2. Methods

2.1 Equipment List


  1. For the house
  • Acrylic glass
  • Wooden pillars
  • Trays
  • Balsam and onion shoots
  • Wire gauze
  • Glue
  • Water
  • Nails and hammer


  1. For the soil testing
  • Soil test kit
  • LaMotte Test kit
  • Grinder


2.2 Diagrams of experimental setup


Description:
  • This is a greenhouse measuring 50cm by 30cm by 50cm excluding the roof of the greenhouse. The handle is to show that the bottom door can be opened in order for easier observation.




Description
  • The back of the greenhouse shows that there is a lot of ventilation for the plants and there would not be any heat trapped inside as air can easily flow. It also prevents any rats from sneaking in to destroy the plants.



2.3 Procedures to build the house

To build the house, you would first need to cut out these few pieces of wood (9mm):

Next, you would have to cut out the wire gauze according to these sizes:

Lastly, you would have to paint the wood pieces to ensure that they are waterproof and attach everything together in order to get a functional house, including the wire gauze.

2.4 Procedures to test the soil

  1. Firstly,
We have to get the soil types which are sand, silt and clay.

  1. Secondly,
We would have to test the pH, nitrate, potassium, phosphorus, magnesium, calcium iron using a particular soil test kit and gather all our data in a single table which we can refer to.

  1. Thirdly,
We have to first guess and add the closest amount of soil and mixing it, ensuring the the volume of each sand, silt and clay is recorded and do the testing for all the 7 factors.

  1. Next,
After testing, if the soil does not reach our required nutrient amount, we can add fertiliser (in this case compost).

2.5 Risk Assessment and Management  


2.6 Data Analysis

To test whether our system is working, we are going to do the following:

  • Build a greenhouse
  • Test the soil for pH, nitrate, potassium, phosphorus, magnesium, calcium, iron
  • We will then monitor the growth of the plants over time.
