The use of
bio based fertilizer & seed treatment together with soil
is vital to any sustainable
Plant nutrition is only
one of more than fifty factors which directly affect both crop yield
and quality. The availability of required nutrients, together with
the degree of interaction between these nutrients and the soil, play
a vital role in crop development. A deficiency in any one required nutrient or, a
soil condition that limits or prevents a metabolic function from
occurring can limit plant growth.
A soil nutrient management plan should include
analyzing soil deficiencies to
determine the type, application rate, application interval, and the
placement of any nutrients required to optimize short and long term
There is a significant difference between
an induced deficiency and a real soil deficiency. For
example, certain crops require the addition of molybdenum
at a specific rate for optimum growth. This is a real
deficiency. In other crops zinc or iron deficiencies, caused by high
levels of phosphorus and active calcium, can result in reduced
yield. This is an induced
when deficiencies occur, the tendency is to foliar or soil apply
copious amounts of product and hope for
a favorable result. This ad hoc approach
seldom achieves the expected result and is certainly not cost effective.
The simple fact is, diagnosis
is the first step in determining an appropriate corrective action which
many include (1) a combination of treatments or (2) a program that
incorporates several applications of different products at different application rates and intervals.
is depleted there are two methods for restoring its fertility (1) it can be left idle for several years allowing it to rebuild
naturally or (2) organic matter, in the form of
crop residue, together with a microbial based inoculant can be applied from an external source. In the latter case,
the rebuilding process is accelerated and optimal conditions for soil biological
activity and long term soil fertility are maintained.
matter is vital in rebuilding depleted soil as it ensures a continuous
energy source for soil biomass. Soil biomass,
consisting of microbes, fungi, algae, protozoa etc. (1) transform organic molecules into mineral elements that are readily
available to plants and (2) help
maintain good soil structure by transforming organic matter into
humus and producing compounds that cement
small soil particles together, promoting both
increased drainage and moisture retention.
management involves not only the physical properties and mineral
structure of the soil, but also the
balance between soil pathogens and beneficial microbes.
Beneficial microbes increase nutrient availability, reduce
disease, reduce nutrient losses, and help degrade toxic compounds.
Plants thrive or suffer, depending on the type of microbes in the rhizoshere
(the area around the roots.) In a healthy
rhizoshere, dominated by beneficial microbes, plant life and soil
life work together to produce healthy plants.
Conversely, in unhealthy soil, dominated by
optimum plant growth is unattainable.
