Examples of essential elements include calcium, magnesium, and sulfur. Calcium fertilizers have a long history of application in agriculture. With the development of high-quality and high-efficiency agriculture, calcium deficiency is becoming increasingly serious, and calcium fertilizers are receiving more and more attention.
In southern my country, the types of crops and soils that are effective for magnesium fertilizers have expanded significantly, and magnesium deficiency is showing a growing trend, highlighting the importance of magnesium fertilizers. Generally, acidic soils, swampy soils, and sandy soils are prone to magnesium deficiency. Sulfur is an element that crops require in large quantities, comparable to phosphorus, and in some crops, even exceeding phosphorus requirements. Sulfur deficiency in crops can affect their normal growth, leading to a decline in yield and quality.
