Of the many factors that contribute to the high yield of crops, water and fertilizer are two of the most important factors. As the saying goes, "there is no income in the water, and less income in the income." This shows that timely irrigation can ensure that crop water demand is a limiting factor for crop growth. Similarly, whether or not it can reasonably fertilize crops in time to meet nutrient needs is the key to determining crop yields. It can be seen how important the two measures of fertilization and irrigation are in agricultural production.
There are two general situations: one case is that when the funds are sufficient, it can increase the amount of fertilizer to meet the needs of the crop for nutrient elements in a timely manner, implement balanced fertilization, and strive to achieve the comprehensive goal of high yield, high quality, and high efficiency. Another situation is that when there is insufficient funds to buy enough fertilizer, as long as the combination of fertilization and other stimulation measures is combined, the limited fertilizer can also maximize the increase in production efficiency. For example, the combination of water and fertilizers, or the combination of nitrogen, phosphorus and potassium. In doing so, a better harvest can be obtained even if the fertilizer is applied less.
In the process of crop yielding, there is a contribution to irrigation, called the effect of water, and also a contribution to fertilization, called the effect of fertilizer, but many farmers do not know that there are two effects of water and fertilizer in the process of crop yielding. In addition, there is a third effect produced by the combination of water and fertilizer, known as the interaction effect. It can be seen that the effect of combined irrigation and fertilization on production is much greater than the sum of the effects of single irrigation or fertilization. Therefore, the current promotion of balanced fertilization techniques and the promotion of fertilization in combination with agricultural technological measures are undoubtedly very important for obtaining high crop yields.
Expert Tips:
1. Within a certain range, fertilizing materials can increase crop yields, but the further increase in production also requires the cooperation of other measures.
2. The combination of fertilization and irrigation can enable the limited fertilizer to maximize its production increase, which is due to the combination of water and fertilizer.
