Rain Dependent Agriculture India
Water is one of the key elements in agriculture
and agriculture requires significant amount of
water most of which is rain fed or harvested.
Seeds and fertilizers fail to achieve full
potential if plants are not watered
regularly. With nearly 20 of the worlds
population to feed, India has access to only 4
of fresh water resources, out of which around 90
is used for agriculture.
With 140 mHa of cultivable land in India, 42
falls in drought prone areas.

• Around 55 of Indias arable land dependent on
  rain, the monsoon season could sway economic
  activity in the agriculture sector and industries
  linked to it.
• The overall Indian economy remains very
  vulnerable to the monsoon, since poor rainfall
  can significantly reduce agricultural production.

Alsta Hydrogel polymer is a potassium
polyacrylate based hydrogel polymer absorbing
about 500 600 times water of its own weight, is
organic, non-toxic and biodegradable, mandated to
be beneficial for farmers in improving crop
yield, especially in dry drought
conditions. In arid areas, the use of Alsta
Hydrogel in sandy soil (macro-porous medium)
increases soil water-holding capacity, and
significantly improve the quality of plants.

Key Benefits
01
Super absorbent polymer absorb water to about 500
600 times of its own weight, forming water
beads or crystals
02
Acts as a mini water reservoir for plants,
trapping irrigation run-off and rainfed water to
release during prolonged dry conditions
03
Absorbs soil nutrients which are then utilized by
plants reducing overall fertilizer and pesticide
usage by 30 35
04
Does not alter soil chemical composition. Highly
effective in drought hit areas with efficient
water usage

How to Use
01
Plough dry or semi-dry soil, add Alsta Hydrogel
dosage in the soil by broadcasting
02
Irrigate land via drip, drench or manual
sprinkling, and level land completely.
03
Alsta Hydrogel stores absorbed water, forming gel
around roots.

Working Principle
Mini water reservoirs
Hydrogel absorbs irrigation water to up to 400
500 times its weight forming mini water
reservoirs which Release water upon root demand
viz., osmotic pressure difference.
Alsta Hydrogel particularly reduces irrigation
frequency and compaction tendency, it stop
erosion and water run-off and increases soil
aeration and microbial activity promoting
sustainable plant growth.

Benefits
15 - 20 saving in fertilizer usage when mixed
dry into fertilizer preparations, hydrogel reduce
fertilizer (NPK) leaching.
50 reduction in irrigation frequency with the
increased uptake of water
Chemtex Speciality Limited 2021
13
Benefits
Alsta Hydrogel can absorb 400 - 600 times DM
water than its own weight drawn into the molecule
by osmosis
402 increase in soil water retention capacity
with high performance super absorbent polymer
