Glossary

Occurs naturally when roots are exposed to air in the absence of high humidity. The roots are effectively “burned” off, causing the plant to constantly produce new and healthy branching roots.

A plant, Medicago sativa, of the legume family, usually having bluish-purple flowers, originating in the Near East and widely cultivated as a forage crop.

Any invertebrate of the phylum Arthropoda, having a segmented body, jointed limbs, and usually a chitinous shell that undergoes moltings, including the insects, spiders and other arachnids, crustaceans, and myriapods.

Ubiquitous one-celled organisms, spherical, spiral, or rod-shaped and appearing singularly or in chains, comprising the Schizomycota, a phylum of the kingdom Monera (in some classification systems the plant class Schizomycetes), various species of which are involved in fermentation, putrefaction, infectious diseases, or nitrogen fixation.

(relating to ecology) the amount of living matter in a given habitat, expressed either as the weight of organisms per unit area or as the volume of organisms per unit volume of habitat

A nitrogen-containing polysaccharide, related chemically to cellulose, that forms a semitransparent horny substance and is a principal constituent of the exoskeleton, or outer covering, of insects, crustaceans, and arachnids.

Any of numerous microscopic, unicellular, marine or freshwater algae of the phylum Chrysophyta, having cell walls containing silica.

In botany, the flowering stage refers to the phase where plants produce their flower sets, vegetables, and fruits.

Crops grown specifically to be grazed by livestock or conserved as hay or silage.

Any of a diverse group of eukaryotic single-celled or multinucleate organisms that live by decomposing and absorbing the organic material in which they grow, comprising the mushrooms, molds, mildews, smuts, rusts, and yeasts, and classified in the kingdom Fungi or, in some classification systems, in the division Fungi (Thallophyta) of the kingdom Plantae.

Insect poop (like guano or castings), but unlike bats or birds, Insect frass actually comes from plants. In all natural ecosystems (where there are no man-made chemical pesticides), insects feed on and digest vegetation, and give it right back to plants in the form of nature’s perfect plant food.

A microorganism, especially a pathogenic bacterium.

Any organism too small to be viewed by the unaided eye, as bacteria, protozoa, and some fungi and algae.

A thick syrup produced during the refining of sugar or from sorghum, varying from light to dark brown in colour.

A covering, as of grass, bark, compost, or plastic sheeting, spread on the ground around plants to prevent excessive evaporation or erosion, enrich the soil, inhibit weed growth, etc.

A symbiotic association of the mycelium of a fungus, especially a basidiomycete, with the roots of certain plants, in which the hyphae form a closely woven mass around the rootlets or penetrate the cells of the root.

Any unsegmented worm of the phylum Nematoda, having an elongated, cylindrical body.

The chemical processes by which atmospheric nitrogen is assimilated into organic compounds, especially by certain microorganisms as part of the nitrogen cycle.

A plant which takes up the available nitrogen within the soil into its cell walls. This is returned to the soil when the crop is harvested and turned back into the soil. These crops also retain the soil deterring nutrient loss through water runoff.

An agricultural technique of growing crops or pasture without disturbing the soil through tillage or turning.

An insect or other small animal that harms or destroys garden plants, trees, etc.

A process of decontaminating soil or water by using plants and trees to absorb or break down pollutants.

Readily available for the plant to uptake. This refers to broken down matter which has degraded down to the state that the plant can receive it.

A major grouping or superphylum of the kingdom Protista, comprising the protozoans.

Any of a diverse group of eukaryotes, of the kingdom Protista, that are primarily unicellular, existing singly or aggregating into colonies, are usually nonphotosynthetic, and are often classified further into phyla according to their capacity for and means of motility, as by pseudopods, flagella, or cilia.

A 6-panel cap with a wide flat brim. Snapbacks are fitted with an adjustable snap on the back of the cap consisting of two pieces of plastic that snap together, which makes it ‘one size fits all’.

Refers to the phase of plant growth that occurs after germination and before flowering, during which the plant develops the majority of its foliage and truly flourishes.

The raising and production of earthworms and their by-products.

The botanical component of pest control, which attempts to stop weeds, especially noxious weeds, from competing with desired plant life.

A convoluted mass of soil, mud, or sand thrown up by an earthworm or lugworm on the surface after passing through the worm’s body. Worm Castings contain a highly active biological mixture of bacteria, enzymes, remnants of plant matter and animal manure, as well as earthworm cocoons (while damp). The castings are rich in water-soluble plant nutrients, and contain more than 50% more humus than what is normally found in topsoil.
