Below, we provide a detailed exploration of various types of chemical fertilizers, focusing on their chemical compositions and agronomic applications:
1. Nitrogenous Fertilizers
Nitrogenous fertilizers serve as the principal source of nitrogen for plants, a critical element for essential biological processes such as photosynthesis, protein synthesis, amino acid production, and chlorophyll formation. Nitrogenous fertilizers are primarily employed to stimulate vegetative growth during the initial stages of plant development. Prominent nitrogenous fertilizers include:
Urea: Chemically represented as CO(NH₂)₂, urea is one of the most extensively utilized nitrogenous fertilizers in agriculture. Containing 46% nitrogen, it provides the highest nitrogen content among commercially available nitrogen fertilizers and rapidly hydrolyzes in soil to supply nitrogen to plants.
Ammonium Nitrate: With the formula NH₄NO₃, ammonium nitrate supplies nitrogen in both ammonium and nitrate forms, which ensures prompt nitrogen availability to plants. It is particularly suited for fast-growing crops and light-textured soils.
Ammonium Sulfate: Ammonium sulfate, represented by (NH₄)₂SO₄, supplies both nitrogen and sulfur. This fertilizer is especially beneficial for alkaline soils, as it contributes to lowering soil pH. Additionally, sulfur is instrumental in enhancing the overall quality of the produce.
2. Phosphatic Fertilizers
Phosphatic fertilizers are a primary source of phosphorus (P), an essential macronutrient that plays a pivotal role in root development, acceleration of flowering and fruiting, cellular energy transfer, and nucleic acid synthesis. Key phosphatic fertilizers include:
Single Super Phosphate (SSP): Produced from the reaction of phosphate rock with sulfuric acid, SSP is one of the earliest forms of phosphatic fertilizers. It contains approximately 16-20% water-soluble phosphorus, making it effective in ensuring phosphorus availability to crops.
Diammonium Phosphate (DAP): DAP, with the chemical formula (NH₄)₂HPO₄, is widely used in contemporary agriculture. Containing 18% nitrogen and 46% phosphorus, DAP provides a synergistic source of both macronutrients, enhancing root development and plant establishment.
3. Potassic Fertilizers
Potassium (K) is a crucial macronutrient involved in regulating osmotic balance, enhancing water use efficiency, enzyme activation, and contributing to the overall quality of agricultural produce. Potassic fertilizers are instrumental in bolstering plant resistance to diseases, environmental stresses, and improving fruit size and flavor. Major potassic fertilizers include:
Potassium Chloride (KCl): KCl is a commonly utilized potassic fertilizer containing 60-62% potassium. It is particularly effective in well-drained soils with adequate moisture, rapidly supplying potassium to plants.
Potassium Sulfate (K₂SO₄): Potassium sulfate, comprising both potassium and sulfur, is ideally suited for saline soils and arid regions. Due to the absence of chloride, it is particularly favorable for chloride-sensitive crops such as grapes and strawberries.
4. NPK Fertilizers
NPK fertilizers are balanced blends of nitrogen, phosphorus, and potassium, formulated to provide a comprehensive nutrient supply for various plant growth stages. These fertilizers support root development, vegetative growth, and enhancement of fruit and flower quality. Due to their customizable nutrient ratios, NPK fertilizers are highly adaptable for diverse crop and soil requirements. Common formulations include:
NPK 20-20-20: This balanced blend is applied during the early growth phases to provide overall nutritional support.
NPK 10-52-10: This phosphorus-dominant formulation is particularly suitable for promoting root establishment and flowering, and is used during fruit setting stages.
HS Codes for Chemical Fertilizers
Given the wide array of chemical compositions and active elements in chemical fertilizers, they are categorized under specific Harmonized System (HS) tariff codes. These codes assist customs authorities in proper classification and serve as a foundation for calculating duties and taxes. Key HS codes for chemical fertilizers include:
Urea: HS Code 310210 – A highly utilized nitrogenous fertilizer, containing the highest nitrogen concentration, and widely used in agriculture.
Diammonium Phosphate (DAP): HS Code 310530 – A potent phosphatic fertilizer that is instrumental in promoting root growth and boosting crop yield.
Potassium Chloride (KCl): HS Code 310420 – This fertilizer strengthens plant cellular structure and enhances resistance to environmental stresses.
NPK Fertilizers: HS Code 310520 – A comprehensive blend of nitrogen, phosphorus, and potassium, catering to plants' needs during different growth phases.
