Properties of Soil: Agricultural and Water Availability Impacts Claire Murad 2/18/2024

1 I. Introduction The objectives of this lab were to present how the size of soil particles and the natural porosity of sand, clay, and soil would affect the agricultural aspect of plant growth. The purpose of this lab is to test out the two objectives, which help determine the current conditions of the land. Once the current conditions are known the gathered information on what nutrients are needed to make the land deemed harvestable. There could be a deficiency in N, P, and S which is unwanted as agricultural nutrient richness is more successful in plant growth. On the other hand, there could be an influx of nutrients causing increased growth in plant structure. The sand, clay, and soil samples are tested to support the statement of how particle size will affect porosity and lead to the outcome of how much nutrients a plant is receiving. II. Results In Activity 1, the layer of clay in the collected soil is very minimal in comparison to sand and soil, at 5%. Next, the depth of sand at 35% comes second behind the depth of soil at 60%. As soil comes up first, it supports the high percentage present, making up most of the collected soil sample. In Activity 2, the clay took the longest amount of time (140s) to formulate a single water droplet. The soil took the shortest amount of time (6s) to create a water droplet. Lastly, the sand took 21s to create a water drop. In activity 3, there was an error with a part of the lab that did not allow it to be completed. However, the predictions of the pH level results would indicate a more basic soil for both, between 6-7. The soil should be a more neutral base to induce plant growth. In Activity 4, The collected soil sample (50 feet) had nitrogen-depleted (N0), phosphorus-depleted (P0), potash adequate (K2), and the other soil sample (10 feet) had nitrogen-depleted (N0), phosphorus-deficient (P1), and potash sufficient (K3).

The sand absorbed all the water given, the clay hardened after absorbing the water, and the collected soil showed the most apparent layer among all samples.
