What are the types of fertilizers: fertilizers and manure?
First, a wide range of farm manure and a wide range of sources, the number of large, easy to local materials, local use, the cost is relatively low. Organic fertilizer is characterized by a comprehensive range of nutrients, it contains not only nitrogen, phosphorus, potassium, Fertilizer but also contains calcium, magnesium, sulfur, iron and some trace elements.
Second, chemical fertilizers refers to the chemical method of manufacturing or mining of ore, processed by the fertilizer, also known as inorganic fertilizer,
1, including nitrogen fertilizer, phosphate fertilizer, potash fertilizer, fertilizer, fertilizer, etc., they have the following common characteristics: simple ingredients, Fertilizer high nutrient content; fertilizer quick, fat fierce; some fertilizer acid and alkali reaction; generally free of organic matter , No soil fertility effect. There are many kinds of chemical fertilizers, and the nature and application method are quite different.
2, trace element fertilizer
Trace element fertilizer refers to chemical fertilizers containing trace elements such as B, Mn, Mo, Zn, Cu, and Fe. In recent years, agricultural production, the lack of trace elements become increasingly serious, many crops have emerged trace elements deficiency, such as corn, rice zinc deficiency, fruit trees lack of iron, boron, rapeseed boron. The application of trace element fertilizer, Fertilizer has been a significant increase in yield and economic benefits, the agricultural sector throughout the country have been the application of micro-fertilizer into the agenda.
Biological fertilizers, through the activities of microbial life, so that crops get a specific fertilizer effect of the product, also known as inoculants or bacteria fertilizer, Fertilizer which itself does not contain nutrients, can not replace the fertilizer.
Fertilizer classification methods and types of many, the nature of the composition is also very different. Generally divided into inorganic fertilizers, organic fertilizers and bio-fertilizer. Organic fertilizers, also known as chemical fertilizers, such as nitrogen fertilizer, fertilizer, potash fertilizer, fertilizer and so on; organic fertilizer called farm manure, such as manure, green manure, cake fertilizer, fertilizer and composting, etc .; biological fertilizer, also known as slender fertilizer, Plant nutrition conditions of fertilizer, can not directly supply nutrients. According to different application measures but also divided into base fertilizer, top dressing, fertilizer and foliar fertilizer. There is also a classification is based on crop requirements of the elements of the division, including large, medium, trace element fertilizer, a large number of elements such as nitrogen fertilizer, phosphate fertilizer, potash fertilizer; in the amount of fertilizer such as calcium fertilizer, magnesium fertilizer and sulfur; Element fertilizers such as iron fertilizer, manganese fertilizer, boron fertilizer, zinc fertilizer, copper and molybdenum fertilizer. In addition, the compound fertilizer can be divided into two yuan, three yuan or more compound fertilizer, compound fertilizer is actually two or three kinds of major nutrients such as nitrogen, phosphorus, potassium fertilizer in general, multiple fertilizer is not only Containing a large number of nutrients nitrogen, phosphorus and potassium, but also contains a variety of trace elements of fertilizer. The production of compound fertilizer is a variety of single element fertilizer or multi-element fertilizer in accordance with the needs of different crops on the nutrient, a certain percentage of mixing, and after a certain production process made of particles, and then packaged from the fertilizer, such as Vegetables for fertilizer, fruit for fertilizer, wheat special fertilizer and so on. There is also a new type of fertilizer known as controlled release fertilizer, also known as smart fertilizer or fool fat, such as controlled release nitrogen fertilizer, controlled release of phosphate fertilizer, controlled release fertilizer.
