Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and their external supply. These chemical elements include macronutrients (i.e., nitrogen, phosphorus and potassium), as well as micronutrients (i.e., boron, chlorine and manganese). Nutrients are often added to soil as fertilizer to increase plant growth and yield, although this can have a negative impact on the surrounding environment.
Research on plant nutrition at the Noble Research Institute focuses on understanding the molecular and physiological mechanisms underlying nutrient uptake from the soil and utilization in the plant for growth. A major objective of this research is to improve nutrient-use efficiency in plants to minimize the requirement for fertilizer and reduce the impact of agriculture on the environment.
