Abstract:
1. A system suitable for dispensing controlled amounts of either a volatile liquid or a non-volatile liquid into a soil, said system comprising: a liquid reservoir for holding a liquid agrochemical, said reservoir including an outlet for dispensing said liquid agrochemical; a distribution manifold in communication with said outlet of said reservoir, said distribution manifold being connected to a plurality of dispensing tubes designed to inject said liquid agrochemical into the soil; and a plurality of pressure reducing members, each of said pressure reducing members being in communication with a corresponding dispensing tube, the pressure reducing members creating a pressure reduction between the distribution manifold and each of the dispensing tubes, wherein, when dispensing a volatile liquid agrochemical, the pressure reducing members cause the volatile liquid agrochemical, prior to entering the plurality of dispensing tubes, to partially vaporize but not intermix with, the liquid agrochemical contained in the distribution manifold thus creating a heat exchange effect which cools the liquid agrochemical contained in the distribution manifold.
