Corn Fill – Corn Late Stage Specialty Fertilizer

Corn in the late growth stage is highly sensitive. A small problem at this stage can affect kernel set, grain filling, and final yield. During silking, pollination, and grain development, the plant needs stable nutrition, strong photosynthetic activity, and better stress tolerance.

Corn Late Stage Specialty Fertilizer is designed for this critical stage. It combines free amino acids, magnesium, zinc, water-soluble boron, and glutathione to support corn from tasseling through grain filling. The goal is simple: help the crop move nutrients efficiently, keep leaves active longer, and support fuller ears with better kernel weight.

Technical Specification:

Free Amino Acids ≥100g/L, Ca+Mg ≥30g/L

Why Corn Needs a Late Stage Specialty Fertilizer

Many growers focus on early growth, but corn yield is often decided later. Once the crop enters the reproductive stage, it needs:

• steady energy supply for grain filling
• active leaves that can continue photosynthesis
• better pollen viability and fertilization quality
• support against heat, drought, and other late-season stress
• improved nutrient transport into the ear and kernels

When these needs are not met, the result can be poor tip fill, empty kernels, weak grain weight, and uneven maturation. A targeted late stage fertilizer helps reduce that risk.

Benefits:

Specifically developed for mid-to-late corn growth needs. Uses highly active L-α free amino acids as the core, scientifically compounded with chelated Magnesium, Zinc, and Boron, and specially added Glutathione, precisely tailored for mid-to-late corn requirements. Highly active L-α free amino acids promote corn ear differentiation and tassel development, support uniform tasseling, and improve kernel set. From silking to grain filling stages, it activates physiological activity, synergizing with chelated Magnesium to maintain chlorophyll stability and enhance photosynthetic efficiency, providing continuous energy for grain filling. Chelated Zinc activates starch synthase activity, working with Boron to ensure pollen vitality and fertilization quality, reducing tip blanking and empty kernels, promoting efficient protein and starch accumulation for plumper grains and higher thousand-kernel weight. Specially added Glutathione, with its sulfhydryl groups (-SH), precisely scavenges reactive oxygen species under high temperature and drought stress, reducing cell membrane damage. Simultaneously regulates endogenous hormones, promoting nutrient translocation to kernels during filling, ensuring corn completes grain filling and maturation stably, contributing to both yield and quality improvement.

Applicable Crops:

corn at late stage

Application Instructions

Foliar Spray

Dilute 800–1000 times and apply every 7–10 days for 2–3 consecutive applications.

Fertigation / Drip Irrigation

Apply 15–30 L per hectare.

For best results, apply under suitable weather conditions and follow local agronomic recommendations based on crop condition, soil fertility, and growth stage.

Product Advantages Compared with General Fertilizer

A general fertilizer can keep the crop growing, but a stage-specific formula is better when the plant is already in the yield-building phase.

Cautions

• Avoid mixing with strongly acidic or alkaline fertilizers and pesticides.
• If tank mixing is needed, conduct a small compatibility test first.
• If rain occurs within 4 hours after spraying, reapplication at a reduced rate may be necessary.

Storage

• Store and transport in the original container.
• Keep sealed in a cool, dry place.
• Store separately from food, drink, and feed.
• Keep out of reach of children and livestock.

Production date and lot number: see bottle cap.
Shelf life: 36 months.

FAQ

What is Corn Late Stage Specialty Fertilizer used for?

It is used to support corn during tasseling, silking, pollination, and grain filling. It helps improve nutrient movement, kernel set, and late-stage crop vitality.

Why is magnesium important at the corn filling stage?

Magnesium supports chlorophyll stability and photosynthesis. Healthy leaves can continue producing energy for the kernels during grain filling.

How do zinc and boron help corn?

Zinc supports enzyme activity and metabolic processes, while boron supports pollen vitality and fertilization quality. Together, they help improve kernel formation.

Can this product be used with other fertilizers or pesticides?

It may be possible, but compatibility should be tested first, especially with strongly acidic or alkaline products.

What is the application rate for foliar spraying?

The recommended dilution is 800–1000 times, applied every 7–10 days for 2–3 applications.
