Seed card Vazio S/A: planting report – Vazio S/A

Projeto Tzedaká made Vazio S/A seed cards with the help of an agronomist. We attached bellow the planting report of Tzedaká. The cards can be ordered on info@vazio.com.br

OBJECTIVE

This study aims to monitor the germination of plants from Brazilian flora (…).

PRODUCTION

We produce handmade paper based on the pulp produced in the recycling of white scraps, dyed or not, with alkaline pigments for paper. On the still wet leave, seeds of Tingui do cerrado, cecropia, ficus, and tibouchina are distributed. A paper “sandwich” is formed on the seeds and a thin layer of natural sisal fiber paper is placed. It is whitened with hydrogen peroxide, completely free of chlorine and other chemical components.

(…) Forests, which are the main natural source of carbon on Earth’s surface, can absorb the emissions of carbon dioxide like a sponge. That is why investing on them is essential. Forests in Europe and North America are already fulfilling this role, draining significant amounts of gas. This phenomenon happens for two reasons: new forests are being planted and those that are in warmer areas, richer in carbon dioxide, grow faster. As they grow up, trees absorb the gas to grow leaves and branches.

PLANTING

Monitoring the experiment – the germination test:

07/31/2008
Jardinière # 1
We have planted two leaves, 10 x 14 cm, with the four types of seeds randomly placed.

Jardinière # 2
We have sown the species in specific areas in the jardinière, aiming to identify each plant after germination. Each type of seed was planted in a specific area because they have been randomly placed in the leave and it makes it difficult to identify each germinated species.

Forms of planting:
The jardinières have been prepared with layers of stones and earth. This earth is bought at the market, and it is already prepared to plant flowers and vegetables. The leaves of seeds were planted and covered with approximately 03 millimetres of soil. In the second jardinière, 01-centimetre deep furrows were made, from them the seeds were sown and covered with earth. Then it was covered with 01 centimetre of ground sugarcane bagasse, to keep moisture and cool temperature at the surface and watered in abundance. It could have been covered with grass, leaves, cotton, etc. When using materials such as non-chopped grass or cloth, these must be removed when the first seeds start germinating.

The coverage must have a thickness that does not prevent the passage and growth of the seedlings. It can be left in the jardinière, as it can be used for protection or vegetable manure. The earth has to be watered everyday, but not too much.

MONITORING

Until August 07 2008 no signs of germination appeared. On October 11 2008, all seeds germinated, as it can be seen in the photos below. The preparation of the land is very important, being the best substrate that found on the surface of flowerbeds where many different fall leaves, besides the need for constant moisture.

We are going to look into other seeds of trees or shrubs that can also do the job of offsetting greenhouse gases, but ones that germinate more easily.
