Evaluation of cowdung liquid manure and fresh cowdung slurry

In rainy season, I had applied cowdung slurry to cowpea,brinjal and ladys finger and found excellent results. I just wanted to evaluate fermented cowdng slurry with fresh cowdung slurry.

So I am planting some ladys finger and rice plants and will apply fresh cowdung slurry and fermented cowdung slurry once in a week and will see which shows better results.

Fermented cowdung slurry was prepared by filling a drum with 150 litre water and putting around 10Kgs of fresh cowdung and 5 handfuls of horse gram powder, 4-5 bananas and a handful soil. This was fermeted for 2 days.

Fermented cowdung slurry being prepared....

The one with stick was applied with fermented cowdung liquid and other one with fresh cowdung slurry.


Two plants on the right side is applied with fermented cowdung liquid and other two was applied with cowdung slurry

Could not complete these experiments due to various reasons...majorly because of water shortage, watering was delayed...

Three years ago during Apr-May i had bought chicken manure for my Nutmeg trees. They brought it in plastic sacks each costing about 60Rs inclusive of transportation and carrying them to individual trees, about 5 bags per tree. The manure was fresh at that time and fearing intense smell i did not open the bags at that time. Soon monsoon started and that year there was very good rains. The manure was still in the bags unopened, after about 4 months during Aug-Sep i opened the bags. By this time the manure had completely turned into compost, filled with thousands of tiny earthworms. i was planning to plant some bananas during that time and i withdrew some bags from the nutmeg trees and took out the compost for the newly planted bananas. The growth was amazing. although later the banana trees were attacked by pests (chelli) on the stem and many were severely damaged, the effect of this compost was really impressive. underneath the nutmeg trees we could see clusters of tiny roots wherever the manure was spred, and so was on banana trees.

This experience give me an idea that manure should be applied after a bit of composting. I see the process you are doing is some kind of accelerated composting and will give better results than applying the cow dung or any other manure directly.

One I bought some cowdung from outside, it had lot of plastics, so stopped it completely. I am trying to manage with whatever cowdung I can get from my cow and my helper's cow.

Chicken manure is very good from nutrients point of view, but they may contain lot of chemicals. Once a farmer told, his coconut trees got affected after applying chicken manure bought from farms and agriculture scientists also suggested not to use them.

Cowdung slurry or coqdung based liquid manure is easy to apply and if they don't want in large quantities, it will be a benefit. I am not sure, if I will be able to apply them in my farm, may be in the backyard, I can experiment and make it practical.

Thanks for the insights, it looks like, we have lot more work to do on documenting and seeing the results. Probably at the end, we may find that Fukuoka's method is the best, apply chicken manure in the paddy field, and leave the orchards with just cover crop and many varieties of trees.
