Organic, Sustainable, Regenerative: What’s the Difference?

The terms organic, sustainable, and regenerative may seem confusing at first, but each approach has a slightly different philosophy.

Prince's plume, an indicator of high soil selenium levels

Scientists do not consider selenium to be an essential plant nutrient. However, it is beneficial because it helps plants resist stressors.

Potassium deficiency

Potassium ions are found in every living cell, probably because they are necessary to activate enzymes controlling so many crucial processes.

Phosphorus deficiency in corn

Phosphorus is associated with fruit production in the minds of gardeners because it is the most important element for germination and growth.

Manganese is an important micronutrient. It helps to activate some of the key enzyme systems in plants. But it has many other roles, too.

Magnesium deficiency symptoms on apple leaves

Magnesium serves two roles affecting plants. One is improving plant health via the soil, and the other is improving plant health directly.

Iron deficiency in peaches; note the pale leaf color

Did you know that plants need iron? No iron, no chlorophyll, and therefore no photosynthesis.
