摘要：
The present invention refers to the use of biological compounds containing beneficial microorganisms which coexist as symbionts with the roots of native or wild plants and crops, which provide nutrients such as nitrogen and phosphorus, but also reduce the effect of soil phytopathogens that attack the roots of plants, since they may act as antagonists, this is the case of the Azospirillum brasilense bacteria and the Glomus intraradices fungus, which may be applied or inoculated in the seeds, by them selves or mixed with solutions of potassium chloride (KCL). The invention also refers to the use of hydrosoluble extracts of Larrea tridentata, which act as seed-germination and seedling-elongation stimulants, also increasing the dry biomass in seedlings of different agricultural crops. The application method is also included, which is based on soaking the seeds in an aqueous solution of the L tridentata extracts for a predetermined time before germination and development of the seedling. The process for extracting the L. tridentata resin with different solvents, as well as the process for turning the same into a soluble resin, is described in the process Patent for the production of water- soluble or -dispersible Larrea resin, which has the application number 9810828. The Larrea tridentata extracts are hydrosoluble powders which may be used by themselves, mixed therebetween, or mixed with other agrochemical products such as other growth regulators, pesticides, fertilisers or nutrients, for preparing aqueous solutions at different concentrations, which will depend on the type of seed and the desired results.La presente invención se refiere al uso de uso de compuestos biológicos conteniendo microorganismos benéficos que coexisten como simbiontes con las raíces de plantas nativas o silvestres y cultivos agrícolas, los cuales aportan nutrimentos como nitrógeno y fosforo, pero además pueden reducir el efecto de fitopatógenos del suelo que atacan las raíces de las plantas, ya
