The disclosure relates to organosulfur containing compositions, in particular di-n- propyl thiosulfonate (PTSO) and di-n-propyl thiosulfinate (PTS), di-methyl thiosulfonate, di-phenyl thiosulfonate. Such compositions are useful for as biostimulants for plants. In particular such compositions may result in increased nutrient use efficiency, increased tolerance to abiotic stress, and/or improved quality characteristics. Compositions comprising said organosulfur compounds are also provided for agricultural use. La divulgación se refiere a composiciones que contienen organoazufre, en particular tiosulfonato de di-n-propilo (PTSO) y tiosulfinato de di-n-propilo (PTS), tiosulfonato de di-metilo, tiosulfonato de di-fenilo. Estas composiciones son útiles como bioestimulantes para plantas. En particular, estas composiciones pueden dar por resultado eficiencia de uso de nutrientes incrementada, tolerancia incrementada al estrés abiótico y/o características de calidad mejoradas. Las composiciones que comprenden estos compuestos organosulfurados también se proporcionan para uso agrícola.
