- 环境科学
- 农业科学
- 粮食系统分析
背景情况:
- 可持续饮食与农业实践有关,大部分环境影响都发生在农场.
- 环境指标对于评估和促进可持续粮食生产和消费至关重要.
- 目前的指标往往不足以反映多样化,局部化的农业系统.
研究的目的:

Key Elements for Plant Nutrition
21.3K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Dietary Connections

In biological systems, most metabolic pathways are interconnected. The cellular respiration processes that convert glucose to ATP—such as glycolysis, pyruvate oxidation, and the citric acid cycle—tie into those that break down other organic compounds. As a result, various foods—from apples to cheese to guacamole—end up as ATP. In addition to carbohydrates, food also contains proteins and lipids—such as cholesterol and fats. All of these organic compounds are used...
