EPSO Combitop:

• is a quick acting foliar fertiliser containing the nutrients magnesium and sulphur as well as manganese and zinc, all in the water-soluble form.
• meets the increasing requirement of micronutrients.
• can be quickly and fully absorbed through the leaf and therefore acts immediately.
• prevents quickly and reliably magnesium, sulphur, manganese and zinc deficiencies in growing crops.
• is especially suitable to be used as a preventative application to avoid that deficiency situations occur, autumn application at beginning of tillering improves the winter har-diness of winter barely.
• is fully effective irrespectively of the soil pH due to the direct foliar absorption.
• allows a quick, targeted and accurate application of manganese and zinc in combination with magnesium and sulphur.
• has been especially designed to suit the micronutrient demand of cereals and manganese demanding leafy crops in ideal combination with magnesium and sulphur.
• Is allowed in organic farming according to EEC-regulation 2092/91, if nutrient demand exists.

Four important plant nutrients

• is essential for the yield and quality formation of plants.
• plays a primary role in the photosynthesis as a central atom in the chlorophyll (pigment needed for leaf greening).
• is necessary in the energy, protein and carbohydrate metabolism for the incorporation and storing of assimilates.
• deficiency occurs most commonly during the peak crop growing phase as well as in periods of extreme weather (coldness, drought) or alternatively where soil magnesium availability is limited.

Sulphur

• is a vital nutrient needed for the protein synthesis of the plants and improves therefore the N use efficiency.
• is absorbed preferably by the plants as sulphate (SO₄-ion) via the roots as well as the leaves.
• gains increasingly in importance as the atmospheric sulphur deposition has clearly been reduced due to air pollution control measures.

Manganese

• activates various enzymes and is therefore in many ways relevant for the plants’ metabolism.
• is needed for the chlorophyll and photosynthesis as well as for the nitrate reduction and amino acid formation.
• improves the disease resistance of plants.
• is less available with increasing soil pH. The manganese fixation is aggravated in situations of droughts and intensive soil aeration. Therefore foliar application is effective and safe.

Zinc

• is an indispensable nutrient for protein formation, which is drastically inhibited if the nutrient is insufficiently supplied.
• is important for the stability of the ribosomes required for the formation of polypeptides from free amino acids.
• is needed for the extension growth of plant cells.
• deficiency manifests in stunted growth (dwarf plants), small leaves and leaf rosette formation. Wheat shows typical yellow-white spots, which gradually change into strips along the whole leaf.
