Good soil is the secret to healthy plants, so the more you can understand your soil, the better. This easy soil texture test will help you determine the percentages of sand, silt, and clay in your soil. Determining the texture of your own soil will guide you in amending it to the perfect balance.
Here are simple step-by-step instructions for testing the texture of your soil. Remove any roots, twigs, or rocks.
Soil Texture Makes A Difference
Step 2: Deposit Soil Sample in Jar Use the shovel to slice off a small cross section of the soil sample. Step 3: Add Water and Detergent to Jar Fill the jar with water, add a teaspoon of detergent, and shake for several minutes until the soil is thoroughly suspended in the water.
Step 4: Wait and Measure The coarse sand particles will settle out first; followed by the darker, finer silt. Last will be the lighter, superfine clay while organic matter will float. If you wait until everything has settled, it can be hard to sort out which is which. To make identification easier, mark the sand level on the jar after one minute, the silt level after hours, and the clay level after two days.
The sample above was taken from my yard. To calculate the percentage, divide the depth of each layer of soil by the total soil depth in the jar, and multiply by The above sample was taken from farmland in eastern North Carolina — note the high sand level and near-absence of floating organic matter. This knowledge will greatly assist me with the amendment process.

Cap and shake for five minutes alternately inverting the jar will suffice.
Allow the jar to sit, undisturbed, for at least 24 hours.Westates, the current carbon vendor to the Chimney Creek plant, has been a supplier since the inception of mill start-up. Due to the increase in magnitude of dump leach solutions, stripping, reactivation and acid wash frequencies together with carbon inventory over the past three years, a significant fraction of the elevated attritioning losses may be attributable to the same.
Insofar as present practice is concerned, the primary objective of the proposed evaluation is to compare carbon from other vendors against Westates, and determine their viability with respect to attritioning and economics.
The program is directed towards medium activity carbon, as the characteristics of the Chimney Creek plant design obviate utilization of high activity carbon. The potential for increased attrition losses with higher activity carbon is an additional factor towards the decision to test medium activity carbon. The most recent plant carbon evaluation was conducted approximately 1. Subsequently, carbon attrition losses have increased steadily creating a significant quantity of fines in the circuit.
Refer to earlier memo Dec 11 for details and a cost breakdown. The current project will focus principally on the attritioning aspects of Westates G carbon as compared to medium activity carbons from four other vendors.
Additionally, activity and loading rates will be investigated briefly. The program is anticipated to commence during the first week of January with an estimated completion time of 6 weeks. Project methodology details follow. Obtain approximately 3 pounds gm of Westates G fresh activated carbon from an unopened bag. Use tube sampler for procuring representative sample. Carefully split entire amount of Westates and other vendor carbon samples to gm, using the micro-splitter.
Split gm samples to gm, and store remaining portion of split in labeled pulp envelope. Split the gm sample once and make certain each split fraction contains gm of sample. Bag and label accordingly. The entire program will require duplication of all tests. Introduce exactly gm of carbon sample into the funnel, by means of a scoop, making certain that the carbon is distributed evenly along the sides of the cylinder. Gently tap cylinder to obtain a level bed. Introduce the sample into the container and record gross weight y.
Place pan in a drying oven at 45 Celsius F and dry for 24 hours. Test for moisture with a watch glass. Cool sample to room temperature and record gross weight z. Save samples for next phase of program. After recording actual weight xtransfer sample into a ml beaker containing gm DI water.
Cover container with a watchglass and allow soaking for 24 hours.Visit Our Sponsor:. Canadians with very hard water are collectively panicking as news that Calgon is no longer being sold in Canada travels through the cloth diapering community. Dramatic much? The news is true.
Calgon is not available in Canada any more. Why not? Here are a few things you can do if you relied on Calgon to soften your water. Test your water hardness. You can pick up water hardness test strips at most hardware-type stores. Just double check that they detect total hardness. You can also order water hardness test strips from Bumbini Cloth Diaper Company. Skip the extra rinse. When washing cloth diapers in hard water, you want to make sure your wash routine is working as it should.
If you have even moderately hard water over 60 ppmyou want to avoid doing additional rinses. Switch to a powder detergent. Powder detergents contain more built in water softening agents than liquid detergents, so it will give you more water softening power.
You can skip the water softener with Tide Original powder as long as your water tests at ppm or below for total hardness.
If you need a hand choosing a detergent for your cloth diapers, you can find some tips HERE. Use Borax. Until now, there were two options for water softening in Canada.Evap-Fresh is a ready-to-use, non-abrasive, one-step cleaner and disinfectant for evaporator coils in small air conditioners, commercial air handling equipment, HVAC cooling coils and refrigeration equipment.

