Chemical fertilizer
Fertilizers are essential substances in agricultural production, providing plants with the nutrients they need to grow. There are many different types of fertilizers, each with its own unique characteristics and applications. Today, I’d like to share the main characteristics of chemical fertilizers.
Chemical fertilizers, commonly referred to as “chemical fertilizers,” are likely familiar to everyone. They are fertilizers produced through chemical and physical methods that contain one or more of the nutrients required for crop growth, and have become an indispensable input in modern agricultural production.
Chemical fertilizers can be further classified into macronutrient fertilizers (nitrogen, phosphorus, potassium), secondary nutrient fertilizers (calcium, magnesium, sulfur), micronutrient fertilizers (zinc, boron, molybdenum, manganese, iron, copper, chlorine), and compound fertilizers containing two or more elements.
Common nitrogen fertilizers include urea and ammonium bicarbonate; phosphorus fertilizers include calcium superphosphate and calcium-magnesium phosphate; potassium fertilizers include potassium chloride and potassium sulfate; and compound fertilizers include diammonium phosphate, potassium dihydrogen phosphate, and N-P-K ternary compound fertilizers.
Chemical fertilizers are high in nutrient content, take effect quickly, are convenient to use, and are clean and hygienic (compared to farmyard manure); however, they tend to be nutritionally limited, and long-term use can easily lead to adverse effects such as soil compaction, soil acidification, or salinization.
