Preliminary Tests with Surfacants Fail to Show Increase in Either Growth or Survival of Scotch Pine Seedlings
It has been theorized that the addition of a small amount of surfactant, a wetting agent, to the nutrient medium reduces the surface tension of the water and results in increased penetration, spreading, and dispersion of the nutrients. It also might be expected to lower the energy requirements involved in absorption and translocation by the plant, resulting in plant growth stimulation. In recent years a number of agricultural workers have investigated the possibilities of using surface active agents to give increased yields of forage, field, and vegetable crops. Results at the University of Wisconsin 1- indicated greatly increased production of vegetable and field crops the year of application as well as the year following application.
