Soil biology

Radishes themselves are moisture-loving plants; therefore, it is significant that they receive an adequate amount of water, allowing the soil to be moist, but not overly saturated (Biology Coach, 2015). In general, water is significant for the health of a plant in the way it transports important nutrients throughout the plant. From this point, nutrients are drawn from the soil and used by the plant. Seed germination itself is defined as the process where the seed sprout for growing, and future development

Soil respiration is the greatest terrestrial contributor of carbon dioxide to the atmosphere and can be a direct indication of agricultural crop and soil health (Schlesinger and Andrews, 2000). The amount of carbon dioxide generated from soil respiration is influenced by several factors including, temperature, moisture, and carbon/nitrogen ratios in plant litter amongst others (Biology 208 Lab Manual 2016). The occurrence of soil respiration is as a result of root respiration which signifying healthy

The effects of Lead-Nitrate contamination on the plant Brassica rapa Ernest J. Tiller III, Corey Biology Department Birmingham-Southern College Date: October 24, 2016 Teacher: Jennifer Kelly Abstract In my biology class we conducted an experiment to determine if there was a direct correlation between the concentration of lead levels in soil and the effect it has on plant synthesis and plant height. The specimen used in the experiment is a species of plant, Brassica rapa. Seeds of B. rapa

The control group in this experiment is the group that is grown normally to test the effects of the rest of the experiment’s independent variables. Growing Brassica rapa plants in the control group will allow the other science experiments to be compared to the normal growth of a common Brassica rapa plant. The normal growth of these plants will be important in measuring the other plants to see how their sizes compare and to show how an untreated plant would grow. Because of the nature of the control

Benefit You? Soil needs to breathe under the surface of vegetation, and when we talk about that, we talk about aeration. Everything that is living needs oxygen for combustion of fuel to procure energy, for the preservation of life. Therefore, it becomes very crucial to take care of the lawn soil, in order to facilitate the beauty of the landscape. Lawn aeration could be as simple as removing chunks of soil around the plant or digging holes to allow oxygen, fertilizers, and water to enter the soil. In technical

Building a Compost Lab Darius Dixon Biology 5TH Period 6/7/10 Introduction Composting is nature’s way of recycling and is the key to healthy soil and a healthy environment. Composting is a cost- efficient way of getting rich natural soil for a very cheap price. There are numerous types of compost bins available to make; each enable the growth of lawns and gardens. A compost pile is usually made from fruit and vegetable scraps, newspaper and grass clippings, worms (that act as decomposers)

Assessing Economic Benefit of Various Lupin Management Methods This study aimed to assess the nutrient advantage and the underlying economic benefit of brown manuring vs. green manuring of three different lupin cultivars for boosting soil nitrogen reserves for the following crop. Fertiliser input costs continue to escalate as a result of market demand and coupled with the increasing herbicide resistant issues; producers are turning to the increasingly popular tool of manuring crops in an attempt

believe succession will take place because the newest dunes do not have rich enough soil to support more complex plants like trees and shrubs growing in the areas that have already gone through later stage succession. The data supported our hypothesis. The area with the most vegetation was the C index. There were certain plants in abundance in certain indexes, however, most plants remained in every index. The soil also changed throughout each index. It went from sandy, in an area closer to the water

ation: Biotechnology Using Plants to Reverse the Effects of Environmental Problems. Introduction In the last century the population has increased by 6 billion and by 2050 is expected to reach 8 Billion, this coupled with global industrialisation has placed huge stresses on the environment, affecting sustainability and causing buildups of organic and inorganic contaminants throughout the biosphere, most notably in the rhizosphere (Ward & Singh, 2004). Phytoremediation coming from the Greek word

entering or leaving (river/lake) can be a function of the hydrology and topography system. Water from sources such as direct/indirect precipitation, surface runoff from snowmelt, or storm water from exposed rock or packed soil, or groundwater inflow from the aquifer will react with the soil or bed/sedimentary rock and dissolved them (as the phenomena knowns weathering condition).Therefore these variable sources can add a critical deposit into the river or lake (surface water) constituents. For instance
