Abstract: A system for delivering fertilizer to the roots of a plant includes coated fertilizer particles. The coating can include a cellulose derivative, optionally a fatty acid, and a component, such as an aptamer, which binds specifically to a material, such as serine, which is released by the roots of the plant when the plant is actively taking up nutrients from the soil. The permeability of the coating increases when the coated particles are exposed to the material released by the roots of the plant. Thus, nutrient release from the coated fertilizer particles is synchronized with uptake of the nutrients by the plant during active growth. Advantages of the system may include one or more of improved nitrogen use efficiency by the plant, improved crop productivity, and/or reduced leaching of fertilizer from the soil.

Abstract: The invention features a two-piece holder which features an expandable opening sized to receive and support numerous size cigars. The opening features ridge cuts that aid in holding a cigar in its desired position. The handle of the holder affords the user the opportunity to smoke the body of the cigar to the fullest possible extent without burning the smoker's fingers.
