From chemistry to current events: The six macronutrients that make up a plant (N, P, K, Mg, S & Ca)

In the second of three Teaching Tools in Plant Biology spanning the topic of Plant Nutrition, we examine how macronutrients affect plant growth. Specifically, we look at (1) the availability of nutrients in the soil along with the effects of soil microbes and physical properties on their availability; (2) nutrient uptake from the external environment, … Read more

Charging ahead with plant nutrition

Teaching Tools in Plant Biology has released the first of a three-part series on the topic of Plant Nutrition, “Plant Nutrition 1: Membrane Transport and Energetics, K Nutrition and Na Toxicity”,  co-authored by Michael Blatt. This lesson starts by describing the central role of membrane transport and energetics in plant nutrition. The proton-motive force needed … Read more

What happens when “nature’s driving force” runs dry?

Leonardo da Vinci compared the movement of water in nature to the movement of blood in an animal, and concluded that, “Water is the driving force of all nature.” Five hundred years later we still can recognize the truth in this statement. However, with groundwater resources dwindling and rainfall patterns becoming irregular, could nature’s driving … Read more
