  • Patent number: 8685706
    Abstract: The present invention relates to a process for restoring disturbed arid land soil crust. According to the process, site-sourced biological soil crusts (BSC) serve as sources for liquid suspension inoculants onto degraded arid lands. The BSC are gathered from near the disturbed site, and organisms from them are cultured, replicated and multiplied many times, preferably off-site. Then, this inoculant resulting from the indigenous population is distributed live and active in a liquid suspension over the entire area of the disturbed site.

    Abstract: Surfactant compounds which include an amine ended polyalkylene glycol hydrophile linked to C22 to C60 mainly hydrocarbyl, particularly composite hydrocarbyl, especially derived from a polymerised fatty acid and/or an aralkyl substituted phenol, hydrophobe, are useful in dispersing solids, particularly active agrochemicals, in aqueous media, or as adjuvants in agrochemical formulations, particularly of water soluble non-selective herbicides. In particular the hydrophobe is derived from polymerised fatty acids, such as dimer and, especially, trimer acids or from aralkyl substituted phenols. Aqueous dispersions using such surfactants can remain stable even with substantial concentrations of electrolyte e.g. in stable agrochemical dispersions including water soluble electrolyte agrochemical, such as glyphosate and/or ammonium sulphate.

  • Patent number: 6889471
    Abstract: A stable aqueous suspension of water-soluble polyacrylamide particles is in a saturated solution of an ammonium salt. The polyacrylamide particles are characterized by a particle size of about ?150 mesh, and preferably ?270 mesh, with ?400 mesh most preferred. The suspension is at least about 2.5% by weight polyacrylamide. When the ammonium salt is ammonium sulfate, PAM concentrations as high as about 15% by weight can be achieved while still being easily flowable. The suspension is made by stirring the small particle PAM into the saturated ammonium salt solution. The PAM can be quickly dissolved to form a less concentrated PAM solution by adding the suspension to water or to a dilute solution, which can include calcium salts or other soil enhancers.
