Seaweed fertilizer Vs compound fertilizer
 
Seaweed fertilizer or compound fertilizer? Nowadays, many farmers use compound fertilizer, but others use seaweed fertilizer. Some farmers say compound fertilizer is good? Some say seaweed fertilizer is good? Is seaweed fertilizer good or compound fertilizer good? Let's go and find out!
 
What is compound fertilizer
 
Compound fertilizer refers to chemical fertilizer containing two or more nutrient elements; Urea is an organic compound composed of carbon, nitrogen, oxygen and hydrogen. It is a white crystal with very single composition, that is, it can only provide nitrogen for crops.
 
1、 Advantages of compound fertilizer
 
1. There are many kinds of nutrients with high content. There are many kinds of nutrients in compound fertilizer, and the content of pipe components is also high. For example, diammonium phosphate is an 18-46-0 compound fertilizer, which is expressed as a binary compound fertilizer containing 18% nitrogen (n) and 46% phosphorus (p205). It has more nutrients and higher content than simple nitrogen fertilizer or phosphorus fertilizer.
 
2. Good physical properties and convenient application. The particles of compound fertilizer are relatively solid, dust-free, average particle size and volume, small moisture absorption, and easy to store and apply. Compound fertilizer is suitable for both mechanized and manual application.
 
Disadvantages of compound fertilizer
 
2、 Disadvantages of compound fertilizer
 
1. The proportion of nutrients is fixed, which is difficult to meet the needs of crops. Many crops have different needs for nutrients in each growth stage, and there are great differences in raw soil fertility and nutrient release in various regions. Therefore, the compound fertilizer with relatively fixed nutrient ratio is difficult to meet the requirements of all kinds of raw soil and crops at the same time.
 
2. The release speed of various nutrients is different from the requirements of crops. The movement laws of various main nutrients in raw soil are different. For example, the mobility of nitrogen fertilizer is greater than that of phosphorus and potassium, but the aftereffect of fertilizer is far longer than that of phosphorus and potassium. Therefore, it is difficult for compound fertilizer to meet the special requirements of crops for nutrients in a certain era in terms of nutrient location and release speed.
 
3. The cost is high. The cost of using compound fertilizer is higher than that of simple fertilizer. Preparing fertilizer with the same content of compound fertilizer with simple fertilizer can reduce the cost by 20-30%.
 
Because seaweed fertilizer is harmless to people and animals and has no pollution to the background, it has been listed as a special fertilizer for organic agricultural commodity production overseas. It is a natural, efficient and green fourth generation fertilizer. As the original producer of marine organic matter, cauliflower has strong adsorption capacity, can concentrate 440000 times of its own marine things, and its nutrition is extremely vast and balanced.
 
What is seaweed fertilizer
 
Seaweed fertilizer extract comes from a variety of marine algae. Long ago, seaweed fertilizer has been used as a food additive to improve the nutrition of human and animals. At the same time, seaweed fertilizer is also a close industrial raw material and natural cosmetics.
 
Now, the application of seaweed fertilizer extract in sustainable agriculture is an area of global interest. Seaweed fertilizer extract is a close component of plant culture medium, which has been widely recognized.
 
Seaweed fertilizer has the effects of strong rooting, stress resistance, cold resistance, continuous cropping resistance and enhancing crop immunity. At the same time, it can activate microorganisms in raw soil, increase fertilizer efficiency and significantly increase crop yield and quality. Since entering the market, seaweed fertilizer has been favored by growers with its image of high efficiency and environmental protection, and has become one of the new fertilizer products with rapid progress recently.
 
Advantages of seaweed fertilizer
 
The core function of seaweed fertilizer is pure natural cauliflower extract alginic acid, which is rich in seaweed fertilizer polysaccharides, phenolic polymers, mannitol, glucoradishine, plant growth regulators and other natural bioactive things required for crop growth and development, as well as a large number of organic substances, more than 40 mineral elements such as potassium, calcium, magnesium, zinc and iodine and abundant vitamins. The plant derived seaweed fertilizer extract has excellent affinity with crops and can be quickly used for reference by crops.
 
1. Compared with traditional fertilizers, seaweed fertilizer has comprehensive nutrition, balanced growth after crop application, significant yield increase effect, and rare element deficiency.
 
2. Seaweed fertilizer includes a large number of disease resistance factors and special components, which has double effects of fertilizer and medicine. The stress resistance and disease resistance of crops were significantly enhanced after application, and foliar spraying could improve the absorption effect of chemical fertilizer.
 
3. Seaweed fertilizer contains a large number of highly active components with high plant absorption rate. After application, crops grow vigorously, which can increase yield and crop quality.
 
4. Seaweed fertilizer includes abundant organic matter and slow-release factor, with long fertilizer effect, which can improve the micro ecology of raw soil, activate soil, promote roots and resist continuous cropping.
 
5. Seaweed fertilizer is natural, safe and pollution-free.
 
Seaweed fertilizer is a pure natural green organic fertilizer, which has been widely used in foreign countries, and is used in green organic vegetables and fruits. It can be said that seaweed fertilizer is the trend of green organic vegetables and fruits in the future
