The absorbtion of nutrients in certain relative
proportions results in a healthy plant. When the proportions are
suitable the nutrient medium is said to be "balanced". When ratios
between nutrients are too wide, deficiency conditions are created.
Nutrients, even though present in satisfactory amounts and
proportions, may not be absorbed by the plant unless the "reaction"
of the solution as regards acidity and alkalinity is satisfactory.
The reaction is measured in terms of the pH scale.
The neutral point
is that when acidity and alkalinity are equal and neutralize the
effect of each other.
The neutral point is represented by pH 7.0;
below this value the solution is acidic and above it is alkaline.
Many crop plants prefer a reaction slightly on the acid side-pH 6.0
to 6.5 and extreme values are in the neighbourhood of 4.0 on the acid
side and 9.0 on the alkaline side.
High EC of soil enables uptake of
nutrients
from the soil. Excess irrigation and chemical fertilization
increases salinity of soil.
Nature Life Science find out the solutions for above problems by
introducing an innovative product. |
