Retrospective Theses and Dissertations

Biotechnology by-products and animal manures have received considerable attention in recent years because of the problems associated with their disposal and because of their potential use as soil amendments and as sources of nutrients for crops. A laboratory experiment was conducted to assess the potential N mineralization in five biotechnology by-products and three animal manures added to an agricultural soil with pH values of 5, 6, and 7 and incubated at 20°C or 30°C. Two greenhouse experiments were conducted by using the same soils to evaluate those materials as sources of N for plants; corn (Zea mays L ...
