Nutrient compositions for plant growth are disclosed. A nutrient composition includes primary macronutrients, including nitrogen, phosphorus, and potassium, secondary macronutrients including calcium and sulfur. A nutrient composition may include micronutrients and additional secondary macronutrients, such as magnesium. Nutrient compositions including such nutrient sources exhibit advantageous plant growth. Hydroponic nutrient composition, water soluble powder, and plant growth mediums containing the nutrient composition, as well as methods of using the nutrient compositions, are further disclosed.

The present disclosure provides a seeding formulation for woody plants and a pre-treatment of surfaces (e.g. rocks, waste rocks, tailings, overburden) on disturbed and degraded lands. The seeding formulation includes a mix of woody trees or shrubs seeds, organic mulch, beneficial microbial populations, mineral fertilizer, adhesive, absorbent polymer, and water. The pre-treatment of surfaces refers to the spreading or mixing of surfaces with organic biomass. Methods of preparing and applying the seeding formulation and pre-treatment are also disclosed. The formulation is used for the phytoremediation, ecological restoration, land reclamation, environmental rehabilitation, revitalization, revegetation, and reforestation of disturbed and degraded lands.

Methods for promoting plant growth based on novel photosafening treatment regimes with glycopyranosides including glycopyranosylglycopyranosides, and aryl--D-glycopyranosides, and more specifically, with one or more compounds comprising terminal mannosyl-triose, optionally in the presence of light enhanced by one or more light reflecting and/or refracting members such as silicon-based substrates. Furthermore, chemical synthesis processes for the above compounds are disclosed for general application to plants. Silicate microbeads of the like are distributed over the ground or substrate in which roots of a plant are supported and planted, beneath and around a plant in a manner that light is refracted or reflected toward the phylloplane.

The element is intended to be placed in a receptacle for the cultivation of at least one plant, and includes:

a substantially solid body including a substrate adapted to enable said plant to develop;

at least one seed of said plant disposed on the body in at least one seed receiving area;

a layer for holding the seed(s) in said receiving area, comprising a dried mineral powder.

The holding layer results from drying a deposition of a holding composition including a mineral powder suspended in water.

An apparatus for treating water in soil-less growing systems has a container having a cross-sectional area and a height, with a first access port for liquid at an upper end, and a second access port for liquid at a lower end, and a porous matrix filling the container, the matrix comprising a hydrophilic polymer mixed with rocks and natural minerals. Water drawn from a soil-less growing system, is urged into the container through one of the liquid access ports, causes the water to flow through the matrix in the container, the water in contact with the rocks and natural minerals in the matrix, leaching elements from the matrix, and causes the water to exit the container at the other of the liquid access ports, to flow back to the soil-less growing system.

A structure has a high-impact plastic polymer tile comprising interconnected individual cells, each having an outer wall of a vertical dimension forming a closed outer periphery, and a matrix filling the cells from a lowermost extremity of the walls of the cells, to level below an uppermost extremity of the internal walls of the cells, the matrix comprising material supporting plant growth. With the tile lying on a base surface, the individual cells of the tile constrain the matrix material from horizontal translation, and wherein the walls of the cells, extending above the level of the matrix in the cells, provide support for any wheeled vehicle without disturbing the matrix.

An article that supports germinating seeds and growing plants is provided and disclosed. The article includes a substrate with openings therethrough for developing plants. The substrate includes a phosphor containing layer on the closed substrate surfaces and optionally a reflective layer below the phosphor containing layer on the closed surfaces. The substrate with openings and phosphor containing layer on closed surfaces of the substrate can be disposed over a growth medium. The article having the phosphor containing layer is configured to convert at least a portion of incident plant growth light into longer wavelength red spectrum containing light, and redirect the red light to the developing plants.
