How to Accurately Fertilizer Calculation Online Needs for Trees
Step 1: Search for the Tree
Type the tree for which you want to calculate the fertilizer amount into the search box. Trees matching in the database will be displayed as a list. Select the most suitable tree from the list and wait for the page to load.”
Step 2: Perform Soil Analysis
Enter the laboratory results of soil samples taken from different parts of the land where the trees you want to calculate fertilizer for are located, collected from depths of 30 cm and 60 cm, along with the size of your land, into the calculation tool below. Calculate how many kilograms of NPK value are in the land area you have entered
Step 3: Calculate NPK Requirements for the Tree
Enter the expected fruit yield of the tree for this year, the number of trees in the area where you conducted the soil analysis, and the age of the trees. In this calculation, we will determine the tree’s NPK requirements and calculate the necessary NPK amount by subtracting the NPK content in the soil.
Step 4: Amount of Fertilizer to be Purchased
The required NPK values we calculated in the table above have been automatically transferred to this table. After selecting the type of fertilizer you will purchase, the total amount of fertilizer will be calculated automatically based on the ratios of the fertilizer you choose. To avoid purchasing excess fertilizer, the minimum required amount will be highlighted in yellow and selected automatically. If you have re-conducted the soil analysis or tree fertilizer calculation, pressing the calculate button will automatically update the values
Fertilizer Calculation Based on NPK Values (Table 1)
| Element | Required Amount (kg) | Fertilizer Ratio (%) | Required Fertilizer Amount (kg) | Deficit/Excess |
|---|---|---|---|---|
| Nitrogen (N): | ||||
| Phosphorus (P): | ||||
| Potassium (K): | ||||
| Selected Fertilizer Amount (kg): | ||||
Result
Selected Fertilizer:
Step 5: Remaining Amount of Fertilizer to be Purchased
The fertilizer ratios indicated in Table 1 may not fully meet your needs. Therefore, to determine the amount not covered by the fertilizer you have purchased, the remaining amount from Table 1 will be automatically transferred to Table 2, and the necessary minimum amount will be calculated based on the other NPK ratios of the fertilizer you choose
Fertilizer Calculation Based on NPK Values (Table 2)
| Element | Required Amount (kg) | Fertilizer Ratio (%) | Required Fertilizer Amount (kg) | Deficit/Excess |
|---|---|---|---|---|
| Nitrogen (N): | ||||
| Phosphorus (P): | ||||
| Potassium (K): | ||||
| Selected Fertilizer Amount (kg): | ||||
Result
Selected Fertilizer:
Step 6: Calculate the Remaining Amount of Fertilizer to be Purchased Based on the Amount Left in Table 2
The fertilizer ratios indicated in Table 2 may also not fully meet your needs. Therefore, to determine the amount not covered by the fertilizer you have purchased, the remaining amount from Table 2 will be automatically transferred to Table 3, and the remaining amount will be calculated based on the other NPK ratios of the fertilizer you choose. In the Results section, you can find the type and amount of fertilizer selected in each table.
Fertilizer Calculation Based on NPK Values (Table 3)
| Element | Required Amount (kg) | Fertilizer Ratio (%) | Required Fertilizer Amount (kg) | Deficit/Excess | ||
|---|---|---|---|---|---|---|
| Nitrogen (N): | ||||||
| Phosphorus (P): | ||||||
| Potassium (K): | ||||||
| Selected Fertilizer Amount (kg): | ||||||
Result
Selected Fertilizer 1:
Selected Fertilizer 2:
Selected Fertilizer 3:
