1. Soil Conservation And Its Importance For Agriculture And Economy On Slopes. Julio Alvarado. Rafael Pimentel. Sergio Garvisu.

2. Soil is the most important resource in agriculture. It provides to the plants everything they need.

3. It is estimated that every year almost 4 tons of soil are lost

4. Soil takes one hundred years to form one centimeter.

5. Most of the agriculture in Nicaragua, El Salvador and Honduras is developed on slopes.

6. And most of the poor people lives on slopes.

7. The practice of agriculture on slopes causes the lost of until 16 tons of soil

8. All that soil goes to the rivers and then to the ocean.

9. So that soil cant be recovered.

10. And the soil on slopes is each year less.

11. So if the soil is less, there is less fertility in the soil to grow crops.

12. And the quality of our food is lower than what it was years ago

13. The two main causes of the soil lost, better called erosion.

14. Hydric erosion.

15. Eolic erosion.

16. The question is. Which could be the solution to avoid and control this big problem? The answer: Soil conservation measures on slopes.

17. There are many things we can do to conserve the soil and its fertility by practicing a well done agriculture.

18. Creating hedgerows on slopes.

19. By creating dead barriers with rocks.

20. By implementing leveled curves.

21. By making drains.

22. So that way, we can conserve the soil and its fertility.

23. And the people who lives on slopes will produce better crops with better qualities and will earn more money

24. Leave this planet in better conditions than you found it Baden Powell

25. Thanks for your attention :D have a nice day
