“…In this case, gypsum contributed to the increase in SMB, and it may have caused changes in the dry biomass production of millet, unlike the results obtained by Carvalho & Nascente (2014), who reported that the gypsum application did not change the dry biomass production of millet. The use of agricultural gypsum has provided large increases in yield.…”

The objective of this work was to evaluate soil biomass and microbial activity and soybean yield under different limestone and gypsum doses and different cover crops. The experiment was carried out in the experimental area of the Fundação de Apoio a Pesquisa Agropecuária de Chapadão, on a Dystrophic Red Latosol, using cultivar Desafio. The experiment consisted of a randomized blocks design, in a split-plot factorial scheme (3x4x3), with three replications. Plots consisted of three gypsum doses: control (without gypsum), recommended dose (2.3 Mg ha-1), and double dose (4.6 Mg ha-1). Subplots consisted of four limestone doses (2, 4, and 6 Mg ha-1) and the control (without limestone). Each block had three different cover crops: Brachiaria, Millet, and allow. The values obtained with the test revealed that brachiaria had better basal respiration in the absence of gypsum. Conversely, millet had better basal respiration in with the gypsum dose. Basal respiration, using brachiaria as cover crop, was higher at the dose of 2700 kg ha-1 of limestone. However, for the fallow and the millet, basal respiration was higher when using the highest limestone dose of 6000 kg ha-1. The variable microbial biomass showed differences between cover crops only in the absence of gypsum. Brachiaria and fallow presented the highest mean for microbial biomass. The use of millet as a cover crop together with gypsum doses increased the microbial biomass. The variables mass of 100 grains and grain yield had higher mean at the limestone dose of 6000 kg ha-1 .

“…Liming brought improvements to the production of bean cultivars and gypsum reduced panicles in rice and number of pods in beans, but did not affect the productivity of both (Soratto, Crusciol, & Mello 2010). The application of limestone increased the productivity of soybean, corn (Joris et al, 2013;Pauletti et al, 2014), black oat (Pauletti et al, 2014) and increased dry biomass of millet (Carvalho & Nascente, 2014). Note.…”

“…ANOVA for the characteristics evaluated in soybean indicated a significant effect on plant height (PH) due to acidity management (AM) and the interaction between incorporation and acidity management was significant in the number of pods per plant (NP) and in crop yield (PROD). Significant effects on productivity components were observed in the cultivation of rice and beans (Soratto, Crusciol, & Mello, 2010), wheat (Rampim et al, 2011;Pauletti et al, 2014), millet (Carvalho & Nascente, 2014), black oats (Pauletti et al, 2014), corn and soybeans (Joris, Caires, Bini, Scharr, & Haliski, 2013;Pauletti et al, 2014;Zandoná et al, 2015) and angico and canafístula (Vargas & Marques, 2017).…”

The soils of Brazilian Savanna, naturally, present acidity problems, making correction practices fundamental to ensure production. Even with so many years since the introduction of agriculture, some soil correction practices are still misused. Thus, the objective was to evaluate soybean yield and chemical changes in a Red Oxisol in the Brazilian Savanna with the use of limestone, associated or not with gypsum, applied superficially and incorporated by harrow and moldboard plow. The experiment was conducted under field conditions, in Rio Verde-GO, cultivating soybeans in the 2015/2016 and 2016/1017 harvests. The experimental design was in randomized blocks, with four replications, with treatments arranged in a 3 × 3 factorial scheme. The first factor refers to the application of superficial limestone and incorporated by harrow and moldboard plow. The second factor was the presence or absence of limestone and/or gypsum (0 + 0; 0.875 + 0 and 0.875 + 1.75 t ha-1). Plant height, number of pods per plant, productivity, pH, Al, CTC, Ca, Mg and V were evaluated, in soil depths of 0-0.2 and 0.2-0.4 m. In the 2016/2017 harvest, the characteristics of pH, CTC, V and contents of Ca, Mg and Al were influenced by the methods of application of limestone and by its use, associated or not with gypsum. There was an increase in pH on the soil surface with the use of limestone and on the subsurface with the use of limestone and gypsum. The moldboard plow provided increases in the contents of Ca and Mg in the soil in comparison to surface application. The moldboard plow incresed in soybean yield, in the second crop, with and without association of gypsum with limestone.

“…Isso comprova o baixo período residual destes produtos, especialmente nos solos arenosos, que possuem poder tampão reduzido e baixa fertilidade natural (CAIRES et al, 2003). Ainda, a baixa granulometria do calcário e do silicato, bem como a lixiviação de bases são apontadas como possíveis causas para o baixo período residual destes produtos (QUAGGIO et al, 1982;SILVA et al, 1980;CARVALHO & NASCENTE, 2014). A semelhança no desenvolvimento de aveia preta nos tratamentos testemunha com e sem aplicação dos corretivos de acidez, podem ser justificadas pelo fato da calagem ser capaz de corrigir a acidez do solo, não sendo capaz de disponibilizar nutrientes como o fósforo (NOLLA & ANGHINONI, 2006).…”
