A nitrogen-enriched water generator includes an elongated housing defining a sealed nitrogen/oxygen chamber in which nitrogen molecules are combined with oxygen molecules to form a nitrate (NO.sub.3) or a nitrite (NO.sub.2) gas (NOx gas). The housing includes an NOx gas and water mixing tube, a plasma generator and a nitrogen-enriched water trap. A water spray nozzle sprays water into the chamber. At least one air injection port injects air into the chamber. A vacuum port removes a volume of NOx gas not absorbed by the water from the sealed nitrogen/oxygen chamber.

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 of extending a period of increased soil nitrogen levels in a soil are described. The methods include applying a soil enhancement agent to the soil, where the soil enhancement agent may include one or both of (i) lactobionic acid, and (ii) a least one salt of lactobionic acid. The methods also include applying a nitrogen-containing fertilizer to the soil. The soil treated with both the soil enhancement agent and the nitrogen-containing fertilizer has a higher level of soil nitrogen for at least a portion of a grown cycle of a crop planted in the soil than the same soil treated without the soil enhancement agent during the growing cycle of the crop.
