Why is one-time fertilization recommended for corn planting? Is it different from traditional fertilization?

Fertilizer is more important in the process of corn growth. In our hometown of Henan, corn is planted with base fertilizer and topdressing, which can fully ensure the nutritional needs of corn at different stages of growth. At present, some lazy growers buy one-time fertilization without topdressing. Will that affect the corn harvest? Is it really possible to increase production? As a corn grower, let me share my opinion with you.

Reasons for the rise of one-time fertilization

Since ancient times, it has been thought that the growth stage of corn can not be separated from the support of fertilizer. The normal growth cycle of corn will not exceed 4 months, and energy care during this period will be easier than other crops. In addition, some farmers are too lazy to take care of corn and want convenience and high yield. As a result, some agricultural technicians began to study the improvement of fertilizer and soil, and repeatedly tried the fertilizer formula suitable for corn growth. Finally, a kind of fertilizer favored by corn growers in recent years-special compound fertilizer for hulling and slow release has appeared. This kind of slow-release special fertilizer simplifies the times of topdressing to a certain extent, and is also favored by some growers because of the gimmicks frequently publicized by manufacturers.

Does one-time fertilization increase production?

As a corn grower for 20 years, let me first talk about my neighbor Lao Zhang's experience in growing corn. Lao Zhang's family has a lot of business, mainly raising cattle and chickens and ducks. He also opened a wholesale vegetable shop in the town, and he was as busy as a top all day. Lao Zhang doesn't grow much corn at home, only about 2 mu, mainly for his own use and livestock in breeding factories. The artillery bombardment of special slow-release compound fertilizer is very popular with Lao Zhang, because it is a one-time fertilization, which reduces manpower and fertilization amount, regardless of fertilization frequency, so that he has more time to be busy with other things. However, judging from Lao Zhang's corn harvest in recent years, the yield is less than that of applying conventional base fertilizer in batches, and the corn harvest will not increase.

A special slow-release compound fertilizer was shelled. It will release different fertilizer efficiency according to different stages of corn growth, but the growth of corn is not only affected by fertilizer, but also related to corn varieties, climate, intertillage weeding, tasseling stage, pollination stage, pest control and so on, so it is very difficult for this fertilizer to replace the traditional method of base fertilizer+topdressing. The key period of increasing yield is the application of base fertilizer and the big horn stage of corn. In these periods, we are all using compound fertilizer, not just ordinary ternary compound fertilizer.

If you want to get high yield of corn, you must not apply fertilizer at one time. What you need is to apply different amounts of fertilizers and corresponding types of fertilizers at each stage, plus the right time and place to get high yield. In the process of maize growth, it has experienced the test of high temperature and drought, and the utility of fertilizer will also change accordingly. We should pay close attention to various conditions of maize growth.
