Teaching (75%) 1. Teaching Philosophy I consider myself as a life-long learner because learning is an ongoing process. As a teacher, I believe in having various roles in and out of the classroom setting. As an abstract learner myself, the traditional lecture format has served me well, however, as a teacher I recognize that there are many types of learning style in the classroom. I strive to use a variety of learning techniques in my courses, such as problem-based learning, hands-on activities, online lessons, small group activities to ensure that all learning style are accommodated. The problem-based technique is valuable to most learners especially as a backward design because it links the practice to the principles and makes it relevant for the learners. I believe that this approach integrates concepts rather than segregating concepts because it enhances the tasking, reflection, and conceptualization processes of the learning cycle. I also believe that a well-designed problem-based teaching can excite students about science, especially if students develop their own hypothesis, test their own hypothesis, and answer their hypothesis. “Tell me and I forget. Show me and I remember. Involve me and I understand.”

Chinese proverb You can teach a student a lesson for a day; but if you can teach him to learn by creating curiosity, he will continue the learning process as long as he lives. Clay P. Bedford

Successful teaching is not just measured by student-teacher evaluations, teaching techniques, or likeability by students, but it is reflected when learners apply concepts and/or principles and skills in their personal and professional lives. Finally, as a teacher, I take the responsibility of setting a classroom atmosphere filled with respectful treatment of each other, integrity, and confidentiality. I am especially devoted to helping learners enhance their professional development. The lasting measure of good teaching is what the individual student learns and carries away.

(1991-1992) 3. Current Teaching Activity Developing soil science online lessons for applications in various earth and environmental science disciplines; assessment/evaluation of technology use in teaching on student learning. a. Soil Resources AGRO153- Team taught with Tim Kettler (50% contribution)

6 semesters, 2000 – present, (n=69 – 88) Soil Resources 153 is an introductory service course required for Agronomy and several other majors of CASNR. The student enrollment in Soil Resources 153 is highly diverse in class level, background, and major areas. I especially focus my efforts in this service course because for most enrolled in the course, it is the only course in soil science they would ever have to take during their college years. One of the primary goals of the course is to emphasize soil as a critical resource for food and fiber production, pollution control, and biodiversity by linking principles to the application. With support from the course lecturer, Tim Kettler, I have


6

been actively working for the last 5 years not only to fit the course into my own educational philosophy but more importantly to improve student learning of soils principles and applications. Highlighted are some of activities that have been implemented to increase student learning and teaching effectiveness:

1) Revised content of course annually 2) Organized content into topics and sequence of topics 3) Included more hands-on exercises (e.g., pH and liming activity, field soil sampling, field temperature

measurements; characterizing soil profile in the field) 4) Developed student centered online lessons in erosion and erosion control measures and nitrogen

management with support of seed grant and federal grants. 5) Implemented project based-learning in erosion and erosion management of a site in Lancaster

County 6) Revised the Land Use Planning project. Used my current research data of a watershed in Lancaster

County and used GIS data layers (such as DEM; Erosion Map, Land Use Map etc.) 7) Participated in a yearlong UNL Peer Review of Teaching to improve student learning. 8) Obtained an NSF proof of concept grant to develop application of soil in disciplines such as

agroecosystems, ecology, environmental science, history and geography, forensic science all linked to the same soil principle. This work is multidisciplinary and multi-institutional.

b. Soil Nutrient Relationship AGRO 366 (100% contribution)

5 semesters, 2001 - present, (n=14 – 26) Soil Nutrient Relationships or AGRO/SOIL 366 is designed to help students understand the role of plant nutrients in soil, plant, and environment, and how management practices affect the availability of nutrients and fertilizers to plants, profitability, and the environment. The pre-requisite for this course is Soil Resources 153, which I teach in fall semesters, thus, it is expected that all students in this course would had a basic introduction to soil nutrients without going into deep details. The content of this course also builds on Soil Management or AGRO/SOIL 269 with some overlaps in some areas of the course coverage. The course is a junior level course, however, students enrolled in this course in the past have been from sophomore to senior standing. This course is required for most options (focus) within the Agronomy major and the Soil Science major but a small percent of students from Diversified agriculture, Agricultural business, Animal science majors are also represented. The majority of our students majoring in Agronomy come from farming background and this course fits in the curriculum of students to learn not only the underlying scientific concepts on the behavior and availability of nutrients as environment and management change but practical skills relevant to their current or post-academic profession. One of major ways I have addressed student learning and teaching method for this course is through the year-long participation in the UNL Peer Review of Teaching. Since, this course is pivotal within the broader goals of the Agronomy major curriculum as an applied science, one of my primary goals for participation in the Peer Review process was to improve student learning and skills, specifically finding ways or approaches that will link the principles to the practices. I also have used the student-teacher evaluation and interacted with students to understand the weaknesses of the course. Student-teacher evaluation has consistently rated the course lower than the departmental unit average on general attitude, method, and content. To that end, I have successful answered the following specific questions in this review process:

