What is the difference between farmyard manure and chemical fertilizer? There are many benefits to applying them in a reasonable combination

Fertilization refers to agricultural technical measures of applying fertilizer to the soil or spraying it on plants to provide the nutrients plants need and to maintain and improve soil fertility.So what are the benefits of applying farmyard manure and chemical fertilizer in a reasonable combination? What are their differences?

What are the benefits of applying farmyard manure and chemical fertilizer in a reasonable combination?

Mixing farmyard manure and chemical fertilizer together for application can bring quite a few benefits. Different types of crops have different fertilizer requirements and patterns, and there are large differences in the proportions of various nutrients they need. Although farmyard manure contains comprehensive nutrients and comes from a relatively wide range of sources, its content is relatively low, making it difficult to reasonably supply and regulate the various nutrients essential for crops. At the same time, because its fertilizer effect is slow, it is not conducive to direct absorption by crops, and it is even more difficult to evenly meet nutrient needs at different growth stages. Although chemical fertilizer has relatively single nutrients, its fertilizer effect is fast. Applying farmyard manure and chemical fertilizer in a reasonable combination allows nutrients to supplement each other, with slow and fast fertilizer effects complementing each other, which is conducive to a balanced supply of nutrients and achieves good fertilizer efficiency.

1. It can comprehensively supply the nutrients needed for crop growth. Chemical fertilizer is characterized by high nutrient content, fast fertilizer effect and short duration, and relatively single nutrients; farmyard organic fertilizer is mostly a complete fertilizer, but its nutrient content is low, and its fertilizer effect is slow and long-lasting. Therefore, mixing chemical fertilizer with farmyard organic fertilizer for application can make up for each other's shortcomings, so that the nutrient elements in the fertilizer are fully absorbed.

2. It can reduce nutrient fixation and improve fertilizer efficiency. After chemical fertilizer is applied to the soil, some nutrients will be absorbed or fixed by the soil, thereby reducing the availability of nutrients. If it is mixed with farmyard manure, the contact surface between chemical fertilizer and soil can be reduced, thereby reducing the chance of being fixed by the soil.

3. It can retain and store nutrients, reduce loss, and improve the conditions for crops to absorb nutrients. Chemical fertilizer has high solubility, and after application it creates a relatively high osmotic pressure in the soil, affecting the absorption of nutrients and water by crops, which increases the chance of nutrient loss. If it is mixed with farmyard manure for application, this drawback can be avoided.

4. It can regulate soil acidity and alkalinity and improve soil structure. Farmyard manure is the raw material for the life of microorganisms, and chemical fertilizer supplies the inorganic nutrients for the growth and development of microorganisms. Mixing the two can promote the activity of microorganisms, thereby promoting the decomposition of organic fertilizer.

What are the differences between farmyard manure and chemical fertilizer?

1. Farmyard manure contains various nutrient elements needed by crops and abundant organic matter. It is a complete fertilizer, also called organic fertilizer. This kind of fertilizer has a wide range of sources, long-lasting residual effect, strong fertilizer retention capacity, and the effect of building soil fertility and improving soil, and it is low in cost, with no adverse effects on soil and crops. The disadvantages are low nutrient content and slow fertilizer effect.

2. Chemical fertilizer is the abbreviation of chemical fertilizer, with raw materials including ore, air and water, and most products are inorganic salts, so it is also called inorganic fertilizer. The advantages are high nutrient content, fast fertilizer effect, and easy storage and use; the disadvantages are single nutrients and small residual effect. Chemical fertilizer is divided by the effective nutrients it contains into five categories: nitrogen fertilizer, phosphate fertilizer, potash fertilizer, micro-element fertilizer and compound fertilizer; chemical fertilizer is an indispensable fertilizer in modern agriculture. Scientific use of chemical fertilizer can not only increase yield, but also improve quality, and can likewise play a role in building soil fertility.
