FERTILIZER PACKAGE
KertMix
Mix your own fertilizer blend with macro-, meso-, and microelements
With the KertMix package, we’re putting an intensive plant nutrition technology in your hands—one that professional nurseries have been using for a long time. We know that the moment-to-moment nutrient needs of our cultivated plants are constantly changing, depending on variety, stage of development, weather, and countless other factors. In professional horticulture, this is simplified by continuously adjusting the composition and quantity of the nutrient solution and irrigation water to match the specific phenology—or growth stage—of the cultivated plant. Based on a program developed by an agricultural consultant, they add the necessary macronutrients (N, P, K), mesonutrients (Mg, S, Ca), and micronutrients (Fe, Mn, Zn, Mo, Cu, B) to the irrigation water.
In home gardens and small-scale commercial production, however, we use pre-manufactured “one-size-fits-all” complex fertilizers, which cannot even come close to meeting the constantly changing needs of a garden’s diverse plants. Undernourished plants grow poorly and produce low-quality crops. Over-fertilization pollutes our groundwater and destroys soil biodiversity. Well-developed, healthy, and resilient plants can only be grown with optimal plant nutrition.
We’ve adapted the professional method mentioned above for home gardening so that you don’t have to buy a wide variety of complex fertilizers. Using the components of our KertMix package and following the instructions, you can prepare the fertilizer mixture with the exact composition and quantity your plants need at any given time—whether for foliar feeding, irrigation, or the increasingly popular and economical drip irrigation method.
The KertMix package contains enough nutrients for a 100 m² garden for the entire season when applied on a weekly basis.
