It is important to carry out a soil texture analysis for any garden that you want to plant in.
This is because of the impact that different soil texture characteristics can have on your ability to grow certain plants.
Soils breakdown into 3 groups – clays, loams and sands. But there are further subdivisions within each of those groups and it is useful to know where your soil texture fits within these sub-divisions, so that you can plan any necessary soil improvement efforts more precisely.
It is possible to take a soil sample and send it off for professional analysis and this is probably what you would do if you were looking to plant commercially.
But there is a simple way for the home gardener to to undertake a soil texture analysis and that is what I explain how to do below.
By the way, if you have children, whether they are yet interested in gardening or not, this may well be something that they might like to do with you since essentially it involves playing around with mud.
These are the steps you need to take:
I’ve included these instructions and the table below in a handy, downloadable .pdf file, so that you can print them out and take them with you as you do the test. Click here to get the download.
|Characteristics of Sample||Soil Texture Class|
|Cannot be moulded, will not stick together, no ribbon created, grains of sand stick to fingers.||Sand|
|Creates a fragile ball that just about holds together, leaves fingers discoloured, produces a short (5 mm, 0.2 inches) ribbon that easily breaks.||Loamy Sand|
|A fragile ball, sticky and with many grains of sand sticking to the fingers, leaves fingers stained with clay, ribbon of 5 to 15 mm (0.2 to 0.6 inches).||Clayey Sand|
|Forms a ball that just bears handling, grains of sand can be seen and felt, produces a ribbon 15 to 25 mm long (0.6 to 1 inch).||Sandy loam|
|As for Sandy Loam, but individual grains of sand cannot be seen only felt. Ribbon of 15 to 25 mm (0.6 to 1 inch).||Fine Sandy Loam|
|Creates a coherent ball with a spongy feel but no sandiness or silkiness. Forms a ribbon about 25 mm long (1 inch).||Loam|
|Forms a coherent ball although somewhat crumbly, smooth and silky to the touch. Forms a ribbon about 25 mm long (1 inch).||Silty Loam|
|Creates a very coherent ball with sand grains that can be felt. Forms a ribbon of 25 to 40 mm (1 to 1.5 inches).||Sandy Clay Loam|
|Forms a coherent spongy ball with a plastic, smooth feel. Will form a ribbon 40 to 50 mm long (1 to 1.5 inches).||Clay Loam|
|Creates a plastic feeling ball, but sand grains can be felt, seen and heard. Forms a ribbon 50 to 75 mm long (2 to 3 inches).||Sandy Clay|
|Creates a smooth ball with a plastic feel, some resistance to manipulation between thumb and forefinger. Forms a ribbon 50 to 75 mm long (2 to 3 inches).||Light Clay|
|Create a smooth plastic ball which feels like plasticine, can easily be moulded, resistance to manipulation between thumb and forefinger. Forms a ribbon and 75 mm or more long (3 inches, plus).||Medium Clay|
|Smooth plastic ball like stiff plasticine. Can easily be moulded. Strong resistance to ribbonning. Forms a ribbon at least 75 mm long (2 inches).||Heavy Clay|
