landscape students and the archeo park

a new quick follow-up of the work done to revamp the archeo park in V d’Ascq :

Our students were sent on a scientific mission :  apparently they were shown how to spit some saliva onto a small quantity of soil in their palm, so as to determine the presence of clay !

Experimenting, hey ?

Analyzing the soil and writing a list of plants

In order to make the inventory of plants in the archeological park, the students were divided into several groups to analyze the area.

Consequently our group studied a part which was grassland and which is used for welcoming group activities or special events.

Example of plants found in the grassland :

| Taraxacum officinale (dandelion) : yellow flowers, long green leaves. It lives in rich soils.

| Urtica dioïca (stinging nettle) : greenish fowers, quadrangular stalk, indented leaves. It indicates a polluted soil.

| Trifolium repens (clover) : small leaves with 3 folioles, a long petiole, white or pink flowers. It is a sign that the soil is rich in water.

| Carduus nutans (thistle) : purple flowers, prickly leaves. It reveals a compacted soil.

From these observations, we could state that the soil was rich in organic matter, and compacted. In addition, we noticed that the ground was swampy because there was a lot of water at the surface.

We conducted a proper soil analysis, with the taking of samples and the testing with different techniques : the eye, the taste, the ph test, and even the spitting in the hand !

We came to the conclusion that the soil was rich in clay and dry stilt.

  • interesting Céline as similar wildflowers/weeds grow in my area plus some others which tell me the soil is very acidic, my soil is peat which is organic matter and I have often thought there is a strong presence of silt as my garden is low on a hill and peat and soil are washed down, Frances
