“…The linear increase in the S-SO 4 2− levels in soil layers was also found in other studies, up to 0.6 m depth (Caires et al 2011a;Michalovicz et al 2018). SO 4 2− is supplied by the gypsum but is weakly retained in the soil and tends to mobilize deeper into the soil profile, through the action of water and gravity, especially in NT, due to the accumulation of organic matter (OM) in the soil surface layers.…”

“…Once the net charge of the resulting complex is lower (e.g. [AlSO 4 ] + ), mobilization of aluminum to deeper soil layers may occur, consequently reducing the toxicity to the plant roots (Michalovicz et al 2018).…”

“…The increase and the balance between Ca 2+ and Mg 2+ levels deeper in the soil after gypsum application are linked to the ion pairings with SO 4 2− (Michalovicz et al 2018), along with the complexation with organic acids from the decomposition of crop residues (Franchini et al 2003). The application of 12 Mg ha −1 , especially when combined to 2S and 3S splitting, resulted in Ca/Mg ratios that surpassed the optimum in the upper soil layers (0-0.4 m depth), which is 6:1 for corn yield (Osemwota et al 2007), and these results are in agreement with other studies (Caires et al 2004;Michalovicz et al 2018).…”

Gypsum is used in agriculture as calcium (Ca 2+) and sulfur (S) source, and to mitigate native toxic levels of aluminum (Al 3+). However, the effects on soil chemical attributes, corn leaf nutritional status, grain yield, and profitability should be better understood. Gypsum rates (0, 3, 6, 9, and 12 Mg ha −1) were applied at once (2009) or split in two (2009-2010) or three (2009-2010-2011) annual applications, to a Typic Hapludox under no-till from Southern Brazil. The use of gypsum increased Ca 2+ and S-SO 4 2− and reduced Al 3+ levels in the soil up to 0.8 m depth. Increasing gypsum rates reduced Mg 2+ levels up to 0.6 m. Corn leaf concentrations of Ca and S were increased, while Mg concentration was decreased by gypsum use. The maximum technical efficiency (MTE) rate of gypsum for corn (2013/2014) grain yield was 6.34 Mg ha −1. The most profitable rate for the period 2009-2014 growing seasons was achieved with 4.60, 5.63, and 6.08 Mg ha −1 of gypsum applied at once or split in two and three annual applications, respectively. The use of gypsum within the MTE interval improves chemical attributes in the soil profile, corn leaf nutritional status, corn grain yield, and land use profitability. The use of gypsum causes soil Mg 2+ leaching. Split application reduces leaching process for S-SO 4 2− , but not for Mg 2+ .

“…The experiment was conducted in a field at Guarapuava, Paraná State, Brazil (25°23′ S, 51°30′ W, altitude 1026 m), under humid subtropical mesothermic climate (Cfb) (Alvares et al 2013). The soil of the experiment site was classified (Michalovicz et al 2018) as a very clayey Typic Hapludox (USDA 1999).…”

The residual effects of gypsum rates and the interaction with N-fertilization on soil fertility, black oat root growth and aboveground biomass yield under no till lacks information. This study evaluated soil chemical attributes up to 0.8 m depth and aboveground biomass of black oat in a continuous no-till area as affected by gypsum rates (0, 3, 6, 9 and 12 Mg ha −1) and topdressing N-fertilization (0, 50 and 100 kg ha −1) to a Typic Hapludox in Southern Brazil. Black oat root growth was also evaluated for two gypsum rates (0 and 6 Mg ha −1) and all N treatments. Gypsum application increased Ca 2+ and SO 4 2 −-S fraction and reduced Mg 2+ levels in all soil layers, and N-fertilization increased NO 3 − and NH 4 + levels in the soil. Gypsum increased root length, superficial area and volume up to 0.8 m depth, while N-fertilization reduced root growth attributes in soil layers between 0.4 and 0.8 m depth. Gypsum increased (quadratically) the aboveground biomass yield of black oats in the two growing seasons, as did N-fertilization, but no interaction between gypsum and N-fertilization was observed. Gypsum can be used to improve soil fertility attributes, black oat biomass and root growth under no till. The higher N-fertilization (100 kg ha −1) increased black oat yield and reduced root growth in depth. In the average of the growing seasons, the gypsum rate of 7.36 Mg ha −1 applied 54 months earlier, associated with a rate of at least 50 kg ha −1 of N (urea) applied at the beginning of black oat tillering achieved the higher aboveground biomass yield.

“…Consequently, gypsum reduces Al 3+ activity and provides Ca 2+ and SO4 2in deepest layers of the soil, stimulating growth of roots in depth, which results in greater tolerance of plants to water deficit stress. However, high-dose agricultural gypsum changes availability of nutrients in the soil and may influence the nutrient uptake by plant (Michalovicz et al, 2019;Rampim, Lana, Frandoloso, & Fontaniva, 2011;Ritchey & Sousa, 1997;Sousa, Lobato, & Rein, 2005;Vicensi et al, 2016). Thus, gypsum may affect accumulation of macronutrients and micronutrients in root and shoot of trifoliate orange plants.…”

Use of trifoliate orange [Poncirus trifoliata (L.) Raf.] as a rootstock has intensified in recent years in Brazil. Objectives of this study were to evaluate the effects of lime and agricultural gypsum on concentration of nutrients in trifoliate orange. Seedlings of trifoliate orange were grown in PVC pipe columns, presenting 15 cm in diameter and 35 cm in length. The columns were sectioned in two rings: the upper ring, 15 cm high, and the lower ring, 20 cm high. The factorial scheme (2×4)+1 was used, being two liming treatments and four agricultural gypsum doses (carried out only in the soil of the upper ring), and an additional treatment (with liming carried out in the soil of both upper and lower ring). Liming increased Mg and S concentrations in roots of the superficial soil layer (0-15 cm). Ca concentration was higher in roots of both superficial (0-15 cm) and subsuperficial (15-35 cm) layers. Gypsum without liming resulted in higher N, K, and Mn concentrations and lower Mg concentration in roots of the soil subsurface layer. Ca and S concentrations in root of the soil superficial layer were higher with gypsum. In plant shoot, the concentrations of K, Ca, S and Cu were higher with liming, and concentrations of Ca and P were higher and lower, respectively, with gypsum application.
