SKU 26613-cMikrochelat Cu-15 (15%) Intermag - copper fertiliser
Mikrochelat Cu-15 Intermag is a fertiliser containing fully chelated copper (150 g Cu/kg, i.e. 15%) by EDTA, which enables rapid absorption, translocation and uptake of copper by plants.
Description
Mikrochelat Cu-15 Intermag - the most effective source of copper for your plants
Mikrochelat Cu-15 is a fertiliser containing copper. The copper contained in the fertiliser is fully chelated by EDTA (150 g Cu/kg (15%)). Copper (Cu) prepared in this way is absorbed, translocated and taken up by plants faster compared to copper supplied to plants in other forms.
Mikrochelat Cu15 Intermag can be used prophylactically and interventively:
Used preventively in crops with high copper requirements (e.g. cereals, onion, carrot, sugar beet, lettuce, spinach) it will be the most effective source of copper. It becomes essential in the presence of soil conditions limiting the availability of this nutrient to plants. Such conditions include high pH, high organic matter content, high permeability coefficient, especially in crops on soils recently brought into agricultural use and rich in humus – the so-called "new land disease". Used at timings and doses recommended in fertilisation programmes for specific species, it effectively prevents copper deficiency in plants.
During interventive use it effectively eliminates copper deficiency and reduces the negative effects of such temporary deficiency. Plants should be fed interventively when visual symptoms of copper deficiency appear on plants or when plant tissue analysis results indicate too low copper content (hidden deficiencies).
Copper (Cu) supplied to plants in Mikrochelat Cu-15 fertiliser is:
- efficiently and rapidly taken up by plants from solutions in foliar feeding, in fertilisation treatments with irrigation (fertigation) and from soil after soil fertilisation,
- safe for plants in all application techniques (according to recommended doses),
- stable in multi-nutrient solutions used in foliar treatments, fertigation and soil sprays,
- stable over a wide pH range of solutions/media,
- stable in soils over a wide pH range.
Copper (Cu) supplied in Mikrochelat Cu-15 Intermag fertiliser positively affects yield quantity and quality, including:
- Ensures proper development of young plant parts, their subsequent growth and fruit ripening,
- Ensures proper development of vascular tissue – effective transport of nutrients and water in plants,
- Increases mechanical strength of plants (e.g. greater lodging resistance of cereals),
- Guarantees efficient nitrogen utilisation,
- Intensifies biomass growth and ensures better quality parameters of the yield,
- Improves plant health during cultivation and storage.
Mikrochelat Cu-15 is intended for use in various fertilisation techniques:
- foliar feeding,
- fertigation (in inert, organic substrates, in soil),
- soil spraying/watering or top dressing after mixing with other soil fertilisers.
Other uses of Mikrochelat Cu 15:
Mikrochelat Cu-15 can also be used as a component of dry and liquid fertiliser mixtures. We also recommend it as a copper source for other chemicals.
Composition of Mikrochelat Cu-15 Intermag:
- Content of copper (Cu) chelated by EDTA: 150 g Cu/kg (15%).
Mikrochelat Cu15 is distinguished by very good user properties:
- it is quickly and completely soluble (also in cold and hard water), thanks to the unique ultragranul structure. The solution formed after dissolving ultragranul is free of sediment,
- does not dust,
- does not cake - high resistance to external factors during storage.
Physicochemical properties of Mikrochelat Cu 15 chelate solutions:
- product stable in pH range 2–10,
- high solubility in demineralised water – 1000 g/dm3,
- EC in demineralised water: 0.1% solution – 0.4 mS/cm,
- pH in demineralised water: 0.1% solution – 5.6.
How to use Mikrochelat Cu-15?
FERTIGATION (fertilisation with irrigation) of crops in inert, organic substrates, in soil:
- Detailed recommendations (composition of the nutrient solution and frequency of application) should take into account the nutritional requirements of plants and the agrotechnical and climatic conditions of the cultivation (including substrate type).
- Calculations should consider copper (Cu) content in other fertilisers used to prepare the nutrient solution and in water used for preparation.
Fertigation in inert substrates and coconut substrate and hydroponic crops (nutrient solution supplied continuously or multiple times per day).
- The most commonly recommended copper (Cu) content in the ready-to-use nutrient solution is 0.1–0.3 mg Cu/l (i.e. 0.7–2 g MIKROCHELAT Cu-15 per 1000 l).
- When preparing concentrated solutions, the MIKROCHELAT Cu-15 dose should be proportionally increased.
Fertigation in organic substrates and soil (nutrient solution supplied periodically - multiple times during the growing season). When using MIKROCHELAT Cu-15 with other fertilisers in the ready-to-use nutrient solution, do not exceed a total concentration of 0.2% of all components (i.e. 2 kg and/or l per 1000 l nutrient solution). Recommended amount of MIKROCHELAT Cu-15 during the whole growing season (in split doses, max. 0.5 kg/ha per cycle):
- 1–3 kg/ha (agricultural crops sprinkling: cereals, soybean and other legumes, oilseed rape, maize, sunflower, potato)
- 2–4 kg/ha (pome and stone fruit trees, nuts, grapevine)
- 1–3 kg/ha (fruit bushes, strawberry)
- 0.5–1.5 kg/ha (vegetables)
- 0.5–0.8 kg/ha (ornamental plants).
SOIL SPRAY/WATERING or TOP DRESSING after mixing with other soil fertilisers:
- Spray the soil with solution before sowing or planting seedlings, or use together with other soil fertilisers.
- Recommended amount of MIKROCHELAT Cu-15 during the whole growing season: 2–3 kg/ha.
FOLIAR FEEDING (LEAF SPRAY):
- In foliar feeding treatments use MIKROCHELAT Cu-15 in aqueous solution. The fertiliser can be used together with other preparations after performing a compatibility test.
- We recommend caution in selecting the number of treatments to avoid exceeding the copper dose safe for plants.
Interventively - use MIKROCHELAT Cu-15 when visual symptoms of copper deficiency appear on plants or after diagnosing too low copper content in plants. Perform treatments every 3-7 days until deficiency disappears. For more than one treatment use MIKROCHELAT Cu-15 at doses:
- agricultural crops, fruit bushes, strawberry: 0.2–1 kg/ha
- fruit trees, grapevine: 0.5–1 kg/ha
- vegetables, ornamental plants: 0.1–0.5 kg/ha.
Prophylactically - use MIKROCHELAT Cu-15 at timings and doses shown in the table below.
Doses can be modified considering individual plant needs and cultivation conditions. At low air humidity avoid using solutions with concentration exceeding 0.15% (1.5 kg fertiliser/1000 l water). When applying foliar feeding in protected cultivation do not exceed 0.15% concentration.
Doses can be modified considering individual plant needs and cultivation conditions. In fruit tree sprays and at low air humidity avoid using solutions with concentration exceeding 0.1% (1 kg fertiliser/1000 l water) to avoid risk of permanent leaf damage. When applying foliar feeding in protected cultivation do not exceed 0.1% concentration.