1) Are the current course goals adequate to the audience of the course? 2) Are the topics or content adequate or more aligned with goals? 3) Are the activities designed to facilitate long-term understanding 4) Are teaching delivery methods/tools/techniques adequate to the audience? 5) What are ways of presenting the materials with the science being less threatening? 6) Are students learning concepts and skills that are enduring?


7

Through this review process, I was able to implement needed changes to effectively improve student learning. For example, a major semester long summative project was implemented in 2005, where students developed a nutrient management plan for selected plants in two agroecological zones and/or two soils of Nebraska by integrating soil fertility concepts and skills they have learned in the course. Another example of change in the course was the adoption of “Nutrient Management of Agronomic Crops in Nebraska” as a primary text resource. This resource is practical and relevant for students to put course content into the context of Nebraska setting. 4..

5. Teaching Impacts Since joining UNL, I have taught 500 students in the two courses. Although grade is not a true indicator of learning, about 50% of the students in both of my courses earn a letter grade of B- or better. During the course review of Soil Resources 153 conducted in 2002-2003, 77% of students who responded agreed that the course was valuable for preparing them for other academic courses and 78 to 64% said that they have applied the knowledge gained in the course often and the course has prepared them for their intended or current profession. Other indirect evidence of impact in Soil Nutrient Relationship include students consulting or discussing with me on soil fertility management issues of their current profession. Often these informal discussion with students who have taken the course in previous semesters involved concepts discussed in the course. Another example of direct impact on student, is expressed in conversation but sometimes in writing.

RESEARCH 1. Overall Research Framework My research has been on soil and water protection and improving soil quality and nutrient management at the state, regional, and international levels. Much of my research is phosphorus related (nutrition, soil fertility, management, environmental protection) that spans from fundamental processes to developing decision support tools. These related research have helped me to leverage funding resources and personnel to support project activities. The key elements of my research program include: 1) Maximizing organic P utilization by plant 2) Understanding basic processes associated with surface and subsurface soil acidification 3) Developing soil acidification management strategies 4) Developing decision tools to reduce sediment and phosphorus losses. 5) Improving no-till systems by increasing soil carbon and improving soil nutrient distribution through

occasional tillage. 6) Improving sorghum yield through improving water conservation, soil conservation, and nutrient

management in semi-arid regions of eastern Africa.

Key elements 1, 2, and 3 are soil and plant nutrition fundamental research focused on understanding processes and factors affecting soil plant-relationships and mycorrhizal relationships. Hypotheses have been tested through experiments conducted under controlled environment. Key element #4 is applied research conducted at the watershed level.

A major goal is to develop decision tools for clientele in selecting BMPs that are economical not only in reducing soil loss but sustaining productivity.

Major efforts include modeling at the watershed level various BMPs and evaluating the economics of each BMP.

Key element #5 addresses carbon sequestration, changes in soil properties, and soil productivity of occasional tillage of no-till. Hypotheses are being answered through field and laboratory research. Key element #6 is an international research focused on water harvesting techniques and nutrient management for resource-poor small-scale farmers.

Hypotheses addressed through research on farmers field throughout semi-arid sorghum regions of Ethiopia, Uganda, and Mozambique.

Major thrusts include economic growth, capacity building through research and leadership trainings of young scientists in host countries and promotion and adoption of technology.

Collaboration in research projects has been very critical to the establishment of my research program, especially in the applied research projects because of my large teaching appointment. A total of six graduate students addressed and/or are addressing many of these research questions.

