Progress 01/01/22 to 12/31/22
Outputs Target Audience:During this period, we reached out to students, researchers, and state/federal agencies through virtual workshops, meetings, and presentations. Changes/Problems:It is well known that all of us are affected by different waves of COVID-19. Even in Jan 2022, we had a large breakout of COVID-19. As a result, we may have limited opportunities to work with students, other researchers, and create face-to-face training and workshops. We will try our best to withstand COVID-19 or other challenges. What opportunities for training and professional development has the project provided?Two postdoctoral researchers and six graduate students were trained in installing automated soil CO2 sensors and taking measurements using those sensors at the field scale. Three undergraduate students were trained to measure CH4 and CO2 using a Tracegas analyzer. Students took soil and water samples from the field and analyzed the soil and water physical and chemical properties. The students were trained and able to collect water samples for water quality studies. Students were trained to install suction cups at all plots on the research farm. Students were trained to develop research plots and plant sorghum and corn on the PVAMU research farm. Students also had opportunities to assist in downloading climatic data across Texas. In addition, students will have opportunities to present their research findings at local and regional conferences. How have the results been disseminated to communities of interest?We presented our results at six national and international conferences through poster and oral presentations and peer-reviewed publications. Students also had opportunities to present some of the results at research symposiums. One article has been published in a peer-reviewed journal. One manuscript is under review, whereas one manuscript is ready for submission in a peer-reviewed journal. However, because of the ongoing pandemic, we could not disseminate our results to the farmers and ranchers (face-to-face) as we originally planned. What do you plan to do during the next reporting period to accomplish the goals?We have completed planting two major crops, corn and sorghum, grown in Texas. We plan to grow cotton next season, most likely in Spring 2023. The soil moisture sensors and CO2 sensors will be re-installed to monitor soil moisture, temperature, conductivity, and carbon emission. In addition, soil suction cups will be re-installed shortly on the research farm. We will set up a hydrologic model at Sorghum, Corn and Cotton dominated catchments of the Brazos watershed. We also plan to develop the plant hardiness zone maps next year. We will quantify the impact of climate change on crop water requirements for cotton this year. Next year, the impact of climate change scenarios and climate extreme events on different crops will be evaluated. The response of cotton to different Irrigation and fertilizer application rates will be studied next spring season (2023). Since the impact of COVID-19 has been reduced recently, we plan to organize workshops and farm demonstrations to enhance extension and outreach activities this year.
Impacts What was accomplished under these goals?
Goal 1: Generating projected daily climate forcing data using Global Circulation Model simulations and statistical downscaling techniques. The change in climate is projected until 2099. To address this goal, different gridded precipitation datasets were evaluated to develop reliable climate information and characterize the historical climate at the Bosque watershed of the Brazos River Basin. Goal 2: We have developed a research testbed on Prairie View A&M University's (PVAMU) research farm. We developed twenty-seven plots around the existing eddy covariance (EC) flux tower to monitor actual carbon emission and/or uptake. We planted corn; however, we could not accomplish anything due to the ongoing COVID-19 pandemic, which started at the beginning of 2020. On the other hand, we successfully planted sorghum and corn in 2021 and 2022, respectively. Goal 3: The Soil Water Assessment Tool (SWAT) model has been set up and calibrated at one of the Bosque watersheds of the Brazos River Basin. The SWAT model was used to evaluate the gridded precipitation datasets in the Bosque watershed of the Brazos River Basin. The SWAT model was also used to evaluate the change in different hydrological signatures and water balance components under historical and future climate change scenarios. The application of the SWAT model for water quality, crop water requirement, and crop nutrient assessment under changing climate conditions is still to accomplish. Goal 4: We are developing optimal climate adaptation measures for crop water requirement, crop yield, and soil and water quality and training underserved undergraduate and graduate students. However, we still need to work to accomplish this goal.

Progress 01/01/20 to 12/31/20
Outputs Target Audience:During this period, we reached to students, and researchers, and state/federal agencies through virtual workshops, meetings, and presentations. Changes/Problems:It is well known that all of us got severely impacted by COVID-19 in 2020. Even now, in March 2021, we still have to maintain social distancing, and we have limited opportunities to work with students and other researchers face-to-face. In addition, the project's postdoctoral researcher left us because he got a better opportunity elsewhere. On the other hand, we could not recruit another postdoctoral researcher because of the ongoing pandemic. However, we are trying our best to get everything on track and accomplish the proposed research goals as soon as possible. What opportunities for training and professional development has the project provided?One postdoctoral researcher and three graduate students were trained on how to install methane sensors, automated soil CO2 sensors, and how to take measurements using those sensors at the field scale. Students were also trained to develop research plots, and plant corn on the PVAMU research farms. Students also had opportunities to assist in downloading climatic data across Texas. How have the results been disseminated to communities of interest?We have presented our results at two different national and international conferences through oral presentations, and publication. Students also had opportunities to present some of the results at research symposiums. However, we could not disseminate our results to the farmers and ranchers as we originally planned because of the ongoing pandemic. What do you plan to do during the next reporting period to accomplish the goals?Next, we plan to plant either Sorghum or Corn on the research testbed by summer and install soil moisture sensors, water quality monitoring instruments, soil CO2 sensors to monitor carbon, water quality, soil moisture, and other parameters. We will set up a hydrologic model at several cropland-dominated catchments of the Brazos watershed. We also plan to develop the plant hardiness zone maps next year. We also plan to quantify the impact of climate change on crop water requirements either for Sorghum or Corn next year. If we get rid of this pandemic, we also plan to organize a workshop and farm demonstration to enhance extension and outreach activities next year.

Outputs Target Audience:During this period, we reached to students, researchers and limited resources farmers and growers. We also reached state and federal agencies through coordinating meetings and workshops and let them know about our ongoing project and potential benefits after the completion. In addition, we also reached to county agents and extension specialist to inform them about our ongoing project. Changes/Problems:
