| Agricultural Uses | The elements that help plant growth are called plant
nutrients. There are seventeen essential nutrients, some
of which are required in large quantities (macro
nutrients) and some in as small a quantity as about 50
ppm, which are called micronutrient or minor nutrients.
These are chlorine, iron, boron, manganese, zinc,
copper, molybdenum and nickel.
The solubility and availability of micronutrient ions
are affected by the presence of complexing and chelating
agents secreted from roots and produced during
microbial degradation of residues.
Each micronutrient plays a specific role in the
growth and development of the plant. Most
micronutrients, especially the transition metals (Zn, Fe,
Mn, Cu, Mo and Ni) are constituents of many
metalloenzymes. They function in key metabolic events
such as chlorophyll synthesis, photosynthesis,
respiration, protein synthesis, nitrogen fixation,
assimilation of nitrates and sulphates, etc. Micronutrients
are, therefore, responsible for key processes in plants
including those aimed at efficient utilization of even
major nutrients.
Each micronutrient has specific functions in a plant
system. Micronutrients are, to an extent, present in soils.
Several soil factors influence their availability to plant
absorption, thus determining their deficiency. However,
both the deficiency and the requirement are dynamic
factors. They vary with the type and properties of the
soil, characteristics of the plant, the cultivation and
management practices, the level of crop productivity, the
supply of fertilizers, etc
Continuous removal of nutrients from soil reserves,
the ever increasing intensity of crop cultivation with the
use of high yielding varieties, and adoption of intensive
fertilizer applications (major nutrients) cause deficiency
of one or more micronutrients in soils and/or plants.
Deficiency of micronutrients in plants is associated
initially with hidden deficiency and subsequently visible
deficiency. The deficiency that has not expressed itself in
the form of any signs or symptoms is called hidden
deficiency. In the initial stages of such a deficiency, the
plant adjusts itself to the situation. Diagnosing this
deficiency is extremely difficult even by leaf analysis,
unless the situation is critical. However, any positive
crop response to the application of micronutrients is
indicative of the existence of hidden deficiency. In fact,
hidden deficiency in various crops is far more widespread
than it is recognized.
Visible deficiency occurs when the plant system is
unable to cope up with the hidden deficiency internally.
The plant then loses its nutrient balance and expresses a
deficiency situation by characteristic visible symptoms.
By this time, the problem of micronutrient deficiency is
already aggravated. The application of micronutrients at
this stage would remedy the situation, but plants may not
give yields to their potential. Hence, to obtain high
yields, micronutrients have to be applied prior to the
occurrence of hidden deficiency and not after that of
visible deficiency symptoms.
Quantification of micronutrient deficiency: A
micronutrient deficiency is often quantified based on the
analysis of the soil/plant samples. The critical limits
established for the soil and plants under experimental
conditions are used to express the extent of deficiency in
the field conditions. Despite limitations, this method is
universally followed.
Most research on micronutrients has been mainly
focused on a single nutrient basis (e.g , zinc deficiency or
iron deficiency). Fertilizers made of a single
micronutrient are used to correct specific deficiencies.
Deficiency of more than one micronutrient in the same
soil/crop can also exist. The intensity of deficiency varies from mild to severe. The problem of multimicronutrient
deficiency could be more than what is currently
recognized and is bound to increase further as more areas
and crops come under investigation
Multimicronutrient fertilizers are being largely used on
crops grown under intensive cultivation systems,
plantation crops, cash crops, vegetables, fruits,
ornamentals, etc
Micronutrients are applied in many ways, including
foliar application, seed treatment, root dipping of
transplanted seedlings and application with pesticides.
However, the most popular method is to apply
micronutrients with primary nutrients that the farmer
regularly uses. This helps him save the time he would
have otherwise spent for micronutrient application. Also,
by this method, the micronutrients can be uniformly
applied when mixed with a much larger volume of
fertilizers. |
