Soil tests

check the health of your soil to know the perfect timing. Generally late summer and early autumn are the best time for the same. Lawn aeration is one of the best ways to take care of your lawn. With this process, you can let the water and air into the soil in order to relieve the compaction. Compaction is a general phenomenon which makes soil tighter and poses a problem for the air and water to reach the soil’s pores. With the help of this system, you can give keep your soil profile in good…

Soil preference of the Red Compost Worms, Eisenia fetida INTRODUCTION Earthworms provide countless benefits to humans, plants and animals, by improving drainage, advancing nutrient accessibility, and providing a steady soil system, helping to develop farm production. They benefit the soil ecosystem by decomposing and recycling organic matter, opening up pores inside the soil to develop its formation and supplying food for predators . By adding nutrients to the soil they inhabit, earthworms are…

CONSISTENCY LIMITS OF A SOIL 3.1 Introduction 3.1.1 Objective To determine the Atterberg Limits of Soils 3.1.2 Learning Outcomes Understand the Principle of Consistency and Atterberg Limits of Clay Soils Describe the Atterberg Limit Tests and their uses Perform the tests and obtain the Atterberg Limits Calculate some Indices (Flow Index, Plasticity Index and Toughness Index) for the Clay Soil 3.1.3 Consistency indices Fine-grained soils are formed in nature by the gradual deposition of soil…

TEST PROGRAM In this chapter, a case study of application of coir geotextile for increasing the CBR value has been presented. This case study is of soil in Assam, India. Assam is a state of India. In this case study attempts were made to increase the CBR value of black cotton soil in Assam using coir geotextile. A number of CBR tests are conducted (both soaked and unsoaked conditions) using samples consisting of soil only and soil with layer of coir mat at different position from the top surface…

will receive water 5 inches in depth as well as the C. vialis. A soil measuring kit will be used to run various tests on the two different plants. A tape measure will also be used to determine the height of the surviving plant. The experimental group will receive the water with the fertilizer that includes nitrates, plotting soil and light from the sun. The control group will receive regular water, with no fertilizer, plotting soil and sunlight. The two plants will compete for the same resources…

Calcium levels in the soil controls soil pH and species richness within a community Hypothesis 1: Calcium levels in the soil controls soil pH. Prediction: An increase in the calcium levels in the soil will make the soil less acidic. Reasoning: Calcium exists mainly in the soil as exchangeable cations (ca^2+) associated with basic anions, which reacts with soil acidity (H) to neutralize it. Analytical approach: Regression Independent variable: Calcium levels Dependent variable: Soil pH…

Plant Science - Seed germination and growth The research question: What is the effect of changing the pH of the soil on the germination and growth of mustard peas? Hypothesis: The greatest number of peas will germinate and will grow the most when the pH is 5 or 7. Theory: Enzymes play a vital role in the cells of plants (especially when growing) and enzymes work best when at their optimum pH value. Moreover, all chemical reactions have an optimum pH at which they work best (Howard and…

He also adds on by stating that “Garden beds improve growing conditions for plants by lifting their roots above the soil”. Providing us with a simple but key explanation of why plants seem to grow faster if planted in garden beds. Hayes says that, “The soil in beds that are raised warms up earlier in the spring and is innovated by certain grasses and by the tree roots”. Recommending several steps to construct a raised garden bed. First…

Montgomery is both entertaining, and an informative read. He expresses how soil is one of the most underappreciated resources, and how humans over time have been a prime factor of soil degradation. This book primarily talks about how human infiltration has gradually continued to raise the rate of soil degradation through deforestation, agriculture, poor erosion control, and disinterest in the subject presented. Agricultural soil loss is not because humanity farms but arises from how they…

population, must come into contact with the environmental medium (Simon, 2014). The environmental mediums are soil, water, air, and biota. The concentration of the pesticide present must be determined in order to calculate a dose. Also, with each individual medium there will be a level of variability and uncertainty that must be considered. Contamination concentrations in the soil will be highly variable. This is due to the application of the pesticide. The areas directly where the…
