Science Xingnong has answered the question of yellow leaves many times. Iron deficiency has also been explained many times. For friends who often read Science Xingnong articles, this question is practically a giveaway. When you see yellow leaves, how do you solve it? First look at new versus old leaves, second look at the vein pattern. If it does not match the above, then consider other situations.

(Iron deficiency in soybean)

From the photo, the soybean clearly shows signs of iron deficiency, commonly known as nutrient deficiency, and spraying some ferrous sulfate can quickly relieve the symptoms.

Looking at the photo, the yellow leaf area is on the young leaves at the top, which points to the two elements iron and magnesium. Then look at the green veins, which indicates iron deficiency! Isn't it simple? I hope everyone can smoothly solve similar yellow leaf problems in the future. Below are a few photos of iron deficiency in different plants so that everyone can have a better understanding of iron deficiency.

Next, let me explain the role of iron in the plant body, hoping everyone can gain a deeper theoretical understanding. Ferrous ions are one of the components of chlorophyll, and many photosynthetic enzymatic reactions require their participation, while ferrous ions also participate in enzymatic reactions in the mitochondria. Therefore, for plants deficient in iron, first the amount of chlorophyll synthesized is insufficient, which shows as yellow leaves, and second, photosynthesis and respiration decline, causing the plant to grow slowly.

Generally speaking, alkaline soil is more prone to iron-deficiency yellow leaves, and sandy land shows this quite prominently. For such fields, iron must be supplemented in a timely manner every year. Note that iron supplementation is not soil fertilization; the utilization rate of that kind of fertilizer is too low. It is best to use foliar spraying to improve the utilization efficiency of iron.

Second, because the iron element is relatively inert, once fixed in the plant body it is not easily transferred, so for iron deficiency in plants it first shows on the young leaves. Therefore, for iron-deficient plots, we also often find the phenomenon of heart leaf albinism. This is also a feature by which we can promptly discover iron deficiency in plants.
