Nutrient "NPK" Formulations
It's All About The Nutrients...
All
plants, whether they are grown in soil or with hydroponics, require a
balance of nitrogen, phosphorous, potassium (N-P-K), and trace
elements to grow properly. These nutrients are available to
plants in soil in small amounts, but over time they get depleted and
need to be supplied separately to make up the deficit. In hydroponics,
it is all the more important to ensure that plants get the right
nutrients in the right amounts.
Hydroponics formulations are structured for specific stages of a
plants life cycle. A plants nutrients requirements vary according to
the stages of its life cycle. When plants are in the vegetative stage,
they require greater amounts of nitrogen, which is the key element in
development of leaves and stems. Deficiency of nitrogen during the
growth period leads to stunted growth with yellowing of leaves. This
is the most commonly seen deficiency in plants. During the flowering
cycle the plant requires less nitrogen and more phosphorus and
potassium.
The "NPK's"
NITROGEN
Nitrogen is essential for plant growth. Nitrogen
is a part of every living cell. The two forms of nitrogen which
plants take up are in the ammonia (NH4) and nitrate (N03) ion forms.
Most agronomic crops take up most of their nitrogen in the nitrate ion
form. Plants will utilize N in the (NH4) ion form if present and
available to the plant. Lack of nitrogen and chlorophyll means that
plants cannot utilize sunlight as an energy source to carry on
essential functions such as nutrient uptake. Research has proven that
foliar, or leaf applications of nitrogen, is one form of application
that can supplement a plants nitrogen requirements during the growing
cycle.
» Nitrogen is necessary
for chlorophyll synthesis, and as a part of the chlorophyll molecule,
is involved in photosynthesis.
» Nitrogen is also a component
of amino acids.
» Nitrogen is needed for growth
of plants.
PHOSPHOROUS
Phosphate is a very important plant nutrient (macro-nutrient) needed for the plant to complete its normal production cycle. The highest level of P in young plants is found in tissue at the growing stage. As plants mature most of the P moves into the flower and then to the seed or fruit.
» Phosphorus is
needed for photosynthesis.
» Phosphorus is necessary for
plant respiration.
» Phosphorus is essential for
energy storage and transfer.
» Phosphorus is needed for cell
division.
» Phosphorus is necessary for
cell enlargement.
» Phosphorus is essential for
several other plant processes.
POTASSIUM
An important function of Potassium is its influence in efficient water use . Potassium helps in the process of opening and the closing of plant leaf pores, called the stomata. Potassium is found in cell walls which surround stomata. Adequate amounts of Potassium can increase stress conditions on plants during drought conditions. Potassium is also responsible for producing quality crops.
» Potassium is
essential for protein synthesis.
» Potassium is important in the
breakdown of carbohydrates, providing energy for plants.
» Potassium helps to control
ionic balance.
» Potassium is important in the
translocation of minerals.
» Potassium helps plants to
overcome effects of disease.
» Potassium is essential in the
fruit formation stage.»
Potassium helps improve shelf life of
fruits and vegetables.»
Potassium is involved in the activation
of more than 60 enzymes which regulate the rates of major plant growth
reactions.
