Just as humans need vitamins and minerals to thrive so do
plants. The nutrients our garden plants require are called essential elements.From the air, plants get oxygen, hydrogen and
carbon.Earth soils add two other types
of nutrients plants need to thrive. They are broken down into two categories.
The categories are Macro nutrients and micro nutrients. Macro and micro
nutrients or soil nutrients are also referred to as trace elements. The most critical
macro nutrients are Nitrogen, Potassium and Phosphorus.You will often see these nutrients listed on
fertilizer bags. They are the numbers with the corresponding letters N, P, K.
These letters are the periodical names for these elements. The N stands for
Nitrogen. Plants basically use nitrogen to help them grow larger through the
act of photosynthesis. Phosphorus or P is the element helps in root development
and is essential for fruit development. Potassium or K also helps with root
growth and flower development as well as helping sugar, water and other
nutrients travel through the plant. Other macro nutrients such as magnesium,
calcium and sulfur typically aren’t on bags of fertilizer with the big three
“N, P, K”, but are list under other ingredients along with inert maters. These other macro nutrients are also used by plants but in smaller amounts depending
on their specific needs. Micro nutrients consist mainly of iron, manganese,
molybdenum, zinc, chlorine, copper, baron and nickel. These nutrients are used
as backups and in combination to the big three to help the processes of growth.
Easy ways to get some of these fertilizers organically are found in stores as
Blood meal, which contains nitrogen and iron. Bone meal contains Potassium,
calcium and nitrogen. Fish emulsion and seaweed may also be used for quicker
release if plant needs a boost.
