On the extreme effect of phosphorus
The method of fertilizing soil is related to the application of phosphorus, which is the key. Phosphorus, which is conducive to the vitality of crops, helps non-light, and can promote dense root systems. Flowers and fruits mature early, and the fruit is full. However, the beauty of using phosphorus is about moderation, and more is better.

In the past, farmers did not notice, and often applied phosphorus excessively, thinking that the more it was, the more it would produce. In fact, excessive phosphorus accumulated in the soil, causing various disadvantages. First, the soil was compacted, the ability of ventilation and water was gradually weakened, and the root system was trapped. Although it was called fertile soil, it was not nourishing. Second, the imbalance of nutrients with other species, such as iron, zinc, calcium, etc., makes it difficult for crops to ingest, resulting in various diseases, yellow leaves and withered branches, and weak fruits.

Therefore, the extreme effect of phosphorus should be understood. According to the fat and thinness of the ground, observe the needs of crops, and apply it accurately. At the beginning, it is necessary to carefully measure the soil, know the stock of phosphorus, and then supply it according to the stage of crop growth. At the beginning of germination, if the roots want to grow rapidly, it is advisable to increase phosphorus slightly, so as to promote the growth of roots, and to penetrate the ground deeply and steadily. During the flowering and fruiting periods, phosphorus can help the flowers to flourish, the fruits to breed, and replenish them in a timely manner.

Furthermore, the method of applying phosphorus is also exquisite. Or base application, which is integrated with the soil, is the long-term nourishment of crops; or topdressing, which is precisely replenished according to the needs of the time. And it can be applied with organic fertilizer to adjust the properties of the soil and increase the effect of phosphorus. In this way, the maximum effect can be achieved, and the yield is prosperous and the land is not declining. The benefit of farmers and the nourishment of the land can be achieved.
