As an important corn producer and exporter in the world, corn production in Brazil is deeply affected by climate. Among them, El Nino and La Nina are the main factors causing abnormal climate in Brazil, which have a significant impact on corn planting. Some market intelligence officers said that the return of La Nina in 2025, even if its intensity is weak, may bring challenges to soybean and corn harvests, affecting their productivity and international trade markets.
The impact of El Nino and La Nina on corn planting in Brazil
- El Nino: El Nino usually leads to increased rainfall and higher temperatures in southern Brazil, while the north and northeast are more dry. For corn planting, excessive rainfall in the south may cause floods, affect corn planting, growth and harvesting, and increase the risk of pests and diseases. Drought in the north and northeast will inhibit corn growth and lead to reduced production.
- La Nina: La Nina usually leads to less rainfall and lower temperatures in southern Brazil, while northern and northeastern regions are more humid. For corn planting, drought in the south will affect the growth and development of corn, while excessive rainfall in the north and northeastern regions may lead to floods and affect corn yield and quality.
Application of biostimulants in coping with climate anomalies
Biostimulants are a class of natural or synthetic substances that can promote plant growth, improve stress resistance and improve quality. Different biostimulants can play different roles in coping with climate anomalies.
- Improve drought resistance: Biostimulants such as humic acid, seaweed extract and amino acid can promote plant root development, improve water use efficiency, enhance drought resistance, and help corn cope with drought stress.
- Relieve high temperature stress: Biostimulants such as γ-PGA, glycine betaine and proline can regulate the osmotic pressure in plants, protect cell membrane structure, and alleviate the damage caused by high temperature to corn.
- Improve disease resistance: There are also some biostimulants such as chitosan oligosaccharide, which can induce plants to produce disease-resistant substances, enhance resistance to diseases and pests, and reduce the occurrence of diseases and pests caused by climate fluctuations.
The impact of El Nino and La Nina on corn planting in Brazil cannot be ignored. Through the rational application of biostimulants, the stress resistance of corn can be effectively improved, the negative impact of climate anomalies can be reduced, and stable and high yields of corn can be ensured. In terms of drought resistance and water conservation, Dora is committed to studying different biostimulants and advocating sustainable products to better alleviate this problem. We especially recommend Dora KelpReal, Glycine Betaine, γ-PGA, Chitosan Oligosaccharide, etc. In the future, with the continuous deepening of biostimulant research and the continuous improvement of application technology, it will play a more important role in responding to climate change and promoting sustainable agricultural development.
