The use of biodegradable capsules, made of cardboard, increases the chances of germination of seeds from three tree species typical of the Cerrado region: barro, anjeco branco and monkfish. These species are culturally, nutritionally, and ecologically important to the biome, and novelty could advance restoration programs for degraded areas.
The research involving biodegradable cardboard capsules was developed by researchers from the Federal Universities of Jatay (UFJ), in Goiás, and Rondonopolis (UFR), in Mato Grosso. The species it covers are specific to the Cerrado region. Barrow produces oilseeds known as Barrow nuts which are rich in nutrients. White angelfish and monkfish contain parts used in medicinal preparations, such as infusions.
The experiments were carried out over a period of four months in a greenhouse at the Mineros University Center in Goiânia, to test the differences between the use of capsules and direct seeding. In each sample, the team deposited two seeds of each type. In the case of Barrow, for example, the germination rate with the capsule was close to 100%, while with direct sowing it was only 15%. The same thing happened with the white Angica fish, which had a protection rate of 42% compared to 21% with direct cultivation, and with monkfish, which recorded a protection rate of 12% compared to 8%.
The capsule, developed from cardboard used for egg packaging, ensures protection of the seeds in the soil from herbivores, as well as increased moisture retention, ensuring thermal comfort of the seeds. Direct sowing can only be successful when various factors, such as the use of appropriate agricultural techniques and practices, improve seed germination
As next steps, the researchers intend to evaluate the growth and survival of newly germinated plants in the field, as well as conduct a detailed analysis of the financial costs involved. They also intend to implement the methodology in hard-to-reach areas to monitor plant growth and evaluate the effectiveness of the process in other environmental conditions.
