Standing at the edge of her field, Yang Yan finally let out a sigh of relief after months of anxiety. This year, the corn crop in Central Liaoning endured a brutal sequence of waterlogging followed by scorching heat. Weeks of relentless rain and overcast skies left fields waterlogged, with drainage systems overwhelmed and large areas of corn submerged for extended periods, causing root oxygen deprivation, blackening, and yellowing leaves. Just as conditions seemed to stabilize, August brought a sudden shift—an entire month of high temperatures and drought that dried out the soil completely, compounding the stress on already damaged plants. Many local farmers shook their heads in despair, predicting, "This year's corn will be lucky to yield even 60 to 70 percent of normal."

Yet amidst this grim outlook, Yang Yan's 300-plus acres of corn stood tall and vibrant, with lush green leaves and uniform, fully developed ears. Word spread quickly, and over 80 growers flocked to her fields to witness the phenomenon firsthand—how, despite enduring the same flood-then-drought cycle, her corn remained so remarkably resilient.

Side-by-Side Comparison: One Field Struggles, Another Thrives

The field day event deliberately selected two adjacent plots with identical conditions: the same soil, the same corn variety, and the same management practices. The only variable was the fertilization approach—one plot used the "Yangfeng Dual-Control" fertilizer, while the other received a standard local fertilizer. Walking into the control plot, the scene was disheartening: corn plants showed widespread yellowing at the base and premature senescence, with lower leaves withered and overall growth stunted. Inspecting the ears revealed numerous empty stalks and poorly developed cobs, with many exhibiting misshapen forms such as dumbbell-like, grenade-like, or star-shaped ears, severe tip dieback, and sparse kernels. One farmer observed with a shake of his head, "These fields were flooded early on and then hit by drought. Without proper nutrition, the ears have turned into deformed, undersized messes."

Turning to the "Yangfeng Dual-Control" demonstration plot, the contrast was striking. Even as harvest approached, the entire field remained a deep green, free from premature aging, nutrient deficiency, or yellowing. Randomly selected ears were uniform in size, with plump, tightly packed kernels and virtually no tip dieback or malformed cobs. Onlookers eagerly pulled out their phones to capture the difference: "These ears are beautiful—compared to the control plot, it's like night and day."

Using 20 Jin Less Fertilizer Per Mu, Yet Earning 300 Yuan More

Yang Yan stepped forward to share her cost-benefit analysis with the crowd: "Across my 300-plus acres, I used 'Yangfeng Dual-Control' exclusively, applying 120 jin per mu in a single pass. Previously, with conventional compound fertilizer, I needed 130 to 140 jin per mu. I'm using less fertilizer, saving on labor, and getting better results." The yield assessment brought the event to its climax. Staff randomly collected ears, shelled them, and weighed the kernels: 15 ears from the demonstration plot produced 4.190 kilograms of wet grain, compared to 3.415 kilograms from the control plot. This translated to a calculated yield of 977.67 kilograms per mu for the demonstration plot versus 796.83 kilograms for the control—an increase of 180.84 kilograms per mu. At the current market price of 1.7 yuan per kilogram, that equates to an additional 307 yuan per mu in revenue.

"With over 300 acres, that's more than 90,000 yuan extra," Yang Yan said with a smile. "I originally chose 'Yangfeng Dual-Control' because of its long-lasting efficacy and sustained nutrient release. This year's extreme weather really put it to the test—it doesn't lose nutrients during flooding, doesn't show premature aging during drought, and holds up when it matters most."

Quality Fertilizer Stands Up to Extreme Weather, Results Speak for Themselves in the Field

The field day gave more than 80 growers a firsthand look at how "Yangfeng Dual-Control" performed under extreme conditions. As the event wrapped up, many lingered to question Yang Yan and the agronomists from Xinyangfeng about application details, already planning to switch to the product next season. The flood-drought sequence of 2026 served as a true test for Central Liaoning's corn crop, and "Yangfeng Dual-Control" delivered a straightforward answer: no excessive growth in the early stages, no nutrient deficiency later on, stable yields even in disaster years, and even higher output in good years. Quality fertilizer withstands extreme conditions, and real results are proven directly in the field.
