What fertilizer is best to apply during corn filling period?

Potassium dihydrogen phosphate can be applied to the leaves during the corn filling period.

During the corn filling period, if nutrients are insufficient, 0.5 kg of urea and 0.1 kg of potassium dihydrogen phosphate per mu can be used, and 50 to 60 kg of water can be sprayed on the leaves. If there is a lack of trace elements, the corresponding micro-fertilizer can be sprayed at the specified concentration. Spray once every 7 to 10 days. The effect is better on sunny days. If it is sunny, it should be sprayed after 3 p.m. In rainy weather, spray should be applied after the leaves are slightly dry after rain. Note that the fertilizer solution should be applied as needed.

When the land is deficient in zinc, 0.1-0.2% zinc sulfate can be applied, and an appropriate amount of lime liquid can be added, mixed with water and sprayed. The suitable growth temperature for corn during the filling period is 22-24°C. Aphids need to be controlled in the seedling stage of corn, and 2000 times of 90% trichlorfon wettable powder can be used for control.

What fertilizer has the highest yield on corn?

Use Wandibao potassium dihydrogen phosphate type compound fertilizer, which is fully water-soluble and has no residue. It has the functions of loosening soil and retaining water. It can be quickly absorbed by crops, has long fertilizer effect, and significantly increases production. It is more powerful than ordinary fertilizers and has sufficient stamina. In the early stage, the seedlings are strong but not too long. In the later stage, they do not lose fertilizer and do not suffer premature aging. They have strong resistance to repeated cropping, full grains, and stable and high yields.

Using nitrogen fertilizer for corn can achieve high yield. Corn has the greatest demand for nitrogen fertilizer during the entire growth cycle and less demand for potassium and phosphorus fertilizer. Seed fertilizer must be applied when corn is sown, which will facilitate seed emergence and provide the nutrients needed by the seedlings. During the corn seedling period, quick-acting fertilizer must be applied as seed fertilizer.
