Scientific Fertilization for High-Yield Sweet Corn — Exclusive Biofert Solution

To grow sweet corn with plump kernels and superior sweetness, scientific fertilization is the core, and soil testing is the primary condition for customizing a fertilization plan. Send soil samples to Biofert, where agronomists will tailor fertilization recommendations to precisely match the nutrient requirements of sweet corn throughout its entire growth cycle, avoid inputting nutrients already sufficient in the soil, and save planting costs from the source.

Targeted Fertilization, Precision Application

• Potassium Supplementation: For potassium-deficient soil, apply a sufficient amount of potassium fertilizer before planting and till the soil. Biofert offers pure potassium salt, potassium sulfate, and high-potassium compound fertilizers. For magnesium-deficient soil, langbeinite mineral fertilizer (0-0-22+22S+11Mg) is available to supplement both potassium and magnesium simultaneously.
• Phosphorus Supplementation: Apply phosphorus precisely using the "2×2" placement method during sowing, placing the fertilizer 2 inches below the seeds. Biofert's high-phosphorus starter fertilizers (9-40-4/14-28-6/11-18-14) all contain boron, and combined application with nitrogen, potassium, magnesium, and sulfur is more efficient, preventing boron absorption inhibition.
• Nitrogen Supplementation: For sandy, low-nitrogen soil, apply nitrogen fertilizer in advance (can be mixed with potassium fertilizer). If soil fertility is unknown, conduct a Biofert Nitrate Rapid Test to accurately determine the side-dressing nitrogen amount before the corn reaches knee height, avoiding excessive vegetative growth or yield reduction. A full range of nitrogen fertilizers is available for selection as needed.
• Trace Element Supplementation: For nutrient deficiencies during the growing period, foliar spraying is recommended. Biofert provides sulfate-type and chelated-type micronutrient fertilizers (available in powder/liquid forms) to quickly alleviate yellowing and slow growth issues.

Synergists for Doubled Fertilizer Efficiency

When fertilizing sweet corn at all growth stages, combine with Biofert's patented agricultural synergists to significantly improve fertilizer absorption rate, saving labor and enhancing efficiency:

• Zhanshensan with Drench/Broadcast Fertilizers: Integrates three effects (spreading, penetrating, dispersing), fixes nutrients around the root system, reduces nutrient loss, and improves absorption efficiency;
• Zhanshensan with Foliar Micronutrient Sprays: Enables fertilizer solution to adhere evenly to leaves and quickly penetrate the cuticle, relieving nutrient deficiency symptoms faster;
• Shikuole for Fertilization and Pest Control: Kills mites and their eggs, improves pesticide efficacy, and enhances the effect of both fertilizer and pesticide, achieving dual benefits with one application.

Based on professional soil testing, Biofert offers a full range of environmentally friendly fertilizers plus high-efficiency synergists to create a one-stop "Testing - Fertilization - Synergizing" solution for sweet corn, providing precise nutrient supply to help grow high-yield, high-quality sweet corn.
