Comparative Study of Biostimulant Properties of Industrially and Experimentally Produced Humic Substances

Demand for new biological technologies in agriculture is ever growing, particularly with respect to the need of restoring soil organic matter and fertility. Products natural origin are developed stimulate plant growth productivity. Humic substances (HS) decay products living matter, high molecular weight complex structure. Nowadays, HS industrially produced from various materials like peat, lignin, compost. The objective this study make a comparison impact different on development. In total, eight were used; four extracted commercially available products. To evaluate stimulating effect, three species plants used (Triticum aestivum, Sinapis alba, Lepidum sativum). tests carried out Phytotestkit plates, germinating seeds solutions concentrations dark, or without added nutrient solution. Then, parameters measured. All tested showed increase at least some compared control sample. Significant differences effect depending their found.
