| Kursets målsætning |
The aim of the course is to convey to the students substantial knowledge of sustainable soil fertility management and improvement by cropping system, fertilization and the use of integrated plant nutrient systems.
On successful completion of the course, students have a scientific basis for management and improvement of soil fertility including the use of organic and inorganic fertilizers, and Integrated Plant Nutrient Systems to obtain yield increases and sustainability of the agro-ecosystem. |

| Kursusindhold |
Soil fertility refers to the inherent ability of a soil to act as growth medium for plants, including the capacity of the soil to supply nutrients and water to plants in adequate amounts and suitable proportions. Hence the course has the following main elements:
1. Fertility of soils in the tropics, actual and potential crop production
2. Nutrient cycling in the tropical and subtropical agro-ecosystems
3. The role of management of availability and bioavailability of plant nutrients for plant growth and crop production and for the losses of nutrients from agro-ecosystems
4. Soil fertility management
5. The role of tilth and tillage for availability and bioavailability of plant nutrients
6. Soil organic matter turnover in tropical soils
7. The role of optimised management of soil organic matter and soil fauna
8. The role of improved circulation and recirculation of nutrients from renewable natural resources including manure and the added value offered by leguminous plants, perennial grasses and agro-forestry
9. Natural sources of plant nutrients, fertilisers and fertilisation
10. Nutrition of important tropical and subtropical crop plants and crop yield and quality
11. Fertility and fertilisation of paddy soils and crop yield and quality
12. Interactions between soil fertility, plant nutrition and pests
13. Place and role of local and external sources of plant nutrients in cropping systems and their evaluation
14. Plant nutrient management in farming systems, using Integrated Plant Nutrient Systems Rationale
It is probably true that after the human population issue there is no more important problem facing the world than the improvement of planning and management of natural resources including soil, plant nutrient and water resources towards a higher degree of sustainability. However the total available land is limited and finite.
Due to increasing demographic pressure and needs for food the resulting exhaustive exploitation of soil by agriculture and animal husbandry imply severe environmental degeneration, which in turn generates a degradation of natural resources including the soil fertility in many areas of the world. Under these circumstances the deficiency of plant nutrients in the soil represents the most limiting factor to plant production. For that reason, improvement of nutrient circulation/recirculation within the system, improvement of availability and bioavailability of nutrients in the soil, and reduction of nutrient losses by leaching and soil erosion are key elements in the sustainability of agro-ecosystems. However, due to increasing population it is not enough to optimise the utilisation of natural nutrient resources. It is also necessary to use external sources e.g. of phosphorus and nitrogen fertilisers. In this connection the added value offered by leguminous plants, perennial grasses and agroforestry must not be overlooked.
Sustainability of the soil fertility and its management in the tropics are thus an issue of major, and the major themes for the present course: Integrated Plant Nutrient Systems and Soil Fertility Management in the tropics. |

| Undervisningsform |
| The course consists of lectures, exercises and project work in groups.The students work in project groups according to their main interests. Each group carries out case studies of farming systems with a given combination of climate and soils. The project work includes an oral presentation of the case study results (description, analysis and diagnosis) and the development of appropriate strategies and plans of integrated plant nutrition and soil fertility management at a course seminar. Finally a written report is submitted as part of the assessment. |
