Q: There are several kinds of compound fertilizer.: Common potash are: potassium sulfate, potassium chloride, ash and so on.

Q: How to use compound fertilizer: Compound fertilizer decomposition is slow, the seed fertilizer with seed fertilizer when the crop should be based on different crops to be fat in the rule of fertilizer in a timely manner when the supply of available nitrogen fertilizer to meet crop nutrition needs.

Q: Is the compound fertilizer alkaline?: As the crop absorbs the chemical nitrogen fertilizer in the yin, the number of cations is not equal, when the absorption of cations more than anions, can make the soil acidification fertilizer called physiological acid fertilizer.

Q: Organic fertilizer and compound fertilizer: Both compound fertilizer and organic fertilizer have their own advantages and disadvantages. Only organic fertilizer can be used in conjunction with chemical fertilizers to combine the advantages of organic fertilizers and inorganic fertilizers, while overcoming the shortcomings of organic fertilizers and compound fertilizers.

Q: China's largest compound fertilizer business in the top 20 which?: Zhonghua, middle peasants, Stanley, Yufeng, Yutian, Luxi chemical, heart to heart, day ridge, Fufeng, sunny days, Kim Jong-il, housewife, Zhongyuan Dahua, Caesar, Apollo, , Red square, three elements, lotus, diverse, Huafeng, Western, Golden Earth, six countries, Shi Fengfeng, etc.

Q: Compound fertilizer well-known brands which: National sales are better Red Quartet, Stanley, Kim Jong-il, are regular manufacturers, red Quartet or central enterprises, the products are good

Q: The role of compound fertilizer: Compound fertilizer, also known as three elements compound fertilizer, mainly nitrogen, phosphorus, potassium three elements, is the most essential elements of plant growth. Mainly used for agricultural production, the average plant fertilization three to four times a quarter, each time each plant Roughly 10 to 20 grams, watered water, then the general concentration of 2%, extensive management can also be applied after irrigation. All plants can be applied.
