TITLE:

Agronomic efficiency of coconut powder (cocos nucifera) associated with cultivated oyster waste (crassostrea sp.) as an agricultural substrate based on the analysis of two treatments carried out in a vegetation house.

KEY WORDS:

Shellfi sh waste, calcium carbonate, coconut dust, environmental sustainability and economicviability

PAGES: 90
BIG AREA: Engenharias
AREA: Engenharia Sanitária
SUMMARY:

Research over the last twenty years in Brazil has shown that the results for the use of coconutdust as a substrate for commercial seedling production have been appropriate, mainly due to itsavailability (abundance) and low cost. On the other hand, although the use of shellfi sh waste has beenproven to be eff ective as an agricultural corrective, its use as a product incorporated into an agriculturalsubstrate has not yet been carried out. Various studies have been carried out using coconut dust, whichhave provided clear evidence of the effi ciency of this raw material in the root growth phase, but this effi ciency is not maintained in the vegetative growth phase. It is hoped that the research in question willprovide results for the formulation of agricultural substrate, i.e. proposing a more effi cient proportionfor the use of coconut dust associated with shellfi sh waste (oyster dust), solving the problem of thevegetative growth phase in particular. If so, this will bring a technological innovation that aims toovercome, among other issues, the problem of soil fertility for the bean crop. In short, the study has agreat social impact because, by transforming waste into useful raw material for agriculture, it helps topreserve the environment, create jobs, improve agricultural production and promote more sustainableand innovative practices in the countryside. This directly benefi ts coastal communities and smallproducers, contributing to a more sustainable and just future.
