Dung and agri-food by-products reduce soil fatigue and increase yields by up to 46%, according to a thesis from the UPCT
A new thesis from the Polytechnic University of Cartagena (UPCT) has validated biosolarization based on organic amendments as a sustainable and effective tool against pathogens that attack the pepper under greenhouse, also achieving increases of up to 46% in crop yields And improving water infiltration and retention.
The research of the new Dr. Pedro Fernández Molina has tested for four years in experimental greenhouses to conclude that biosolarization from quality amendments and adapted doses is a technique capable of controlling edaphic pathogens without risks to the soil or to the environment.
Soil pathogens that compromise the viability and profitability of crops have proliferated in recent years favored by the monoculture of pepper under greenhouse in the Region of Cartagena and chemical agents, including bromine, now banned, have been used against them.
"As a sustainable alternative, biosolarization has disinfectant effects on pathogens and recovery and increase of soil fertility, increasing the productive capacity of the greenhouses," explains the author of the thesis, led by Alfredo Lacasa Plasencio and Santiago Larregla Palace.
Developed within the PhD program in Advanced Techniques in Agricultural and Food Research and Development (TAIDA) of the Polytechnic, the thesis has tested with sheep manure and chicken manure and byproducts of the agri-food industry, such as beet vinasse, Brassica carinata pellet, Rape cake and bagasse.
