  • Nitrogen mineralization from organic amendments during the second year following application

    Creator:
    Kusonwiriyawong, Charirat
    Abstract:
    Estimates of nitrogen (N) available from long-term application of organic amendments are required to balance N inputs with crop N requirements. Two studies were conducted to (1) determine N mineralized from organic amendments (manures and composts) during year 2 after application, and (2) compare plant-available N (PAN) determined via in...

    Abstract:
    Scientific inquiry in K-12 classrooms tends to be procedural, lacking opportunities for students to gain understanding of how scientific knowledge is constructed through reflection, debate, and argument. Limited opportunity to develop scientific argumentation skills prevents students from practicing the scientific thinking needed to understand the nature of scientific knowledge and...
