Innovative Against N-pHacid CHLOROSIS
Plants, like everything else, are excellent parameters that show the acidity of the soil. The most common symptom of chlorosis is yellowing of the leaves. Plants usually show the iron terrain in this way. But sometimes they are able to show the same symptoms in zinc or manganese.
These yellowings are sometimes confused with yellowing from nitrogen and sulfur. The symptoms of iron terrain are unique and most dramatic in young plants. Iron-rich plants are often seen as vascular chlorosis or yellowing veins between green veins.
Severe iron chlorosis occurs on leaves much smaller than normal leaves. These leaves turn yellow and show burnt-out leaf edges at the edge of the leaves. Reviews Iron deficiency decreases the performance of the plant and even causes its death.
If fertilization by nitrogen, potassium, zinc, manganese or sulfur does not correct the yellow leaves, an iron terrain problem can be expected if the plants do not turn to the expected green color. Leaf analysis may, but not always, be helpful in understanding an iron deficiency. Although iron deficiency is not seen in some analyzes, the plant shows iron deficiency. Because the iron element, which is attached between the cell walls, is never functional. But it is detected as iron in the analysis. In this case, a plant nutritionist by showing your example to get help from his comments.

Major Causes of Chlorosis

-High soil pH
- The effect of lime and bicarbonate on chlorosis
-Product conversion to bicarbonate
-Lime chlorosis due to soil and climate
-High carbonate or bicarbonate irrigation water
- Extremely moist and cool soil conditions that cause weak rooting
-Plastic mulch and other soil conditions that prevent gas release
High Soil

Reviews If the soil pH is close to or higher than 7, the presence of iron in the leaf is limited. Low iron availability occurs as a result of reduced iron solubility when the soil pH is above 7. Reviews The presence of zinc is also affected by soil pH. However, this effect is less than the effect of iron exposure. Reviews Lowering soil pH increases iron availability in plants.

The Effect of Lime and Carbonate Presence on Chlorose

May occur due to fertilizers (HCO3) that increase chlorose, lime and bicarbonate.
Increases the pH of carbonate (lime) or bicarbonate. Prevents the ability of the plant to remove iron from soil solution. Reviews Bicarbonate also reduces the use of iron in the plant's own juice. (Marschner 1586). Reviews In other words, bicarbonate reduces the metabolic function of iron in the plant. Chlorosis caused by high lime in soil was observed in blueberries (strawberry). Chlorosis caused by high lime in the soil can last for several months or several years. But with soil acidification, ie pH reduction, rapid recovery is provided.
In descaled soils, ie acidic soils, try to raise the soil pH with small applications annually while giving the correct dose of lime (below pH 4.5) to prevent chlorosis. Agricultural lime applications should be based on soil analysis. The soil should be tested after 6 to 8 months and more lime added if the pH is still low.

Translation of Urea to Bicarbonate

Nitrogenous fertilizers such as urea (46.0.0) can cause chlorosis with reduced lime, because in the decomposition of ammonia and carbon dioxide released by the reaction of urea with water, carbon dioxide is oxidized with water and carbonic acid is removed from the soil solution and converted to bicarbonate. (NH2) 2CO + H2O  2NH3 + CO2
(urea + water  ammonium + carbon dioxide)
CO2 + H2O  H2CO3  H + HCO3
(carbon dioxide + water  carbonic acid  hydrogen + bicarbonate

Chlorosis from reduced lime is often found in Vaccinium species. (blueberries, rhododendrons and azaleas). For these plants, apply nitrogen in the form of ammonium phosphate, ammonium sulfate or the like. Do not use urea if possible. Although urea will be applied, make small applications instead of large ones. Reviews High calcareous irrigation water can cause a high accumulation of bicarbonate in the soil and increase the pH. Reviews Chlorose is most commonly seen in soils with high pH (pH> 8), irrigation with high pH and high bicarbonate water.

Soil and Lime Due to Climate
Reviews Recent research shows that in some grape varieties, lime-derived chlorosis can be caused by a combination of soil and climate factors. Reviews High rainfall, cold soil conditions, winter rains or excessive spring irrigation also limit root growth and root function. With the damaged root function, plants may lose the ability to absorb iron from the soil. This increases the risk of iron chlorosis.
