Seed coating

I used to make seedballs but never had a real good method to make it and didn't use it reliably. While buying some vegetable seeds, used to see a coating, not sure what kind of material is used to coat that seeds, but saw some videos in Youtube which pours a thick liquid and while mixing with seeds, you get a decent coating, that looked interesting. But it looked like they had used chemicals and some polymer for coating seeds and that was not acceptable to me.

Recently came across some youtube videos of seed coating from Tamilnadu Agriculture University (TNAU). This used a 4% solution of gum arabic powder as binder and coating material was not very clear.

Gave the problem to chatGpt and they suggested gum arabic powder, neem oil,garlic paste, turmeric powder and 1 drop of soap, wet seeds with this solution and coat with ash. At first just used gum arabic powder,turmeric and 1 drop of soap. Wetted the seedes with this solution and applied ash 3,4 times each time before applying, wetting with gum arabic solution.

Since gum arabic binds the ash well, coating was easily made, but whether ash coating will remain in sunlight and outside conditions to be seen. ChatGpt suggests to add 70% ash and 30% red soil. Initially had tried with red soil, but since the particle size was bigger it was not sticking very well. ChatGpt has given a solution to mix soil with water and allowing the sediments to settle.

Wanted to use the seedball for surface seeding in the coming rainy season, last time I put the seeds on surface and then put compost on top of it, but most of the seeds were taken by ants, immediately, wanted to avoid that.
