What does the term "nutrient deficiency" refer to in crops?

The term "nutrient deficiency" in crops refers to a situation where a plant does not receive adequate nutrients necessary for its growth and development. Plants require a range of nutrients, including macro and micronutrients, to perform vital functions such as photosynthesis, energy transfer, and synthesis of compounds. When a crop lacks these essential nutrients, it can result in stunted growth, poor yield, yellowing of leaves, and overall reduced plant health.

Understanding nutrient deficiency is crucial for effective nutrient management because it helps farmers identify and address the specific needs of their crops, ensuring they receive the proper nutrient balance for optimal growth. Recognizing the signs of deficiencies allows for timely interventions, such as soil testing and targeted fertilization, to improve crop health and productivity.
