“…A decrease in the doses led to values of 2.13 g kg -1 and 2.10 g kg -1 with respect to the 40 kg ha -1 and 0 kg ha -1 doses, respectively. An explanation for this behavior is the same as that used for soybean crop in which higher Mg levels in corn leaves were observed in the plots that received phosphate fertilization due to increased availability of P to the plants since phosphorous is an important factor for mobilization, absorption, and translocation of Mg into a plant (ZHONG; SCHOBERT; KOMOR, 1993).…”

“…However, increases in corn yield by using gypsum without water deficit were observed in studies by and Zandoná et al (2015). Nevertheless, several studies did not indicate responses to gypsum applied in soybeans (CAIRES et al, 1998;2003;NEIS et al, 2010;RAMPIM et al, 2011;MODA et al, 2013).…”

“…However, the sole use of this correction practice is strongly questioned since superficial liming without soil revolving (as recommended in the no-tillage system) limits the corrective effect of limestone to the superficial layers (CAIRES et al, 2003). This situation requires the use of soil conditioners, such as agricultural gypsum, to neutralize aluminum and provide calcium in depth (OLIVEIRA et al, 2009;ZANDONÁ et al, 2015). The high levels of Al + 3 and the reduction of exchangeable bases in the deeper soil layers was indicated as limiting parameters of root development and consequently a decrease in crop yield (MATTIELLO et al, 2008;NORA et al, 2014).…”

-The objective with this work was to evaluate the effect of the agricultural gypsum, associated with phosphate fertilization, on the nutrition, development and yield of soybean and corn in succession, under no-tillage system. The experiment was conducted at Universidade Federal de Goiás, Regional Jataí, in a randomized blocks design 5x3 factorial arrangement, with 4 replicates. The first factor consisted of the gypsum doses (0, 1, 2, 4 and 8 Mg ha-1) and the second the phosphorus doses (0, 50 and 100% of the recommended dose). Leaf nutrient contents, leaf area index, SPAD index, dry plant mass, final plant population, one thousand grain mass and grain yield were evaluated in the crops. In the soybean, the number of pods was also obtained and in the corn the average ear length, number of rows per ear, number of grain per ear and number of ears. Phosphorus doses increase leaf Mg contents in soybean and corn. The application of gypsum reduces the Mg and K leaf contents and increases the Ca, S, and Mn contents in the two cultures. Gypsum provides increases in the SPAD index in soybean plants. The unbalance of the N / K ratio in corn leaves, provided by the increase of the gypsum doses, reduces the leaf area of this crop. Doses of P and gypsum do not influence the yield of soybeans and maize.

RESUMOO estudo da distribuição de nutrientes no perfil do solo é um método adequado para se detectar a influência dos sistemas de manejo do solo na aplicação de corretivos, bem como para avaliar o seu efeito na nutrição das plantas. Assim, objetivou-se avaliar os sistemas de manejo do solo e a aplicação de calcário e gesso sobre os atributos químicos do solo e a produtividade da cultura do milho. O experimento de campo foi realizado em um Latossolo Vermelho Distrófico típico no delineamento de blocos casualizados, no esquema fatorial, com quatro repetições, sendo cultivo convencional, mínimo e semeadura direta e a aplicação de calcário ou calcário e gesso. Foram realizadas análises químicas do solo e foliares da cultura do milho, bem como determinado a produtividade de grãos. Observou-se que os atributos químicos do solo, a nutrição mineral e a produtividade de grãos da cultura do milho sofreram influência dos sistemas de manejo, sendo que o tratamento utilizando cultivo convencional associado à aplicação de calcário e gesso agrícola apresentou os melhores resultados, indicando a necessidade da incorporação do corretivo para a recuperação do solo sob pastagem degradada. PALAVRAS-CHAVE: ausência de preparo; calcário; cultivo convencional; cultivo mínimo; gesso agrícola. SOIL CHEMICAL ATTRIBUTES AND CORN PRODUCTIVITY CULTIVATED WITH SOIL CORRECTIVES APPLICATION AND SOIL MANAGEMENT SYSTEMSABSTRACT The nutrients distribution study on the soil profile is an appropriate method to detect the influence of soil management systems in the correctives application, as well as to evaluate its effect on plant nutrition. Therefore, the aim of this study was to evaluate both the effect of soil management systems and the correctives application on soil chemical properties and grain yield of corn. A field experiment in a randomized split-plot, with four replications, installed on a Hapludox clay soil under conventional tillage, minimum tillage and no-tillage, with liming and gypsum application or just liming, was performed. Soil chemical analysis and foliar chemical analysis were performed, as well as the determination of corn grain yield. It was

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.
