How much nitrogen fertilizer do you need for red meat and pomelo?

Nitrogen (N) is the most important element influencing the growth and yield of red-fruited pomelo. It is mostly present in organic form, with a small part of nitrate nitrogen and ammonium nitrogen present. Nitrogen is an important element that constitutes a living substance, and it is also an important element that affects the metabolic activity and growth results of red meat pomelo plants. It is a main component of amino acids and proteins, an essential component of cell membranes, genetic material nucleic acids, chlorophyll, enzymes, Plant hormones, vitamins, etc. also contain nitrogen. On the plants, the nitrogen stored in the leaves was the most, accounting for about 40% of the whole tree, while the branches accounted for about 30%, the roots accounted for about 10%, and the fruits accounted for about 20%. Red-fruited pomelo has the greatest demand for nitrogen. With sufficient and appropriate nitrogen, it has a strong growth, dark green leaves, normal flowering, high yield, and good quality.

Within a certain range, the amount of nitrogen applied is directly proportional to the yield. Nitrogen deficiency, abnormal shoots, yellow leaves, fall off, tree weakness, easy to form a "small old tree", the output plummeted. However, when the amount of nitrogen fertilizer is too high, the growth is excessively prosperous, the flowering results are reduced, the fruit turns color, the ripening is late, the skin has a small amount of juice, the meat becomes thicker, and the acidity increases. Therefore, in order to ensure high yield and quality of red pomelo, it is very important to control the appropriate amount of nitrogen fertilizer.

The application of nitrogen fertilizer will affect the absorption of other elements by the plant. When the nitrogen content in the leaves is high, the calcium and magnesium contents are also high, which inhibits the absorption and utilization of potassium, zinc, manganese, copper, boron, molybdenum, and especially phosphorus.
