Fertilizer Calculation

Cherry cultivation requires a fertilizer calculation for balanced application of essential nutrients such as nitrogen, phosphorus, and potassium (NPK) to achieve high yields and quality produce. Each nutrient element serves different functions and has distinct effects:

Nitrogen:

• Necessary for the growth and development of cherry trees.
• Aids in keeping leaves green and facilitating photosynthesis.
• Enhances fruit set and quality.

Phosphorus:

• Promotes root development and increases the plant’s resistance to diseases.
• Supports the formation of seeds and fruits.
• Facilitates early maturation.

Potassium:

• Facilitates water uptake and nutrient transport.
• Increases resistance to diseases and pests.
• Thickens the fruit skin and extends shelf life.

Sample Calculation for an Adult Cherry Orchard:

If you expect a yield of 30 kg from an adult cherry tree, the average nutrient amounts lost are as follows:

• Nitrogen : 0.195 kg
• Phosphorus: 0.048 kg
• Potassium : 0.183 kg

Example: Total nutrient requirement calculation for a garden consisting of 100 trees:

• Nitrogen : 1000 trees x 0.195 kg/tree= 195 kg
• Phosphorus: 1000 trees x 0.048 kg/tree = 48 kg
• Potassium : 1000 trees x 0.183 kg/tree = 183 kg

Soil Analysis and Fertilization:

After determining the existing nutrient levels in your soil through soil analysis, you can calculate the fertilization amount by subtracting these amounts from your total requirement. For instance, if your nitrogen requirement is 195 kg and your soil analysis shows 95 kg of nitrogen, then your required nitrogen amount is 100 kg.

Fertilizer Selection:

Urea fertilizer is commonly used for nitrogen. Urea fertilizer contains 46% nitrogen.

Fertilizer Quantity Calculation:

Required nitrogen amount (kg) / Nitrogen content in fertilizer (%) = Required fertilizer amount (kg)

Example: 100 kg nitrogen / 46% nitrogen = 217.4 kg urea

Fertilizer Bag Count Calculation:

Required fertilizer amount (kg) / Fertilizer amount per bag (kg) = Required bag count

Example: 217.4 kg urea / 50 kg/bag = 5 bags of urea

Result:

In this example, for a cherry orchard consisting of 1000 trees with a yield of 30,000 kg of cherries, 5 bags of 50 kg urea fertilizer are needed.

Important Notes:

These are general information purposes only. For the most accurate information regarding cherry fertilization programs, consult the Ministry of Agriculture and Forestry or agricultural engineers. Exercise caution not to over-fertilize. Excessive fertilization can harm both the soil and the environment. Consider your region’s climate conditions, soil type, and cherry variety when preparing a fertilization program.

I hope this information helps you understand the importance of NPK fertilization in cherry cultivation!
