What fertilizer is the best for planting leeks?

Soybean fertilizer, plant ash, cake fertilizer, chicken manure, ammonium sulfate and other fertilizers are most suitable for planting leeks.

1, soybean fertilizer

Put the soybeans in a plastic bucket, then cover them with appropriate amount of water, leave them for about a week, and then bury them in the ground as a base fertilizer, which can be applied at a rate of 200-300 kg per mu.

2. plant ash

Plant ash is a typical potash fertilizer, especially suitable for potash-loving crops, such as beans and vegetables. It was recorded in the late Qing Dynasty that plant ash soil fertilizer was used to grow broad beans and peas, which was useless and fat. In a few words, plant ash's status could be seen.

3, cake fertilizer

Cake fertilizer is a kind of high-quality organic fertilizer, with the highest content of nitrogen, phosphorus and some potassium, but the nutrients in cake fertilizer can only be used by leeks after being decomposed by microorganisms in the soil. Therefore, when applying cake fertilizer, it should be fully decomposed and used correctly, otherwise it may not be effective for a whole year.

4. Chicken manure

Chicken manure is rich in nutrients, including nitrogen, phosphorus and potassium. The proportions of nitrogen, phosphorus and potassium in chicken manure are 1.6%, 1.54% and 0.86% respectively, and it also contains many trace elements, far more than pig manure. Therefore, the application of chicken manure is beneficial to the root growth, rapid plant growth and quality improvement of Chinese chives.

5. Ammonium sulfate

Compared with the above-mentioned organic fertilizer, ammonium sulfate has faster fertilizer efficiency and more sufficient fertilizer efficiency. The main component of ammonium sulfate is nitrogen, which is the main component of chlorophyll and is closely related to photosynthesis. Under the condition of nitrogen deficiency, leek plants are short, with few tillers and yellow leaves. Using ammonium nitrate or urea in leek planting can increase the yield of leek and avoid fertilizer waste and soil pollution.
