soil reaction
[/sɔɪl rɪˈækʃən/]
nounpl: soil reactions
reação do solo
1. The degree of acidity or alkalinity of soil, typically measured on the pH scale, ranging from 0 to 14, where 7 is neutral
The soil reaction in this agricultural field is slightly acidic, with a pH of 6.5.
A reação do solo neste campo agrícola é ligeiramente ácida, com pH de 6,5.
2. The chemical properties of soil that determine its pH level and affect nutrient availability for plants
Farmers test soil reaction to determine what amendments are needed for crop cultivation.
Os agricultores testam a reação do solo para determinar que correções são necessárias para o cultivo de colheitas.
3. The response of soil chemistry to environmental factors and agricultural practices
Continued liming altered the soil reaction, making it more suitable for crops requiring neutral conditions.
A aplicação contínua de calcário alterou a reação do solo, tornando-o mais adequado para culturas que requerem condições neutras.
Soil reaction is a fundamental concept in both Brazilian and American agriculture. In Brazil, understanding soil reaction is crucial for plantation crops like coffee, sugarcane, and soybeans, which are sensitive to pH levels. Liming (calagem) is a common practice to correct acidic soils in both countries. The term is highly technical and used primarily in agronomic, environmental, and scientific contexts.
