Fertilizer Application

   
        Hi, welcome back to my blog. For this entry, I want to share with you about activity we have done in week 6. In this week, we have learned a lot things about fertiziler. First of all, we need gathered at plantation workshop to listen briefing from Madam Salwa.

6.1 Madam Salwa introduced to students about fertilizers.

Madam Salwa introduced and explained to students about type of fertilizers and how to apply the fertilizer. Madam Salwa also show sample all type of fertilizers to students.

6.2 Types of fertilizers in the workshop

 6.3 Madam Salwa explained to students how to identify the composition of nutrient in fertilizer

Micronutrient

• Fertile soil contain sufficient amount of micronutrient to meet the plant’s requirement
• The micronutrients consist of seven essential elements: boron, copper, chlorine, iron, manganese, molybdenum, and zinc.
•  These elements occur in very small amounts in both soils and plants, but their role is equally as important as the primary or secondary nutrients. 
• A deficiency of one or more of the micronutrients can lead to severe depression in growth, yield, and crop quality. 

Macronutrient

• Fertile soil contain sufficient amount of macronutrient to meet the plant’s requirement

• Plants need relatively large amounts of nitrogen, phosphorus, and potassium. These nutrients are referred to as primary nutrients. 

• The three secondary elements, calcium, magnesium, and sulfur, are required in smaller amounts than the primary nutrients. 

Secondary macro nutrients such as:

-Calcium (Ca), Magnesium (Mg) Sulfur (S)

• Micro elements are also known as trace elements and sometimes people even call them the "multi vitamins" for plants. 

• The micro elements of plants are made up of:

-Iron (Fe), Zinc (Zn), Manganese (MN), Boron (B),

    Molybdenum (Mo) and Copper (Cu)

Deficiency symptoms 

                                            Mn Interveinal chlorosis & stunting

                                             B            General stunting, white young leaves 

                                             Mo Similar to N deficiency

                                             Cl           Chlorosis & necrosis of leaves

Composition of nutrient in fertilizer

For your information, Severe foliar symptom of oil palm,

•  Spears and fronds are often collapsed and yield is negligible
• In such cases, Ganoderma fruiting bodies and lesions are often readily seen on the bottom parts of the palm
