    摘要: An agricultural fertigation method includes the in situ manufacture of one or more fertilizers within the irrigation upstream of the agricultural field being irrigated. Co-reactant raw materials, namely sulfuric acid, phosphoric acid, nitric acid, potassium hydroxide, urea, ammonium hydroxide, ammonia, calcium nitrate and/or magnesium nitrate, are intermixed with each other and with the stream of the flowing irrigation water. The stream of flowing irrigation water dampens the resultant dissolution and reaction exotherms. A system wherein raw materials are efficiently fed to the irrigation system main line or a side-arm reactor efficiently implements the method.

    摘要: A medium for enhancing growth and availability of water and nutrients during plant growth, comprising a synthetic resin and a support material, the resin consisting essentially of a substantially-linear, non-gelling, water-soluble polymer capable of forming a water absorbing network with the support material, such that the polymer is dispersed within the material upon exposure to water and retains and transports water and nutrients for seedling growth. Use of such polyacrylamides benefits growth by retaining water, reducing evaporation loss, improving yields and enhancing nutrient uptake.
