Neem

[itchybromusic]

you do have to be careful when you use neem oil , it does have a half life & will be absorbed though the plant leaves & root system 

 

using neem cake is a lill diff as it's not plant available & needs to be consumed by microbes B4 the plant gets it 

in general anything that comes out the ass of worms or microbes is better than when it went in 

 

there is def some oil left in the neem cake which you can make a tea with & use in the same way as a oil spray or drench 

in a soil mix @ around 1/4 cup to 14lts of soil there shouldn't be any issue with that amount as it will be consumed 

quite quickly , i also top dress small amounts of neem cake pretty regular though the grow 

 

cannabis is a bit of a dynamic accumulator & will take up most of what's in the soil , good or bad so the last month you back off most

things , 

 

also good to add to plant health when spraying anything , like oils , that plants don't really like , for instance , last night plants here got a 

aloe , silica , fulvic & Dr bronners hemp castile peppermint soap spray , each one of these items are killing bugs or increasing plant health 

some actually do both 

 

to much of the one thing is not good even when it's good for you , just like humans , eat to much shit & your body works in a shitty way

but even drinking to much water can cause probs = ever seen an over watered plant , humans can be over watered as well 

 

In rare cases, drinking an extreme amount in a short time can be dangerous. It can cause the level of salt, or sodium,

in your blood to drop too low. That's a condition called hyponatremia. It's very serious, and can be fatal. 

You may hear it called water intoxication.

It’s the Azadirachtin (sp?) in the neem which is the gold.....for the most part.

“Enviro Neem” available on eBay au, has one of the highest ppm’s Of Aza.....that I have used or seen available in a Neem oil extract.

Hand held whizz mixers are great for emulsifying the neem with bronners or whatever you are using. Be cautious with silicone as an emulsifier as the high ph kills Aza..........

Neem cake

Neem cake organic manure is the by-product obtained in the process of cold pressing of neem tree fruits and kernels, and the solvent extraction process for neem oil cake. It is a potential source of organic manure under the Bureau of Indian Standards, Specification No. 8558. Neem has demonstrated considerable potential as a fertilizer. For this purpose, neem cake and neem leaves are especially promising. Puri (1999)[not specific enough to verify], in his book on neem, has given details about neem seed cake as manure and nitrification inhibitor. The author has described that, after processing, neem cake can be used for partial replacement of poultry and cattle feed.

Components Edit

 

Neem cake has an adequate quantity of NPK in organic form for plant growth. Being a totally botanical product it contains 100% natural NPK content and other essential micro nutrients as 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.

 

According to research calculations, neem cake seems to make soil more fertile due to an ingredient that blocks soil bacteria from converting nitrogenous compounds into nitrogen gas. It is a nitrification inhibitor and prolongs the availability of nitrogen to both short duration and long duration crops.

 

Use as a fertilizer Edit

 

Neem cake organic manure protects plant roots from nematodes, soil grubs and white ants probably due to its residual limonoid content. It also acts as a natural fertilizer with pesticidal properties. Neem cake is widely used in India to fertilize paddy, cotton and sugarcane. Usage of neem cake have shown an increase in the dry matter in Tectona grandis (Teak), Acacia nilotica (Gum Arabic), and other forest trees.

 

Neem seed cake also reduce alkalinity in soil, as it produces organic acids on decomposition. Being totally natural, it is compatible with soil microbes and rhizosphere microflora and hence ensures fertility of the soil. Neem cake improves the organic matter content of the soil, helping improve soil texture, water holding capacity, and soil aeration for better root development.

 

Pest control Edit

 

Neem cake is effective in the management of insects and pests. The bitter principles of the soil and cake have been reported to have seven types of activities (a) antifeedant ( attractant © repellent (d) insecticide (e) nematicide (f) growth disruptor and (g) antimicrobial.

 

The cake contains salannin, nimbin, azadirachtin and azadiradione as the major components. Of these, azadirachtin and meliantriol are used as locust antifeedants while salannin is used as an antifeedant for the housefly.

great post SE & me too Faith 

 

Now neem is great but don't over do it , oil or cake , more is not always better

 

of cause there are some probs that could force the need for using more than in

general use , but regular small amounts as part of your IPM will help to control

any possible infestation 

 

as far as neem oil cost , consider not all oil would have been extracted from the crushed neem seed 

& making a neem cake tea would give you very similar results as a oil spray would 

 

neem cake is def part of the nutrient make up & IPM of the soil i mix @ 1/4 cup per 14lts