Coil Gun. Louis, MO We'd love to hear from you. Please Confirm Click the box to submit.Soil is a mixture of mineral matter, organic material, air and water.
The mineral portion of soil is made up of particles which vary in size from stones to powder.
Mechanical Analysis of Soils "The Jar Test"
These particles are called soil separates. The relative proportions of these different sized particles determine a soils texture see figure. Fine textured soils have a high percentage of clay and are very sticky when wet and hard when dry.
The term heavy soil was coined a long time ago when people found clay soils very difficult heavy to plow. Coarse textured soils have a high percentage of sand and are loose and friable.
Coarse textured soils are not sticky when wet and are easy to plow, hence the term light soil texture was coined. Texture is an important characteristic of soil and affects water holding capacity, drainage properties, root development and more. Because texture has a great affect on water movement through a soil, it can also affect the rate at which pesticides and nutrients move through the soil. Soil particles, such as clay, can also bind up certain pesticides causing differences in pesticide activity on soils with different soil textures.
In the laboratory there are several different methods used for determining soil texture. The most common method for determining soil texture is the hydrometer method.
In this method the soil particles are dispersed with a sodium metaphosphate calgon and then agitated. After dispersion, the amount of each particle group sand, silt, clay are determined by using a hydrometer see picture. The hydrometer measures the amount of particles in suspension.
The principal of Stokes law, which states that particles will fall out of suspension at different rates over time, based on particle size, is used to determine the amount of each particle size present in a soil.
The amount of each particle fraction, sand, silt and clay, determines the soil texture. There are other methods of determining soil texture. The pipet method is used when the quantity of a sample is too small to be analyzed by the hydrometer method. The pipet method also uses particle settling rate to determine the percentage of sand, silt and clay in each soil sample.
There is also a European soil texture classification system that is different than the USDA classification system. In the European method, hydrometer measurements are take at different time intervals from the USDA method. The classification of soil texture categories and the texture names for the European classification system are also different that the USDA method.

In the past I have always made my despersing agent using 40 g of sodium hexametaphosphate per liter of distilled water as stated in ASTM D I have recently started working for a company that uses Calgon as the dispesing agent.
I know that hexamataphosphate is the active ingredient in Calgon. What I would like to know and can not find is: Does the calgon have to be diluted into a solution? If so, to what ratios. Hi Kev, Calgon is sodium hexametaphosphate that has been chemically and mechanically altered to make it instantly water soluble.
CAN it be used to replace sodium hexametaphosphate solution as a laboratory reagent? Well, in all likelyhood, yes it probably can. If the procedures are flawed then you can attempt to get them changed.
But until they are changed you should just keep following those procedures. Here in Australia, we use a stock solution of 33g of sodium hexametaphosphate and 7g of sodium carbonate to 1 litre of water. The solution has a use by date of 1 month. We then toss it out and mix up a new brew. Cheers Michael. The laboratory I was involved with used Calgon regularly, until the change was discovered. You question could more properly be addressed by an analytical laboratory; while I suspect Calgon wants to maintain their mixture a secret, you might contact them as well.
It seems like decades since I've thought of the Calgon v. I'd like to see a comparative study just to see just how much difference there'd be in the results. I'm not trying to argue with the sound wisdom of others suggesting that you use actual sodium-hex.
I'm just wondering. I know in undergrad labs 10 years ago-ishwe used Calgon, and to be perfectly honest, since I haven't done any dispersion tests since, I thought people still used Calgon.
Hi to all, just to expand a little, As Fattdad said, I would like to see some comparitve testing done.
