Determining Soil Nutrient Levels

Great Essays
Aim
The objective of the experiment is to explore the process of simple analysis techniques and representative sampling in determining soil nutrient levels. Soil samples collected from Flinders Campus were used to determine their pH, salinity, ammonium, nitrate, phosphate, and nitrite levels.
Introduction
Unless there is a specific problem detected, the most common reason for undertaking soil analysis is to detect the levels of essential nutrients (Guo, 2009). The commonly analysed nutrients in most samples submitted to the laboratory include macronutrients like potassium, phosphorus, and nitrogen as well as their pH levels. McGrath and Skotnikov (1996) pointed out that knowledge about soil nutrient levels, in addition to relative comprehension

    Analysis of soil chemical and biological properties Soil chemical analysis and enzymes like urease, protease and nitrite reductase were carried out in the soil analysis laboratory, Guangxi University, Nanning, Guangxi Province, China. Soil pH analysis (soil:water = 1:1) performed by pH meter and Soil organic carbon was determined by dichromate oxidation (Walkley and Black, 1934). Total N in soil was determined by Semimicro-Kjeldahl method (Bremmer and Mulvaney, 1982). Nitrate nitrogen (NO3−-N) and exchangeable ammonium nitrogen (NH4 +-N) in soil was determined using FeSO4/Zn reduction method described by Carter (Carter, 1993). Total P in soil was determined using Sodium carbonate fusion described by Carter (Carter, 1993).…

    Within this horizon, it is common for there to be clay films present on the peds and lining pores. The soil pH is about neutral, around 6.8. The horizon also has a gradual smooth boundary between the next horizons (National Cooperative Soil Survey 2000). d. Bt2 horizon This horizon is about 15-27 inches in depth and is a silty clay loam. It is of a yellowish brown (10YR 5/4) color when dry and a dark yellowish brown (10 YR 4/4) color when moist.…

    3.2.3 Principle The Liquid Limit (LL) is the boundary between the liquid and plastic states of a soil. It is the minimum moisture content at which the soil will flow under its own weight. As obtained from the standard test, it is defined as the water content at which a trapezoidal groove of specified shape (12.5 mm) cut in moist soil, held in a special cup, is closed for 10 mm of its length after 25 taps on a hard rubber plate. The liquid limit is directly proportional to the compressibility of the soil. At this limit the soil possesses low shear…

    Particle size distribution Introduction The purpose of this lab was to determine the particle size distribution of a particular soil sample by carrying out sieve analysis and hydrometer analysis tests. For the sieve analysis test, a graph for percent finer versus the grain size was plotted from the data collected. The graph was used to determine whether the soil sample was fine-grained or course-grained. Calculations for uniformity and gradation were then done to determine whether the soil was well graded, poorly graded or gap graded. For the hydrometer analysis test, the soil sample was dispersed in water so that the particles settled at different velocities with time.…

    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. CBR tests are carried out in different sizes of molds to find out the effect of confinement. The results show that the CBR value of the coir mat reinforced subgrade when soaked shows nearly twice the CBR value of the unreinforced (i.e. without the…

    However, the most common shear boxes are square, 60 mm x 60 mm. A load normal to the plane of shearing may be applied to a soil specimen through the lid of the box. Provision is made for porous plates to be placed above and below the soil specimen. The direct tests are usually performed by placing the soil sample in a shear box which is split into two halves, Figure…

    Factors affecting transport of the pollutant at Watershed Nature Centre a. Physical factors: Parent material, water circulation, colour, Parent material: Phosphate salts that are released from rocks through weathering usually dissolve in soil water and are absorbed by surrounding plants. Because the quantities of phosphorus in soil are generally small, it is often the limiting factor for plant growth. This limiting condition or low bioavailability can be as a result of Oxides of Iron and Aluminium in the soil which has a very high affinity and can be strongly absorbed by their amorphous compound. That is why humans often apply phosphate fertilizers on farmland.…

    The soil texture determines the fertility of the soil, its water holding capacity and how the soil can be managed. The purpose of this lab was to become familiar with determining soil texture by using various methods. Particle Density and Bulk Density Particle density is the measure of the density of the soil solids, with no pore space. This is important as it helps increase understanding of the soil texture and helps to determine the bulk density and porosity. Bulk density is the measure of relative soil compaction, as expressed in total mass per total volume.…
