The National Agricultural Institute's (NAI) focus is to create low-cost, textbooks for agriculture, food and natural resources (AFNR) courses. Our textbook series are called, "Just the Facts" and are available in hard copy (at Lulu.com) and electronic format (www.national-ag-institute.org). "Just the Facts" textbooks present the essential subject knowledge in in an open and easy-to-read format. This essential knowledge is supported by a main concept, learning objectives, and key terms at the beginning of each section. Content is further enhanced for student learning by connecting with complementary PowerPoint presentations and websites through QR codes (scanned by smart-phones or tablets) or URLs. Our motto: Agriculture is life. Mission: Supporting and enhancing education in agriculture, food and natural resources. Rick Parker, PhD President
