As a building material it is used in our houses and even our breakfast juice is enriched with iron. We can also discover iron in the periodic table, under the symbol\u00a0<em>Fe<\/em>, derived from the Latin name\u00a0<em>Ferrum. <\/em>Iron is a heavy metal that is used either as two- or three-valent iron (Fe<sup>2+<\/sup>\u00a0or Fe<sup>3+<\/sup>) or in compounds (oxides, salts). For our plants, only the Fe<sup>2+<\/sup>\u00a0interesting, because they can absorb them and feed on them.<\/p>\n<p>The Fe<sup>3+<\/sup> is not directly available for the plants. The bound iron can be released from different minerals by weathering. In this weathering, iron ions are released, but several factors influence the availability of iron, such as pH and humidity. In moist soil with a pH of 6 to 6.5, there is usually a high amount of<sup>2+<\/sup>. If the pH value rises to over 6.5 and you also have to contend with drought, this availability decreases more and more. The iron is bound and is no longer available to the plant.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Why_do_plants_need_iron\"><\/span><span id=\"Warum_benoetigen_Pflanzen_Eisen\">Why do plants need iron?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Iron is not a direct component of the leafy green (chlorophyll) responsible for photosynthesis, but it plays an important role in its formation.

The respiratory chain is part of energy metabolism. Energy is generated from the nutrients absorbed \u2013 a very important process for all living beings. Iron is often also part of different enzymes that play different roles in metabolism.<\/p>\n<p>The Fe<sup>3+<\/sup>\u00a0is not directly available for the plants, as it must first be used in the soil in Fe<sup>2+<\/sup>\u00a0converted or chelated. Plants can only be<sup>2+\u00a0<\/sup>or chelated Fe<sup>3+<\/sup> Record. Chelates are complexes that can be absorbed by the plants as whole molecules. The word &#8220;chelate&#8221; comes from the Greek\u00a0<em>chele<\/em> and means as much as claw or crab scissors \u2013 and that also describes well what chelates are in the first place.<\/p>\n<p>In the middle of a chelate is an ion, often a heavy metal like iron. Larger organic molecules cling to it and hold it. These compounds are very stable, nutrients can be absorbed more easily by the plant as a chelate.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Detecting_iron_deficiency_in_plants\"><\/span><span id=\"Eisenmangel_bei_Pflanzen_erkennen\">Detecting iron deficiency in plants<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>How does an iron deficiency in our plants show up? A symptom of iron deficiency is the yellowing of leaves, whereby the leaf veins remain green \u2013 these are so-called chloroses. These chloroses first form on the young leaves. When the deficiency becomes more pronounced, necrosis (dying tissue) develops from the edge of the leaf.<\/p>\n<p>When an iron deficiency occurs, a lack of chlorophyll, protein, and energy also occurs. Therefore, the growth as well as the yield of the plant decreases. The color of flowers can also fade and they can remain smaller overall. The roots are usually short in case of iron deficiency and have many short side roots. If the iron deficiency is not treated, your plants can even die \u2013 but only if it is a severe deficiency.<img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-10679\" src=\"https:\/\/gardender.com\/wp-content\/uploads\/2020\/12\/Raspberry-with-iron-deficiency.jpg\" alt=\"Raspberry-with-iron-deficiency\" width=\"750\" height=\"450\" srcset=\"https:\/\/gardender.com\/wp-content\/uploads\/2020\/12\/Raspberry-with-iron-deficiency.jpg 750w, https:\/\/gardender.com\/wp-content\/uploads\/2020\/12\/Raspberry-with-iron-deficiency-300x180.jpg 300w\" sizes=\"(max-width: 750px) 100vw, 750px\" \/><\/p>\n<p>Iron deficiency is often found, especially on calcareous soils, where iron is precipitated by the calcium carbonate present there. As a result, the iron can no longer be absorbed. Some plants can already show on which soil they grow \u2013 for example, soils on which a lot of flattish, nettles, or dandelions grow are often chalky. Further information on chloroses\u00a0is also collected here in a special article for you.