\n

Symptoms of nutrient deficiency<\/p>\n

Plants need nutrients to grow.
\nThe non-mineral nutrients of plants are:
\nhydrogen (H),
\noxygen (O), and
\ncarbon (C).
\nThese nutrients are found in air and water.<\/p>\n

Avocados Lack of Trace Elements The other nutrients come from the soil.<\/p>\n

Soil nutrients are divided into two categories according to the quantities required by the plants.
\nMacroelements and micronutrients (trace elements).
\nThe macronutrients are nitrogen, phosphorus, potassium, calcium, magnesium and sulfur.
\nThe trace elements that need only trace elements are iron, manganese, boron, zinc, copper, molybdenum and chlorine.
\nThese nutrients are essential for plant growth.
\nThe plants will grow normally until they run out of one or two nutrients at a time.
\nThen growth will stop from lacking them.
\nIf the nutrients are deficient or too abundant, then the plants will be deformed and have a damaged color.
\nThe yellow leaves e.g. can be caused by one or more nutrient deficiencies.
\nIt is much better to do a soil or leaf analysis to show which nutrients are low before you start a crop.<\/p>\n

Primary macroelements.<\/p>\n

\u2022 Nitrogen – Nitrogen (N)
\n\u2022 Phosphorus – Phosphorus (P)
\n\u2022 Potassium – Potassium (K)<\/p>\n

Secondary macroelements<\/p>\n

\u2022 Calcium – Calcium (Ca)
\n\u2022 Magnesium – Magnesium (Mg)
\n\u2022 Sulfur (S)<\/p>\n

Microelements<\/p>\n

Indicatively some small elements
\n\u2022 Boron-Boron (B)
\n\u2022 Molybdenum Deficiency – Molybdenum (Mo)
\n\u2022 Iron (Fe)<\/p>\n

\n

Avocado Lack of Trace Elements Primary macronutrients<\/a><\/h3>\n

<\/h3>\n
<\/div>\n
\n

Nitrogen-Nitrogen (N) Deficiency<\/p>\n

 <\/p>\n

Generally<\/p>\n

It is a primary nutrient for plant growth.
\nPlants convert nitrogen into essential proteins for the growth of new cells and chlorophyll.
\nTomato flowers or fruits can rarely be affected.<\/p>\n

Symptoms<\/p>\n

Sick plants, red stems, slower growth.
\nRapid yellowing of the lower leaves, a phenomenon which progresses to the top of the plant.
\nThe disease is caused by the Adelomycete Mycorellosiella fulva.<\/p>\n

Treatment<\/p>\n

Add Nitrogen-containing fertilizers.
\nWith proper treatment the plants will recover in about a week.<\/p>\n

\n

Phosphorus-P deficiency (P)<\/p>\n

Generally<\/p>\n

It is essential for photosynthesis and acts as a catalyst for energy transfer within the plant.
\nPhosphorus helps build a healthy and strong root system, it is also a vital ingredient for flowering and seed production.<\/p>\n

a. Symptoms on the leaves.<\/p>\n

Reduction of growth rate, red stem.
\nThe smaller leaves are dark green-blue.
\nThe lower leaves turn yellow and wither.
\nExcessive phosphorus availability can cause potassium deficiency.<\/p>\n

b. Wrist symptoms.<\/p>\n

Blotchy Ripening on the tomato fruit.
\nGreen and yellow areas (like a mosaic) appear on the surface of the red fruit.<\/p>\n

Treatment<\/p>\n

Add Phosphorus-containing fertilizers.
\nLeaves that have already been affected will not recover but the new leaves and growth will continue normally.<\/p>\n

<\/div>\n
\n

Potassium Deficiency (K)<\/p>\n

 <\/p>\n

Generally<\/p>\n

Activates the production and circulation of sugars and starches, as well as growth by cell division.<\/p>\n

Symptoms<\/p>\n

Deficiency is usually more pronounced in tall plants, which show necrotic spots on the lower leaves and the stem is red
\nThe leaves are pale or yellow and their edges turn brown and turn upwards.<\/p>\n

