On Tuesday, November 17, researchers from INTA Argentina and the Faculty of Agronomy of the University of Buenos Aires made a trip to Chascomús to collect data and take soil samples in the framework of two doctoral work.
During the trip, lots with hydro-halomorphic soils were visited, under production of pastures with and without the practice of management to promote Lotus tenuis and natural grasslands. Cattle urine events were simulated to measure the area deposited by this type of excreta and thus perform surface N2O emissions calculations. Lots were also selected to carry out pits (observation pits of approximately 1 m deep) to evaluate the morphological characteristics of the soils under study and to carry out samplings that allow obtaining carbon stock values.
In addition, potential lots were selected for studies of biological nitrogen fixation by Lotus tenuis; for which, in addition to analyzing the external characteristics, samples were taken to characterize the soils according to their pH and electrical conductivity.