<\/p>\n<p><strong>Summary Signs of iron deficiency in plants:<\/strong><\/p>\n<ul>\n<li>Presence of chlorosis, with the leaf veins remaining green<\/li>\n<li>Signs first appear on the young leaves<\/li>\n<li>Later, necrosis from the edge of the leaf begins<\/li>\n<li>Inhibited growth<\/li>\n<li>Low yield<\/li>\n<li>Pale, small flowers<\/li>\n<li>The occurrence of short roots and many side roots<\/li>\n<\/ul>\n<p>Dryness and compaction may also be reasons why the plant cannot absorb iron. Therefore, after a prolonged drought, it is worth watering the plants properly. Wet and compacted soils can also be a hindrance to the iron absorption of the plants. Such soils often inhibit root growth and there is a lack of oxygen or at the same time an excess of carbon dioxide. Mechanical loosening and the incorporation of mainly organic fertilizers can put an end to compaction.<img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-10680\" src=\"https:\/\/gardender.com\/wp-content\/uploads\/2020\/12\/Wine-with-iron-deficiency.jpg\" alt=\"Wine-with-iron-deficiency\" width=\"750\" height=\"450\" srcset=\"https:\/\/gardender.com\/wp-content\/uploads\/2020\/12\/Wine-with-iron-deficiency.jpg 750w, https:\/\/gardender.com\/wp-content\/uploads\/2020\/12\/Wine-with-iron-deficiency-300x180.jpg 300w\" sizes=\"(max-width: 750px) 100vw, 750px\" \/><\/p>\n<p>Another important factor that causes iron deficiency is the excess of other\u00a0heavy metals in the soil. The transport and absorption of iron can be inhibited when many ions of chromium, copper, cobalt, zinc, manganese, or nickel romp in the soil. Rindenhumus can contain a lot of manganese and especially a zinc excess can lead to an iron deficiency.<\/p>\n<p>In general, it can be said that problems have to be expected as soon as the balance of the ions in the soil is disturbed. The interaction between iron and phosphorus is particularly interesting. If there is a lot of phosphorus in the soil, it is possible that these two nutrients combine and form iron(III) phosphate. We know this compound as a snail grain, but it can also form in the soil and thus bind the nutrients.<\/p>\n<p><strong>Here we have briefly listed the iron deficiency triggers:<\/strong><\/p>\n<ul>\n<li>Too high pH<\/li>\n<li>Waterlogging<\/li>\n<li>Dryness<\/li>\n<li>Inhibited root growth<\/li>\n<li>Imbalance and excess of other nutrients<\/li>\n<li>High phosphorus content<\/li>\n<\/ul>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-10681\" src=\"https:\/\/gardender.com\/wp-content\/uploads\/2020\/12\/Tomato-with-iron-deficiency.jpg\" alt=\"Tomato-with-iron-deficiency\" width=\"750\" height=\"450\" srcset=\"https:\/\/gardender.com\/wp-content\/uploads\/2020\/12\/Tomato-with-iron-deficiency.jpg 750w, https:\/\/gardender.com\/wp-content\/uploads\/2020\/12\/Tomato-with-iron-deficiency-300x180.jpg 300w\" sizes=\"(max-width: 750px) 100vw, 750px\" \/><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Apply_ingenuity_iron_fertilizer\"><\/span><span id=\"Eisenduenger_richtig_anwenden\">Apply ingenuity iron fertilizer<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>If your plants are now affected by an iron deficiency, there are several ways to feed them.

The advantage of leaf fertilization is that the effect occurs very quickly. Since the fertilizer is not introduced into the soil, it cannot be washed out and is effective despite soil dryness. However, leaf fertilization can only be used with a low concentration to avoid damage to the leaves.<\/p>\n<p>This form of fertilization must also be used more frequently and the fertilizers are unfortunately also slightly more expensive than other iron fertilizers. It is also possible to use iron fertilizer regularly as a preventive measure and thus counteract deficiency symptoms. However, always follow the product description and the recommended doses. When using iron fertilizers, it is also important not to use them in the sun and at temperatures above 77 \u00b0F \u2013 this can lead to plant damage.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Iron_fertilizer_in_the_water\"><\/span><span id=\"Eisenduenger_im_Giesswasser\">Iron fertilizer in the water<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>You can also add iron to the water. For this purpose, dissolve the iron fertilizer according to the product description in the watering water and add it to the plants. In the water, a quantity of 0.1 to 0.2 oz of iron per liter of water is sufficient for proper iron fertilization.<\/p>\n<p>Then rinse the watering can thoroughly to remove the last product residues from it. Also, be careful not to soil the soil or your clothing with iron fertilizer. This results in unsightly rust stains, which are either difficult to remove or impossible to remove.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Which_plants_are_often_affected_by_iron_deficiency\"><\/span><span id=\"Welche_Pflanzen_sind_oft_von_einem_Eisenmangel_betroffen\">Which plants are often affected by iron deficiency?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Put simply, particularly depleting cultures are often affected.

