El Primero Garden Fertilizer

El Primero is distributed by Alpha One, a bulk fertilizer supplier that makes dog-safe fertilizers for plants, gardens, and lawns containing a homogenous nutrient balance that distributes the plant-ready nutrients in a natural time-release, so the plants have extended access to them. Only the highest quality and the safest materials are used to make El Primero. The exact measurement of its components guarantees the consistency of its performance, and the formulation creates a uniform flower-to-foliage ratio without the typical ‘lush growth syndrome’ that commonly follows the application of chemical fertilizers. The organic-based amino acids of El Primero counter high pH (alkaline) calcareous soils to create a better soil quality for all varieties of garden plants. Alpha One is a bulk fertilizer supplier that makes dog-safe fertilizers for plants and lawns.

El Primero contains no manures, sludge, or waste materials.
