A soil profile is a 'cross section down through the soil'. It normally consists of a number of soil horizons. (layers). and plant relationships and the soil water balance. textural class can be determined using a soil textural .. (water not in direct contact with the soil); that is, it.

Third, clayey or fine-textured soil offers a sizable surface area because of the smallest size of clay particles. Thanks to this, this soil texture is the ideal type.

Clay easily absorbs water and has great capacity for holding water and nutrients.

All you need is the soil, a glass jar, and some water. First, put water in a jar. Then, place the soil you want to know the texture of.

Next, shake the jar of water and soil and let them settle. The gravel and sand particles will go down to the bottom of the jar first. This portion has the coarse-textured or sandy soil.

Soil texture and water quality

After marking this section, you should wait a couple of hours to let more of the soil settle down. The next layer you will see is the loamy or medium-textured soil. Lastly, wait for a day for everything else to settle down. By this time, the water should be clear and located at the top. The uppermost layer will contain the clayey or fine-textured soil.

By this time, you can simply check the percentage of each layer to determine the soil type. So, what do these have to do with water? Well, simply put, water absorption and retention are dependent on soil texture. Once the water goes into the soil, it has to rely on what we refer to as micropores to stay there.

At worst, this kind of soil will only hold two inches of water. With fine-textured soil, your soil can stay healthy for eight days after giving it four inches of water. Soil structure — this is the arrangement of soil particles, namely sand, silt and clay into a unit called aggregates. The aggregates can be friable or loose, or they may form uniform patterns.

These can give the soil its overall structure. The porosity of the soil depends on its structure and texture. For instance, fine soil has small but numerous pores compared to coarse soil. Coarse soil has large pores but fewer pores. Additionally, small pores can hold water tighter.

Water holding capacity — ability of the soil to hold water. This information is useful for crop selection and irrigation scheduling. Depending on the soil texture, their water holding capacity in inches per foot of soil are as follows: Coarse sand — 0.

Soil texture is important because it controls how well the soil can hold water and absorb it. The micropores affect the water holding capacity of the soil.

Imagine putting marbles on a table and pouring water over it. Now, imagine pouring water through a fine sponge. It will absorb and hold water until its pores are filled. In summary, the ability of the soil to absorb and retain water is hugely dependent on its texture. If the soil is coarse because of its large particle, there will not be enough surface area that can hold much water. At most, sandy or coarse soil can only hold up to two inches of water.

In contrast, the finer the soil is, the better is its water absorption and retention capacity. Fine-textured soil can hold four inches of water. It is important to note though that while clay has the highest capacity to hold water, its fine micropores hold the water very tightly that the plants will have difficulty in extracting it.

Silt and loamy soil, on the other hand, can hold a significant amount of water which are readily available for most plants to use.
