Etiketle | Özet: | Soil contamination due to the heavy metal Zinc is related to poor agricultural practices that directly affect plant growth. The use of alternatives such as phytoextraction due to its competitive advantages in terms of costs to control erosion and arbuscular mycorrhizae due to its great importance in the root zone where the fungus develops a network that can explore the soil, capture nutrients and water. for the plant they are strategies to remediate the soil. In this project, we sought to optimize the phytoextraction of Zinc in contaminated soils using the inoculation of arbuscular mycorrhizae where the effectiveness of different strains was evaluated and their capacity to increase the accumulation of zinc in plants and reduce its concentration in the soil by means of the sieving and wet decanting method, subsequently the quantification of zinc in the soil samples from the treatments was determined in the INIAP soil, plant tissue and water laboratory. In the five soil samples selected from the cocoa crop, 16 species with low density were identified, among which Acaulosporaceae bireticulata and Rhizophage intraradices stand out. Regarding the agronomic variables of rice (o.sativa), germinated seeds and stem diameter did not present significant statistical differences. However, the height of the plant, the number of leaves revealed a statistical difference. Regarding the effect of zinc in the soil samples, an analysis of variance does not show statistical significance. In conclusion, given that solid and spore-inoculated treatments showed superior results, it is necessary to consider systematic inoculation to improve agronomic responses. |
