What Is the Best Time to Apply Foliar Fertilizer to Corn?
Corn foliar fertilizer can coordinate and promote growth and increase corn yield per unit area. So when is the best time to apply corn foliar fertilizer? Let's take a look together.
1. When is the best time to apply corn foliar fertilizer?
Early stage: the best period is when the corn seedlings have grown 6 or 7 leaves.
Late stage: applying it one week (7 days) before the corn ears form has the same effect.
Applying foliar fertilizer twice is enough. You can choose carbon-supplement foliar fertilizer. The effective period of foliar fertilizer is 3 weeks, about 20 days. The interval between the first and second application should preferably be 10-15 days, and it is best to apply the product before 10 a.m. when the weather is not hot, or after 4 p.m.
2. What kind of corn is suitable for foliar fertilizer?
If the corn is growing weakly, you can apply fertilizer once first. The fertilizer needs to be urea that promotes growth, applying 50 jin per mu. Later, when about 10 corn leaves have basically all unfolded, you can also apply another 50 jin as a top dressing.
Note: if the corn has other pests or diseases, before applying foliar fertilizer, you must carefully consult about the various conditions and restrictions for spraying.
During the growth of corn, there are several periods when foliar fertilizer cannot be used: the flowering period, the seedling stage, and the afternoon of a day with high temperatures and exposed sunlight.
Generally speaking, to increase corn yield, most farmers who grow corn at home adopt the method of applying foliar fertilizer. In this way, reaching a yield of 1600 per mu is not a big problem. Compared with corn, the yield can increase by 20%. Calculated by an area of 10 mu, one crop can increase yield by about 3000 jin.
Corn foliar fertilizer is very beneficial to the growth of corn. When foliar fertilizer is sprayed properly, it will reduce pests and diseases in corn and allow normal growth and ear formation. I hope everyone can effectively use foliar fertilizer to make corn more productive.
