“…Magnesium concentrations decreased linearly with increasing PG application rates in the 0.0-0.1 and 0.1-0.2 m layers, as reported in other studies (Toma et al, 1999;Soratto and Crusciol, 2008;Caires et al, 2011a), and again no effect of splitting was observed.…”

“…The combination of these variations resulted in a statistical difference for the Ca/Mg ratio among split treatments. A Ca/Mg increase in response to PG application rates was also reported by Caires et al (2011a), attributing these results to increases in Ca 2+ concentrations and Mg 2+ leaching.…”

“…Due to its solubility and other specific reaction characteristics, PG (CaSO 4 .2H 2 O) moves throughout the soil profile releasing Ca 2+ and sulfur (S) (Caires et al, 2006(Caires et al, , 2011aSoratto and Crusciol, 2008). Concomitantly, Mg 2+ and K + -the latter only rarely -are displaced from the soil exchange sites in top layers and then move along with water to the subsurface (Caires et al, 2011b to plant roots can occur (Toma et al, 1999), due to the formation of ionic pairs between Al 3+ and the sulfate (SO 4 2− ) or fluoride (F − ) contained in PG (Zambrosi et al, 2007).…”

ABSTRACT:Applications of phosphogypsum (PG) provide nutrients to the soil and reduce Al 3+ activity, favoring soil fertility and root growth, but allow Mg 2+ mobilization through the soil profile, resulting in variations in the PG rate required to achieve the optimum crop yield. This study evaluated the effect of application rates and splitting of PG on soil fertility of a Typic Hapludox, as well as the influence on annual crops under no-tillage. Using a (4 × 3) + 1 factorial structure, the treatments consisted of four PG rates (3, 6, 9, ) and three split applications (P1 = 100 % in 2009; P2 = 50+50 % in 2009 and 2010; P3 = 33+33+33 % in 2009, 2010 and 2011), plus a control without PG. The soil was sampled six months after the last PG application, in stratified layers to a depth of 0.8 m. Corn, wheat and soybean were sown between November 2011 and December 2012, and leaf samples were collected for analysis when at least 50 % of the plants showed reproductive structures. The application of PG increased Ca 2+ concentrations in all sampled soil layers and the soil pH between 0.2 and 0.8 m, and reduced the concentrations of Al 3+ in all layers and of Mg 2+ to a depth of 0.6 m, without any effect of splitting the applications. The soil Ca/Mg ratio increased linearly to a depth of 0.6 m with the rates and were found to be higher in the 0.0-0.1 m layer of the P2 and P3 treatments than without splitting (P1). Sulfur concentrations increased linearly by application rates to a depth of 0.8 m, decreasing in the order P3>P2>P1 to a depth of 0.4 m and were higher in the treatments P3 and P2 than P1 between 0.4-0.6 m, whereas no differences were observed in the 0.6-0.8 m layer. No effect was recorded for K, P and potential acidity (H+Al). The leaf Ca and S concentration increased, while Mg decreased for all crops treated with PG, and there was no effect of splitting the application. The yield response of corn to PG rates was quadratic, with the maximum technical efficiency achieved at 6.38 Mg ha -1 of PG, while wheat yield increased linearly in a growing season with a drought period. Soybean yield was not affected by the PG rate, and splitting had no effect on the yield of any of the crops. Phosphogypsum improved soil fertility in the profile, however, Mg 2+ migrated downwards, regardless of application splitting. Splitting the PG application induced a higher Ca/Mg ratio in the 0.0-0.1 m layer and less S leaching, but did not affect the crop yield. The application rates had no effect on soybean yield, but were beneficial for corn and, especially, for wheat, which was affected by a drought period during growth.

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

et al. 2020

View full text Add to dashboard Cite

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.

Soil acidity (pH <4.4) restricts exploration by the root system and impairs crop yield. To contribute to the development of alternative methodologies for correcting acidity in the surface and subsurface layers of soil, the present study evaluated the effects of seven combinations of application technique (surface, incorporation under soil tillage, or subsurface) and calcium (Ca) compounds (limestone [LS], phosphogypsum [PG], and hydrated lime [HL]) on soybean [Glycine max (L.) Merr.] and maize (Zea mays L.) grain yields and on the absorption of macronutrients and dry matter yield of palisade grass (Urochloa brizantha syn. Brachiaria brizantha ‘Marandu’) in a Typic Hapludalf in an agropastoral system in Brazil. The experimental design was randomized complete blocks with four replications. The results support the following conclusions: (a) applying HL plus PG is a viable alternative to applying LS plus PG for soybean and maize crops, (b) incorporating LS by plowing and harrowing is not a viable alternative to applying LS on the surface, (c) applying HL plus PG on the subsurface is superior to applying HL plus PG on the surface for soybean and palisade grass cultivation, (d) incorporating LS plus PG followed by annually applying LS on the surface improves palisade grass crop yield, (e) annually applying LS plus PG 2 yr before and annually applying LS plus PG increase palisade grass crop yield, and (f) annually applying LS or HL plus PG increases the absorption of Mg and S by palisade grass.
