Methods and Technical Key Points for Applying Potassium Fertilizer in Orchards
How should potassium fertilizer be applied in orchards? What methods are there? Traditional orchard fertilization methods often focus only on applying nitrogen fertilizer while neglecting phosphorus and potassium fertilizers, especially potassium fertilizer. Potassium deficiency in orchards can affect flower bud differentiation, the tree's cold resistance and fruit coloring, and can also reduce yield and fruit quality. When potassium deficiency is severe, the leaf margins or entire leaves scorch, spreading from the middle and lower parts upward and downward. After the leaves dry up, they can remain hanging on the branches for a long time. The leaves that have not withered curl and shrink, flower buds are small, and fruit color is poor.

How to correctly apply herbicides during the maize seedling stage
How should herbicides be applied to maize seedlings? Please give guidance. For post-emergence chemical weed control in maize, herbicides must be strictly selected and mixed and applied according to the instructions. In plots with severe weeds, the dosage may be increased by 15-20% above the rate stated in the instructions. Method: for foliage treatment, it must be done before maize reaches the 6-leaf stage and before weeds reach the 2...

What fertilizer is best to apply before and after harvesting persimmon trees?
What fertilizer is best to apply before and after harvesting persimmon trees? Why apply fertilizer even after harvesting? Before and after fruit harvest, persimmon trees should be given nitrogen and potassium fertilizer to promptly replenish the tree's nutrients and raise its nutrient level, which helps the tree flower and fruit normally the following year. The specific method is: apply pre-harvest fertilizer 15~20 days before harvesting the persimmons, mainly with quick-acting, fast-dissolving nitrogen and potassium fertilizer. For trees bearing 50 kg or more, apply 2~3 kg of urea and 0.5~1 kg of potassium chloride or potassium sulfate per tree, or 1~1.5 kg of potassium sulfate, broadcast after rain or dissolved in 50~60 times clear water and drenched on. Apply post-harvest fertilizer within 10~15 days after harvesting, mainly with complete nitrogen, phosphorus and potassium fertilizer and high-quality organic fertilizer. Along with clearing the orchard, remove all kinds of weeds around the persimmon tree, then dig a ring-shaped trench 25~30 cm deep and 25~30 cm wide around the tree's drip line, thoroughly stir and mix 2~3 kg of nitrogen, phosphorus and potassium compound fertilizer with 40~50 kg of composted, fully rotted human, livestock and poultry manure, apply it into the ring trench, and cover with soil.

What precautions should be taken when applying potassium sulfate?
What should be noted when applying potassium sulfate? Please give guidance. Potassium sulfate is a high-quality potassium fertilizer with a relatively high potassium content. Potassium sulfate is a white crystalline substance, with a K2O content generally between 50% and 52%. It is easily soluble in water, has low hygroscopicity, and does not easily cake, giving it better physical properties than potassium chloride. Potassium sulfate is widely suitable for various...
