“…This is especially apparent in soils containing little organic matter to bind Al and reduce its activity in the soil solution as a result (Bortoluzzi et al, 2014;Joris et al, 2016). The application of gypsum to soils with a low subsoil Al saturation (<10%) caused a slight decrease in soybean yield (0.3% on average; Figure 6), consistent with the results of Pauletti et al (2014) and Somavilla et al (2016). Based on the critical thresholds for soybean (Al saturation >10% under water-deficient conditions), the probability of this crop responding in a negative manner to gypsum was 40%.…”

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).

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

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.

“…The results of research along this line, however, are contrasting and differ largely according to crop, climate, and initial conditions of the cropland. Thus, some authors reported a large increase in crop yield (Dalla Nora and Amado, 2013; Caires et al, 2016), whereas others observed no appreciable change (Vidigal et al, 2014;Somavilla et al, 2016) and still others found that gypsum reduced yields (Fontoura et al, 2012;Pauletti et al, 2014;Somavilla et al, 2016). Although the effects of gypsum on soil chemical properties are well known, the specific conditions for a favorable effect on crop yield and precise recommendations for usage, remain to be established (Caires et al, 2011b;Dalla Nora and Amado, 2013;Vicensi et al, 2016).…”

The use of gypsum to improve the root environment in tropical soils in the southeastern and central-western regions of Brazil is a widespread practice with well-established recommendation criteria. However, only recently gypsum began to be used on subtropical soils in South of Brazil, so available knowledge of its effect on crop yield is incipient and mainly for soils under no-till (NT) systems. Avaiable studies span a wide range of responses, from a substantial increase to a slight reduction in crop yield. Also, the specific conditions leading to a favorable effect of gypsum application on crop yield are yet to be accurately identified. The primary objectives of this study were to examine previously reported results to assess the likelihood of a crop response to gypsum and to develop useful recommendation criteria for gypsum application to subtropical soils under NT in Brazil. For this purpose, we examined the results of a total of 73 growing seasons, reported in 20 different scientific publications that assessed grain yield as a function of gypsum rates. Four different scenarios were examined, by the occurrence or not of high subsurface acidity (viz., Al saturation >20 % and/or exchangeable Ca <0.5 cmol c dm-3 in the 0.20-0.40 m soil layer) and of water deficiency during the crop cycle. Based on the results, for grasses, 10 % Al saturation and/or 3 cmol c dm-3 exchangeable Ca in the soil subsurface layer (0.20-0.40 m) is more suitable than the current recommendation (Al saturation of 20 % and/or 0.5 cmol c dm-3 Ca) for subtropical NT soils in Brazil. Also, applying gypsum to NT soils with low subsurface acidity (Al saturation <10 %) and with an adequate Ca content (>3 cmol c dm-3) failed to increase crop yield, irrespective of the soil water status. Under these conditions, high gypsum rates (6-15 Mg ha-1) may even reduce grain yield, possibly by inducing K and Mg deficiency. On the other hand, applying gypsum to soils with high subsurface acidity increased yield by 16 % in corn (87 % of cases) and by 19 % in winter cereals (83 % of cases), whether or not the soil was water-deficient. By contrast, soybean yield was only increased by gypsum applied in the simultaneous presence of high soil subsurface acidity and water deficiency (average increase 27 %, 100 % of cases).

Under continuous no-till, gypsum has been successfully used to manage soil fertility and improve crop yield. Nitrogen (N) fertilization is critical for crop performance, however, since it is expensive and potentially pollutant, it must be correctly applied. Both subjects have been widely studied, yet there is a lack of information on the interaction between them, especially concerning crops in rotation or succession. The objectives of this study were to evaluate topdressing N fertilization (0, 50, and 100 kg N ha −1 ) on black oat (Avena strigosa Schreb.) under no-till, inside a long-term gypsum experiment (0, 3, 6, 9, and 12 Mg ha −1 ). We evaluated black oat regrowth after haylage harvest and nutrient concentration and uptake by aboveground biomass, as well as the effects of this system on the successor crop soybean (Glycine max (L.) Merr.) in terms of leaf nutrient concentration and grain yield over two growing seasons. The gypsum application, even up to 44 and 55 months earlier, presented a long-term effect when associated with N fertilization, causing black oat biomass to increase during the regrowth phase. Nitrogen fertilization increased black oat regrowth biomass, even without gypsum. Greater nutrient uptake by black oat regrowth occurred under higher gypsum rates and N fertilization, which may have been advantageous in the long term for the production system, once nutrient cycling may partially substitute fertilizer-derived nutrients. Soybean yield was not affected by either long-term gypsum or N applied at black oat tillering, even though some leaf nutrient concentrations were influenced.
