In autumn, it is the peak period of fertilizer use for a year, but many farmers do not pay attention to the application of potash fertilizer. For example, many farmers generally plant winter wheat in the autumn and only apply urea and diamine, and the amount of potassium fertilizer is very small, and many people do not even use it at all. As one of the three major elements, the importance of potash cannot be ignored. What is the use of potash One is to improve stress resistance. Potassium participates in a number of physiological activities during plant growth, can promote carbohydrate and nitrogen metabolism, control and regulate the activity of various mineral nutrients, activate the activities of various enzymes, control the transportation of nutrients and water, and maintain cellular Internal pressure, thereby preventing plants from withering. The second is to improve quality. Since the application of potassium fertilizer can improve the stress resistance of crops, it plays a very important role in ensuring high and stable crop yields. For corn, for example, potassium fertilizer can improve the quality of corn stalks and prevent lodging. The third is to increase production. Due to the high potassium content in the original soil in some areas, many farmers have not realized the important effect of potassium on yield. Do you want to use potash fertilizer The application of potassium fertilizer has not attracted everyone's attention, and it has a great relationship with the content of potassium fertilizer in the soil. my country's soil potassium supply capacity varies greatly in different regions, generally low in the south and high in the north, and low in the east and high in the west. However, since everyone has not paid attention to the application of potassium fertilizer for a long time, the soil potassium content in many areas is decreasing. So, should we use potash fertilizer? Take a look at the soil. The potassium content in our soil is slowly decreasing. In addition, proper amount of potassium fertilizer should be applied to the northern soil. Second, look at the crop. As potassium plays an important role in increasing the protein and carbohydrate content of crops, it is recommended to use potassium fertilizer for general economic crops, especially legumes, potato crops, cotton, hemp, tobacco and fruit trees. Third, look at external nutrient input. In recent years, it has been advocated to return straw to the field. This is because the potassium content of straw is relatively high, and it is easy to release, which can supply a large amount of potassium to the soil. How to choose potash "three brothers" There are many types of potash fertilizers, and the mainstream varieties on the market mainly include potassium sulfate, potassium chloride, and potassium dihydrogen phosphate. Potassium sulfate is more expensive than potassium chloride because it is not easy to agglomerate, has better physical properties, is more convenient to use, and has higher production costs. Therefore, potassium sulfate is generally applied to crops with higher economic value. However, potassium chloride, because it contains chlorine, should be used to avoid chlorine crops. Such as beets, sugar cane, potatoes, grapes, watermelons, tea trees, tobacco, citrus and other chlorine-free crops, it is generally not suitable to use potassium chloride. Potassium dihydrogen phosphate contains both phosphorus and potassium, no impurities and residues, and all nutrients can be absorbed by crops. It plays an important role in increasing crop production and income and improving stress resistance. I need to remind farmers that the price of potash itself is higher than that of urea and phosphate fertilizer, so when you buy it, you must not buy fake and inferior products instead of greedy for cheap.

potty training or for older pets with incontinence issues. They are made
of multiple layers of absorbent material, including a top layer that
wicks moisture away from the surface to keep pets dry, and a bottom
layer that prevents leaks and spills. These pads are typically used
indoors, and they can be placed on the floor or in a designated area
where pets can relieve themselves. Once soiled, the pads can be easily
disposed of and replaced with a fresh one. Disposable pet training pads
are available in various sizes, and they can be used for dogs, cats, and
other small pets. Disposable Pet Training Pads,Disposable Puppy Training Pads,Disposable Pet Pee Pads,Disposable Waterproof Pet Training Pads Honghu Danielle Sanitary Material Co., Ltd. , https://www.daniellecn.com
