“…As confirmed by the regression tree analysis, gypsum rates >6 Mg ha −1 led to the greatest cereal yields ( Figure 6). This result confirms the linear relationship between gypsum rate and cereal grain yield previously observed in some crops grown on soils with a high Al saturation in the subsoil (Dalla Nora et al, 2017b;Michalovicz et al, 2014;Tiritan et al, 2016). Although the higher gypsum rates resulted in greater increases in grain yield, the crops responded highly variably to gypsum, so the gypsum rate to be used in each case should be established with caution.…”

“…The solid line inside the rectangle represents the median, the dotted line represents the mean, and vertical lines above and below the box extend to the minimum and maximum values, respectively. The mean effect of gypsum application on crop grain yield (Y) is shown above the box plot, and the number of pair observations (n) used to calculate the mean effect is shown at the bottom shown the positive effects of gypsum application on crop grain yield to be stronger under water-deficient conditions (Pauletti et al, 2014;Somavilla et al, 2016;Tiritan et al, 2016). However, water deficiency was present only in 19% of the studies included in this meta-analysis (Figure 1f).…”

“…Nitrogen in well-aerated tropical and subtropical soils is present mainly as NO 3 − , which is readily leached to the subsoil . The more efficient use of available N resulting from gypsum application to an acid subsoil was less marked with soybean because this crop obtains almost all the N it requires by biological fixation Tiritan et al, 2016). In addition, cereal roots usually have a lower root CEC than soybean (Caires, Joris, & Churka, 2011a;Caires et al, 2011b) and hence a lower capacity to absorb cations present at low concentrations in soil (Pauletti et al, 2014;Tiritan et al, 2016).…”

As a result, the increase in soybean grain yield by the effect of gypsum application was small relative to the cereals and was more limited in the soils with increased Al saturation (>10 and 40% in the presence and absence, respectively, of water deficiency) relative to those bearing the cereals (Al saturation >5%) (Figure 7).…”

“…Although the higher gypsum rates resulted in greater increases in grain yield, the crops responded highly variably to gypsum, so the gypsum rate to be used in each case should be established with caution. Also, high gypsum rates should be applied in combination with liming to prevent Mg 2+ deficiency in the soil surface (Caires, Chueiri, Madruga, & Figueiredo, 1998;Costa & Crusciol, 2016;Soratto & Crusciol, 2008a) and, especially, to neutralize soil acidity in the medium to long term (Bortoluzzi et al, 2014;Fontoura et al, 2019;Joris et al, 2016: Tiritan et al, 2016. In fact, Dalla Nora et al (2017) found gypsum to have more beneficial effects on the subsoil when soil surface acidity was neutralized by liming.…”

Does gypsum increase crop grain yield on no‐tilled acid soils? A meta‐analysis

et al. 2020

Improving the chemical conditions for plant growth in the subsoil is especially difficult in no-till (NT) soil because of the low solubility of limestone. In this situation, gypsum may be recommended due to its ability to mobilize exchangeable Ca 2+ and other basic cations associated with SO 4 2− anions mainly in the soil profile, thereby alleviating Al toxicity. However, the response of crops to gypsum is contradictory and ranges from a substantial increase to a slight decrease in grain yield. In this work, a meta-analysis comprising 129 harvests of six different grain crops (930 observation pairs in all) was conducted to identify the conditions under which grain yield responds to gypsum and to establish criteria for optimal management of gypsum as an amendment for NT soils. Based on the results, cereals (maize [Zea mays L.], wheat [Triticum aestivum L.], white oat [Avena sativa L.], barley [Hordeum vulgare L.], and rice [Oryza sativa L.]) have a high probability (77-97%) of their grain yield being increased by gypsum application to soils, with Al saturation exceeding 5% in the 0.20to 0.40-m layer. The average increase in grain yield was 14 and 7% in crops growing in the presence and absence of water deficiency, respectively. A positive response of soybean [Glycine max (L.)Merr.] to gypsum was observed in water-deficient soils with Al saturation exceeding 10%. Under these conditions, the probability of a positive response of soybean was 88%, and the average yield increase was 12%. Therefore, gypsum application decreases Al toxicity to plants and increases crop grain yields as a result in NT soils with high Al saturation.

An experiment was conducted in the greenhouse facilities of Embrapa Maize and Sorghum to evaluate the limestone reaction in sandy soil based on rates, limestone type, effective calcium carbonate equivalent (ECCE), and moisture regime over time. A factorial design of 4 × 2 + 3 was adopted, consisting of four limestone rates with 76% ECCE (0, 1, 2, and 4 Mg ha−1), two irrigation types (daily and monthly, simulating constant and intermittent moisture regime), and three additional treatments (three rates of “filler” limestone—99% ECCE—under monthly irrigation). Soil chemical characteristics were analyzed at 1, 2, 3, 6, and 12 months after treatment application. Soil fertility improved at the first month after treatment application, with emphasis on higher limestone rates, monthly moisture regime, and filler lime stone. The highest limestone rate did not increase the pH above 7.0. The recommended limestone rate was insufficient to elevate Ca + Mg levels to the adequate level for current production genotypes and systems, which demand higher standards. These outcomes reinforce the need for carrying out further studies and potential revision in liming recommendations for sandy soils.

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

et al. 2022

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.
