The amount of wet that's in your soil tin greatly impact how well your plants grow. Luckily, there are many ways to measure soil wet, whether you're hoping to get a general thought or a more specific measurement.

1. i

   Stick your finger 1–2 inches (2.5–5.i cm) into the soil. If the soil feels dry out or if information technology falls off of your finger when yous remove it, the soil may be dry. If the soil feels moist or if the soil sticks to your finger, the soil may be moist.^[i]

2. two

   Identify dry soil by its light-colored, compacted appearance. If you're just trying to get a full general thought of how dry or moist your soil is, but accept a good look at it. If it'due south a lite color, such every bit tan, and/or is hard and compacted together, then your soil is nearly likely on the drier side. This may hateful that you demand to water your soil more.^[2]

   • Keep in mind that some soil naturally looks lighter, despite the amount of moisture in information technology. Familiarize yourself with how your specific type of soil typically looks before you lot assume that it'due south dry.

   Recognize moist soil by its muddy, mossy appearance. Soil that has a lot of moisture in it tends to be waterlogged and squishy. This is a good environment for growth, so you may also find that moist soil has moss and other greenery growing on its surface. If your soil looks similar this, then you may need to install an irrigation system to go along your plants from getting root rot.^[3]

4. 4

   Spot dry out soil by its inability to hold shape or stain. Pick up a handful of the soil. Shut the soil tightly in your hand and so open your hand dorsum upwardly. If the soil remains in a loose pile, then information technology may exist dry. Driblet the sand and brush the soil off of your palm. If your mitt looks relatively make clean, this is further proof that the soil is dry.^[4]

5. v

   Identify moist soil by its ability to stain and hold shape. If you shut the soil in your hand, open your manus back up, and the soil has stuck together and formed into a ball, and so information technology'southward likely moist. You may besides assume that the soil is moist if your paw is heavily stained after you've dropped the soil and brushed it off.^[5]

   Purchase a basic soil moisture probe. Go to your local hardware store and await for a soil moisture probe or a soil moisture meter. This is a tool that tin can apace and easily decide your soil'southward wet level when it's inserted into the ground. The prices of probes and meters vary based on type and adequacy.^[6]

   • You can expect to pay $x-20 USD for a moisture probe that has a traditional scale indicator and few other capabilities. If you want a traditional probe or meter that has multiple capabilities, it'll likely cost you closer to $fifty USD.
   • Digital probes and meters with few capabilities can cost every bit lilliputian as $30-xl USD, while more advanced ones that can decide other measurements can cost $50-200 USD or more.
   • Another capabilities that soil moisture probes and meters frequently have include measuring the pH value of the soil and determining soil temperature.

2. 2

   Push button the probe into the soil and read the results. Push the probe down into your soil and expect to come across the results. This should only take a couple of seconds. In one case the probe has effectively assessed the moisture level of the soil, a number should pop upwardly on the display area if y'all're using a digital probe. If y'all're using a traditional probe, y'all should run across the arrow move and stop at a specific number on the scale indicator. Read this number once it is displayed.^[seven]

   • If you're hoping to get an accurate idea of how much moisture there is in the soil that makes up a big area, accept a few more readings in unlike spots that are spread out within the expanse.
   • In the very least, examination your soil whatsoever time it looks and feels very dry or very wet. This way, you tin find out the exact moisture level and water or irrigate your soil accordingly.

3. three

   Identify dry soil past a number lower than 5. It's typically best to keep your soil effectually v. While different plants thrive in different levels of wet, 5 is a skilful middle ground where a multifariousness of plants can grow and flourish. If the probe displays a number lower than v, your soil is dry out. In this instance, consider watering your soil.^[8]

4. 4

   Spot moist soil past a number college than 5. You may find that the number displayed on your probe in greater than 5. This means that your soil is moist. While moist soil oftentimes encourages growth, information technology tin cause issues if information technology gets too waterlogged. Consider setting upward an irrigation system to help drain your soil.^[9]

   Endeavour the gravimetric method. To measure your soil wet using the gravimetric method, scoop upwards a small sample of it and use a small metric scale to counterbalance it. Put the sample on a blistering sheet and put information technology in your oven. Dry out the soil out in the oven by setting it to 221 °F (105 °C) for 24 hours. And so, weigh the sample again. The difference in the weight before and after drying the soil in the oven will reveal how much moisture is in the soil.

   • A smaller weight difference indicates dry soil while a larger weight deviation indicates moist soil.
   • Unlike types of soil can survive on different amounts of water. Nevertheless, the platonic balance for about soil types is 50% solids, 25% water, and 25% air.^[10]
   • To calculate the exact amount of water that makes up the soil sample, subtract the dry weight of the soil from the wet weight of the soil (in grams). Then, divide this total past the dry weight of the soil and multiply this total by 100. For example, if the sample weighs half dozen oz (170g) when wet and 5 oz (140g) when dry, so your sample is made up of 21.iv% water.

2. 2

   Use a tensiometer to decide the h2o tension. Tensiometers, which can be purchased online, are sealed, water-filled tubes that have a porous base of operations and a vacuum gauge top. Insert the device into the soil at the depth of your plants' roots and read the approximate at the pinnacle to find out how much water is available in the soil.^[11]

   • The price range for tensiometers is typically between about $seventy USD and $200 USD.
   • If your tensiometer determines that the water tension in the soil is ten centibars or lower, there is an excessive corporeality of moisture in the soil and you may demand to irrigate.
   • If your tensiometer determines that the water tension in the soil is between 60 and 80 centibars, your soil is probable too dry and needs to be watered.^[12]

3. 3

   Scatter neutrons in the soil to get specialized measurements. Insert a neutron probe to root level in order to besprinkle neutrons into the soil and detect how much hydrogen, and as a result how much h2o, is in the soil. While this may exist the about accurate way to measure soil moisture, neutron probes are very expensive, and typically price between $3,500 USD and $iv,500 USD.^[xiii]

Article Summary Ten

To measure soil wet generally, look at it and feel it. Stick a finger into the soil to feel for wet. Identify dry soil by its lite color, compacted appearance, and inability to hold shape or stain. Identify moist soil by its dirty, mossy appearance and its ability to hold shape and stain. To get a more precise measurement, become a soil moisture probe from your local hardware store and insert it into the ground. If it's above 5, then information technology's moist, and if it's beneath 5, then information technology'southward dry out. To larn about scientific ways of measuring soil moisture, such as by using the gravimetric method, read on!
