Soybean plants dying from Sclerotinia infection.

Essential Nutrients for Plants - How do nutrients affect ...

Micronutrients are boron, chlorine, copper, iron, manganese, molybdenum, and zinc. A very few plants need five other nutrients: cobalt, nickel, silicon, sodium, and vanadium. Each essential nutrient affects specific functions of plant growth and development (Table 1). Plant growth is limited by the nutrient that is in the shortest supply (Fig. 1).

The Carbon Cycle - NASA

The fast carbon cycle is so tightly tied to plant life that the growing season can be seen by the way carbon dioxide fluctuates in the atmosphere. In the Northern Hemisphere winter, when few land plants are growing and many are decaying, atmospheric carbon dioxide concentrations climb.
