About Dr. Decock
Charlotte Decock earned a B.Sc. and M.Sc. in Environmental Engineering from Ghent University in Belgium, and a Ph.D. in Soils and Biogeochemistry at the university of California, Davis. Her doctoral research focused on nitrogen cycling and emissions of the potent greenhouse gas nitrous oxide (N2O) from agroecosystems in a changing global environment. She conducted consulting work on the quantification of greenhouse gas emissions reductions from agriculture for a California-based carbon offset program, and contributed to various reviews and meta-studies related to the mitigation of N2O emissions from soil. As a postdoctoral researcher at ETH Zurich in Switzerland, she studied effects of plant roots on carbon and nitrogen cycling, with the aim of identifying root traits that could improve soil health and nutrient use efficiency. She also led and contributed to projects on the effect of water and nutrient management on soil fertility, nitrate leaching, and greenhouse gas emissions in rice cropping systems in Northern Italy and India. The project in India placed explicit emphasis on the farmers’ perception and feasibility of proposed management practices at the farm scale, through farmers’ surveys and participatory research. The role and importance of farmers’ participation in agricultural research and extension was also a crucial focus of the course entitled ‘Agroecologists without Borders’, which she taught at ETH Zurich from 2013-2016.
At Cal Poly, Charlotte Decock teaches Soil Health and Plant Nutrition (SS 221), Soil-Plant Relationships (SS 322) and Introductory Soil Science (SS 121). SS 221 covers many of the learning objectives of the Western Region Certified Crop Advisors (CCA) program, preparing interested students for the professional certification. Charlotte Decock’s research at Cal Poly focuses on soil health and nutrient cycling in California specialty crops, with special attention to strawberry and leafy green cultivation. She is interested in the evaluation of novel indicators for the assessments of soil health and nutrient availability in California cropping systems. Her work on carbon and nutrient cycling aims to contribute to the development and assessment of soil and nutrient management practices that protect water and air resources, while maintaining agronomic productivity and economic viability.
Student comments about the teacher:
The strengths of the instructor is her knowledge and enthusiasm about the course material.
It was Dr. Decock’s first quarter teaching but she was very friendly, clearly enthusiastic and knowledgeable about the subject matter.
A strength of the instructor was answering questions in a clear manner and further explaining if needed.
In lab, it was nice to learn hands on.
The [course] material was very interesting and applicable to field production of crops.
1 Teaching quality rating is based on student teaching evaluations completed by Cal Poly students. A cumulative grand average for all courses taught over the last two years is calculated from responses to the student evaluation question, "Overall, this instructor was educationally effective" that ranges on a scale from 1=Strongly disagree to 5=Strongly agree.
