Basic fertilizers and premium fertilizers: understanding the application and difference

In the process of agricultural production, the selection and use of fertilizers are crucial to the growth and yield of crops. Basic fertilizers and premium fertilizers each have their own characteristics and advantages. According to different needs, they are applied to different planting stages and crop types. This article will discuss in detail the differences, characteristics and applications of basic fertilizers and premium fertilizers in agricultural production to help farmers apply fertilizers scientifically and achieve the best agricultural benefits.

Characteristics and application of basic fertilizer

Basic fertilizer, also known as base fertilizer, is a type of fertilizer applied before planting or when sowing crops. It is mainly used to supplement the basic nutrients in the soil, such as nitrogen, phosphorus, potassium, etc. These fertilizers are usually applied to the soil surface, which can effectively improve the soil structure and provide a continuous supply of nutrients for plants.

The main characteristics of basic fertilizers

• Comprehensively replenish soil nutrients and improve the physical structure and chemical properties of the soil.
• Provides necessary nutrients for the basic growth of plants and promotes root development.
• The application method is simple and suitable for large-scale agricultural planting.

Common types of basic fertilizers

The following are several common basic fertilizers and their characteristics:

• Compound fertilizer: contains two or more nutrients and is suitable for a variety of soils and crops.
• Organic fertilizers: such as compost and manure, mainly provide organic matter and trace elements, which can improve soil fertility.
• Mineral fertilizers: such as phosphate rock powder and potash rock powder, mainly supplement specific mineral elements.

Characteristics and application of high-quality fertilizers

High-quality fertilizers usually refer to fertilizers containing high-efficiency ingredients or specific nutrients, and are mainly used to supplement the nutrition of crops during their growth period. This type of fertilizer focuses on the efficient absorption and utilization of nutrients, and can significantly improve the quality and yield of crops.

Main characteristics of high-quality fertilizers

• Contains highly effective ingredients that can be quickly absorbed and utilized by plants.
• Provide specific nutrients according to the growth needs of different crops.
• The application amount is small, the effect is remarkable, and it is suitable for refined management.

Common types of high-quality fertilizers

The following are several common high-quality fertilizers and their characteristics:

• Water-soluble fertilizer: After being dissolved in water, it can be directly sprayed or drip-irrigated to quickly provide nutrients and is suitable for greenhouse cultivation.
• Slow-release fertilizer: By controlling the rate of nutrient release, it continuously provides nutrients to crops and reduces the number of fertilization times.
• Trace element fertilizers: such as iron fertilizer and zinc fertilizer, which are specifically used to supplement trace elements and prevent and treat nutrient deficiencies.

Guidance on scientific fertilization

In actual production, the rational selection and matching of basic fertilizers and high-quality fertilizers is an important means to achieve efficient agriculture. Here are some suggestions for scientific fertilization:

• Determine the type and amount of fertilizer to be applied based on the soil test results to avoid blind fertilization.
• Based on the growth stage and fertilizer requirements of crops, reasonably arrange the application time of basic fertilizers and high-quality fertilizers.
• Pay attention to the growth of crops and adjust the fertilization plan in time to ensure a balanced nutrient supply.

Through scientific fertilization, we can not only improve the yield and quality of crops, but also effectively protect soil resources and achieve sustainable development of agriculture.
