Ravinnekäyttötehokkuus, often translated as nutrient use efficiency, refers to the ability of a plant or an ecosystem to utilize available nutrients for growth and biomass production. It is a crucial concept in agriculture and environmental science, impacting crop yields, fertilizer application, and nutrient cycling in natural environments. High nutrient use efficiency means that a larger proportion of the nutrients absorbed by the plant is incorporated into its tissues, leading to better growth with less nutrient input. Conversely, low nutrient use efficiency implies that a significant amount of absorbed nutrients is lost or not effectively utilized, potentially leading to nutrient deficiencies in plants or excess nutrient runoff into water bodies.

Several factors influence nutrient use efficiency. These include plant species, genetic characteristics, growth stage, environmental conditions such as soil type, pH, moisture, and temperature, as well as management practices like fertilization methods and timing. For instance, plants adapted to nutrient-poor soils often exhibit higher intrinsic nutrient use efficiency. In agricultural settings, optimizing these factors can enhance crop yields while minimizing fertilizer waste and environmental pollution. Research in this area focuses on breeding crops with improved nutrient uptake and utilization, developing precision agriculture techniques to deliver nutrients exactly where and when they are needed, and understanding the complex interactions within soil microbial communities that affect nutrient availability and plant uptake. Measuring nutrient use efficiency typically involves comparing nutrient uptake with biomass production or yield.
