How many people live on earth now?
Find out by looking at a Worldometer. Ever wonder how we’re going to grow enough healthy food to feed everyone?
The N, P, K Gang
Nitrogen (N), Phosphate (P) and Potash (K) are hard workers in the plant world. Without their muscle plants would not be able to produce food, seed or even flowers.
What does each nutrient do?
N is often called the Builder. It helps plants stay green by building strong stems and healthy green leaves. Nitrogen helps the plants we eat become good for us by adding proteins we need to grow and be strong.
P is referred to as the Enforcer. It helps the plant trap and use the sun's energy to make food (photosynthesis). Plants also need P grow healthy root systems.
K is often called the Protector. Potassium protects our plants against diseases and helps them stay healthy when it is cold or dry. It also helps plants move nutrients and water in the plant to where it’s needed most.
Plants need nutrients to grow healthy and strong and they suck them from the soil like a vacuum. When the plant is harvested it takes the nutrients with it. We need to put nutrients back in the soil for new plants.
