Organic fertilizer, also known as farmyard manure, contains a large amount of nitrogen, phosphorus and potassium, and must be fully decomposed when applied. Inorganic fertilizer is a chemical fertilizer. Its concentration is high and needs to be diluted when applied. Generally, inorganic fertilizer is selected for indoor flower cultivation. Many friends are not clear about what is organic and what is inorganic fertilizer, and what is the difference between the two, let's take a look together.
What are organic and inorganic fertilizers
1. Organic fertilizers are also called farmyard fertilizers. Anything that uses organic matter as fertilizer is called organic fertilizer, including human feces, manure, compost, green manure, cake fertilizer, biogas fertilizer, etc.; organic fertilizer has many types and sources , Longer fertilizer efficiency and other characteristics.
2. Inorganic fertilizers are also called chemical fertilizers. Fertilizers mainly composed of inorganic substances. It mainly includes elemental fertilizers and compound fertilizers such as nitrogen fertilizer, phosphate fertilizer and potash fertilizer. The nitrogen fertilizer contains ammonia, ammonium bicarbonate, ammonium sulfate, ammonium chloride and Urea, etc.; Phosphate fertilizers include superphosphate, calcium magnesium phosphate, and phosphate rock powder.
3. Organic fertilizers can not only provide nutrients needed for crop growth to improve the soil, but also improve crop quality, increase crop yields, promote high and stable crop yields, and maintain soil fertility. At the same time, it can increase fertilizer utilization and reduce production costs. Full and reasonable use of organic fertilizers can increase crop yields.
The difference between organic fertilizer and inorganic fertilizer
Organic fertilizers are mainly plants, and animal manures are decomposed after a period of time. It can also be called green manure, which has a wide range of sources. Inorganic fertilizers are fertilizers produced by chemical synthesis, including nitrogen, Phosphorus, potassium, compound fertilizer.
After the organic fertilizer is used, it takes effect quickly and is easily absorbed by plants, but the fertility is not long-lasting; after the inorganic fertilizer is fertilized, the effect is slower, but the time is longer.
3. Impact on land
The nutrient elements contained in organic fertilizers are mostly in an organic state, and crops are difficult to use directly. They must be slowly released through the action of microorganisms to supply nutrients to crops; if inorganic fertilizers are used too much, the surface of the land will become dry and compact. And it is easy to cause soil erosion, lack of minerals, and have great damage to the environment, and excessive use will cause the soil to become more barren and lack a lot of nutrients.
