Agriculture is a broad and multidisciplinary subject.  We have tried to group the subjects in Earthwise Academy as intuitively as possible, but there is a lot of overlap and some information doesn’t seem to fit under any particular heading.  The “hard to classify” but “important to know” subjects are grouped under this General Knowledge heading.  Happy Hunting!

The Law of Minimums, Maximums and Balance

The supply of mineral nutrition to plants is a crucial and highly dynamic process – nutrient shortages can and do impact plant growth, health, and fruiting at critical times in the growing season.

The mineral wheel illustration is a very useful visualization of the complexity of soil-mineral-plant relationships.  It is interesting that the same relationships exist in animals as well.  We can harness this complexity for crop production through the promotion of self regulating biological systems in the soil.

Mycorhizzal Associations

The term Mycorrhizae refers to the symbiotic association between a living plant and a beneficial fungus (usually basidiomycete).  This association is common in naturally vegetated, undisturbed areas, especially forests.  Different plant species have the ability to associate with differing species of fungi to form associations.

 

Mycorrhizal associations are important to plant life world wide, but have only recently been commercialized for crops and ground covers.
