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.

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 present invention relates to a method for utilizing fine-particle peat, in particular to a method for improving the stability of planting substrates.

Dry compositions for conditioning soil are provided that enhance plant growth by creating beneficial soil environments. The dry compositions include a superabsorbent polymer and a cellulosic fiber that includes at least one of hydroxyethylcellulose and methyl cellulose. In addition, methods are provided for improving soil condition by applying the compositions to soil. The compositions have improved handling properties, including flowability in commercial applications, relative to superabsorbent polymers alone. Surprisingly, the compositions can improve soil moisture retention, increase the uptake of nutrients by plants, reduce leaching of nutrients, pesticides, and microbes, and improve seedling ability to break through soil crusts as well or better than superabsorbent polymers alone.

The present subject matter is directed to a growing medium and method of use. The growing medium comprises coconut coir. The coconut coir has a specific range of electrolytes, particularly sodium, potassium, and calcium. The values of these elements is confirmed in the coconut coir through qualitative and quantitative measurements, such as photoelectric flame photometry, spectroscopy, or inductively coupled plasma atomic emission spectroscopy.
