Fertilizer Calculation

1. Fertilizer Calculation Ms. Abiera Paulyn C.

2. Three types of fertilizer Material Combination of a single fertilizer materials. Combination of an incomplete, and single fertilizer. Combination of complete, incomplete and single fertilizer.

3. 1. Combination of a single fertilizer materials: Let us know first the following -->To easily know which of the categories does an equation belong to try to observe the given fertilizer materials. -->A fertilizer materials comprise of nitrogen, phosphorous and potassium.

4. Single fertilizer materials is refer to a fertilizer who has only one value. For example: >OS-(Ordinary Superphosphate)0-20-0 >KCI-( Muriate Potash)0-0-60 --> In ordinary superphospate , phosphorous is the only one who has a value which is 20%. --> Same also in KCI in which potassium is the only element who has a value which is 60%.

5. 2.Combination of an Incomplete and single fertilizer materials -->An Incomplete fertilizer materials refers to a fertilizer who has two value. For example > DAP( Diammomium Phosphate)16-20-0

6. 3. Combination of complete, incomplete and single fertilizer materials. For example: Complete fertilizer- 14-14-14

7. Solving combination of single fertilizer material. Given: >RR( recommended rate)=90+60+30 >FM( fertilizer materialas ) AS( Asmmonium sulfate)20-0-0 OS(Ordinary superphosphate)0-20-0 KCI( Muriate of potash)0-0-60 > Area= 1ha

8. Formula To solve the amount of FM using the combination of single fertilizer materials use the formula below; Amount of FM= RR( Kgnutrient / haxha /20trient in FM x 100.

9. Solving combination of complete, incomplete and single fertilizer Materials > Observe how to solve combination of complete, incomplete and single fertilizer materials using the formula below; Given: RR(Recommended rate)90+60+30 FM(Complete fertilizer) 14-14-14 ( DAP) 16-20-0 ( AS) 20-0-0 Area=1ha FM=RR( kgnutrients / haxha /nutrient in FMx100

10. Example Solve first the complete fertilizer. Substitute the formula with the given value. > 14-14-14= 30kgNPK/1hax1ha/14x100= 214.3 Solve for DAP substitute the formula with the given value. Use the potassium of the recommended rate. Use the value of phosphorus of DAP as % nutrient in FM. >DAP= 30kgP205/1hax1ha/20nutrient in FMx 100=150kg

11. Group the students into two group. Each group need to solve the following. Group 1 solve the following kg of fertilizer materials using combination of single fertilizer materials. 45kg of AS 2. 32kg of KCI Group 2 solve the following kg of fertilizer using combination of complete fertilizer 1.50kg NPK 2.40kg NPK

12. Quiz Time: Please get 1 whole sheet of paper for our short quiz. And solve the following kg of fertilizer materials using a combination single fertilizer materials. 1. 54kg of AS 6.55kg of AS 2. 25kg of OS 7.28kg of KCI 3. 40kg of OS 8.20kg of KCI 4. 50kg of KCI 9.19kg of OS 5. 30kg of AS 10.35kg of AS

13. Assignment For your assignment please list down the different crops that use of fertilizers.
