Compound fertilizer containing nitrogen, phosphorus, potassium fertilizer application without covering the soil nutrients will be volatilized?

If a compound fertilizer containing nitrogen, phosphorus and potassium is applied without covering the soil, the nutrients may be volatilized.

The nitrogen, phosphorus and potassium in compound fertilizers exist in chemical form, and when fertilizers are applied without mulching, the chemicals in the fertilizers will volatilize into the air, resulting in nutrient loss. At the same time, if the soil is not covered after fertilizer application, the fertilizer will also be susceptible to rainfall and erosion, further leading to nutrient loss and waste.

Therefore, you should pay attention to mulching when applying fertilizers to protect the nutrients in the fertilizers from being volatilized and lost, so as to better provide nutrients to the plants.
