“…Liming increased the foliar content of Ca and Mg (Table 2), corroborating reports on the limestone as an efficient source of Ca and Mg supply for crops (Deus, Büll, Guppy, Santos, & Moreira, 2020; Schenfert et al., 2020). By increasing the soil pH, neutralizing toxic Al 3+ and releasing Ca 2+ and Mg 2+ , liming provides optimal conditions for root system growth, consequently increasing nutrient uptake by plants (Moreira, Moraes, Lara, & Nogueira, 2017).…”

Low base saturation (V) is one of the major abiotic stresses in the Brazilian Cerrado. Given this scenario, it is important to evaluate different physiological responses of genotypes in environments with and without liming aiming at select both liming responsive and low‐saturation tolerant genotypes. The hypothesis of this study is that contrasting V conditions provide changes in physiological performance of soybean genotypes. Thus, our objective was to select soybean genotypes in environments with recommended and low V. Two field experiments were carried in randomized block design with three replicates and 10 F3 soybean genotypes (P1, P2, P3, P4, P5, P6, P7, P8, P9 and P10). In the first experiment, genotypes were evaluated without V correction (V = 30%), while in the second experiment, a liming was performed three months before to raise V to 60%. The traits evaluated were as follows: calcium and magnesium contents, days for maturation, transpiration, net photosynthesis, stomatal conductance and internal CO2 concentration. Our findings indicate that the physiological performance of soybean genotypes depends on the saturation condition. The P9 genotype obtained the best physiological performance under recommended V and can be used to obtain F3:4 lines physiologically responsive to soil correction. The P5 genotype obtained the best physiological performance at low V and can be used to obtain F3:4 lines aiming at a higher tolerance to low saturation. Considering that the Brazilian soils, especially in the Cerrado, are mostly poorly fertile, our study provide crucial information for soybean breeding programmes aiming at selecting genotypes tolerant to limiting environmental conditions.

“…The latter is being the most used although criticized for the linearity between the soil pH and the limestone total neutralizing power (TNP) (Teixeira et al, 2020). Although the most common practice for acidity correction is liming, the application of Ca and Mg silicate in place of limestone has been carefully studied with satisfactory results (Deus et al, 2020).…”

The study aimed to measure the variation in the values of pH, P, K, Ca, Mg, Al, H+Al, V, and Ca and Mg saturation after limestone and silicate applications as a function of different soil correction methods and incubation periods under a controlled environment. The research was carried out in a greenhouse at the FCA of the Federal University of Grande Dourados (UFGD). The experiment was completely randomized in a factorial scheme (5 × 3 × 5), with four replications. The main factors consisted of five incubation times: 0, 30, 60, 90, and 120 days; three soil classes: dystrophic Red Latosol (LVd), Dystroferric Red Latosol (LVdf), and dystrophic Gray Argisol (PACd); and five soil acidity correction methods: control, Ca/Mg balance for limestone and silicate, and 50% and 70% base saturation. Chemical analysses were performed after each incubation period. A regression analysis was carried out once a significant difference was observed between the means of the main factors of the analysis of variance, being adjusted to quadratic models for pH, P, Al, K, Ca, Mg, H+Al, and V. Statistical analyses were performed in the AgroStat software. The ideal soil incubation time to reach the maximum efficiency of correction of the chemical attributes of LVd, LVdf, and PACd soils by the studied methods ranges from 78 to 86 days. The application of limestone by balance of 60% Ca and 20% Mg and calcium and magnesium silicates achieved the best correction indexes of soil chemical attributes, enabling the proposed equation as a calcium and magnesium silicate calculation.

“…Several studies have shown that soil acidity in NTS can be controlled by applying lime to the surface without incorporation (Bossolani, dos Santos, et al., 2020; Caires et al., 2006, 2015; Carmeis Filho et al., 2017; Crusciol et al., 2016; Deus et al., 2020; Tiritan et al., 2016). Lime particles that descend through porous channels formed by the roots of plants are able to correct soil acidity in deeper layers (Tiritan et al., 2016).…”

Exploring the synergism between surface liming and nitrogen fertilization in no‐till system

Surface liming to correct soil acidity may have limited effectiveness in subsurface layers in no-till systems (NTS). The possibility of downward movement may be increased when liming is combined with fertilization with urea (ammoniacal N), as NO 3 formed by nitrification of NH 4 + can form ion pairs with exchangeable Ca 2+and Mg 2+ . Liming can also increase the nitrogen use efficiency (NUE) of crops and reduce dependence on soil N. In this work, we investigated the effects of surface application of lime under NTS and N topdressing on soil chemical properties and the nutrition, productivity, and NUE of maize (Zea mays L.) and upland rice (Oryza sativa L.). The treatments comprised four lime rates applied superficially (0, 1,500, 3,000, and 6,000 kg ha -1 ), and absence (-N) or presence of N fertilization (+N) as urea by topdressing. The treatments were applied during two agricultural years (2011/2012 and 2012/2013), with maize in the first crop season and upland rice in the second crop season. At 18 mo after liming, the application of 6,000 kg lime ha -1 significantly improved the chemical attributes of the soil (pH, soil organic matter (SOM), K, Ca 2+ , Mg 2+ , and base saturation [BS]). The application of urea increased the mobility of Ca 2+ and Mg 2+ to greater depths. The combination of 3,000 kg lime ha -1 with N fertilization synergistically increased the nutrition (N, P, and S), grain yield, and N-related efficiency indexes in the maize and upland rice crops.
