 Impact
of chemical fertilisers on activities of enzymes:
 |
Influence of
NK fertilisers on enzymes like nitrate reductase,
protease and urease are being monitored. Such
studies are fruitful in making conclusion
on dosage, optimum interval and efficiency
of NK fertilisers |
|
Influence of trace elements
like Zn, Mn, Cu, Fe, Mo, Al, Hg, Pb, Ni and
Cd on aryl sulfatase, acid and alkaline phosphatase
are being recorded |
|
Vertical distribution of
enzymes like urease protease, aryl sulfatase,
acid and alkaline phosphatases in various
agro climatic zones are being recorded |
EXPERIMENT ON LIMING
:
New experiments are in progress
to decide the lime dose based on buffering capacity
of tea soils. The buffering capacity was estimated
using four different approaches namely SMP, Woodruff,
Mechlich and Adams & Evan.
EXPERIMENT
ON PHOSPHORUS :
New experiments were laid out at Nilgiris, Anamallais,
Wayanad, Central Trivancore and Koppa regions to
study the influence of citric acid on the availability
of soil available phosphorus. This study also compares
the availability of phosphorus versus placement
of rock phosphate also.
EXPERIMENT ON ENERGIZED WATER (VI-AQUA) :
Influence of electromagnetically treated
water on growth and productivity of tea is being
studied.
BIO-POWER AND BIO-FORCE
:
New molecules of organic origin like Bio-Power and
Bio-Force are being evaluated for their performance
on growth and productivity of tea.
STUDIES ON TOXICITY
OF ZINC :
A potted plant experiment is in progress
to find out the toxicity levels of zinc. The study
also aims to account for the symptoms of zinc toxicity.
PLANT SAP TECHNIQUE
:
The laboratory is trying to develop this technique
to asses fertility levels of soils based on plant
sap analysis.
ANALYTICAL SERVICE
:
Besides conducting research, we are offering
analytical service primarily to our members, firm
members and also to non-members at a nominal charge.
The service include.
|
Soil analysis
for fertility status and pH |
|
Leaf analysis for nutrient
content like N, P, K, S, Ca, Mg, Zn, Mn, B,
Cu, Ni, Fe, Na and Cl |
|
Organic manure analysis
for all the above mentioned parameters in
addition to moisture, pH and EC |
|
Analysis of active ingredient
content in various herbicides, fungicides
and pesticides |
|
Analysis of wetting agents |
|
Analysis of straight and
mixed fertilisers for UPASI/FCO specification |
|
