Macronutrients and Micronutrients

There are 14 mineral nutrients found in soil that are required for a plant to thrive. These nutrients are divided into 3 categories:

Macro – Nitrogen Phosphorous Potassium.

Secondary –  Calcium Magnesium Sulfur.

Micro –  Boron Chloride Cobalt  Copper Iron Manganese Molybdenum Zinc. /fusion_popover]

Each category plays an essential role in bringing a plant to it’s fullest potential. Those required by plants in large amounts are called macronutrients; these are nitrogen, phosphorus, potassium, calcium, magnesium and sulfur. Plant micronutrients, needed in tiny amounts, include boron, chloride, copper, iron, manganese, molybdenum, nickel and zinc.

Organic vs Inorganic

Inorganic (Mineral Based Nutrients) v. Organic (Animal/Plant Based Nutrients) – When it comes to plants, a nitrate molecule is a nitrate molecule. There is absolutely no difference between a nitrate molecule from a mineral source and a nitrate molecule from an organic source. Therefore, when it comes to providing nutrients for plants, an inorganic or an organic fertilizer provide a plant with exactly the same nutrient compound.

Fact: Soil needs to break down organic elements into inorganic elements before a plant can absorb them.

Organic nutrients have to be converted into inorganic forms by soil bacteria and fungi before plants can use them, so they typically are more slowly released, over time. In contrast, inorganic fertilizers provide nutrients that are immediately available for use by the plant. Simply put, the nutrients that organic and non-organic fertilizers provide to the plant are exactly the same, just one takes longer for the plant to absorb than the other.
