“…Without water deficiency, soybean had a low probability of responding to gypsum (37%), and the probability of crop yield increasing more than 5% in soils with Al saturation >40% was only 20% (Figure 9d).

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.

“…In several Brazilian regions, such practices have been satisfactory, when established based on soil analysis and all activities that complement them, followed strictly and efficiently. A soil management system therefore has the purpose of preparing the area for planting crops with efficiency capable of absorbing good results both for the soil and for production through the conditions of a healthy soil and satisfactory growth and development of plants (Freitas et al, 2016).…”

Liming is the method in which limestone is applied to regulate the pH of the soil reducing its acidity and making the minerals labile. This study aimed to evaluate the management of liming using dolomitic limestone in sandy textured soils, on the development of soybean cultivation through a bibliographical survey. Sandy soil also, known as “light soil” is largely composed of sand and a smaller proportion of clay around 70% and 15% respectively, its grain size is higher, and the presence of nutrients is very scarce. Correcting soil acidity through liming is the first step towards obtaining a considerably productive crop, especially in recently cleared areas. Since in acidic soils, the limitation to plant development arises mainly from the indirect effects of pH. Therefore, it is necessary to analyze the soil continuously as well as the weather conditions in order to obtain the desired result. Several results have been observed in which the use of liming in acidic soils, mainly in the Brazilian Cerrado, reduces the toxic action of aluminum on the plant and promotes greater absorption of nutrients and micronutrients for the plants, in addition to maintaining the soil microbiota.
