Research Hypothesis

• Whats the object of our program?
• To compare the difference between the type of
  soil and the corps yields at the same weather
  condition.
• Corp of Research maize/corn
• Experiment Name G2-Tean

3
Description of Research

• When will we sow? Reap? why choose that?
• Corn rotation weather
• Planting date on May.?good weather to grow
• Reaping date on October.

Experiment (1/2)
5/15

• Set parameter of date Corn rotations interface

rotations interface

7
Experiment (2/2)
Planting 1985/5/15 (135th day)
Harvest 1985/10/30 (303th day)
Irrigation periodicity every 60 day




Fertilizer periodicity every 30 day

Weather condition-FLMI

• Why we choose FLMI?
• Due to the weather (temp season) was extremely
  suitable the corn grow

9
Soil condition

• Type of soil
• DEEP SILTY CLAY
• MEDIUM SILTY LOAM
• SHALLOW SANDY LOAM
• SHALLOW SAND

10
Simulation

• When we finish our parameter set, the next step
  is run SALUS model

11
result 1/4-R022

• R022 type of soil is DEEP SILTY CLAY, and the
  yield of harvest is 2633kg on195th day.

12
result 2/4-R023

• R023 type of soil is MEDIUM SILTY, and the yield
  of harvest is 4627kg on195th day.

13
result 3/4-R024

• R024 type of soil is SHALLOW SANDY LOAM, and the
  yield of harvest is 3483kg on195th day.

14
result 4/4-R026

• R026 type of soil is SHALLOW SAND, and the yield
  of harvest is 3483kg on195th day.

15
Comprehensive result
Harvest day(4-times) and the yield in 4-test area
we found the yield rose abruptly on 4th (the last
time to fertilize) in No.23
16
Building the theme Map

• The result show, different type of soil to get
  the yield of corn in 4 area.

17
Conclusion

• A simple test show that there had a great effect
  not only the yield of corn and type of the soil,
  but also the growing season.
• The texture have powerful influence on yield of
  the crops. (Measure the diameter of soil)
