  • Patent number: 6834461
    Abstract: A method for modulating plant growth is provided whereby seedlings that are grown in containers such as blocks are fertilized at lift. Prior to fertilization, the block, which has numerous plug cavities, is restrained. The seedlings, which are grown in plugs formed in plug cavities, are supported and a bore is drilled into the bottom of the plug. The bore extends to the top of the plug to produce a small port, which serves as a port for expulsion of air during the injection operation. The fertilizer is measured in a metering roller and is then pneumatically injected into the bore in the plug. Upon completion of the injection, the bore is closed to reduce the loss of fertilizer from the plug. The various operations may be automated or performed manually.

  • Patent number: 5199978
    Abstract: The present invention provides a process for removing elemental sulfur from fluids such as refined petroleum products transported through pipelines for the transportation of sour hydrocarbon streams. The sulfur-containing fluids are mixed with an inorganic caustic material, an alkyl alcohol and an organo mercaptan or sulfide compound capable of reacting with sulfur to form a fluid-insoluble polysulfide salt reaction product at ambient reaction temperatures. The treated fluid is then contacted with an adsorbent or filtered to remove the insoluble salt leaving a product of very low residual sulfur content.
