SKU 35971-cMikrochelat Fe-13 (13%) Intermag - iron fertiliser
Mikrochelat Fe-13 Intermag is a fertiliser containing 130 g of iron (Fe) chelated by EDTA per kg (13%).
Description
Mikrochelat Fe-13 Intermag - the most effective source of iron for your plants
Mikrochelat Fe-13 is a fertiliser containing iron. Iron is fully chelated by EDTA (130 g Fe/kg (13%)). This form of iron (Fe) as a chelate is absorbed, transported and assimilated by plants faster compared to iron supplied to plants in other forms. Additionally, it is stable and safe for plants in all application techniques.
What are the benefits of using Mikrochelat Fe-13 Intermag?
Iron (Fe) supplied in the Mikrochelat Fe-13 fertiliser positively affects yield size and quality, including:
- increases chlorophyll formation intensity and stress resistance,
- increases biomass and supports proper plant growth and development,
- helps plants regenerate faster and achieve better quality parameters,
- improves overall plant condition,
- reduces the risk of excessive accumulation of nitrates and harmful nitrites in the yield.
Iron (Fe) supplied to plants in Mikrochelat Fe-13 fertiliser is:
- efficiently and rapidly taken up by plants from solutions in foliar feeding, in fertilisation with irrigation (fertigation), and from soil after soil fertilisation,
- safe for plants in all application techniques (if used according to recommended doses),
- stable in compound solutions (within pH range up to 7), used in foliar treatments, soil sprays and fertigation.
Mikrochelat Fe-13 Intermag can be used both preventively and interventively:
Used preventively in crops with high iron requirements (e.g. beans, sugar beet, cabbages, broccoli, cauliflower, spinach, tomato, sweet pepper, strawberry, acid-loving plants grown on neutral or alkaline soils) it will be the most effective source of iron. It becomes essential when soil conditions limit iron availability to plants. Such conditions include high pH, lack of oxygen in the root zone, and high iron content in plants.
Used interventively (at timings and doses recommended in fertilisation programmes for specific species) it effectively eliminates iron deficiency and limits the negative effects of such temporary deficiency. Plants should be fed interventively if visual symptoms of iron deficiency appear or if plant tissue analysis indicates too low iron content (hidden deficiencies).
Mikrochelat Fe-13 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.
Mikrochelat Fe-13 can also be used as:
Mikrochelat Fe-13 can also be used as a component of dry and liquid fertiliser mixtures. We also recommend it as a source of iron for other chemicals.
Composition of Mikrochelat Fe-13 Intermag:
- Content of iron (Fe) chelated by EDTA: 130 g Fe/kg (13%).
Very good user properties of Mikrochelat Fe-13:
- fast and complete solubility (also in cold and hard water), all thanks to the unique ultragranule structure. The solution formed after dissolving ultragranules is sediment-free,
- no dusting,
- no caking - high resistance to external factors during storage.
Physicochemical properties of Mikrochelat Fe-13 Intermag chelate solutions:
- product is stable in pH range 1–7,
- high solubility in demineralised water – approx. 300 g/dm3,
- EC in demineralised water: 0.1% solution – 0.42 mS/cm,
- pH in demineralised water: 0.1% solution – 8.1.
How to use Mikrochelat Fe-13?
FOLIAR TREATMENTS (LEAF SPRAY):
- In foliar feeding treatments, use Mikrochelat Fe-13 as an aqueous solution. The fertiliser can be used together with other products after conducting a compatibility test.
Interventively – use Mikrochelat Fe-13 when visual symptoms of iron deficiency appear on plants or after diagnosing too low iron content in plants, as well as in case of root system flooding.
Perform treatments every 3–5 days until deficiency symptoms disappear. Use Mikrochelat Fe-13 at doses:
- field crops, fruit trees, grapevine: 0.5–1 kg/ha
- fruit bushes, strawberry, vegetables, ornamental plants: 0.2–1 kg/ha.
Preventively – use Mikrochelat Fe-13 at timings and doses presented in the "Dosage" tab.
FERTIGATION (fertilisation with irrigation) of crops in inert, organic substrates, in soil:
- Detailed recommendations (nutrient solution composition and application frequency) should consider plant nutritional requirements and agrotechnical and climatic conditions of the crop (including substrate type).
- Calculations must take into account iron (Fe) content in other fertilisers used to prepare the nutrient solution and in the water used.
- Fertigation in inert substrates and coconut substrate and hydroponic crops (nutrient solution supplied continuously or multiple times daily).
- The most commonly recommended iron (Fe) content in ready-to-use nutrient solution is 1–3 mg Fe/l (i.e. 7.7–23 g Mikrochelat Fe-13 per 1000 l).
- When preparing concentrated solutions, increase the Mikrochelat Fe-13 dose proportionally.
- Fertigation in organic substrates and soil (nutrient solution supplied periodically - multiple times during plant vegetation). When using Mikrochelat Fe-13 with other fertilisers in 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 total amount of Mikrochelat Fe-13 in the growing season (in split doses, max. 2 kg/ha per cycle):
- 5–10 kg/ha (pome and stone fruit trees, nuts),
- 4–8 kg/ha (grapevine, fruit bushes, strawberry, vegetables, ornamental plants).
SOIL SPRAYING/WATERING or TOP DRESSING after mixing with other soil fertilisers:
- Spray soil with a solution (Mikrochelat Fe-13 iron chelate) before sowing or planting seedlings or use together with other soil fertilisers.
- For fruit trees (e.g. pear tree), perform soil spray after vegetation starts or at another recommended time. Perform soil spray (coarse droplets) on cloudy and humid days or during rain.
- Recommended total amount of Mikrochelat Fe-13 in the growing season:
- 5–10 kg/ha (pome and stone fruit trees, nuts),
- 10–20 kg/ha (grapevine),
- 3–10 kg/ha (fruit bushes, strawberry, vegetables, ornamental plants).
Doses can be adjusted considering individual plant needs and growing conditions. Avoid using solutions with concentration exceeding 0.15% (1.5 kg fertiliser/1000 l water) at low air humidity. When applying foliar treatments in protected cultivation, do not exceed 0.15% concentration.