2. Current Research Activity Understanding processes involved in management induced soil acidity; effects of acidity on soil chemistry, P dynamics and mycorrhizae; liming strategies to eliminate Al and Mn toxicities; phosphorus desorption and adsorption of soil and manure amended soil; soil and water conservation for sorghum production in semi-arid climates of eastern Africa (international agriculture); tillage impact on soil properties; assessing erosion of soil and nutrients at the watershed level. a. Soil Conservation and Water Quality Project: Effects of manure on soil P level and soil P stratification and prediction of soil P dynamics over a range of manure and soil managements using a modeling approach Funding: USGS, Nebraska Research Initiatives Highlights:

Soil Bray–P in 0–5-cm vs. 0–15-cm depth increases P–index risk towards manure application rates.

The P–index provides a snapshot of P loss risk but it does not predict the change in the risk over years of manure application that is exacerbated by P stratification.

Simulation models will enable the P–index to predict changes in P loss risk over time for different management scenarios and climatic regimes.

P–index can be improved as a tool if provisions are made for P stratification in comprehensive nutrient management programs.

Potential Impact/Usefulness/Outcome: Improvement of soil and phosphorus loss risk index. ______________________________________________________________________________ Project: Pollution and economic decision support tool for impaired watershed management plans in eastern Nebraska Funding: USDA-CSREES, Williams Endowment, Nebraska Department of Environmental Quality Highlights:

Sediment, phosphorus, nitrate, and ammonium loading, entering the Wagon Train Lake of the Wagon train watersheds in eastern NE, are being monitored at the both farm and main creek channel levels since 2003. Overland flow is the main carrier of nitrate, bio-available P, and sediment and reveals the interrelationship between rainfall/snowmelt and pollutant loadings under the current watershed settings. With significant BMP implementation in the watershed in past few year, the total suspended

sediment (TSS) load is still 26% higher than 5 Gg yr-1

, the set target goal of TSS load to the Wagon Train LakeStream bank erosion maybe another major contributor of sediment to this watershed and have began evaluating stream bank erosion.

Potential Impact/Usefulness/Outcome: Development of a Pollution Economic Decision Tools (PEDTs) for policy makers and clientele in the watershed to improve water quality of the Wagon Train Lake. Reduction in sediment load to less than 5 Mg yr-1. Reduction in pollutants entering the Gulf of Mexico. ______________________________________________________________________________ Project: Improvement of turbidity measurements for direct estimation of total suspended solids (TSS) in water Funding: USDA-CSREES, ARD equipment funds Highlights:

An improved method was developed to measure TSS using sucrose solution.

Field runoff TSS concentrations were better explained by turbidity measured in sucrose solution than distilled deionized water, especially for runoff samples containing <1 g L-1 TSS.

A sucrose solution of 1.30 kg L-1 is proposed as a better suspending medium for measuring TSS because it de-emphasized the effects of particle size distribution on turbidity and TSS estimation compared to water as a suspending medium for runoff samples in water quality research.

Potential Impact/Usefulness/Outcome: Improved estimation of TSS load into water bodies by commercial laboratory, research laboratory, and research hydrologist. ___________________________________________________________________________ Future research activities

Quantifying streambank erosion rates and its total contribution of sediment to surface water bodies of southeastern Nebraska.

Erosion and sediment contribution of urban lands to water quality

Modeling erosion estimates for different types of urban activities

Developing BMPs and decision tools for erosion control of urban lands in Nebraska. b. Nutrient Management Project: Soil pH stratification and localized liming on sandy soils Funding: Hatch, USAID-INTSORMIL Highlights:

Research in progress with MSc. student due to finish in December 2005.

Above ground sorghum biomass was not affected by acid treatments.

Root proliferation limited with pH lower than 5.0 in the subsurface soil layer.

Soil solution aluminum and manganese levels increased significantly for soil below pH 5.5

Trends in root surface area and soil mycorrhizal are being evaluated Potential Impact/Usefulness/Outcome: Improving effectiveness and economics of liming to alleviate pH stratification on no-till system. ____________________________________________________________________________ Project: Starter fertilizer for no-till sorghum production in Nebraska. Funding: USAID-INTSORMIL Highlights:

Yield response was more frequent in upland environments than in bottomlands

Placement at 5 cm to the side and 5 cm deep and in-furrow placement were generally more effective than over-the-row placement.

Starter fertilizer reduced sorghum grain moisture at harvest in ¼ of the environment tested.

