Using farmyard manure, compound fertilizer, water-soluble fertilizer and other fertilizers can make sugarcane sweeter. Characteristics of sugarcane’s fertilizer requirements: Sugarcane’s demand for nitrogen, phosphorus and potassium throughout its life is that nitrogen is the most, phosphorus is the least, and the amount of potassium is second only to nitrogen.

1. Farmyard manure. The characteristic of organic fertilizer is that it contains relatively comprehensive nutrients. It not only contains nitrogen, phosphorus, potassium, but also calcium, magnesium, sulfur, iron and some trace elements. Most of these nutrients are in the state of organic matter and are difficult to be directly absorbed and utilized by crops. They must be decomposed and decomposed through chemical and physical effects in the soil and fermentation of microorganisms, so that the nutrients are gradually released, so the fertilizer effect is long and stable.

2. Compound fertilizer refers to a chemical fertilizer containing two or more nutrient elements of nitrogen, phosphorus and potassium. Compound fertilizer has the advantages of high nutrient content, few side components and good physical properties. For balanced fertilization, Improving fertilizer utilization efficiency and promoting high and stable crop yields play a very important role.

3. Water-soluble fertilizer Water-soluble fertilizer is a multi-component compound fertilizer that can be completely soluble in water. It can be quickly dissolved in water and is more easily absorbed by crops, and its absorption and utilization rate is relatively high. More importantly, it can be used in facility agriculture such as sprinkler and drip irrigation to achieve the integration of water and fertilizer, thereby saving water, fertilizer and labor.
