Onion fertilization recommendations

Onion has a shallow root system with less penetrating power and requires sufficient amounts of easily accessible nutrients in its zone

Successful onion production requires increased nutrient requirements. Considering that the root system is shallow and is mostly located in a layer of up to 20 cm, it is precisely there that sufficient amounts of easily accessible nutrients should be provided.

The introduction of mineral nutrients, i.e. fertilization, should be adapted to the agrochemical analysis of the soil, the planned yield, the sort, but also the method of production.

In the production of onions, in addition to nitrogen (N), phosphorus (P) and potassium (K), sulfur (S) is of great importance, which participates in the structure of proteins, enzymes, vitamins, aromatic substances, affects the content of dry matter and sugar, and the final quality and yield of the bulbs. Sulfur (S) in synergy with potassium (K) affects the increase of plant tolerance to stressful and unfavorable conditions of the external environment.

An excellent source of key and easily accessible macro and microelements are the formulations from the Elixir Zorka latest Supreme product line. Quick availability and easy accessibility of all nutrients from these formulations and potassium (K) in sulfate form (SOP) enable high, quality and stable yields to be achieved.

Which mineral fertilizer do we recommend for the onion crop

The product NPK 6:12:24 + 6% S in terms of its ratio of nutrients represents a well-balanced formulation for achieving high and stable yields of all cultivated plants that have an increased need for potassium (K)

AmoSulfan belongs to the category of nitrogen fertilizers. It is extremely suitable for feeding all types of plants. The use of AmoSulfan significantly improves the availability and uptake of phosphorus on alkaline and neutral soils

NutriVeg NPK 10:10:20 +2% MgO +9% S +0.2% B +0.1% Zn is a complex, solid mineral fertilizer, the application of which provides complete nutrition to cultivated plants with all necessary macro and microelements during the production process cycle

The product NPK 12:11:18 + 2% MgO + 15% S + 0.01% B + 0.02% Zn + TE is a complex, solid mineral fertilizer of superior quality, which is primarily used for the production of highly profitable fruit and vegetable crops

The product NPK 12:12:17+ 2% Mg + 14% S + 0.02% B + 0.01% Zn provides balanced nutrition for a large number of plant species. Carefully selected secondary macro and microelements ensure high yields and exceptional product quality

NutriBOOST NP 10:45 + 5% S + 1% Zn is a new generation microgranulated fertilizer with a special additive that protects phosphorus (P) from blocking in the soil, preventing its reaction with other elements such as Ca, Al and Fe

Spring fertilization of onions implies the use of nitrogen fertilizers, because nitrogen is the carrier of onion yield

Proizvodi Elixir Group

Amosulfan 20% N + 24% S

AmoSulfan contains nitrogen in ammoniacal form.

This form of nitrogen binds more easily and is more difficult to wash out from the soil profile, which makes it available to plants for a longer period of time. Sulfur, as the main macroelement, directly affects the increase in the quality of cereal grains, because it participates in protein synthesis.