Response of no-till grain sorghum to starter fertilizer application was not economical. Potential Impact/Usefulness/Outcome: Starter fertilizer application on dryland sorghum in eastern Nebraska are not profitable. _____________________________________________________________________________ Project: Occasional tillage to improve the no-till sorghum-soybean rotation. Funding: USAID-INTSORMIL Highlights:

Evaluate effects of four tillage practices, conducted in one year only, relative to continuous no-till.

P uptake and grain yield not affected by the tillage treatments.

One time tillage had little effect on the composition of microbial communities, total microbial biomass, but reduced mycorrhyzal colonization.

Potential Impact/Usefulness/Outcome: Increased production on dryland no-till due to occasional tillage with an average gain worth $16/acre/yr and a total value of $15 M/yr to NE producers. Additional carbon sequestered in the surface 2 inches of soil is


14

350 lbs/acre/yr (assuming soil organic matter in the surface 2 inches will increase by 1% of the soil weight in this layer every 10 years with occasional tillage as compared to continuous no-till), the increase in carbon sequestration is about 150,000 t/yr. __ ____________________________________________________________________________ Future research activities:

Evaluate pH stratification effect on other crops, such as soybean

Fine tune lime recommendation for different crops

Evaluate liming strategies for no-till systems

Long term monitoring of one time tillage effect of no-till on yield and soil organic matter.

Nutrient management and dynamics in aging golf greens

c. International Program Project: Nutrient and water management research in Ethiopia. Funding: USAID-INTSORMIL Highlights:

Evaluating water harvesting and tillage effects in three semi-arid sorghum production locations varying in elevation.

Tillage include: Traditional, e.g. tilled with maresha, broadcast sowing, and shilishalo for weed control; tie ridging using modified maresha (a test implement); conservation tillage or reduced tillage.

Nearly all farmers found tie-ridging to be superior to their typical practice of flat cultivation for reducing runoff and improved crop performance.

Capacity Building:

Supported two MSc students at Alemaya University, Ethiopia, working on water harvesting techniques and soil fertility

Supported training of two Ethiopian scientists to participate in Integrated Soil Fertility Workshop for Sub-saharan Africa hosted by West Africa.

Co-hosted two visiting scientists from Ethiopia at UNL Potential Impact/Usefulness/Outcome: In-situ water harvesting adoption by farmers in the appropriate sorghum regions will increase yield by at least 50% and increase farm income. In capacity building two students have been trained through MSc. degree and are now main research partners. Twenty nine extension staff have been trained to conduct demonstrations and field days in their respective districts to disseminate water conservation and nutrient management techniques. ______________________________________________________________________________ Project: Nutrient and water management research in Uganda Funding: USAID-INTSORMIL Highlights:

Economic and agronomic feasibility of low input practices for soil fertility management in two communities each of eastern Uganda.

Striga and moisture deficit are significant problems in the area.

Significant increase in sorghum grain yield in response to the application of P and N as compared to a mucuna relay and preceding cowpeas,

Demonstrated that P is required in addition to the N supplied by the leguminous cowpeas and mucuna through biological nitrogen fixation.

Capacity Building:

Progressing on development of phosphorus management maps for eastern Africa.

Clay content accounted for 78% of the variation in P sorption over all soil samples.

Clay combined with carbonates accounts for 90% of the variation in P sorption. Potential Impact/Usefulness/Outcome: Development GIS based P management maps for eastern Africa useful for researchers, agricultural research organizations, NGOs, extension, and farmers. ______________________________________________________________________________ Project: Creation of sorghum database and atlas for Eastern and Southern Africa. Funding: USAID-INTSORMIL Highlights:

24 sorghum production areas delineated for Ethiopia, Uganda, Kenya, and Mozambique

Data collection for Tanzania and Eritrea still in progress

Greatest causes of yield loss identified as stalk borer, water deficits, striga, bird damage, N deficiency, weeds, and shoot fly for the sorghum production areas of Ethiopia, Uganda and Kenya, the.

Dominant uses of sorghum in Ethiopia, Uganda and Kenya, are baked foods, injera, cooked foods, fuel, fodder, non-alcoholic beverages, alcoholic beverages, and other uses.

Sole crop production estimated as the main cropping system (84%) with corn and bean as the main associated crops in intercropping.

Potential Impact/Usefulness/Outcome: Development of GIS maps that will be useful for researchers, NGOs, agricultural research organizations, and policy makers. ______________________________________________________________________________ Future international activities:
