Fertilizers

Ammonium free calcium nitrate

Calcium improves the rigidity of the cell walls and is a building block for cell membranes. Every plant needs calcium for healthy growth.
Fertilizers

Calcium nitrate

Calcium nitrate is a source of calcium for use in fertilizer solutions in the agricultural and (greenhouse) horticultural sector.
Fertilizers

Coated fertilizers

Our Sustainable Fertilizer Additives Improve the Quality and Stability of your crops. High Quality Fertilizers. Competitive Pricing.
Fertilizers

EPSOM salt

Magnesium nitrate is a source of magnesium to be applied in fertilizer solutions in the agricultural and (greenhouse) horticultural sector.
Fertilizers

Kalisalpeter potassium nitrate

Potassium Nitrate is a source of nitrogen and potassium for use in fertilizer solutions in the agricultural and horticultural sectors.
Fertilizers

Magnesium nitrate

Magnesium is an important source for the production of chlorophyll. Magnesium an element for the production of chlorophyll & enzymes.
Fertilizers

Magnesium nitrate

A highly water soluble Magnesium Nitrate that can be applied as foliar feeding or through irrigation systems.
Fertilizers

MKP

MKP is a source of phosphates and potassium for use in fertilizer solutions in the agricultural and horticultural sector.
Fertilizers

Siligood

Siligood is a leaf fertilizer containing at least 3% silica, which strengthens the cell walls, the epidermis and facilitates a better distribution of Ca and Mn.

Fertilizers

Fertilizers are fundamental to crops in order to produce enough harvest for the rising global demand. Fertilizers provide crops with vital nutrients like phosphorus, potassium, and nitrogen, which help support the crops grow bigger, faster, and ultimately harvest more production.

Benefits of using Fertilizers

  • Increases crop yield and improves land quality
  • Provides multiple crop yields a year
  • Supply of plants with everything they need
  • Improves soil texture and introduces essential bacteria
  • More stable and predictable yields
  • Plants better protect against pests
  • Efficient usage of farming space
  • Less waste

Our Chelates Assortment

Our product range of chelated fertilizers includes Iron chelate, Manganese chelate, Zinc chelate and Copper chelate elements. Depending on the chelate Stable pH percentage, we can offer the most common chelates used in agriculture – EDTA, DTPA, EDDHA and HEEDTA.

Fertilizers & trace minerals

Copper chelate Cu EDTA 15%

This is a copper chelate, which you can use for the input of the trace element copper (Cu). Copper is of big importance for the process of photosynthesis.
Fertilizers & trace minerals

DTPA 6% chelate

The most used liquid DTPA chelates are 3% and 6%. The 3% version is based on sodium and the 6% is based on ammonium.
Fertilizers & trace minerals

EDDHA 6% chelate

It is recommended to add EDDHA or completely replace your iron chelates with EDDHA (red iron) when the pH value is equal or greather than 6,5.
Fertilizers & trace minerals

FE EDTA

It is used by the plant for the formation of chlorophyll and therefore important for the photosynthesis. Contact us for more information.
Fertilizers & trace minerals

HEEDTA chelate

There is a different chelating factor in pH target stability and light sensitivity. Trace element Chelate former pH target Stability:
Fertilizers & trace minerals

Manganese chelate Mn EDTA 13%

Chelated trace elements are more effective because the chelating molecules protect trace elements against insolubility.
Fertilizers & trace minerals

Zinc fertilizer Zn EDTA 15%

Zn EDTA is a 15% zinc (Zn) fertilizer, the element zinc is bound to an EDTA chelate. This makes it better to absorb for the plant.
