What are the advantages and disadvantages of compound fertilizer?

The main advantages and disadvantages of compound fertilizer are as follows:

(1) Compound fertilizer contains multiple nutrients, which can realize the coordinated application of nitrogen, phosphorus and potassium, and has high fertilizer efficiency and utilization rate. The compound fertilizer can also be made into a series of special fertilizers according to the nutrient status of different types of soil and the characteristics of crop fertilizer demand, which has strong pertinence, remarkable fertilizer efficiency and high fertilizer utilization rate and economic benefit.

(2) The compound fertilizer has certain compressive strength and granularity, good physical properties and convenient application.

(3) Compound fertilizer contains many nutrients, and reasonable application can promote the balance of soil nutrients. Farmers are used to applying more elemental fertilizers, especially a large amount of nitrogen fertilizers, and rarely applying potassium fertilizers. The application of organic fertilizers is getting less and less, which easily leads to the imbalance of soil nutrients.

Disadvantages: First, the nutrients contained in it are applied at the same time, and some nutrients may not match the maximum fertilizer demand period of crops, which is easy to be lost and difficult to meet the special needs of crops for nutrients in a certain period. Second, it is difficult for compound fertilizer with fixed nutrient ratio to meet the requirements of various soils and crops at the same time.
