Tectopore increases soil organic matter
Soil organic matter originates from various elements such as plants, plant and animal residues and self-sustaining organisms. It consists of fresh matter or necromass and its low presence decreases soil fertility.
With more organic matter, water retention capacity increases, favours adequate porosity and, in general, improves soil quality, with positive results for crops.
This trial was carried out precisely because of the need to increase the percentage of organic matter in the soil of a farm with a perennial Hypericum crop, with plants of around seven years old on average.
We set out to evaluate the amount of organic matter that could be increased in comparison with the applied dose of Tectopore Pure per treatment, in order to establish the impact.
We tested three different doses in the same bed and each dose was evaluated in a space of one square metre (m2). Soil analysis was done at ten cm and twenty cm depth. As for the granulometry, it was similar in all of them and was done on the same block and bed of the farm.
In order to evaluate the increase in organic matter, we started with a soil analysis prior to the application of Tectopore Pure. In order to make a comparison, another analysis was carried out six months after the product was applied.
The behaviour of the micro-elements was also assessed, especially the behaviour of iron, due to the susceptibility of this crop to this micro-element.
Method of application
We cleaned a 3 squared meters surface of the bed to apply Tectopore Pure and divided the area into 3 equal parts. Using a container graduated in litres, we dosed the doses for the three treatments and proceeded to place the product on the surface of the bed until the area was completely covered. The Tectopore Pure was immediately watered to moisten it and then covered with the compost produced on the farm to cover the entire area of biochar.

Summary of microelements behaviour
(Before the test and 152 days after the second sample was taken)
In the microelements measured, it can be seen that the only ones with a higher level than the initial level are manganese and boron are manganese and boron. The concentration of the other micro-elements decreased.
