How to Increase Yield by Applying Potassium Fertilizer Reasonably to Chinese Cabbage
How can Chinese cabbage increase yield by applying potassium fertilizer? The yield-increasing effect of applying potassium fertilizer to Chinese cabbage is obvious. Test results show that: under the same conditions of nitrogen and phosphorus fertilizer, adding potassium fertilizer (50% potassium sulfate) at 18 kg/mu to Chinese cabbage gave a yield increase rate as high as 33.2%, with an average increase of 159 kg of Chinese cabbage per kg of potassium sulfate. It enhances disease resistance. Applying potassium fertilizer can...

Correct application methods and precautions for slow-release nitrogen fertilizer
Traditional nitrogen fertilizer management for strong-gluten wheat is generally divided into two applications. The first is a portion of nitrogen fertilizer applied before wheat sowing in conjunction with plowing, accounting for 60%-70% of the total nitrogen application; the second is a topdressing applied from the spring green-up stage to the stem elongation stage of wheat in conjunction with watering, accounting for 30%-40% of the total fertilizer application. Some apply it before wheat overwintering...

Apply phosphate fertilizer this way, and crops will resist drought and increase income
Crops absorb phosphorus fastest during the seedling stage, and the seedling stage is also the critical period for phosphorus nutrition. If phosphorus is deficient during the seedling stage, it will affect the later growth of the crop. In our province, spring temperatures are low, soil microbial activity is weak, and the release of soil available phosphorus is low. In addition, low soil temperature weakens the root system's ability to absorb nutrients, making it difficult to meet the crop's needs during the critical period of phosphorus nutrition. ...
