What is the difference between compound fertilizer and general fertilizer?
NPK compound fertilizer is a fertilizer with more than two kinds of nutrients. It is widely used in agriculture, so the sales volume is also very good. The NPK fertilizer production mainly includes granulation such as disc granulation, drum granulation, spray granulation, ammonia granulation and the like process.
1. Compound fertilizer saves cost and saves part of the cost: the compound fertilizer has less auxiliary components, the active ingredient content is higher than that of the single fertilizer, the fertilizer amount of the same nutrient quantity becomes smaller, the packaging and transportation cost are low, and it is convenient to use.
2. There are many types of compound fertilizers, which are beneficial to the selection and application of differentiation. The main advantage of compound fertilizers is that they can be selected and applied according to the characteristics of soil nutrients and the nutritional characteristics of crops to avoid the waste of certain nutrients and greatly improve the fertilizer. Increase production results.
3. The compound fertilizer has few sub-components and has little adverse effect on the soil: the nutrients contained in the compound fertilizer are mostly necessary for crops, which can avoid the waste of certain material resources and avoid the adverse effects of certain accessory components on the soil.
4, compound fertilizer nutrient is relatively comprehensive, and high content: contains two or more nutrients, can provide a variety of nutrients needed for crops in a relatively balanced and long time, and improve the effect of fertilization.
5. The compound fertilizer has good physical properties and is easy to apply: the size of the compound fertilizer is generally uniform and the hygroscopicity is small for storage and application, and is suitable for mechanized application.
Precautions for applying compound fertilizer
Compound fertilizer has the advantages of high nutrient content, less auxiliary components and good physical properties. It plays an important role in balancing fertilization, improving fertilizer utilization rate and promoting high yield and stable yield of crops. However, it also has some shortcomings, such as its nutrient ratio is always fixed, and the types, quantities and proportions of nutrients required for different soils and different crops are diverse. Therefore, it is best to conduct soil testing before application to understand the texture and nutritional status of the field soil.
