Monitoring and Controlling Potassiumand Phosphorous Content of Soil with

Maintained Acidity LevelPresented by:

Acot, Jose Joel Jr. L. Adante , Renz Paulo D.C.Loteria , Elmer Joseph D. Zapanta , Jed Ellison C.

Thesis Adviser/s:Engr. Mary Ann Latina

IS IT POSSIBILE TO CREATE A SYSTEMTHAT CAN SIGNIFICANTLY IMPROVETHE YIELD PERFORMANCE OF THEPHILIPPINE MANGO INDUSTRY?

YES!!

Our Objectives

1. Design a monitoring and control system forthe potassium and phosphorus content ofsoil with maintained acidity level.

2. See if the system is working efficiently.

SIGNIFICANCE To easily determine significant changes in the

soil.

Execution of proper actions when certainparameters of soil exceed the ideal levels.

Helps the farmers yield fruits efficiently.

Scope and Delimitations The system monitors soil pH, potassium and phosphorus

only.

It does not include other parameters such as: nitrogen soil moisture hydrogen oxygen carbon calcium magnesium sulfur

HOW DO WE MONITOR ANDCONTROL SOIL CONTENT?

DETERMINATION OF RECOMMENDEDTIME INTERVAL

Behaviour of soil absorption can be observedwith respect to time.

To determine at what time soil parameters arenormalized.


How did we do it?

Span of 120 minutes

Every ten (10) minutes we recorded readings

RECOMMENDATION Add other kinds of soil nutrients to be monitored

and controlled Sensors will automatically remove itself from the

soil after monitoring is done Automatic refilling system for the fertilizers can

also be implemented Sleep feature for the system can be added to save

power Memory feature can be added for data analyzing

purposes and a GUI that displays a graph for it. Focus on other types of soil and other

plants/trees.
