Too Much Iron On Lawn: Effects And Solutions | Lawn Mower Sale

In this article too much iron on lawn we will discuss the effects of this phenomenon on your lawn health and the ways to recover it from the trauma because of it. Like human beings and animals plants also requires a specific amount of iron for their survival. Iron deficiency in human and animals can cause different health issues; there are also health problems in plants as well as because of lack of proper amount of iron.

Iron is vital for plants because it supports them for creation of chlorophyll as well as supporting them creating favorable environment for different chemical processes.

But too much of iron is toxic and has adverse effects on plant health. It can weaken and eventually killing your plants if your lawn have more than the required amount of iron.

It is important to note that plants have only the capability of absorbing ferrous iron particles from the soil while other types of iron particles not have the ability to affect your plants.

Alarming Levels of Iron in Your Lawn Soil

If your lawn soil comes with too much of iron then your plants will absorb excessive amount of it so as a result they will suffer from different types of excessive iron related diseases.

According to research conducted by K. Kampfenkel, M. Van Montagu and D. Inze in Belgium if your lawn soil has iron content levels is at 100 mg or more then the situation is extremely danger for your plants. In this scenario your plants will feel the effects of this excessive iron in quick span of time; just needs 12 to 24 hours.

If your lawn is suffering from iron deficiency then your lawn plant will also have related health issues but the noticeable symptoms will take more time to become apparent.

Effects of Too Much Iron on Chlorophyll

Your lawn plants need iron for chlorophyll but in small amount. If there is too much iron in soil for absorption then your plant chlorophyll fluorescence begins to change so too much iron can affect the functioning of chlorophyll itself. This change in chlorophyll materially affects its ability to appropriately absorb energy from sunlight. Sunlight is one of the important factors for creating food for plant through photosynthesis.

Effects of Too Much Iron on Synthesis

Plants come with ability to synthesize chlorophyll as well many of their own nutrients on a cellular basis, also including vital proteins. If plants absorb too much iron from soil then it affects drastically these processes making the environment difficult for different types of these necessary reactions on cellular levels.

This too much iron not only making the environment difficult for creating proper amount of chlorophyll but also hindering the process of making ample amount of sugars for your plant growth and survival. The extra sugar is stored for harsher seasons.

Nutrients Absorption

Increase in iron level also affects the plant ability to receive nutrients from the soil. So the plant draws less amount of nutrients from soil. It means that your lawn plants will not receive the required amount of important substances such as nitrogen, phosphate etc. which they need for proper growth and fight against different types of diseases.

So this excessive amount of iron drastically affects your plants health from different angles, causing severe decay of vital tissues in plants leaves and stems so the ultimate result is the plant death.

Plant Responses for Absorbing Iron

Plants lack the mechanism for dealing with excessive iron content in soil but they have the ability to absorb the required amount of iron especially in case when there is iron deficiency. Plants come with enzyme called a chelate reductase. This enzyme makes the iron absorption easier. Plants also have the system for lowering down this enzyme level when there is sufficient level of iron or the level is high.

How Much Iron Your Lawn Does Grass Need?

Your lawn grass needs chlorophyll for photosynthesis. Iron is necessary for creation of chlorophyll. If your plant lacks the ability to generate sufficient amount of green chlorophyll in young grass then the leaves come with yellowish green and yellow veins. This situation is called iron chlorosis. In case of severs iron chlorosis the yellow leaves turn almost white.

The temporary solution for iron deficiency is spraying iron product on grass but it is a temporary solution. The ideal long term solution for iron deficiency is bringing the soil pH to correct level.

Causes and Diagnosis of Iron Deficiency

Compacted soil, alkaline soil and high levels of phosphorus from excessive fertilization reduce the capability of grass to receive required amount of oil from soil. Cold weather is another cause of iron deficiency because it suppresses the activity of microbes that hinders the iron uptake. Similarly wet soils or excessive dry weather or lack of sunlight also reduce the uptake of iron. This is the reason that grass grown in shade develops iron chlorosis. The easy way to diagnose iron deficiency is to look at the grass.

Keeping the Soil pH at Ideal Level

Soil pH below 7 is acidic while above 7 is alkaline. The ideal pH level is in range of 6 to 7. Iron deficiency is more serious and common in alkaline soil when the pH level is 7.5 or above. If you want to solve the iron deficiency problem for long term then you have to lower the pH. For lowering soil pH in following ways;

  • Add diluted sulfuric acid to irrigation water
  • Or applying 5 to 20 pounds of elemental sulfur per 1,000 square feet of soil will lower down the soil pH and enhances the ability of grass to absorb iron naturally

 How to Add Iron to Soil

  • Spray products come with chelated iron on your lawn grass for 3 to 4 weeks. It will improve its color. The method is especially effective when applied after mowing.
  • Use concentrated forms of insoluble iron oxide directly to soil is comparatively inexpensive method. But this method is not effective in those conditions where the soil pH is very high.
