15. Let’s practice step by step…

16. progress order step by step…

17. 1.Select crop-group & crop - pepper 2.Select growth method: greenhouse 3.Fill in expected yield: 70 ton / ha 4.Hit: Enter Haifa Nutri-Net: step 1

18. 1.Nutrition data are filled automatically 2.Units can be selected 3.Save data Haifa Nutri-Net: step 1

19. Haifa Nutri-Net: step 2 – Input of soil data INPUT 1. Select by soil data availability 2. Fill in soil data 3. Enter

20. default updated step 2 – consequent updated recommendations OUTPUT 1.Assessment of soil fertility 2. updated recommendations

21. 2.Select fertilization method during growing season Haifa - Nutri-Net : step 3- fertilization 1.Select irrigation method Either or

22. Haifa - Nutri-Net : step 3 1.Dripping was selected 2.Nutrigation was selected

23. Haifa - Nutri-Net : step 3- fertilization It’s now the time to produce the Base – Dressing scheme

24. A Base dressing scheme is built by : 1.A best fit formula, based on common fertilizers or by ……… 2.Free choice between many raw materials

25. Step 4- producing a Nutrigation program: I Defining crop growth stages Ia Finding similar growth conditions in a database Major Growth phases

26. Step 4- producing a Nutrigation program: II Crop- & field- specific data are introduced by growth stages Root system profile Growth phases & irrigation parameters

27. Field- specific irrigation parameters Step 4- producing a Nutrigation program: II Crop- & field- specific data are introduced by growth stages

28. Step 5- producing an irrigation program: locating similar agro-meteorological conditions in database Regions Continents

29. Step 5- producing an irrigation program: Full agro-meteorological details of the location selected in the database

30. Step 5- producing an irrigation program: The agro-meteorological conditions are inserted in the crop water- requirement table

31. Step 5- producing an irrigation program: A detailed irrigation table is proposed

32. Step 6- producing a nutrigation program: Previously agreed- upon nutrients are recalled and expressed as fully soluble products

33. Step 6- producing a nutrigation program: The nutrients are allocated by growth stages

34. Step 6- producing a nutrigation program: The products are allocated by growth stages

35. Step 6- producing a nutrigation program: Total Fertilizers concentrations in the irrigation water is worked out by growth stages
