Ten (10) Nutrient Deficiencies Common in Garlic

Updated: Mar 22





Garlic Plants, like most plants need nutrients to grow and develop. Nutrients are essential for photosynthesis, the process by which plants use sunlight to convert carbon dioxide and water into sugar and oxygen. Nutrients are also necessary for respiration, the process by which plants convert sugar into energy. The nutrients plants need to survive are divided into two groups: macronutrients and micronutrients. Macronutrients are needed in large amounts, while micronutrients are needed in small amounts.


The macronutrients that plants need are:

  • Carbon

  • Hydrogen

  • Oxygen

  • Nitrogen

  • Phosphorus

  • Potassium

  • Calcium

  • Magnesium

The micronutrients that plants need are:

  • Iron

  • Manganese

  • Zinc

  • Copper

  • Boron

  • Molybdenum

Plants absorb nutrients from the soil through their roots. The nutrients are then transported to the leaves, where they are used in photosynthesis and respiration. If a plant does not have enough of a nutrient, it will show symptoms of nutrient deficiency. Symptoms of nutrient deficiency can include stunted growth, yellowing leaves, and wilting.


There are a number of ways to prevent nutrient deficiency in plants. One way is to use a balanced fertilizer. Another way is to test the soil to determine the nutrient content. If the soil is deficient in a nutrient, you can add a fertilizer that contains that nutrient. Nutrients are essential for the growth and development of plants. By providing plants with the nutrients they need, you can help them to be healthy and productive.


Ten (10) nutrient deficiencies that are common in garlic plants include:


  • Nitrogen

  • Sulfur (sulfate)

  • Iron

  • Boron

  • Copper

  • Manganese

  • Zinc

  • Molybdenum

  • Potassium

  • Phosphorus



Nitrogen

Plants absorb nitrogen from the soil through their roots. The nitrogen is then transported to the leaves, where it is used to build proteins and chlorophyll. Nitrogen is also necessary for the production of ATP, which is the energy that plants use to power their growth and development. Nitrogen is an essential nutrient for plants, but they can only absorb it in the form of nitrate (NO3-). Nitrate is the most common form of nitrogen in the soil, and it is also the form that is most readily absorbed by plants. Once plants have absorbed nitrate, they use it to build proteins and chlorophyll. Proteins are essential for the structure and function of plant cells, and chlorophyll is essential for photosynthesis. Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into glucose, a type of sugar. Glucose is the primary source of energy for plants, and it is also used to build other organic molecules, such as proteins and lipids. Nitrogen is also necessary for the production of ATP. ATP is the molecule that plants use to store and release energy. ATP is used by plants for a variety of purposes, including:

  • Photosynthesis

  • Respiration

  • Cell growth

  • Protein synthesis

  • Carbohydrate storage

Without nitrogen, plants would not be able to grow or reproduce. Nitrogen is an essential nutrient for all living things.

Plants can also absorb nitrogen from the air through their roots. This is called nitrogen fixation, and it is done by certain bacteria that live in the soil. These bacteria can convert nitrogen gas (N2) into ammonia (NH3), which is a form of nitrogen that plants can absorb. Nitrogen fixation is important because it provides plants with a source of nitrogen that is not available from the soil. Nitrogen fixation also helps to replenish the soil with nitrogen, which is important for maintaining soil fertility.


Sulphur

Sulfur is a macro-nutrient that is essential for plant growth. It is a component of proteins, amino acids, and vitamins. Sulfur is also necessary for chlorophyll formation, which is essential for photosynthesis. Plants absorb sulfur from the soil through their roots. The sulfur is then transported to the leaves, where it is used to build proteins and chlorophyll. Sulfur is also necessary for the production of vitamins. Sulfur is a mobile nutrient, which means that it can move easily from one part of the plant to another. If a plant has more sulfur than it needs, the excess sulfur can be stored in the leaves or the roots. However, if a plant does not have enough sulfur, it will show symptoms of sulfur deficiency.


Sulfate and sulfite are both ions that contain sulfur. Sulfate is the oxidized form of sulfur, while sulfite is the reduced form.

Sulfate is found in soil and water, and is absorbed by plants through their roots. It is then used in a variety of plant processes, including photosynthesis, respiration, and the synthesis of proteins and enzymes. Sulfite is also found in soil and water but is not absorbed by plants in the same way as sulfate. Instead, it is converted into sulfate by plants. Sulfite can also be produced by the breakdown of organic matter, such as decaying plants and animals. Sulfite is a reducing agent, which means that it can donate electrons to other substances. This can be harmful to plants, as it can damage proteins and enzymes. Sulfite can also cause plants to produce hydrogen peroxide, which is a toxic substance. Sulfate is not as harmful to plants as sulfite. However, it can still cause problems if it is present in high concentrations. Sulfate can also cause plants to produce hydrogen peroxide, although this is usually not as severe as the damage caused by sulfite. In general, sulfate is beneficial for plants, while sulfite can be harmful.


Symptoms of sulfur deficiency include:

  • Yellowing leaves

  • Stunted growth

  • Poor fruit production

If you suspect that your plant is sulfur deficient, you can add a sulfur fertilizer to the soil. Sulfur fertilizers are available in a variety of forms, including organic and synthetic fertilizers.
