This book, built from 20 management cases, most of which were selected from La France agricole, offers a comprehensive overview of the most common and emblematic situations on a farm. These situations are illustrated in a way that makes the problem and solutions immediately understandable. The book is organized into ten chapters: 1. Legal forms 2. Cost calculation approaches - conventional methods 3. Complementary cost methods for decision-making 4. How to define your selling price 5. Financing 6. Key financial analysis ratios 7. Dashboard of your farm 8. Cash flow of the agricultural business 9. Investment profitability 10. Evaluation of the agricultural business. Each chapter first reviews the financial concepts and mechanisms related to the topic studied (e.g., investment), before addressing the specificities of the agricultural world. Two practical sheets per chapter detail the calculations and illustrate the decisions to be made. This allows readers to practice before verifying their approach with the suggested answers. The authors have aimed to give the rules mentioned a timeless character, independent of specific elements such as those related to the Finance law. Therefore, they do not delve into agricultural tax optimization in these applications, ensuring that finance does not influence economic reasoning.
