The Importance of Reasonable NPK Ratios

The reasonable NPK ratios are very necessary for crops’ growing. NPK compound fertilizer is available in liquid or granular form, and some granular fertilizer is in a slow-release formula. A numbering system is used to define the percentages of the three essential plant nutrients. For example, a 20-20-10 fertilizer would contain 20 percent nitrogen, 20 percent phosphorus and 10 percent potassium. Secondary nutrients and trace elements are typically listed.Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years.

Most NPK compound fertilizer is rated based on the percentage of nitrogen, phosphorous and potassium, using a rubric called NPK. The amount of nitrogen will encourage growth of stems and leaves by promoting protein and chlorophyll. More flowers, larger fruits and healthier roots and tubers will result from added phosphorus, which also helps plants resist certain diseases. Finally, potassium thickens stems and leaves by fostering protein development. This means, for example, that vegetables would do better with an NPK ratio that is different from what is best for roses or orange trees.
