"4 PER 1000" SOIL CARBON SCIENCE WEBINAR SERIES #4: Can Increasing SOC Boost Crop Productivity?

Can Increasing Soil Organic Carbon Boost Crop Productivity?
In this webinar, we delve into the role of soil organic carbon sequestration in combating climate change and enhancing crop production.
Understanding the interplay between soil health and crop productivity is highly relevant as we face climate change and food security challenges. Dominic Woolf from Cornell University will share his latest findings from analysing more than 10,000 controlled field trials extrapolated to the global scale. He will discuss the effectiveness of soil organic carbon sequestration compared to nitrogen fertilization in improving crop yields, especially under optimized soil management. Mauricio Cherubin from the University of Sao Paulo will draw from studies in tropical regions on implementing soil carbon management techniques, resulting in improved crop productivity and livelihood. We will discuss the potential increase in global crop production by optimising soil carbon levels and opportunities to use technologies and practices to achieve multiple benefits.
Moderated by Budiman Minasny, The University of Sydney, "4 per 1000" Science and Technical Committee.
Speakers:
Beverley Henry, an Adjunct Associate Professor in the School of Biology and Environmental Science, Queensland University of Technology, Australia. Her research focuses on climate change and the land sector, including managing emissions from vegetation, soils and livestock production, and MRV systems for carbon offsets in agriculture and forestry.
Dominic Woolf, a Senior Research Associate in the School of Integrative Plant Science Soil and Crop Sciences Section, Cornell University. His research focuses on addressing the challenge of removing atmospheric carbon dioxide. Utilizing quantitative modelling, he evaluates the efficacy of strategies such as soil carbon sequestration, land restoration, and sustainable management practices. His work informs policy decisions by assessing economic and environmental trade-offs.
Maurício Roberto Cherubin, a professor at University of São Paulo (USP) in Brazil, is an agronomist with extensive research experience at leading institutions, including USDA and CENA/USP, specializing in soil science, plant nutrition, and environmental biogeochemistry. He established and leads the Soil Health & Management Research Group (SOHMA) at ESALQ/USP, concentrating on land use, soil management, soil health, carbon sequestration, nature-based solutions, and ecosystem services. He is the deputy general coordinator and research director of the newly established Center for Carbon Research in Tropical Agriculture.

Thanks for throwing light on this complex subject. As Prof. Cherubin emphasized, increasing soil organic content is not an option, it is a necessity. Great webinar! Looking forward to next one. #SaveSoil

Impressive research effort clearly presented, thank you and well done! Nevertheless, is it fair to talk 1h on soil carbon without mentioning living soil/soil life: a KEY actor in the soil carbon to yield system?? We mix carbon added in (bio)char and organic carbon input (biomass): 2 very different forms of carbons with very different roles... One habitat for microorganisms and ion exchange surface, the other food for soil microorganisms! Is it fair to look at the role of soil C levels on yield in systems with external/direct nutrient input given to the crop, bypassing therefore the need for plant-microorgnism exchanges, while one of the major role of soil C is to feed soil food web that, in turn, should feed the plant/give it access to all the required nutrient, build soil structure (and water retention as shown indeed)? Or am I miss understanding what I thought to be The major role of soil C (i.e.life along with water and nutrient retention)

Will you be bringing Dr walter jehne into your panel discussion. He is lovely to listen to.

[@saqlainkazmi-kp1mp]

Will you be making any discussion or analysis on micro forests (made on miyawaki principle)

[@slytherinda4669]

is there an established method for measuring SOC for soils? There are seemingly countless ways to measure SOC and over 15 different recognized forms/terms for SOC in soil science and I am trying to find out which form and which method (solid vs liquid combustion) is best for determining SOC in soil. I am currently using a liquid combustion indirect method where we determine total carbon and total inorganic carbon and subtract the two to arrive at total organic carbon. Thank yall!

Well done please

Please ensure the volume of sound is adequate next time you make videos. You all must be listening it on iPhones if at all. We have to listen to this on our cheap Android mobile, while driving. But the current volume demands that we keep holding it near my ear to listen or attach separate Bluetooth speakers. So please buy some good mics
