Micronutrient fertilizers are essential for plant health and growth, providing nutrients that are required in smaller quantities compared to macronutrients like nitrogen, phosphorus, and potassium. Here's a description of common micronutrient fertilizers:

1. Zinc Sulfate:

   • Description: Zinc sulfate is a common source of zinc for plants. It helps in enzyme activation, protein synthesis, and chlorophyll production.
   • Appearance: White crystalline powder.
   • Application: Can be applied to soil or as a foliar spray.

Micronutrient fertilizers are designed to supply essential trace elements that are required by plants in small amounts but are crucial for their growth and development. Here's a detailed description:

1. Key Micronutrients:

   • Iron (Fe): Vital for chlorophyll synthesis and photosynthesis. Iron deficiency can cause interveinal chlorosis (yellowing between veins of older leaves).
   • Manganese (Mn): Important for photosynthesis, respiration, and nitrogen metabolism. Deficiency symptoms include interveinal chlorosis in young leaves.
   • Zinc (Zn): Necessary for enzyme function, protein synthesis, and growth regulation. Deficiency leads to stunted growth and leaf mottling.
   • Copper (Cu): Plays a role in photosynthesis, respiration, and lignin synthesis. Deficiency can cause leaf curling and poor growth.
   • Boron (B): Essential for cell wall formation, pollen germination, and sugar transport. Deficiency symptoms include brittle leaves and poor fruit development.
   • Molybdenum (Mo): Required for nitrogen fixation in legumes and nitrate reduction. Deficiency can cause poor plant growth and yellowing of older leaves.

2. Forms of Micronutrient Fertilizers:

   • Chelated Compounds: Micronutrients are complexed with chelating agents (e.g., EDTA, DTPA, EDDHA) to improve their availability and prevent them from becoming insoluble in the soil.
   • Sulphates: Simple salts like zinc sulfate, copper sulfate, and manganese sulfate that are directly applied to soil or used in foliar sprays.
   • Oxides: Oxide forms of micronutrients (e.g., copper oxide, zinc oxide) are less soluble but can be used in some formulations.
