An introduction to the looming world food crisis and the scientific basis governing our ability to sustainably meet it. The course explores the biological and environmental constraints on food production, the ways that agricultural science has dealt with these in the past and possible ways for the future, as well as societal and cultural issues, such as population growth, human health, education, and food definitions, that also impact food security. Intended for any student interested in these topics. Students may not receive credit for both this course and PLS 103.

The students in this class will be introduced to design theory and basic techniques of floral design. The basic mechanics necessary to follow the principles of floral design will be stressed. Students will also be exposed to the business basics that are necessary to execute a floral design, as well as the global nature of the floral design industry.

Study of the physical, chemical and biological properties of soils and how these properties relate to plant nutrient availability and plant growth, land- use planning and management issues, and soil and water quality issues. Lecture, three hours; laboratory, three hours.

Directed independent research under the supervision of a faculty member on a selected topic in plant and soil sciences or agricultural ecosystem sciences. May be repeated to a maximum of 9 credits.

A learning experience in plant and soil science or agricultural ecosystem sciences under the direction of a faculty member with supervision from an internship advisor and with clear relevance to a student's program of study. A minimum of 48 working hours will constitute one semester credit hour. May be repeated for a maximum of nine (9) credits.

A study of weed management concepts based on the integration of weed biology and ecology data with cultural, biological, and herbicidal control. Lecture, three hours; laboratory, two hours per week.

A more advanced treatment of soil site evaluations under diverse climatic and physiographic environments. Students will obtain expertise in assessing properties of contrasting soil types and rating them for soil use and management suitability. The course is also used for preparing the UK soil judging team for national college competition. May be repeated to a maximum of four credit hours.

Soil reaction/cycling of elements essential to plant growth; rates, timing and placement of nutrient sources in modern crop/soil management systems; plant and soil sampling and analysis to diagnose plant nutrition stress.

This course will enable students to critically assess, analyze and evaluate forage production and utilization practices on livestock-forage operations in Kentucky and the mid-south region. The course will emphasize the integration of forage science and practice.

Biology, management, and production of major grains and oilseeds in Kentucky and around the world.
