NPK refers to the three primary macronutrients that are essential for plant growth: nitrogen (N), phosphorus (P), and potassium (K). These nutrients are typically found in fertilizers and soil amendments used to improve plant growth and crop yields.

The nitrogen in NPK fertilizers promotes leafy growth and green color in plants, while phosphorus supports root and flower development, and potassium helps plants to resist disease and stress.

When choosing a fertilizer, the NPK ratio on the packaging will indicate the percentage of each nutrient in the product. For example, a fertilizer with an NPK ratio of 10-10-10 contains 10% nitrogen, 10% phosphorus, and 10% potassium by weight.

NPK nutrient solutions are being used for hydroponics, aeroponics, and conventional soil farming.

Depending on its composition and the type of crops, an NPK formula might need to be supplemented with nutrient boosters featuring micronutrients (iron, zinc, manganese, copper, boron, molybdenum etc.).

NPK nutrient solutions are being used for hydroponics, aeroponics, and conventional soil farming.

When choosing an NPK mix, it is crucial to stay away from man-made synthetic ingredients and to only choose the purest form of naturally extracted minerals.

At Agrotonomy Tower Farm, we prefer to use the NPK formula manufactured by Tower Farms/Tower Garden which is the soluble ironic mineral 100% natural mineral solution.
However, many types of nutrients can work with our aeroponic tower technology. In fact, some of our clients are using their own NPK formula, some others prefer to use nutrient-enriched water for their aquaponic farms, others are using organic nutrients suitable for hydroponics, etc.

Our tower technology is extremely versatile and although many types of nutrients can be used, after all the comparative tests that we have run over the years with Tower Garden technology, we have definitely concluded that once again, the nutrients manufactured the ironic solution is by far the most versatile and the best in terms of crop yield. It has been engineered for the highly oxygenated environment at the root level of the plants which allows an increase nutrient absorption at the root level.
