Introduction WebJun 25, 2024 · Literally, the word qi means "breath," 'air" or "gas, but figuratively, qi is life-force—that which animates the forms of the world. It is the vibratory nature of phenomena—the flow and tremoring that is happening continuously at molecular, atomic and sub-atomic levels. WebNitrogen should be applied in split applications. As an extra precaution to maintain low levels of NPN in cool-season grasses, maintain ample levels of phosphorus and potassium in the soil. Potassium serves a catalytic function in protein synthesis thereby lowering the level of NPN and phosphorus is important in energy metabolism (ATP). tsion yacob
