How to get iron out of leaves?
Sprays that deliver iron directly to leaves give iron-chlorotic leaves relief. Use a water-soluble, all-purpose, acid-boosting fertilizer at a rate of 1 tablespoon fertilizer to 1 gallon of water, and spray affected foliage and so il. At temperatures above 85 degrees Fahrenheit, spray the soil only. Alternatively, use liquid iron at a rate of 1 1/4 ounces of liquid product per 1 gallon of water, or according to label instructions. Spray the leaves for a fast, but short-lived fix. Always wear protective eyewear and gloves when working with chemicals, and check the label before spraying specific plants, especially edibles. Spray iron carefully. All iron products can stain concrete and stone.
Why is iron important for plants?
Plants rely on iron for the most basic aspects of photosynthesis. Without this essential nutrient, plants can't create chlorophyll and in turn, they can't produce flowers and fruit. Fortunately, most U.S. soils contain enough iron for healthy plant growth. Excess iron can cause iron toxicity and affect other plant nutrients. Before you add iron to your garden soil, make sure a deficiency exists and understand its cause. Identifying the culprit helps put your garden back on track.

Dilute 2 ounces of iron sulfate in 3 to 5 gallons or water and apply to it the soil. This amount should cover 1000 square feet, advises Clemson University Cooperative Extension Service.
How to fix iron deficiency in plants?
If your plants are showing signs of iron deficiency, apply a foliar spray for a quick fix. Both ferrous sulphate and iron chelate can be used as foliar sprays. This is not a permanent fix, but will help to restore plant color while you're amending the soil. Several nutrients, including iron, are more efficient as a foliar spray. Follow all package instructions for application. For most of these sprays, spray at a 10- to 14-day interval.
Why is iron insoluble in soil?
On the other end of the spectrum, some acid-loving plants are prone to iron chlorosis. Another reason for iron deficiency is that the soil has too much calcium, which makes the iron insoluble.

Plant-Soil Interactions: Nutrient Uptake
Plants often face significant challenges in obtaining an adequate supply of these nutrients to meet the demands of basic cellular processes due to their relative immobility.Symptoms of nutrient deficiency may include stunted growth, death of plant tissue, or yellowing of the leaves caused by a reduced production of chlorophyll, a pigment needed for photosynthesis.In a world of continual global climate change, it is important to understand the strategies that plants have evolved to allow them to cope with some of these obstacles.Macronutrients are the building blocks of crucial cellular components like proteins and nucleic acids; as the name suggests, they are required in large quantities.Second, some plants possess mechanisms or structural features that provide advantages when growing in certain types of nutrient limited soils.When some micronutrients accumulate to very high levels in plants, they contribute to the generation of reactive oxygen species (ROS), which can cause extensive cellular damage.
Long-term nitrogen fertilization of paddy soil shifts iron-reducing
Total extractable Fe in both soils treated with FER, GOE and CTR remained constant at about 155, 75 and 63 μmol g−1 throughout the incubation, respectively (Figures 1d–f).Total CH 4 production after 4 days was largely suppressed by up to 35% by the addition of FER (31–35%), but not much by GOE (5.5–12%) in both soils (Figure 2a).After 4 days, the extent of increase in 13C atom percentage of CH 4 and CO 2 in the presence of Fe (III) oxyhydroxides was slightly but significantly (P<0.05) greater than that in the CTR treatment in both soils, respectively (Figures 2c and d).The incorporation of 13C into rRNA was corroborated by parallel incubation of microcosms with 12C-unlabeled acetate as the substrate (defined as unlabeled treatments).In contrast, the bulk of bacterial rRNA in all labeled treatments had apparently shifted toward ‘heavier’ BDs and now banded between 1.791 and 1.806 g ml−1.However, an enrichment of archaeal rRNA in the ‘heavy’ fractions was not detected in all labeled treatments (Supplementary Figure 1).Figure 3 Quantitative distribution of density-resolved bacterial 16S rRNAs obtained from non-fertilized (NF; a–c) and N-fertilized (N; d–f) soil slurries treated with ferrihydrite (FER; a and d), goethite (GOE; b and e) and control (CTR; c and f) after 4-day anoxic incubation with either labeled (13C) or unlabeled (12C) acetate as the substrate.Bacterial template distribution within rRNA gradient fractions was quantified with real-time reverse transcription PCR.The normalized data are the ratio of the copy number in each gradient fraction to the maximum quantities from each treatment.Nevertheless, in both soils, a terminal restriction fragment of 159 bp in the ‘heavy’ fractions significantly increased in relative abundance following the addition of Fe (III) oxyhydroxides (Supplementary Figures 2–3a and c).We clustered these samples based on the phylogenetic lineages that they contain via the application of principal coordinate analysis to a matrix of unweighted UniFrac distances.Ellipses in solid line denote the samples from the 13C-labeled treatments for NF (circles) and N (triangles) soils.High-quality bacterial and archaeal sequence reads were assigned to different phylogenetic taxa at genus level by ribosome database project Classifier, respectively.Among these potential 13C-acetate-assimilating populations, five genera including Geobacter, Dechloromonas, Clostridium, Bacillus and Solibacillus were stimulated by FER addition in the NF soil (Figure 5a).Figure 5 Net proportional changes in relative abundance of the potential 13C-acetate-assimilating bacterial populations at genus level in NF (a) and N (b) soils following the addition of ferrihydrite (FER) and goethite (GOE).The net proportional change is calculated as the difference in the relative abundance of the targeted microorganisms between the FER (or GOE) and CTR treatments in each soil.Figure 6 summarizes the relative abundance of putative dissimilatory iron-reducing bacterial community in both soils at genus level.Six genera (belonging to Proteobacteria, Acidobacteria and Firmicutes), including Geobacter, Geothrix, Desulfobulbus, Clostridium, Anaeromyxobacter and Desulfovibrio were detected in both soils (Figure 6).Figure 6 Average relative abundance of putative dissimilatory iron-reducing bacterial community structures at genus level in NF and N soils under field conditions.The possible relationships between putative dissimilatory iron-reducing bacterial community structure and environmental factors were discerned with canonical correspondence analysis (Supplementary Figure 10).
