Ten Ways to Increase Corn Yield by Soaking
The use of non-pesticide seed treatments for corn soaking can significantly enhance germination, promote early emergence, reduce disease incidence, and improve overall plant growth, ultimately increasing yield by 10% to 15%. This method is not only easy to implement but also cost-effective, making it a highly beneficial practice for farmers. Below are ten effective soaking techniques that you can try:
**Borax Solution:** Mix 5 grams of borax in warm water, then add 5 liters of water. Soak the corn seeds in this solution for 12 hours before planting.
**Potassium Permanganate:** Dissolve 5 grams of potassium permanganate in 5 liters of water. Soak the seeds for 25 hours, then drain and sow.
**Tung Oil Treatment:** Mix 500 grams of tung oil with 6 kilograms of corn seeds. This method helps improve drought resistance and enhances seed viability.
**Urea Soaking:** Prepare a solution of 100 grams of urea in 10 liters of water. Soak the seeds for 10–12 hours, then drain and plant.
**Superphosphate Treatment:** Soak the seeds in clean water for 2 hours. Then mix 20 grams of superphosphate per kilogram of seeds before sowing.
**Potassium Dihydrogen Phosphate (KH₂PO₄):** Prepare a solution of KH₂PO₄ diluted 300–500 times. Soak the seeds in 6 liters of the solution for 10 hours before planting.
**Human Urine Soaking:** Mix human urine with clean water and soak the corn seeds for 12 hours. This natural treatment can boost plant growth and health.
**Zinc Sulfate Solution:** Dissolve 50 grams of zinc sulfate in enough water to cover 10 kilograms of seeds. Let the mixture cool, then sow. This also helps prevent white mold disease.
**Vinegar Soak:** Mix 100 grams of vinegar with 10 liters of water. Soak the seeds for 24 hours, then drain and dry before planting. This helps protect against corn smut.
**Spraying Po (Shi Bao):** Mix 5 ml of Shi Bao with 50 liters of water. Soak the seeds for 10 hours, then dry and plant. This is an effective organic treatment for improving seed quality.
These methods are all eco-friendly, safe, and have been used successfully in various regions. By using these natural solutions, farmers can reduce chemical dependency while still achieving better crop performance and higher yields. Whether you're a small-scale grower or part of a larger agricultural operation, trying out one or more of these soaking techniques can be a smart and sustainable choice.
