The use of carbon isotope ratios to evaluate legume contribution to soil enhancement in tropical pastures por Rao, Idupulapati M., Ayarza, Miguel Angel, Thomas, Richard J.

“…Improvements in soil fertility resulting from the soil organic carbon originated from legume residues were measured as increased potential rates of nitrogen mineralization and increased yields of rice in a subsequent crop after the grass + legume pasture compared with the grass-only pasture. …”

Soil depth and physicochemical properties influence microbial dynamics in the rhizosphere of two peruvian superfood trees, cherimoya and lucuma, as shown by PacBio-HiFi sequencing por Estrada Cañari, Richard, Porras Valencia, Angie Tatiana, Romero Avila, Yolanda Madelein, Pérez Porras, Wendy Elizabeth, Vilcara Cárdenas, Edgardo Arturo, Cruz Luis, Juancarlos Alejandro, Arbizu Berrocal, Carlos Irvin

“…We analyzed the microbial community at three depths (3 cm, 12 cm, and 30 cm) in the native fruit trees Annona cherimola (cherimoya) and Pouteria lucuma (lucuma), which provide fruits in vitamins, minerals, and antioxidants. We used PacBio-HiFi, a long-read high-throughput sequencing to explore the composition, diversity and putative functionality of rhizosphere bacterial communities at different soil depths. …”
