I am starting a farm near Tirunelveli, Tamil Nadu. At Tirunelveli, I had seen numerous small “Municipal Micro-Composting” facilities in my locality. Last week I had visited some of them to check the feasibility of procuring it. In a couple of such facilities, I could see small plastic wrappers and empty medicine sheets which got me a little worried. Upon speaking to the officials from the municipal corporation, they assured me that all non-compostable materials shall be sieved/filtered before they are being sold. The price of compost seem to be affordable as well.
I do know some of my questions are geography-specific and pertinent to local practices. But would love to hear your thoughts on the following.
Do any of you have experience using such compost ?
Have any of you tested them at a lab for presence of any chemicals/harmful substances which could potentially be detrimental soil health ?
Are there any standard practices that I can undertake to test the quality of the compost visually or from texture ? There seems to be more than 10 such facilities from where I could source the compost. Being new to farming/ag , its difficult to assess the quality of compost by just looking at them.
Thanks in advance,
