  5. A research paper from the Lithuanian Research Centre for Agriculture and Forest entitled, “The Biological Efficacy Of The Organic Matter Blackjak On The Yield Of Potato.” The paper presents a statistical analysis showing significant positive effects on the yield, starch content and protein levels of potatoes tubers from the application of Enersol humic acid.

  6. A testimonial report on a field trial on tobacco in Greece. The treatments included nursery stock production and field grown to harvest. The results showed plants treated with Enersol showed less disease in the nursery; and in the field, taller, more robust plants, more healthy leaves and delayed flowering time allowing greater leaf development.

  7. A testimonial report on greenhouse grown tomatoes in Greece. The report shows a comparison of the significant yield increase achieved from treatment with Enersol vs. the farmers’ standard treatment. The report includes comparison photos of root system enhancement in the Enersol treated plants as well as an analysis of the economic benefit derived from Enersol.