The flower lovers among you, who like to have petunias (<em>Petunia<\/em>) on the balcony, will surely have been confronted with an iron deficiency. When chlorosis occurs in the petunias, it is usually an iron deficiency.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Iron_fertilizer_for_lawns_and_against_moss\"><\/span><span id=\"Eisenduenger_fuer_Rasen_und_gegen_Moos\">Iron fertilizer for lawns and against moss<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Even your favorite green lawn can suffer from iron deficiency. This is mostly caused by the soil condition. Some soil contains more iron, others contain less iron. However, in order to be quite sure, you can carry out a soil survey.<\/p>\n<p>One way to use iron fertilizer on the lawn is to combat unwelcome moss. If your lawn is heavily mossed, you can treat the moist moss with iron fertilizer. Before doing so, you should mow the lawn to a length of about 1 to 1.5 in. and then treat the moss with the iron fertilizer (iron (II)sulfate). Iron fertilizer can be used either as granules or, as already described, as liquid fertilizer mixed into the water.<\/p>\n<p>The application should take place in the spring in the months of March or April if the soil is already completely thawed. After that, the moss dies after about two weeks and turns brownish to black. You can then simply remove the moss with a rake or rake. It is especially important that you fill the gaps left by the moss.<\/p>\n<p>After removal, you should sow grass again so that no other weeds or moss settle. If you do this moss removal in spring, this is ideal so that the reseeding can grow well. Do not enter the lawn after using iron fertilizers for about two weeks. Also, keep your pets away from the lawns \u2013 there may be signs of poisoning.<\/p>\n<p>We always recommend supplying your lawn with sufficient nutrients and relying on organic long-term fertilizers. This not only makes your lawn fit and lush green but also spares you the soil life, and can always re-enter your lawn immediately after fertilization. <img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-10683\" src=\"https:\/\/gardender.com\/wp-content\/uploads\/2020\/12\/Moss-lawn.jpg\" alt=\"Moss lawn\" width=\"750\" height=\"450\" srcset=\"https:\/\/gardender.com\/wp-content\/uploads\/2020\/12\/Moss-lawn.jpg 750w, https:\/\/gardender.com\/wp-content\/uploads\/2020\/12\/Moss-lawn-300x180.jpg 300w\" sizes=\"(max-width: 750px) 100vw, 750px\" \/><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Iron_fertilizer_for_aquariums\"><\/span><span id=\"Eisenduenger_fuer_Aquarien\">Iron fertilizer for aquariums<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Aquarium plants also need nutrients, because when the plants show chloroses, they also lack iron. The fact that an iron deficiency in the aquarium is not so rare is shown by the fact that the first aquarium fertilizer in the trade was an iron fertilizer. A general quantity recommendation cannot be given for the application. Each aquarium is individual in terms of filling volume, filter systems, stocking, feeding, and planting.<\/p>\n<p>Optimal iron content in an aquarium is 0.03 to 0.1 mg\/l. This can be easily checked with test strips from the zoo department. Another indicator of sufficient iron content is the growth of water lenses. If you have water lenses in the aquarium and enough iron, then the lenses multiply well.<\/p>\n<p>If there is a lack of iron, the water lenses adjust their growth. Unfortunately, fertilization in the aquarium \u2013 no matter what nutrient is involved \u2013 is often associated with the formation of algae. Therefore, you should be very careful when dosing and rather fertilize a little less than too much.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Is_iron_fertilizer_toxic\"><\/span><span id=\"Ist_Eisenduenger_giftig\">Is iron fertilizer toxic?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In general, iron fertilizers are toxic and you should always avoid physical contact with these fertilizers.

The rust stains are usually difficult to remove or not at all. Be careful with your clothes. It would be a great pity for your favorite trousers if it was soiled with unsightly stains.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Manufacture_iron_fertilizers_yourself\"><\/span><span id=\"Eisenduenger_selbst_herstellen\">Manufacture iron fertilizers yourself<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>If you don&#8217;t want to buy iron fertilizer, there is another option: that of your own production. This will protect your wallet and, of course, the environment. Because plants absorb iron as an essential nutrient, it is naturally contained in vegetable waste,\u00a0bokashi,\u00a0or\u00a0<a href=\"https:\/\/gardender.com\/banana-peel-as-fertilizer-is-it-useful\/\" target=\"_blank\" rel=\"noreferrer noopener\">compost.<\/a>\u00a0Highly ferrous plant material such as\u00a0spinach,\u00a0chickpeas,\u00a0lentils, or kidney beans is particularly suitable for the production of ferrous fertilizer.<\/p>\n<p>Because the two-valued, more plant-available iron is only available in the compost at a low pH, it can be mixed with lemon juice or orange juice before use as a fertilizer.<\/p>\n<p>Similarly, an old trick works to feed iron to our bodies. Iron nails inserted into an apple oxidize as a result of contact with apple acid. Mixing the apple carvings then crushed under the plant-soil also provides easily plant-available iron. But it&#8217;s even easier: Many plants themselves have such effective tactics for extracting iron from the soil that inserting iron nails into the plant-soil can be enough.<\/p>\n<p>When planting, especially in the container \u2013 to impart plenty of yellow sand can also prevent iron deficiency. Because the yellowing of the sand comes from adhering iron oxides. Another very effective iron supplier is a blood meal, which can be purchased or obtained from your own slaughter.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Iron as a nutrient is mainly used for the formation of enzymes.
