Abstract: | Summary Cucumber (Cucumis sativus) plants were grown in Hoagland solution to which 20 to 2000 ppm of a soil fulvic acid (FA) were added. The addition of 100
to 300 ppm of FA produced highly significant increases in the growth and development of above and below ground plant parts,
in the uptake of nutrient elements (N, P, K, Ca, Mg, Cu, Fe and Zn), and in the formation of numbers of flowers per plant.
Effects of adding 500 and more ppm of FA were less beneficial. |
