The difference between sulfur-based compound fertilizer and chlorine-based compound fertilizer is divided according to the source of potassium. The compound fertilizer can be divided into sulfur-based compound fertilizer and chlorine-based compound fertilizer. The chlorine-based compound fertilizer refers to the compound of potassium source using potassium chloride. Fertilizer; Sulfur-based compound fertilizer refers to a compound fertilizer made of potassium sulfate from potassium source or dechlorinated from potassium chloride, and the chloride ion content cannot exceed 3%. Their traditional differences are shown in the following table.
It is not difficult to see from the above table that sulfur-based compound fertilizers and chlorine-based compound fertilizers have certain differences in composition, effect, and application methods, especially in terms of application range, such as economic crops, onions, leeks, and garlic. For the crops that are more sensitive to sulfur deficiency, such as vegetables or rapeseed, sugar cane, peanuts, soybeans and kidney beans, the application of sulfur-based compound fertilizer is better.
For aquatic vegetables and hemp crops, because chloride ions are necessary for hemp crops, it can promote fiber development, enhance fiber resilience, and apply chlorine-based compound fertilizer. The following is a detailed discussion of sulfur-based compounding. The difference between fertilizer and chlorine-based compound fertilizer.
- There are different dechlorination processes in the production process of sulfur-based compound fertilizer. The chlorine content is generally controlled within 3%, while the chlorine-based compound fertilizer contains a large amount of chlorine.
- Different application scopes, chlorine-based compound fertilizers have adverse effects on the yield and quality of trees (such as citrus), potatoes, sugar beets and tobacco, and can not be used for avoiding chlorine crops, but chloride ions promote photosynthesis. And fiber formation and other effects, especially suitable for fiber crops such as hemp. Sulfur in sulfur-based compound fertilizers is an essential medium element for crops, so sulfur-based compound fertilizers are suitable for various crops.
- Different application methods, sulfur-based compound fertilizer can be used as base fertilizer, top dressing, seed fertilizer and top dressing. Due to the high chlorine content, chlorine-based compound fertilizer can not be used as seed fertilizer and root dressing. It can only be used as base fertilizer and top dressing.
- Different fertilizer effects, chlorine-based compound fertilizers form a large amount of residual chloride ions in the soil. After being applied to the soil, the soil salt ion concentration can be increased, which is not suitable for saline-alkali soil. Sulfur-based compound fertilizer is a necessary medium-nutrient nutrient for crops, which can effectively improve soil sulfur deficiency and provide sulfur nutrients directly to crops.

Rapid test kits are designed for use where a preliminary screening test result is required and are especially useful in resource-limited settings.
• High quality
• Quick (10 minutes to 2 hours) and easy to perform .
• Tests based on agglutination, immuno-chromatographic, immuno-dot, and/or immuno-filtration techniques.
• Are suitable for individual or a limited number of samples, and require little or no additional equipment, which make them more economical than ELISAs in fully equipped laboratories.
• Possibility to store at room temperature for an extended period of time.
• Same-day results provide timely treatment possibility.
[Test Principle]
Urobilinogen:Urobilinogen with diazonium salt produce red violet dyes in strong acid medium.
Bilirubin:The direct bilirubin with dichlorobenzene diazonium produce azo dyes in acid medium.
Ketone:The acetoacetic acid and sodium nitroprusside cause reaction in alkaline medium,which produces red violet compound.
Blood:Hemoglobin acts as peroxidase. It can cause peroxidase release neo-ecotypes oxide (O).(O) oxidizes the indicator and make the color change subsequently.
Protein:It is based on a specific pH indicator attracted by cation on protein molecule,the indicator further ionized and make the color change.This phenomenon is called protein-error-of -indicator principle.
Nitrite:Nitrite and aromatic amine are diazotized to form a diazonium compound.The diazonium compound reacts with tetrahydrobenzo(h)quinolin 3-phenol produce the red azo dye.
Leukocyte:Pyrrole amino acid ester produce free phenol under the hydrolysis of esterase in neutrophile granulocyte,the free phenol couple with phenyl diazonium salt produce purple azo dyes.
Glucose:The glucose oxidized by glucose oxidase catalyzes the formation of glucuronic acid and peroxide hydrogen.Peroxide hydrogen releases neo-ecotypes oxide(O)under the function of peroxidase.(O)oxidizes tetramethyl benzidine, which make the color change.
Specific Gravity:Methyl vinyl ether and maleic acid copolymer is weak acid (-COOH) exchanger,the M+ cation (the major is Na+) in urine reacts with the exchanger and release hydrogen ion,hydrogen ion reacts with indicator produce color change.
pH:The method of pH indicator is applied.
Ascorbic Acid:Ascorbic acid deoxidizes the 2.6-dichlorphenolindophenol dye into colorless in alkaline medium.
Microalbumin:Sulfone phthalein dye has high sensitivity to microalbumin by the method of protein error.
Creatinine:Creatinine with 3,5-Dinitrobenoic acid produce violet compound in alkaline medium.
Calcium:Calcium ion reacts with methyl bromothymol blue produce color change in alkaline medium.
