Sodium molybdate is commonly used as a fertilizer in agriculture, particularly for crops that require molybdenum as a micronutrient. Molybdenum is an essential element for plants, although it is needed in small quantities. Sodium molybdate is a convenient source of molybdenum that can be easily absorbed by plants.

Here are some applications of sodium molybdate in crops:

1. Molybdenum Deficiency Correction: Some soils may be deficient in molybdenum, leading to poor crop growth and reduced yield. Adding sodium molybdate to the soil or applying it as a foliar spray can help correct molybdenum deficiencies and promote healthy plant growth.

2. Nitrogen Fixation: Molybdenum plays a vital role in the nitrogen-fixing process carried out by leguminous plants, such as soybeans, peas, and clover. It helps the plant convert nitrogen gas from the atmosphere into a usable form that enriches the soil. Sodium molybdate can be applied to these crops to enhance nitrogen fixation and improve overall plant health.

3. Enzyme Activation: Molybdenum is a cofactor for several enzymes involved in plant metabolic processes, including nitrogen metabolism and sulfur assimilation. Sodium molybdate supplementation can ensure proper enzyme activation, leading to improved nutrient utilization, better protein synthesis, and enhanced overall plant growth and development.

4. Crop Quality Improvement: Molybdenum influences the quality of certain crops, such as cruciferous vegetables (e.g., cauliflower, broccoli), by affecting their sulfur metabolism. Adequate molybdenum levels achieved through sodium molybdate application can enhance the flavor, aroma, and nutritional value of these crops.
