    Manejo agroecológico de la fertilidad del suelo en el cultivo de mora (Rubus glaucus)
    (2023-03) Sánchez Camino, Alejandro Xavier; Mera Andrade, Rafael Isaías
    The present research work was carried out with the objective of determining the nutrient content and the presence of microorganisms during agroecological soil management in a 6-month-old blackberry crop (Rubus glaucus). The treatments studied were: mulching with plant residues, crop associated with legumes and the control. The results obtained showed that the treatment associated with legumes (AL) showed a higher content of the elements: N-nitrates, N-ammonium, P-water soluble, K-water soluble, Ca, B, Zn. A stable MO. result was obtained and a lower content of the elements: P, K, Mg, S, Mn, Fe, Cu. While the treatment mulched with pruning residues showed a higher accumulation of K, Mg, S, Mn, Fe, it also maintained stable pH and EC values. And a lower content of the elements: N-NO3, N-NH4, P, P-H2O, K-H2O, Ca, B, Cu, Zn, and finally the control without mulching (SN) reported a higher content of the elements P and Cu, and, a lower content of Nnitrates, N-ammonium, total P, water-soluble P, total K, water-soluble K, Mg, S, Ca, B, Mn, Fe, Cu, Zn. In relation to the Hydrogen Potential (pH) was more unstable in the AL treatment with a difference of -0.69, followed by SN (control) with -0.67 and finally BRF (mulching) which was shown to be the most stable with -0.13 difference. Regarding the Electrical Conductivity (EC), it can be seen that the treatment association with legumes (AL) has a difference of -1.22 mSiem/cm, the control treatment (SN) has -0.79 mSiem/cm and the mulching treatment with pruning remains is more stable with a value of -0.30 mSiem/cm. As for Organic matter (OM), the treatment of association with legumes (AL) obtained 7.10 %, making it the treatment that consumed the least percentage of OM. The control (SN) reports a difference of 7.13% of OM and finally the mulching treatment with pruning residues (BRF) has 10.23% of OM. Regarding the presence of microbial populations, the wide range of fungi and bacteria can be appreciated, these maintained a similar count on day 1 and day 90 in all treatments; however, the appearance of some pathogens could be appreciated in the treatments where they did not exist initially, Cladosporium herbarum, Fusarium oxysporum, Pythium oligandrum, Pythium ultimun.
