Embodiments of the present invention include a green roof system that includes a tray or array of trays designed to work in a drip irrigation system. The tray frame preferably has an open bottom covered by a filter fabric.

An irrigation system comprises one or more waterlines coupled to one or more watering mechanisms for watering one or more areas. The watering mechanisms are fixed in place at the desired area by an adapter which removably couples the one or more watering systems in place. Water is supplied to each of the one or more watering mechanisms by traveling from the one or more waterlines and through one or more pressure compensators. The one or more pressure compensators regulate the water flow through the one or more watering mechanisms enabling the irrigation system to uniformly distribute water at a set and constant pressure value. The water is distributed by one or more valves which are used to control one or more zones of the irrigation system. In some embodiments, a controller controls the system based upon a signal received from one or more sensors of the system.

A plant watering device. The plant watering device includes an outer container having a plurality of apertures on a lower portion of a first sidewall, an inner container having a second sidewall defining and open upper end and an open lower end, wherein the second sidewall of the inner container is secured to an interior surface of the first sidewall of the outer container via a fastener; and an apron encircling an outer side of the first sidewall. The plant watering device is securable to the ground via a stake. In use, water is poured into the inner container, flows through the open lower end of the inner container to the outer container interior volume, and then exits the apertures of the outer container. This allows the water to gently diffuse around an area where a plant is planted, while the apron prevents soil erosion and damage to the plant.

A floating garden for individually potted plants, comprising a buoyant body with a plurality of through-bores extending from the top to the bottom surfaces, the through-bores adapted to receive potted plants and potting soil. Each through-bore comprises a larger diameter upper portion and a smaller diameter lower portion aligned with each other, and a netting cup in the lower portion extending adjacent the bottom surface of the buoyant body. The netting cup holds a wicking material such as peat moss in the lower portion of the through-bore, while the upper portion of the through-bore holds potting soil and the plant.

A method for forecasting an agricultural irrigation water requirement includes: selecting a baseline period and crops each with a sown area larger than a set proportion as typical crops; calculating an irrigation water quota of the typical crop during a growth stage according to meteorological information; obtaining ten-day rainfall in a water-saving area from weather stations; and calculating effective rainfall in a sown region of the typical crop based on the ten-day rainfall; calculating an irrigation water requirement per unit area of the typical crop; and determining whether the irrigation water requirement per unit area of at least one typical crop is greater than an average of actual irrigation water usage per unit area measured in consecutive years, if yes, correcting the irrigation water requirement per unit area of all typical crops according to actual irrigation water usage; otherwise calculating a total water requirement for a next year.

A sprinkler valve box has a housing, the housing having a base and sidewalls with a sealable lid thereon. The sidewalls may have one or more connecting ports therethrough. The housing has one or more pre-configured valves therein. The valves may be coupled to the one or more connecting ports in the sidewalls. The sidewalls are ideally corrugated for added strength and the lid seats over the sidewalls of the valve box, which may be lockable. The sprinkler valve box may also have a battery and a control unit, wherein the control unit is powered by the battery and controls the valves of the manifold. The control unit may be controlled wirelessly by a user.

A combined power conversion and carbon capture and recycling subsystem including a fossil fueled oxidation unit, a physical adsorbent CO2 capture medium, rotor, motor, heater, CO2 compressor, diffuser and water storage tank. Exhaust gas from fossil fuel oxidation is scrubbed of CO2 via passage across a physical adsorbent and then released from the adsorbent via fuel oxidation waste heat. High CO2 concentration scrubber exhaust air is then compressed and fed to a diffuser which facilitates dissociation of the CO2 into water where it is temporarily stored for use in watering plants. Carbon from fossil fuel is recycled back into the environment and permanently stored as biomass by natural means of photosynthesis.
