Lab: Investigating Soils
Observations/Data
Record the observations and/or data you collected here.
Describe the color, feel, and appearance of each soil sample.
Sample 1: Play ground sand: khaki colored, feels rough, has more sand than rocks.
Sample 2: Potting soil: black/brown-ish colored, feels some what soft, has little pieces of bark
(woody stem, branches, and roots of plants.)
Sample 3: Backyard soil: Orange-red, feels lumpy, muddy look alike.
What is the texture of each soil sample?
Sample 1: coarse texture because the aggregates are larger hence drains fetter
Sample 2: when breaking down by soil microbes becomes finer
Sample 3: smooth, and sticky when its formed into a ball
Describe the way that water drained from each soil sample.
Sample 1: with the sand praticles being large, the water drained pretty quick
Sample 2: it absorbed the water
Sample 3: it took a while to drain out since it absorbed most of it

Analysis
Answer the following questions about this lab.
1. How did the feel of each soil relate to its texture?
Soil relates to its texture by the type of environment
2. Based on your observations, what kind of texture led to the fastest water drainage? What kind of texture led to the slowest water drainage? How do you think texture influences a soil’s porosity and permeability?
The coarse texture of backyard soil drained water faster. potting soil was the slowest water drainer because instead of draining it absorbs. Soil texture and structure greatly influence water infiltration, permeability, and water holding capacity.
3. Which, if any, of your three soil samples would be best suited for good agricultural production? Explain your answer.
I feel like potting soil would be a good agricultural production because it provides high quality in nutrients and a right mount of drainage.
