Phosphate for raining

Texture and colour of rainy day soil

The colour of the raining day soil is alot darker and has a rough, crumbly texture which seperates each grain.

texture and colour of soil for sunny day

The colour of the soil is a lightish brown with a rough grainy, sandy feel

Possible parent rock for both rainy and sunny day

The possible parent rock for both raining soil and sunny soil is Sandstone as most of Sydney's base is sandstone, the moisture level for both was relatively low also suggesting that the soil was sandy and easily drained common for a base of sandstone.

Geological and topographical information

Centennial park the area i have chosens parent rock is Sandstone, as most of Sydney is. The topographical aspects to my chosen area are mostly flat surfaced with approx two hills around the East and North area which arent lead directly

Today Friday the 15th i completed all my testing for both sunny and rainy days in the allocated areas around my chosen pond. I found out also that my organic heating and moisture heating for my soil samples should have been the same, so to improve this for next time i will keep the heating and period of heating the same amount. Tomorrow i will add graphs for my results of each test to my blog.

Wednesday the 13th i completed testing for the pH of soil and weighed my soil in order to cook tonight to find moisture content. Today i discovered the tare button and realised i didnt need to take away the basins weight as tare equals zero and anyweight ontop of that eg: soil is weighed, this is much simplier and an easier way to record results.

Today Tuesday the 12th i did my pH testing for both water and soil. The soil results were alot lower (approx 2 pH lower) suggesting the rain made the soil more acidic and the water was also (approx 1 pH) lower than sunny day of testing as fertilisers (or other human activity chemicals that are basic such as soaps) had more time to penetrate into the ground and running off into the pond making the soil and water more basic.

Yesterday Monday the 8th i completed the testing of salts which took a very short amount of time as i was aware of what had to be done and i also had more than one test running at a time. The results suggested that rain did not necessarily effect the salt content in both water and soil as the results were similar with high contents of salt.

Sunday the 10th i collected all my samples for a raining day and visually noticed that the pond appeared much cleaner without sludge on top of the water.

Organic content for sunny day

Turbidity results for sunny day

Today Thursday the 7th i re weighed organic content and recorded results, this lesson i also tested turbidity which meant all of my results for the first group of testing were completed. I’m planning on getting my samples for a raining day on Sunday as it is forecast to rain and on Monday begin my testing of pH, i believe this week will take a smaller amount of time as i have more experience for each test and i have learnt from my faults that more than one apparatus can be set up during testing.

Completed test for presence of salt in soil and water for a sunny day

Today Wednesday the 4th i completed testing for both soil and water samples of the presence of salts and repeated each are sample 3 times. The tests were very slow and i alomst ran out of time therefor next time i do testing after a raining day i will set up three flasks in order to complete the tests with enough spare time to clean the lab.The results of todays testing reflects that salts in both water and soil were relatively high in the overall averages.Also today i weighed each of my soil samples in order to take them home tonight to find the moisture and organic content, tomorrow during lunch i will re weigh them to find the moisture content and on thursday night take them home leave in oven for longer and re weigh them in order to record organic content.

Completed testing for pH of water and soil for sunny day

Today Tuesday the 5th i tested the pH for soil and water samples on a sunny day. I repeated each test 3 times in order to gather an average for each area within Centennial park, while doing these tests which each took alot of time especially to repeat i also completed presence of Phosphates in water. This was a good strategy as i was able to complete 3 tests in a short period of time.
My results for pH for both soil and water were similar results, with no outstanding numbers below or above.
Phosphate results were also similar in results for each section of Busbys pond.
Tomorrow i will be testing for presence of salt in both soil and water samples.
