Scientific application methods and technical key points for potash fertilizer
Potassium is one of the three essential fertilizer elements. Many vegetables often require more potassium than nitrogen and phosphorus; well-grown vegetables contain potassium at 2.5%-7% of their dry matter, higher than their nitrogen and phosphorus content. Most vegetables absorb more potassium than nitrogen; for example, the nitrogen-to-potassium ratio absorbed by cucumber is 1:(1.5-1.7), by pumpkin is 1:2.1, and by tomato is 1:...

Application Methods of Potassium Fertilizer in Vegetable Cultivation
There are many types of potassium fertilizer, and different types have different application methods. Commonly used potassium fertilizers include potassium chloride, potassium sulfate, potassium-magnesium fertilizer and plant ash. Potassium chloride and potassium sulfate are physiologically acidic fertilizers and should be applied together with lime and organic fertilizer. For chlorine-sensitive crops such as potatoes, potassium chloride and potassium-magnesium fertilizer with high chlorine content should not be applied...

Detailed Explanation of Fertilizer Types and Application Methods (Part 6)
Achievement of Shandong Agricultural University: The fertilizer coating controlled-release technology involves spraying a uniform controlled-release film onto the surface of crop-specific compound fertilizer or urea granules. Its core technology lies in the film material and corresponding additives. By adjusting the formula, the number and size of pores on the film can be set to control nutrient release. Controlled-release fertilizer...

Application Methods and Technical Key Points of High-Efficiency Organic Fertilizer
I. How to Apply High-Efficiency Organic Fertilizer to Vegetables 1. Application Rate: According to the nutrient requirements of various vegetable crops, apply 60-100 kg per mu as base fertilizer for each crop of vegetables. Baosheng High-Efficiency Organic Fertilizer is mild in nature, and applying more is unlikely to cause fertilizer burn; for vegetables, melons and fruits with high economic value or high yield, the application rate may be increased by 20-50%. Baosheng...

Characteristics and Application Methods of Water-Soluble Fertilizers Explained in Detail
The "7 major issues" to watch out for when applying foliar fertilizers: Issue one, the spraying concentration must be appropriate. The spraying concentration of foliar fertilizer directly affects the result; if too high, it easily burns crop leaves; if too low, it not only increases the workload but also fails to achieve the spraying effect, so during spraying it must be based on the crop...

What fertilizer is best for azaleas? Fertilizer selection and application methods
What fertilizer is best for azaleas? Please give guidance. Azaleas are fertilizer-loving plants. In addition to the main nutrients nitrogen, phosphorus and potassium, they also need trace elements such as boron, copper, molybdenum and zinc. For azaleas, fertilizers with mild strength and long-lasting effect are suitable. For home azalea growing, ox horn, ram horn and animal hoof pieces can be used; these fertilizers contain 12%-15% nitrogen and 0.2%-8% phosphorus, and also contain a small amount of potassium and trace elements. Thin hoof pieces take effect 1 month after application, while thick hoof and horn pieces show fertilizer effect after 2 months, and the fertility can last 6-8 months. When using them, they can be buried at the edge or bottom of the pot along with repotting or changing pots. Cake fertilizer is also a relatively complete fertilizer in terms of nutrition. The nutrients in cake fertilizer generally contain 2.1%-7.6% nitrogen, 0.54%-3.3% phosphorus and 0.5%-2.7% potassium. Generally speaking, soybean cake and peanut cake contain more nitrogen, while rapeseed cake and cottonseed cake contain more phosphorus. They must be fully fermented before application. Fertilizer made by composting livestock manure and tree leaves can be mixed into the growing medium when repotting.
