How to distinguish true and false biological organic fertilizer

Bio-organic fertilizer is one of the most technically advanced products in China. It has recently been recognized for its unique effects of promoting growth, disease prevention and disease resistance. According to research, the key factor for the bio-organic fertilizer to produce a significant effect is “living + special”. Functional + microbial strains, because its technology is too strong, the general fertilizer "administrative supervision department" detection technology can not keep up, leading to market fish, the farmers can not tell, the Nanjing Agricultural University, the College of Resources and Environment to overcome the soil continuous cropping obstacles research team 12 Associate Professor and more than 70 masters and doctors have long been engaged in the prevention and control of bio-organic fertilizers for soil-borne diseases of economic crops such as watermelon, cucumber, tomato, pepper, eggplant and yam. Based on experience, a set of identification methods is designed for reference.

Looking at the packaging, is it standard?

1. Product registration certificate: It has the microbial fertilizer registration certificate number of the Ministry of Agriculture (Note: there is no registration right in the provincial department), the correct method: “microbial fertilizer (registration year) pro word (number) number” or “microbial fertilizer (registration year) ) quasi-word (number) number";

2. Product technical indicators: The number of effective viable bacteria (CFU) ≥ 0.2 billion / gram, the Ministry of Agriculture is only allowed to mark ≥ 0.2 billion / gram, 0.5 billion / gram at the time of registration (strictly, on the last day of the preservation period must be Reach this value). In order to cater to the market, some companies deliberately mark billions of dollars. This is unscientific (current technology is difficult to achieve) and is wrong.

3. Product expiration date: The national regulations are greater than 6 months. As the preservation time of bio-organic fertilizer products is prolonged, the number of effective viable bacteria will continue to decrease, and it is irresponsible to label the expiration date too long.

Looking at the material, is it even?

1. If the water content of the product is too high or too low, it is not conducive to the survival of the strain. Judging method: Grasp a handful of fertilizer and observe it under the sunlight. The Yin tide is a group, and the dry and gray are all abnormal products.

2. "Organic fertilizer nutrition" suitable for the growth of special functional strains should be a package type, which is composed of various organic nutrients (such as: fermented vegetables, soy flour, etc.), and the traces of raw materials can be seen under light. Or you can smell the special smell of raw materials.

Seeing the effect, is it efficient?

Test method: add a small amount of water to adjust the bio-organic fertilizer into a pellet, place it in the refrigerator and freeze it into ice cubes, and take it out the next day to dissolve it. Three times, the strain in the fertilizer will freeze or decrease greatly; this is Use it to compare and test the original product, observe the difference in the same field, the difference is obviously good fertilizer, the difference is not obvious, indicating that the product has problems, it is recommended to give up.

Applications :

Food & Drink
Salt (Sodium Chloride) is a well known flavour, preservative and a texturiser. 

PDV, Granular and Tablet salt all play their part in the food manufacturing processes either as a food ingredient or as a water softening salt used on the plant. 
Chemicals & Manufacturing Used in many manufacturing processes and as a raw material in the chemical industry

Textiles & Dyes

Salt(Sodium Chloride) is added when dying cotton and viscose textiles to assist in fixing the dye. In dye manufacture, salt can be used to bring the dye out of solution at the end of the manufacturing process, a technique known as 'salting out'. Salt can also be used in the 'standardisation' of dye mixes, to ensure uniformity of dye strengths between different batches. Finally, salt is sometimes used as a grinding agent to reduce the dye compounds to a powder.
