Why Astha Organic Fertilizer is Best For Organic Farming?
Saturday, December 31, 2016
Astha Neem Products are Best for Agricultural Applications
Organic Fertilizers Astha Neem Super (Neem seed cake)
• Its Contains
– N (Nitrogen 2.0% to 5.0%)
– P (Phosphorus 0.5% to 1.0%)
– K (Potassium 1.0% to 2.0%)
– Ca (Calcium 0.5% to 3.0%)
– Mg (Magnesium 0.3% to 1.0%),
– S (Sulphur 0.2% to 3.0%)
– Zn (Zinc 15 ppm to 60 ppm)
– Cu (Copper 4 ppm to 20 ppm)
– Fe (Iron 500 ppm to 1200 ppm)
– Mn (Manganese 20 ppm to 60 ppm)
– It is rich in both sulphur compounds and bitter limonoids .
• Astha Neem Super (Neem seed cake) also has the capacity to
reduce alkalinity in the soil by producing organic acids which help in removing
the alkalinity of the soil.
• The calcium and magnesium in the Neem Cake also aid in
removing alkalinity
• Astha Neem Super is 100% natural and it is compatible with
soil microbes, improves rhizosphere micro-flora which ensures the fertility of the
soil
• It improves the organic matter content of the soil, helping improve soil texture, water
holding capacity, and soil aeration for
better root development.
Astha Neem Super is a
best Denitrification Product
• The oxidation of ammonium (NH4+) to nitrate (NO3-) in the microbially
mediated process of nitrification has long been recognized as a key nitrogen
transformation process in soil–plant systems.
• Several reports show impact of nitrification on other N-transformation
processes such as NO3-leaching and reduction of NO3_ to gaseous N compounds
(denitrification ) that can reduce the availability of N for crop production.
• The impact of the nitrification process itself and
subsequent reduction of NO3_ on the release of nitrous oxide to the atmosphere,
a key greenhouse gas, has also been widely studied.
• Better timing of fertilizer N, splitting of N inputs and
use of chemicals to block nitrification in soils are strategies that have been
advocated to reduce N losses.
• Meliacin in neem helps to blocks soil bacteria from
converting nitrogenous compounds into nitrogen gas (acts as a nitrification
inhibitor) thereby prolongs the availability of nitrogen to both short duration
and long duration crops.
Astha Neem Super as Soil
pest management:
• Astha Neem cake organic manure protects plant roots from
nematodes, soil grubs and white ants probably due to its residual limonoid
content.
• Astha Neem Super is widely used in India to fertilize
paddy, cotton and sugarcane.
Using Astha Neem Oil
in pest management:
• Neem extracts can influence nearly 200 species of insects
• Some of these pests are resistant to pesticides, or are
inherently difficult to control with conventional pesticides (floral thrips ,
diamond back moth and several leaf miners).
Biological impacts of
Astha Neem Oil::
• Insect growth
regulation: Azadirachtin has a unique property of working on juvenile
hormone. The insect larva feeds and when it grows, it sheds the old skin and
again starts growing (ecdysis or moulting ) which is governed by an enzyme
called ecdysone . When the Azadirachtin enter the body of larvae, the activity of
the is suppressed and the larva fails to moult , remains in the larval stage
and ultimately dies. If the larva escapes this stage due to sub lethal dose, it
would be malformed/sterile in the pupa or adult stage.
• Feeding deterrent:
The most important property of neem is feeding deterrence. The Azadirachtin, Salanin and Melandriol
create a vomiting sensation in the insect body which prevents them eating.
Sometimes, the swallowing is also blocked.
• Oviposition
deterrent: Prevents female insects from depositing eggs. When the seeds or
grains are treated with neem seed kernel extract or neem oil Astha Killer, the insect
will not feed on them and when female comes to the egg laying period of its life
cycle, egg lying is prevented.
• Formation of chitin (exoskeleton) is inhibited
• Mating as well as sexual communication is disrupted
• Larvae and adults of insects are repelled
• Adults are sterilized
• Larvae and adults are poisoned.
Astha Neem Oil use
against different pests::
• Orthoptera
(Grasshoppers, crickets, katydids, etc ): Astha Killer 30 is a widely used neem
products act as antifeedants . Several
species of these insects refuse to feed on these plants treated with neem for several days to
several weeks. Recently it has also been discovered that neem products Astha
Killer 30 convert the gregarious swarms of locusts to solitary forms.
• Homoptera
(Cicadas, Aphids, Scale insects, leafhoppers, etc ): In leaf hoppers and plant hoppers neem products Astha Killer 15
show considerable antifeedant and growth
regulating effects. Scale insects are not much affected. In some cases,
the host plant may influence the
degree of control; this seems to apply to some white flies . The ability of certain homopterous insects
to carry and transmit viruses is also influenced infecting rice fields with tungro virus.
• Thysanoptera
(Thrips): Astha Neem Super is very effective in controlling thrips larvae which
are found in the soil. Their effect is moderate when used on adult thrips and
related pests found on plants. Astha Killer neem oil is more effective as
it suffocates these tiny creatures.
• Coleoptera (Beetles and weevils): Larvae of all kinds of
beetles refuse to feed on plants treated with Astha Killer 30. Their growth is
retarted and some soft skinned ones are killed on contact.
• Lepidoptera (Moths, skippers, millers and butterflies): Neem
products act as growth deterrents in the case of the larvae of most
lepidopterous pests. They also act as
anti-feedant.
• Diptera (Flies): Insects like fruit flies, face flies, bot
flies, house flies and horn flies are affected by Astha neem products.
• Hymenoptera (Bees, wasps, sawflies, ants etc ): larvae of
sawflies exhibit the antifeedant and growth regulatory effects.
• Heteroptera (bugs): Astha Neem products exhibit
antifeedant and growth retardant properties on bugs like rice bugs etc and
vegetable bugs .
• Plant viruses: besides insecticidal properties, Astha NeemSuper is also a promising agent for control of curl of chillies . Astha Neem Oil will interfere with
transmission of rice tungro virus; reduce transmission of tobacco mosaic virus
which is a serious pest of vegetable crops.
•• Fungi: neem exhibits antifungal properties. It prevents
powdery mildew when sprayed before the outbreak of the disease. When treated
with neem , Aspergillus flavus do not
produce aflotoxins .
