Evaluation Of Corn Agronomic Management Practices Following A Rye Cover Crop, Daniel John Quinn
Evaluation Of Corn Agronomic Management Practices Following A Rye Cover Crop, Daniel John Quinn
Theses and Dissertations--Plant and Soil Sciences
Fall implementation of a rye (Secale cereale L.) cover crop (RCC) prior to spring corn (Zea mays L.) planting is a management practice used to improve soil conservation, water quality, and limit herbicide dependence. However, corn growth and yield following a RCC is often reduced due to early-season nitrogen (N) stress and decreased plant emergence, which can limit RCC adoption. The objective(s) of this research were to evaluate corn agronomic management practices (e.g., N and seeding rate management, in-furrow (IF) starter use) following a RCC and determine which management practices can be used to limit corn stress following …
Effect Of Bedding Type And Soil Incorporation On Nitrogen Mineralization Rate Of Broiler Litter Amended Soils, Lydia A. Fitzgerald
Effect Of Bedding Type And Soil Incorporation On Nitrogen Mineralization Rate Of Broiler Litter Amended Soils, Lydia A. Fitzgerald
Theses and Dissertations--Plant and Soil Sciences
Broiler litter (BL) is a high value manure available to Kentucky crop producers to utilize as a fertilizer. The rate of BL application, timing of application, and method of application are all important factors to take into account when utilizing BL. A laboratory incubation was conducted to observe nitrogen (N) mineralization rates of BL amended soils over time under different conditions. Different application methods, application rates, watering frequencies, and bedding materials were used to determine their influence on N mineralization. Broiler litter applied on the soil surface, at lower rates, at lower watering frequency resulted in lower mineralization rates than …
