Resumo: | Studies that evaluate the crop responses to the soil modifications intermediated by gypsumapplication are relatively abundant, but most of them are performed in highlands. Such studies are still scarce in lowlands. The objective of our study was to evaluate soil acidity and phosphorus (P) and potassium (K) availability, as well as crop (irrigated rice and soybean) yields, as a function of different rates of gypsum application in lowland. The experiments were conducted in a Planosol (Triunfo, Rio Grande do Sul, Brazil). The treatments consisted of six gypsum rates (0.00, 0.25, 0.50, 1.00, 2.00 and 4.00 t ha-1) and the experimental design was in randomized blocks with four replications. The soil was sampled after crop harvests, in the 0–5, 5–10, 10–20 and 20–40 cm layers. The soil pH (in water), the potential acidity (H+Al) and the available P (Mehlich 1) were not affected by gypsum application. After the irrigated rice cropping and in the soil layer of 0–5 cm, the available K (Mehlich 1) contents was impacted by the gypsum application, with increase in content for rates up to 1.00 t ha-1 and decrease in content for higher rates (2.00 and 4.00 t ha-1). After the soybean cropping, the available K content was not affected by gypsum application. The gypsum application did not impact irrigated rice and soybean yields in the evaluated season, which did not present water deficit. |

Este trabalho objetivou avaliar a acidez e a disponibilidade de fósforo (P) e potássio (K) do solo e a produtividade do arroz irrigado e da soja, cultivados em terras baixas, com aplicação de doses de gesso agrícola. Os experimentos foram conduzidos em um Planossolo Háplico (Triunfo/Rio Grande do Sul). Os tratamentos consistiram em seis doses de gesso agrícola (0,00; 0,25; 0,50; 1,00; 2,00; e 4,00 t ha-1) e o delineamento experimental foi o de blocos casualizados. O solo foi coletado após a colheita das lavouras, nas camadas de 0–5, 5–10, 10–20 e 20–40 cm. O pH em água, a acidez potencial (H+Al) e o P disponível (Mehlich 1) não foram alterados com a aplicação de gesso agrícola. Após o cultivo de arroz irrigado e na camada de 0–5 cm, houve aumento do teor de K disponível (Mehlich 1) para doses até 1,00 t ha-1 e diminuição do teor para doses maiores (2,00 e 4,00 t ha-1). Após o cultivo de soja, o teor de K disponível não foi alterado com a gessagem. A aplicação de gesso agrícola não influenciou a produtividade do arroz irrigado e da soja na safra avaliada, onde não houve déficit hídrico.Departamento de Diagnóstico e Pesquisa Agropecuária.
