Whether to use urea or compound fertilizer for fertilizing leeks needs
First of all, urea is a nitrogen fertilizer whose main function is to promote the growth of stems and leaves of leeks and increase yield. If the growth of leeks is weak and nitrogen needs to be replenished quickly, you can choose to apply urea. However, excessive application of urea will lead to excess nitrogen in the soil, which will not only affect the absorption of other elements by leeks, but also cause problems such as seedling burning and soil compaction.
Compound fertilizer is a fertilizer containing multiple elements such as nitrogen, phosphorus, potassium, etc., which can meet the needs of leeks for multiple nutrients and promote the healthy growth of the plant. If leeks are growing well and need to supplement a variety of nutrients, you can choose to apply compound fertilizer. However, the proportion of nutrients in compound fertilizer is fixed. If the proportion is inappropriate, the fertilization effect will be affected.
Therefore, when choosing fertilizer, it is necessary to comprehensively consider factors such as the growth status of leeks and soil conditions. If there is insufficient nitrogen in the soil, you can choose to apply urea; if there are insufficient nutrients in the soil, you can choose to apply compound fertilizer. At the same time, attention needs to be paid to controlling the amount and frequency of fertilization to avoid excessive fertilization and over-reliance on a single fertilizer.
