Epsom salts / sulphate of potash

Patentkali is a mineral multi-nutrient fertilizer that primarily supplies potassium and also contains magnesium and sulfur. In Living Soil, it is particularly interesting when a soil needs to be specifically supplied with potassium without using chloride-containing potassium fertilizers. This is precisely why Patentkali is used by many growers when the bloom needs more boost, the plant is not performing well despite good basic nutrition, or when a reused soil needs to be topped up with potassium, magnesium, and sulfur.

Patentkali is particularly relevant during the flowering phase. Potassium plays a central role in water balance, cell turgor, enzyme activity, metabolism, and the general performance of the plant. If potassium becomes too scarce, weaker growth, reduced flower development, poorer turgor, or generally less stable plant performance often become apparent. Since Patentkali also provides magnesium and sulfur, the raw material is also interesting when not only potassium, but several nutrient axes appear slightly undersupplied.

However, in Living Soil, Patentkali is not a classic basic raw material like compost, worm castings, or mild organic nitrogen sources. Patentkali is more concentrated, mineral, and salt-heavy. This is precisely why it is particularly suitable as a targeted correction, as a supplement for reconditioned soil, or as a deliberately used bloom input. In small pots, with young plants, or in already heavily loaded mixtures, it should be used cautiously, because too much Patentkali can quickly lead to an unnecessarily harsh setup.

Patentkali is often synonymously associated with Kalimagnesia or potassium sulfate-based potassium-magnesium fertilizers. For growers, Patentkali is primarily the raw material when potassium, magnesium, and sulfur are to be supplemented in one step. In Living Soil, it remains a useful tool for targeted corrections, strong flowering phases, and the regeneration of depleted soil mixtures.