Treatment<\/p>\n

Add fertilizers containing Potassium.<\/p>\n

<\/div>\n
\n

Secondary macroelements<\/h3>\n
<\/div>\n
\n

Calcium Deficiency – Calcium (Ca)<\/p>\n

 <\/p>\n

Generally<\/p>\n

It helps in the structure of the cells and is necessary for the strength of the plants<\/p>\n

a.Symptoms in the strains.<\/p>\n

The young tips of the plant die. Tomato stalks begin to dry starting at the edges.
\nThe leaves die, starting with the new leaves and shoots that are fertile and contain flowers.<\/p>\n

b.Symptoms in the Network – Zeukton<\/p>\n

The extreme leaves and flowers are dried. The leaves acquire red-brown shades.<\/p>\n

c.Symptoms on the Wrist.<\/p>\n

Dry or black top of the fruit (Blossom End Rot).
\nThe grids are drying.
\nThe dry or black top of the fruit (Blossom End Rot) appears on the extremities.<\/p>\n

Treatment<\/p>\n

Treat with foliar fertilizer, use a teaspoon of Dolomite Lime in 1 Liter of water and spray the leaves 1-2 times a day, until you see the condition improve.<\/p>\n

<\/div>\n
\n

Magnesium Deficiency – Magnesium (Mg)<\/p>\n

 <\/p>\n

Generally<\/p>\n

Require as part of chlorophyll for photosynthesis.
\nProduction decreases and the old leaves turn white or yellow<\/p>\n

a. Symptoms on the leaves.<\/p>\n

Central chlorination and green bands at the edges of the leaves.<\/p>\n

b. Symptoms in the Network.<\/p>\n

Central chlorination and necrosis of the leaves. The fruits (tomatoes) show “green backs”.<\/p>\n

c. Symptoms in the plant.<\/p>\n

Appearance in greenhouses. Central chlorination and necrosis of the leaves.<\/p>\n

Treatment<\/p>\n

Add Magnesium to the water \/ solution very carefully<\/p>\n

<\/div>\n
\n

Sulfur Deficiency – Sulfur (S)<\/p>\n

Generally<\/p>\n

It participates in the synthesis of proteins and is part of the amino acids, cystine and thiamine, which are the building blocks of proteins.
\nIt has an active role in the structure and metabolism of plants.<\/p>\n

Symptoms<\/p>\n

Plants suffering from sulfur deficiency, show yellowing in the new leaves accompanied by small mutant leaves which are round in the shape of a roll, then the yellowing extends to all the leaves.
\nThe leaves become hard and brittle.<\/p>\n

Treatment<\/p>\n

Rainwater, plaster<\/p>\n

\n

Microelements<\/h3>\n
<\/div>\n
\n

Lack of Boron-Boron (B)
\nGenerally<\/p>\n

Helps in the production of sugar and hydrocarbons.
\nIt is Ideal for seeds and fruit growth<\/p>\n

a. Symptoms on the branches.<\/p>\n

The stems become rigid.
\nNew flowers die and growth is reduced.
\nThe lateral branches grow, preventing the plant from growing in height.
\nThe leaves acquire a strong need of purple, brown and yellow.<\/p>\n

b. Symptoms in the wrists.<\/p>\n

The fruits of the tomato have no seeds and have a corky texture.
\nMaturation is not uniform.<\/p>\n

Treatment<\/p>\n

Organic material and borax<\/p>\n

\n

Molybdenum Deficiency – Molybdenum (Mo)<\/p>\n

 <\/p>\n

Generally<\/p>\n

helps build protein and enhances the plant’s ability to absorb nitrogen from the atmosphere.<\/p>\n

Symptoms<\/p>\n

The leaves are somewhat chlorotic.
\nIntense rotation of the leaves.
\nThe leaves are dried from the edges.<\/p>\n

Treatment<\/p>\n

Treat with foliar fertilization using Molybdenum-containing fertilizers.<\/p>\n

<\/div>\n
\n

Iron (Fe) Lack<\/p>\n

 <\/p>\n

Generally<\/p>\n

is a basic catalyst for the production of chlorophyll and is used in photosynthesis.<\/p>\n

Symptoms<\/p>\n

The leaves turn yellow or white while the glands remain dark green.
\nPH imbalances lead to non-absorption of iron by plants.<\/p>\n

Treatment<\/p>\n

Treat with foliar fertilizer using Iron-containing fertilizers.
\nAlways use Iron Chelate so that it is immediately available to plants.<\/p>\n
