Resumen
One of the consequences of the use of agrochemicals is the loss of the natural composition of the soil, and the changes in its physicochemical characteristics. The present work of investigation, evaluates the behavior of a crop of Lactuca sativa L. var. Crispa L (Simpson crespa lettuce), being an organic culture technique that uses a microbial biopreparation (nitro fixer -AZOBAC), in a soil with nitrogen deficiencies. As a nutritional supplement, activated compost with efficient microorganisms (EM) will be used, evaluating: growth time, frequency of application of AZOBAC and yield of the crop. In the experimental development, 3 treatments will be carried out applying the AZOBAC nitro fixative at different frequencies (15, 20, 30 days) in the culture with the presence of a control. The statistical treatment and the evaluation of the variance between the data are carried out using the Duncan test.
