5 Use the information supplied below to complete the questionnaire. FERTILISATION PROGRAM CITRUS. Orchard: Orchard 10 Size: Cultivar Delta Valencias Trees per ha: 100. /Variety : Fertiliser Quantity Time of Application soil Applications g per tree Limestone Ammonium Nitrate (LAN) 500g July LAN 250g August LAN 100g September Potassium Chloride (KCL) 500g September Potassium Chloride (KCL) 250g October Dolomitic Lime 4000g October Foliar Sprays g per 100l water Low Biuret Urea 1000g July Manganese Sulphate 200g October Zinc Nitrate (5%) 150ml October Solubor 150g October Remarks: 1.

6 Manganese, Zinc nitrate and Solubor are compatible. 2. Spread the lime over the entire area allocated per tree. 3. Apply 10 litres of the spraying solution per tree. Version: 01 Version Date: July 2006. Implement soil fertility and plant nutrition Practices 4. Primary Agriculture NQF Level 4 Unit Standard No: 116311. Develop a soil and foliar application program for orchard 10. Model Answer(s): FERTILISATION PROGRAM FOR soil APPLICATIONS FOR ORCHARD 10. (GRAMS PER TREE). Fertiliser Jul Aug Sep Oct Nov Dec Total LAN 500 250 100. KCl 500 250. Dolomitic 4 000.

7 Lime FERTILISATION PROGRAM FOR FOLIAR SPRAYS FOR ORCHARD 10. (GRAMS OR MILLILITRE PER 100 LITRES WATER). Chemical Jul Aug Sep Oct Nov Dec Total Low Biuret 1 000 g Urea Manganese 200 g Sulphate Zinc Nitrate 150 ml (5%). Solubor 150 g 1. What is the total mass LAN required in July for orchard 10? Model Answer(s): 500 g per tree and there is 100 trees per ha and there is 3 ha = 500 g * 100 * 3. =150 000 g or 150 kg LAN in total 2. What is the total mass of potassium chloride required for the orchard? Model Answer(s): 500 g in September and 250 g in October per tree = 750 g in total per tree.

8 For the 3 ha field with 100 trees per ha = 750 g * 100 * 3. =225 000 g or 225 kg KCl in total Version: 01 Version Date: July 2006. Implement soil fertility and plant nutrition Practices 5. Primary Agriculture NQF Level 4 Unit Standard No: 116311. 3. How many litres of zinc nitrate must be ordered for orchard 10? Model Answer(s): 2 500 l are necessary per ha and you mix 150 ml per 100 l water. 2 500 l / 100 l = 25 times * 150 ml per 100 l = 3 750 ml per ha and there is 3 ha 3 ha* 3 750 ml per ha = 11 250 ml or l of Zinc nitrate (5%) in total. 4. If the only zinc nitrate available contains 10% Zn, what will the application rate be?

9 Model Answer(s): The zinc nitrate used for previous question contained 5% Zn, while the zinc nitrate available contains 10% Zn, therefore you would half the amount of zinc nitrate necessary. 150 ml / 2 = 75 ml Zinc nitrate (10%) per 100 l water. My Notes .. Version: 01 Version Date: July 2006. Implement soil fertility and plant nutrition Practices 6. Primary Agriculture NQF Level 4 Unit Standard No: 116311. Instructions to learner: Questionnaire. SO 1. Learner Guide: Page 24 Facilitator Guide: Page 12. In the fertilizer example for sunflower, it was indicated that you would need 22 kg N, 11 kg P and 10 kg K per ha and that translated in buying 117 kg 2:3:2 (22%), 14 kg 1:0:1 (36%) and 43 kg LAN per ha.

10 Redo the problem and see if you get to the same answers. The fertilizer requirements are for one ha, how much of each fertilizer type would you have to buy for 100 ha? Clearly show all calculations. Model Answer(s): The learner should get to the same answer of 22 kg N, 11 kg P and 10 kg K per ha. P has to be applied before or with plant , therefore one first have to calculate how much of the P containing fertilizer to apply. N and K containing fertilizers can be top dressed later and we do not worry about it just yet. How much 232 (22%)? In 232, there is 7 parts of N, P and K or in other words there is 22 kg NPK in a 100 kg 232.
