As the grid sampling is becoming popular, several people have started taking more soil samples with keen interest. This situation brings more queries about soil labs like why these labs are getting distinct results for the same field and same sample, why recommendations for using fertilizer vary from labs to labs. There are countless yet reasonable explanations for these variations.

Soil sample reporting includes two different services-

1. The analytical results that are the nutrients content level exist in the sample.
2. The recommendation what amount of fertilizer should be used for the crops.

Lab differences happen in both areas; this is why experts need to look every area distinctly.

The initial reason for distinct analytical results is the sorts of chemical extractants used by soil laboratories. On primary stage, it may not seem logical for labs to make use of distinct chemicals to extract same nutrients, but there are special reasons to do the same. A fewer reasons are-

• Instrument type used to determine the nutrient in the extractant
• The techniques and quality used for detecting the nutrient
• The reporting method for results

The general issue in understanding soil test reports is in understanding the relationship between the distinct measure units that labs use for reporting results.

About soil build up

This is a longer term philosophy of fertilizer recommendations. This recommendation is ideal for farmers that own land and want to earn more profits for several years. The main reason or logic behind this approach is that farming will be done in better way and the farmer can avail more yield when all of the roots get abundant supply of nutrients via soil. When the soil levels increased, profits and yield also get increased at faster rate than costs. To make this happen, farmer need to manage the crop in proper way to protect the yield from other factors. Weather is responsible for good or bad yield. So, soil lab tests are important to determine suitable nutrient level requirement that matches the weather condition.

At the end, people will find that they need to make adjustments to lab recommendations as they have unique information that the soil lab cannot find. There are farmers who cannot afford a strong soil buildup program and have rented farming land on yearly basis. There are areas where soil lab recommendations won’t help farmers and thus, the knowledge and experience work well for them.

• Complete Your NDT Testing Using Specialized Equipments

The noninvasive techniques help in determining the integrity of material, component or structure; or quantitatively measure some characteristics of an object. In other words, it helps in checking or measuring without doing harm.​

Material testing is generally done by manufacturers once they are done with their project. Yet, quality is the result of both the material and the process. If they use defective material to form a product, then there are chances of getting defective product. So, this is where you will require material testing instruments. You should know that quality cannot be put in after the fact and to produce materials, you must understand the properties to predict the manufacturing outcome.

For stamping and forming operations and for several products, a material profile will assist in determining differences in materials from suppliers. Moreover, many of the most preferred metals and plastics, textiles, polymers, and composites show some stress in a material, which is proportional to the strain used for producing it.

Manufacturing foundries and the engineers working in it should understand the mechanical properties of materials. It is necessary as the performance of the structure is initially determined by the amount of deformation allowed or permitted.

Next significant property is ductility, i.e. the ability for plastic deformation in shear or tension. Ductility of the materials controls the amount in which a material can be cold formed. This formation process is used when engineers need to cast automobile bodies or wire products.

Some professionals take help of destructive and non destructive methods to determine ductility and strength of construction materials. They use specialized material testing instruments, such as Izod impact testing machine, Rockwell hardness tester, tensile testing machine, torsion testing instrument, universal testing machine, and twin tensile testing machine. Each machine has its own features and advantages.

Bitumen is an oil based substance, semi-solid hydrocarbon product that is produced by removal of the lighter fraction from heavy crude oil during refining process. This purified bitumen is known as refined bitumen. In many countries, bitumen is commonly called as asphalt cement or simply asphalt. But, there are places where asphalt is the term used for a mixture of sand, small stones, filler, and bitumen, this mixture is used as a road paving material. These materials are being tested for their strength and hardness using bitumen testing instruments by professionals.

Refined bitumen is used for construction purposes- majorly as a constituent of products used in paving and roofing applications. As per the requirements of the end use bitumen is made to specifications. Experts acquire it either by refining process or blending.

As per the survey, it is found that presently world is using approx 102 million tonnes bitumen every year. Around 85% of all the bitumen produced is used by road constructing bodies as a binder in asphalt for roads, pavements, footways, runways, car parking etc.

Asphalt is generally produced by mixing sand, gravel, and crushed rock with bitumen that works as a binding agent. Some manufacturers of bitumen also use polymers to alter its properties as per the application for which the asphalt is initially intended.

And 10% of the global bitumen production is used by builder and construction industry for roofing applications, where its waterproofing qualities are invaluable. The rest of the 5% of bitumen is used for sealing and insulating purposes in a variety of building materials, like pipe castings, paint, and carpet tile backing.

What makes people confuse about bitumen?

Petroleum bitumen is mistakenly considered as tar. Although coal tar and bitumen are black and sticky yet they are distinctly different substances in terms of chemical composition, origin, and properties. Coal tar is produced by simply heating coal to higher temperatures. It is used as the binding agent in road asphalt in early times, today refined bitumen has replaced it.

Experts get this refined bitumen using bitumen testing instruments & equipment. You can get these instruments from premium suppliers nearby your location.

Geotechnical engineering is a part of civil engineering that is focused on engineering properties and the earth material’s condition. This engineering type includes distinct elements of physics, geology, and engineering to assess the site and determine its suitability for development. Engineers can evaluate previously developed structures with geotechnical testing equipment to help reduce potential hazards that can seriously affect the life of developed structure and prevent any harm to public nearby or within the area.

Geotechnical engineers and professionals make use of plentiful different principles of soil and rock mechanics for below reasons-

• To check subsurface materials and conditions
• To determine related physical/mechanical and chemical attributes of these materials
• To evaluate stability of natural and man-made slopes
• To assess risks that the site conditions present
• To design earthworks and site foundations
• To consistently monitor site conditions, foundation construction, and earthwork.

Most of the time civil design projects apply these geotechnical engineering solutions. However, the use of this solution is just not limited to civil design projects. It is also used by distinct industries like military, resource development industries, and other industries that require construction work on or in the ground.

Normally, geotechnical engineering projects start with reviewing the design elements that are already proposed, so that experts can have a good idea about the requirements for site development. After this part, investigation comes under role that includes subsurface exploration that is aimed towards measuring the rock and soil properties on and below the site.

It is important to consider geotechnical evaluation?

If you are an engineer and working on any construction site, you can never ignore the significance of geotechnical engineering evaluation. It will always remain a part of any site assessment. This is a low-cost method that helps engineers in reducing potential liabilities linked with unidentified site conditions.

The time of evaluation varies greatly depending on project type. Size and scope are some factors that can affect the timelines of geotechnical report generation. This report has detailed graphical logs and information that is tailored to meet the needs of each project.

This evaluation task is done by engineers using specialized geotechnical lab testing to get accurate results. Many manufacturing companies are producing efficient testing equipment range for engineers. You can get your choice of equipment from them at great price.
