What precautions should be taken when applying rare earth micro-fertilizers in walnut orchards?
The content of rare earth elements in plants is very low, and the content varies greatly among different organs, generally distributed as: root > stem > leaf > flower > fruit and seed. About 80% of the rare earth elements absorbed by plants are concentrated in the roots. Applying rare earth micro-fertilizer to walnut trees can promote the root system's absorption of nitrogen, phosphorus, potassium and

Precautions for Applying Photosynthetic Microelement Fertilizer to Walnut Trees
Pictured: Walnut. Photosynthetic microelement fertilizer is a nutritional foliar fertilizer. In addition to containing the three essential elements for plants - nitrogen, phosphorus, and potassium - as well as various trace elements such as calcium, magnesium, sulfur, iron, manganese, zinc, aluminum, and copper, it also contains a photorespiration inhibitor (namely photosynthetic fertilizer), and has the effect of improving

Rational Fertilization of Fish Ponds and Methods for Applying Nitrogen Fertilizer in Rice-Fish Paddy Fields
Fertilizing fish ponds is one of the main techniques for regulating the aquatic environment of ponds and cultivating natural fish food organisms. If the water is too lean, the fish raised will almost always have big heads, small tails, thin backs and little flesh; using too much fertilizer will degrade water quality, not only affecting fish growth but even causing

The Latest Remedies for Phytotoxicity in Cotton
Cotton is a crop that receives a relatively high number of pesticide applications. During application in cotton fields, wrong pesticide varieties, excessive concentration, improper application methods and other reasons often cause phytotoxicity in cotton, leading to decline in cotton variety quality, reduced yield, or even total crop failure. So how should cotton phytotoxicity

The Latest Method for Applying Carbon Dioxide Gas Fertilizer to Greenhouse Grapes
The main raw materials for plant photosynthesis are carbon dioxide and water. The organic matter and starch produced by photosynthesis are deposited within the plant as nutrients for the plant's own growth. Therefore, the quality of photosynthesis also affects the growth and development of plants. Nowadays, grapes

Why does over-applying nitrogen fertilizer reduce crop yields, and how much nitrogen is actually needed?
Nitrogen is one of the essential nutrient elements for crops, and supplying nitrogen fertilizer in appropriate amounts can increase crop yields and improve quality. But if nitrogen fertilizer is over-applied, crops will instead reduce yields. What is the reason for this? How much nitrogen do crops actually need? Over-applying nitrogen fertilizer causes the carbohydrates produced by crop photosynthesis

Wood ash is a high-quality potassium fertilizer; pay attention to these issues when collecting and applying it
Wood ash is the residue left after burning plant materials such as crop straw and dead branches and fallen leaves. According to rough estimates, the ash from burning plants in China each year exceeds 20 million tons. If calculated at an average of 5% potassium oxide, this is about 1 million tons, equivalent to 2 million tons of potassium sulfate, which

The role of applying silicon fertilizer to rice, the dosage per mu, and precautions
Silicon is called the fourth nutrient element. As rice yields continue to increase, especially in areas where the soil's available silicon content is not rich, applying silicon fertilizer to rice has become an effective measure for stable and high yields. So what effect does silicon fertilizer have on rice? How much to use per mu? What are the
