia, it is a soil pH ranging from 3.60 to 5.30, and the Al saturation ranges from 2.8 to 51.5% (Table 2).…”

The demand for food, particularly as a source of protein for the majority of Indonesia’s population, has not yet been satisfied by the country’s soybean production. For these reasons, the government works nonstop to intensify and extend soybean production in order to enhance productivity. Indonesia has a sizable amount of tidal marsh area (more than 700 000 ha) that is spread out throughout a number of islands, including Sumatera, Kalimantan, and Papua. The physical and chemical characteristics of the soil, such as water saturation in the root zones, a low pH, and a high Al concentration for soybean growth, are the main limitations of this land. However, the area may produce high soybean productivity (2.0 - 2.5 t/ha) with excellent management techniques. It is already possible to grow soybeans on tidal marsh lands using land and plant management techniques like fertilization, water management, amelioration, and tolerance varieties. In order to ensure sustained national soybean production in Indonesia and achieve self-sufficiency, tidal swamp areas have tremendous potential and chances for development.
