Hi there I will be getting a lot partially raised with what they call din dang or "fill". This is the sort of reddish/yellowish sandy cheapest option usually used for raising the level of rice fields.....though of course it is the natural soil in many places. I believe this regular fill is poor quality. (Interested in people's experience about this!) I am aware one can buy what they call din dam or black dirt, but I believe it's a much more expensive option. I believe the difference in price for me could be well in the six figures. My questions: 1. Is it possible to add minerals/fertilizer/whatever to din dang to improve it's ability to grow vegetation? 2. Would one need to amend the recipe for trees/grass/etc? thanks Cheeryble What's the recipe?
