Plant & Soil Science Courses
PLS 500 - Soil Fertility
Soil Fertility. Three semester hours. The essential elements in the soil will be discussed, and soil samples will be analyzed to determine the level of elements that are contained. Prerequisites: PLS 309, 320 and CHEM 111, 112, 211.
PLS 501 - Ag & Bio & Instrumentation
Principles, equipment, and techniques for measuring variables in plant, soil, and environmental sciences. Spectrophotometry, chromatography, atomic absorption, weather sensors and data loggers, and tissue culture are covered.
PLS 502 - Advanced Crop Physiology
The undergraduate class PLS 381 (a prelude to this proposed class) covers physiological processes underlying crop growth and development and the effect of crop management practices on physiology. This PLS 502 Advanced Crop Physiol class will briefly cover those principles in PLS 381 but will also cover the following: crop physiological responses to water (and other abiotic) stresses, the details of yield components and how they compensate for each other, nitrogen metabolism as it relates to grain growth and quality, fertility effects on forage yield and quality. Laboratory exercises will be designed to elucidate these principles. Prerequisites: PLS 115 or PLS 120, PLS 381 or PLS 326 or PLS 455 or PLS 460.
PLS 515 - Pasture Management
Pasture Management. Four semester hours. A careful study of the literature concerning the soil and vegetative problems in regard to establishing, restoring, and maintaining pastures. Consideration will be given to pasture plans for this section of Texas, fertilizers to use, and good pasture practices to be observed. Prerequisite: PLS 326.
PLS 589 - Independent Study
Individualized instruction/research at an advanced level in a specialized content area under the direction of a faculty member. Prerequisites Consent of department head. Note May be repeated when the topic varies.
PLS 597 - Special Topics
Special Topics. One to four semester hours. Organized class. May be repeated when topics vary.
