1. Different nutrients, organic fertilizer contains rich organic matter and various nutrient elements, provides nutrition for crops, and is more balanced and comprehensive when used. Inorganic fertilizer is relatively single nutrient, need to rely on mix to balance fertilization.
2, the fertilizer effect period is different, organic fertilizer nutrient release is relatively slow, so the fertilizer effect period is longer. Inorganic fertilizer releases nutrients faster, so the fertilizer effect period is shorter.
3, the impact on the soil is different, organic fertilizer contains a large number of beneficial microorganisms, can promote the biological transformation process in the soil, conducive to the continuous improvement of soil fertility but also improve the soil structure. The excessive use of inorganic fertilizer can inhibit the activity of soil microorganisms, resulting in the decline of soil automatic regulation ability, the soil surface becomes dry and rigid, and easy to cause soil erosion.
4, the source is different, inorganic fertilizer is also called chemical fertilizer, short for chemical fertilizer, refers to the chemical synthesis method in the factory production of fertilizer. Organic fertilizer is the fertilizer that plants and animals become after a period of decay. It is a carbon-containing material applied to the soil to provide plant nutrition as its main function.
5, the role is different, organic fertilizer contains a large number of organic matter, its main role is to improve soil fertilizer, can improve the soil, organic fertilizer applied to the soil, organic matter can effectively improve the soil physical and chemical conditions and biological characteristics, mature the soil, enhance the soil to keep fertilizer for fertilizer capacity and buffer capacity, create good soil conditions for the growth of crops. Inorganic fertilizer is mainly composed of inorganic nutrients, which directly affects the growth and development of crops.
6, the fertilizer amount is different, organic fertilizer contains more nutrients, but the relative content is low, the fertilizer effect is longer, and the release is slow, so the use of each time is very large. Inorganic fertilizer has been purified, the nutrient is relatively simple, but the relative content is high, so the use is relatively small.
7. Fertilization effect is different. After the use of inorganic fertilizer, nutrients are released fast and easily absorbed by plants, so the fertilization effect is fast, but the fertility is not durable enough. Organic fertilizer releases nutrients slowly, so the effect is slower, but it lasts longer.
8, fertilization frequency is different, organic fertilizer is usually applied once or twice a year, long-term release of fertility. Inorganic fertilizer should be applied several times according to the growth of crops. Different crops should be planted on a piece of land in different seasons, and inorganic fertilizer should be applied to crops in each season.
