Texture by Feel

You can analyze the texture of soil with just your hands. This helps with classifying the kind of soil you are observing. There are 3 types of soil structures: sand, silt and clay.

How to analyse soil texture by feel

gallery img01First, take a soil sample. For this, you need a hand shovel with which you can excavate the soil down to 10 cm.

gallery img02Afterwards it is necessary to prepare your sample. You should remove plants, roots and stones from the soil sample. If the soil is too dry, it must be sprayed with water. If it is too wet, dry soil must be added.

Spiders are a class of the arthropods. Currently there are about 100,000 known species. The body of a spider is subdivided into two parts (front body and back body). It has 4 pairs of legs and further extremities, like poison claws, scissors, feelers or mouth parts.

Spring tails have six feet and reach a length of 0.1 mm to 17 mm. They are mainly found in humus layers, not too dry soils down to a few metres and in rotting plant material.

Earthworms live in the soil and are cylindrically structured worms. Currently 54 known species live in Austria. Their average lifetime is between three and eight years. The best known species in Austria is the common earthworm (Lumbricus terrestris). The common earthworm becomes 9 cm to 30 cm long.

Currently there are over 350,000 known species in 179 families. This makes beetles the largest species in the insect family. The body shape of them is very diverse and varies from long, slender to very short species. Furthermore, there are flat to strongly spherically shaped bodies. The body shape varies from species to species and shows the adaptation to the way of life of the individual species.

The body of ants is divided into three parts (head, chest and abdomen). In addition, they have three pairs of legs and some of them have two pairs of wings. There are more than 13,000 known species. Ants live in so-called insect states, which are always divided into at least three castes, fertile females (queens), fertile males and workers.

Isopods belong to the class of higher crustaceans. They can grow from 0.3 mm to almost 50 cm in size. They are flattened from the back to the belly. They have seven pairs of legs. The gills sit at the rear legs. However, different species have different levels of adaptation to life on land. Therefore, there are also species with other respiratory organs such as tracheas or lungs besides gill breathing.

The Thousand leggers are a subline of the arthropods. They comprise exclusively land living species with a two- or three-digit number of legs. Thousand leggers have a body divided into two parts. They have a head capsule consisting of several segments and a divided trunk with at least four leg supporting segments.

Snails belong to the mollusc tribe. The body size of the snails varies from less than 0.5 mm to over 90 cm. The body of a snail consists of head and foot as well as the back lying visceral sac, which is protected by the tissue layer of the coat. Cells in the coat form a hard shell, which resembles other mollusc shells in the basic structure, which is usually asymmetrically twisted to one side of the body.
