  • Patent number: 8584400
    Abstract: The invention provides processes for coating the surface of substrates such as a sheet, film, foam, fiber, etc., with a curable liquid resin or solution of curable resin, then in one embodiment, stably attaching a superabsorbent polymeric powder to such resin, and then curing the resin to form a coated superabsorbent product. Such substrates may include polymeric materials. Other process embodiments utilizing curable and thermoplastic resinous powders may be used instead of curable liquid resins and resulting products are included in the invention. Other embodiments involve affixing a container at least partially filled with superabsorbent polymeric powder to a substrate, placing the container proximate to the element, or affixing the container to a separate member. The products may be utilized for water and nutrient retention in combination with irrigation, erosion control, to direct plant root growth, and to clean up standing water and petroleum spills.

    Abstract: This invention is related to device, its production process and also to the usage of the trbe shaped device (1) filled with a liquid means (6) for the plats nutrition/protection, which is inserted into the substrate (8) as much as closer to the main plant, where discharge occurs. Novelty is reflected in the way of forming and removing the shutters now obtained by heating wax, resin, plastic, rubber, hot-melt glues and compounds of similar characteristics, upon whit they become a liquid mass in which the openings of the tube are to be immersed; in this way, the film, after being hardened, forms the membrane (3a, 3b) which, due to the pressure to the sides of the tube (1), out-breaks; unlike of classic shutters which makes production and usage more complicated and makes some waste after being used.

  • Publication number: 20130263502
    Abstract: A formulation for preparing a hydrogel for watering plants includes carboxymethyl cellulose and a dispersant. The dispersant disperses the carboxymethyl cellulose on addition of water thereby preventing formation of aggregates. The dispersant can be vermiculite, perlite, pectin, maltodextrin, guar gum, xanthan gum, or seaweed extract. A hydrogel for watering plants can be prepared by adding water to the formulation and mixing, and a method of forming the hydrogel is described. A pouch for watering plants contains the formulation and, when opened, water is added to form the hydrogel. A pot containing a plant in a plant-supporting matrix is placed in the pouch.

  • Patent number: 8533995
    Abstract: The automatic watering device for plants is placed in the soil of a potted plant. A float is housed in an outer chamber. The float has a ferrous metal contact at each end, with and the chamber has magnets at each end. The chamber top has a water inlet. The upper end of the float has a shutoff valve. The lower end of the chamber has a calibrated orifice for water dispensing. A water supply is connected to the chamber inlet. The water eventually provides sufficient buoyancy to the float to release it from its lower magnet and rise for attachment to the upper magnet, thereby shutting off the water inflow. Water continues to seep from the lower orifice until the level drops within the chamber to a point sufficient to cause the float to to drop from its upper magnet, allowing the water to again flow into the chamber.

  • Patent number: 8533992
    Abstract: A system and method of aeroponic farming includes depositing seeds in a flat containing micro-fleece cloth and placing the flat within a growth chamber. The upper side of the flat is subjected to light of the proper frequencies to promote growth in plants. A nutrient solution is sprayed onto the micro-fleece cloth and the developing root mass of the plants, while controlling temperature, humidity, and carbon dioxide within the growth chamber. The plants are harvested resulting from the seeds at a desired stage of growth. The growth chambers can be stacked on each other and/or located side by side to save space within a facility, and to permit sharing the subsystems which control the nutrient solution, temperature, humidity, and carbon dioxide for the growth chambers.

  • Patent number: 8528834
    Abstract: A system for automating the growing of crops, such as grapevines. Combinations of data from sensors local to a vineyard, and from optional remote stations and sensors, is combined with a control system to accurately control the dispensing of water and chemicals such as insecticides, disease prevention fungicides and fertilizers. The materials are dispensed through a multiple channel conduit which allows conflicting, or incompatible, types of materials to be transported through a common assembly. Sensors are attached to the conduit so that the placement of sensors can occur simultaneously with the laying of the conduit. This approach also ensures correct placement and spacing of the sensors with respect to each plant, or plant area, to be monitored and treated.
