Some farmers believe that the more phosphorus fertilizer is applied to crops, the higher the yield. Therefore, in recent years, the amount of phosphate fertilizer applied in farming has increased more than a year, and some even increased exponentially. As everyone knows, this not only increases the cost of farming, but also does not necessarily increase production.
Relevant research data show that long-term large-scale application of phosphate fertilizer will deteriorate the physical and chemical properties of the soil (alkaline acidification or alkalinity), and the trace elements will lose balance, which will affect their normal growth and development, and even reduce production.
To this end, the author advises the majority of farmers, scientific farming should be based on the soil fertility, soil conditions, rational application of nitrogen, phosphorus, potassium fertilizer and trace element fertilizer, preferably heap and wide application of farmyard manure to improve crop yield and quality, In order to change the situation that "the rice is not fragrant, the dish is not fresh, the fruit is tasteless".
