SOIL LAB: The Wealth Beneath Your Feet Purpose: To determine potential growth based on tests of physical characteristics such as pH‚ fertility and consistency. Pre-Lab: TO start off our investigation‚ we had to gather soil. Our group decided to get it from below a tree‚ right next to the trunk. In terms on fertility‚ we rated our soil to be a 4 (1 being the least fertile‚ 10 being the most). We rated it rather high because it was in a place where it had not been tampered with making it better

growth and germination of plants lie the nutrients they receive from the soil. The nutrients required for growth are classified into two groupings‚ macronutirents and micronutrients. Macronutrients are those that are needed in very large amounts‚ and whose absence can do a great harm to the development of the plant life. These nutrients include calcium‚ nitrogen‚ phosphorus‚ and potassium‚ and are very sparse in most soils‚ making them the primary ingredients in most fertilizers. The other‚ more

Specific Environments Abstract: The thing that I did was analyze soil to see if bacteria could live in that environment. The reason why I did it was because I wanted to find out where in the environment bacteria and fungi can live. In order to do my study I had to collect a sample of soil and put it in a dish. After I did that I could look at it underneath a microscope. I found that bacteria did in fact live in the soil so the soil was a sustainable environment for the bacteria to live. Introduction:

processes occur near the surface of the Earth and are powered by the energy from the sun. In this essay I will talk about the process of mass wasting (Lutgens‚ Tarbuck‚ & Tasa‚ 2011). Under tremendous strain from gravity‚ mass wasting is the movement of soil and rocks being pulled down. Mass wasting evens can be considerably manipulated by climate. Frequent freeze and thaw cycles can affect rocks because the water can seep into the rocks and then freeze. This will in turn cause the rocks to expand and

In the absence of any of the elements‚ plant can not complete their life cycle and these can not be supplemented by other elements. They are essential because they are important to plant functions. There are 17 essential plant nutrients. Carbon and oxygen are absorbed from the air‚ while other nutrients including water are obtained from the soil. Plants must obtain the mineral

Considerations It is generally accepted that phytomining is greener than conventional mining practices. In environments with metal-contaminated soil‚ phytominers can recollect metal pollutants from the soil‚ thereby restoring the soil to health. Still‚ growingmass amounts of plants also takes a toll on the land used for cultivation. Industrial farming practices deplete the soil and overgrowing biocrops has the potential to permanently alter an area’s ecology. Economic Viability If the scale of production

EXPERIMENT 3 DETERMINATION OF ORGANIC MATTER BY WALKEY- BLACK WET OXIDATION METHOD OBJECTIVE: This method determines the percentage of organic carbon and organic matter in the soil. INTRODUCTION The soil sample is suspended in standard potassium dichromate (K2Cr2O7) solution to which concentrated sulphuric acid is then added. The heat generated on adding the sulphuric acid and the presence of chromic acid creates strong oxidizing conditions. The excess chromic
