Abstract
The dynamics of plant nutrients are vital for sustainable crop production, as nutrient availability in the soil is shaped by factors such as soil properties, environmental conditions, and agricultural practices. Soil organic matter acts as a nutrient reservoir and supplies food for soil microorganisms. However, over time, reliance on straight fertilizers or imbalanced fertilizer applications without incorporating organic matter such as FYM, green manuring or vermi-composting can lead to nutrient mining. In the Indo-Gangetic Plain of India, there is also a significant deficiency of many essential plant nutrients, which impacts crop yield potential and deteriorates soil health. To address these issues, it is important to identify the major causes of nutrient mining and explore sustainable management options. Balancing plant nutrient concentrations in the soil through practices such as the inclusion of organic amendments, precise fertilizer application and crop rotation can enhance soil health and improve crop productivity.
