The present invention provides a fertilizing device having a permeable package for fertilizer and a method for slowly releasing fertilizer by placing the fertilizing device in or onto the soil in the vicinity of the plants or the crops. The permeable package is enclosed with a layer for protecting the package and preventing unintended release of fertilizer from the permeable package.

The invention provides compositions comprising a polymeric carrier of cellulose and/or starch, and an element. The carrier is insoluble in water and a salt of the element is soluble or partially soluble in water. The compositions include at least about 5% (wt/wt) of the element, based on a total weight of the composition, and have particle sizes between about 0.05 mm and about 1.5 mm. Also provided are methods of making such compositions and methods for using the compositions to deliver the element to a plant.

In accordance with the present invention, disclosed herein is a fertilizer core and fertilizer granule and methods related thereto. The fertilizer core particle has an outer surface and comprising one or more fertilizer additives, one or more binders, and one or more pH buffering agents, and wherein the fertilizer core particle comprises from about 10 wt % to about 99 wt % of the one or more binders.

A material (such as potassium hydroxide or ammonia) capable of reacting with ambient carbon dioxide to produce fertilizer is placed in the path of ambient air movement. Desirably the material is associated with a fabric which in turn is associated with a vane of a vertical axis wind turbine, the turbine performing useful work as well as supporting the material which produces a fertilizer. A misting system controlled by a controller may automatically apply a water mist to the material if the humidity is below a predetermined level. The fabric with produced nitrogen and/or potassium fertilizer may be placed directly into contact with soil, or shredded first, or burned to produce energy and an ash (and the ash applied to the soil). The wind turbine may have a convenient, versatile mounting system with three adjustable legs supporting a central component, and the spokes of the wind turbine may be slotted for easy assembly with vanes.

A system for applying CO.sub.2 gas to improve Cannabis production. A multi-stage system is disclosed including upstream, midstream, and downstream stages or subsystems. The upstream subsystem receives and stores gas, particularly CO2 gas. The midstream subsystem is communicatively connected to the upstream subsystem and to the downstream subsystem. It monitors the environment of the downstream subsystem, determines when and how to apply gas to plants growing in the downstream system, acquires gas stored in the upstream subsystem, and distributes it to the downstream system. It also has various monitoring, command and control, management, and reporting features. The downstream subsystem includes one or more plant growth areas or plots, gas distribution means, such as gas conduits, tubes or lines from the midstream subsystem, and the high efficiency, adjustable gas applicator, and various sensing and monitoring devices communicatively connected to the midstream subsystem.

A compact comprising particles and an active agent selected from a pesticide, a herbicide, a plant nutrient, a fertilizer, an arthropod attractant such as a semiochemical, a semiochemical, a food or protein bait, and including mixtures of two or more thereof.

A self-contained hydroseeding packet that can be quickly loaded into a portable hydroseeder having seed, mulch and fertilizer in a predetermined ratio bound by a tacifier. The seed, mulch and fertilizer dissolve into a slurry when combined with water. Optionally, the packet can have a color to identify areas previously seeded. The seed, fertilizer, and mulch are bound by a water soluble binding agent and is biodegradable.

Disclosed is an agrochemical delivery unit comprising an impermeable cell which is a cell made of material that is impermeable to water; an agrochemical within the impermeable cell; and a wick comprising a hydrogel, said wick having a portion located within the impermeable cell and a portion located outside of the impermeable cell. Also disclosed is an agrochemical delivery unit comprising (a) a cell comprising two or more cell wall segments wherein at least one segment is impermeable to water and at least one segment is permeable to water; and (ii) an agrochemical within the cell. The invention provides methods of making and using the units.

An encapsulated fertilizer that is made up of a water-soluble film having a compartment containing a pre-selected amount of fertilizer granules. The fertilizer granules include at least three nutrients, including nitrogen, phosphorous and potassium and are selected to target specific types of plants. Each fertilizer granule has a low salt index and is in a stable, non-leachable form. For proper manufacture, each fertilizer granule have aspect ratios dissimilar to 1 and low Sieve Grading Number. The water-soluble film pod is able to dissolve rapidly when exposed to an amount of water at a temperature of above 35 degrees Fahrenheit.
