Which is better to apply potassium sulfate or potassium nitrate to tomatoes in the open air?
In the case of the same amount of potassium application, potassium nitrate has a better yield-increasing effect, especially when the soil is lacking in nitrogen and potassium, the effect of applying potassium nitrate to vegetable farmers is particularly prominent. When the nitrogen content in the soil is very high, such as when the hydrolyzed nitrogen in the soil is higher than 300mg and potassium is lacking, the effect of potassium sulfate in increasing production is better; the effect of applying potassium sulfate to the soil with sulfur deficiency is significant. Greenhouse vegetable soil should monitor the effective sulfur content of the soil. When the effective sulfur content of the soil is higher than 100 mg, pay attention to control the application of sulfur-containing fertilizers including potassium sulfate.
