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. </p><p>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. How much is then N or P or K? 2 of the 7 parts are N, thus 2/7 * 22 kg = 6.3 kg N and the same amount of K. 3 of the 7 parts are P, thus 3/7 * 22 kg = 9.4 kg P In summary then in 100 kg 232 (22%) there is 6.3 kg N, 9.4 kg P and 6.3 kg K. The sum of these three elements gets you back to 22. This is a check to make sure you have calculated the amount of N, P and K correctly. If you can get 9.4 kg P when buying 100 kg 232, how many kg 232 do you have to buy to get 11 kg P per ha? (100 kg 232 / 9.4 kg P) * 11 kg P ha-1 = 117 kg 232 needed per ha. But remember there are also some N and K in the 117 kg 232, but how much? If there is 6.3 kg N in 100 kg 232, how many kg is in 117 kg 232? (6.3 kg N / 100 kg 232) * 117 kg 232 = 7.4 kg N and also 7.4 kg of K. In summary then If you buy 117 kg 232 (22%) you get 11 kg of P, 7.4 kg of N and 7.4 kg of K. Which fertilizer should be calculated next? There is only one fertilizer left which can supply K and two which can supply N, therefore one will go for the fertilizer containing the K, as any additional N needed can be made up with the fertilizer only containing N. Therefore we calculate the amount of 101 (36%) required. How much 101 (36%)? In a 100 kg there is 2 parts N and K and no P. There is thus 18 kg N and 18 kg K in a 100 kg of 101 (36%). As explained there is no other K source, so the amount of 101 have to fulfil in the K requirement for the crop field. We determined that we would need 10 kg K per ha for the field. We already have 7.4 kg K when buying 117 kg 232, so we need 10 kg K 7.4 kg K = 2.6 kg K. We can get 18 kg K when buying a 100 kg 101, so how many kg of 101 do we have to buy when we need only 2.6 kg K? (100 kg 101 / 18 kg K) * 2.6 kg K = 14 kg 101 needed per ha When buying 14 kg of 101, we get 2.6 kg of K but also 2.6 kg of N </p><p>Instructions to learner: </p><p>Questionnaire. 11..22 SSOO 11 </p><p>Learner Guide: Page 24 Facilitator Guide: Page 12</p></li><li><p>Implement Soil Fertility and Plant Nutrition Practices </p><p>Primary Agriculture NQF Level 4 Unit Standard No: 116311 77 </p><p>Version: 01 Version Date: July 2006 </p><p>Now we have to make up the required amount of N by using LAN (28%). How much LAN (28%)? This is a straight fertilizer and not a mixture, thus there is 28 kg N in every 100 kg LAN we buy. How much N do we still need? From the tables we determined we needed 22 kg N. We go 7.4 kg N from 117 kg 232 and 2.6 kg N from 14 kg 101. Thus: 22 kg N 7.4 kg N 2.6 kg N = 12 kg N still needed. (100 kg LAN / 28 kg N) * 12 kg N = 43 kg LAN needed per ha How much 232, 101 and LAN needed for 100 ha? 117 kg 232 per ha * 100 ha = 11 700 kg or 11.7 t 232 for 100 ha 14 kg 101 per ha * 100 ha = 1 400 kg or 1.4 t 101 for 100 ha 43 kg LAN per ha * 100 ha = 4 300 kg or 4.3 t LAN for 100 ha </p><p>1. If the sunflowers were planted on field two, instead of field one, how would it affect the P and K requirement? Why would it affect the requirements? </p><p>Model Answer(s): </p><p>The soil in field two contains more P and K than the soil in field one. Therefore one would need less P and K containing fertilizers. </p><p>2. If the sunflowers were cultivated with irrigation, how would it affect the N, P and K requirements for field number one? Why would it affect the requirements? </p><p>Model Answer(s): With irrigation the yield potential would be higher and also the number of plants per ha. Therefore more N, P and K would be required. </p><p>3. If you did not check the fertilizer stock levels and or did not place an order on time and the only fertilizers available from the supplier is: 1:0:1 (40%), ammonium sulphate (21% N), potassium nitrate (13% N and 38%K) and super phosphate (10.5% P). </p><p>How much of these fertilizers would you buy to fulfil in the fertilizer program set out for field one? Now compile a fertilizer programme for field one, using these new fertilizers. </p><p>Model Answer(s): We start with Super phosphate (10.5%) because it is the only fertilizer containing P. We would need (100 kg SuperP / 10.5 kg P) * 11 kg P = 105 kg Super P per ha Potassium nitrate is the only K containing fertilizer We would need (100 kg KNO3 / 38 kg K) * 10 kg K = 26 kg KNO3 per ha In 26 kg NO3 there is (13 kg N / 100 kg NO3) * 26 kg NO3 = 3.4 kg N Now we need to determine the amount of NH4SO4 which contains only N We still need 22 kg N 3.4 kg N = 18.6 kg N </p><p>We would need (100 kg NH4SO4 / 21 kg N) * 18.6 kg N = 89 kg NH4SO4 per ha </p></li><li><p>Implement Soil Fertility and Plant Nutrition Practices </p><p>Primary Agriculture NQF Level 4 Unit Standard No: 116311 88 </p><p>Version: 01 Version Date: July 2006 </p><p>1. Name four soil properties that will determine the suitability of a soil for a specific crop, cultivated in your area. Note the reasons why these properties are important in a table similar to the one shown below. Also discuss the term stratification as used in describing the soil profile. </p><p>Model Answer(s): Make sure the crop is relevant in the area. The properties can be any of the following with an applicable reason as why the </p><p>learner thinks it is important for that specific crop. Soil depth, drainage, infiltration rate, pH, water holding capacity, soil aeration, </p><p>erosion risk, clay content, structure and compaction, slope, stratification, salt content, nutrient content and nutrient deficiencies or toxicities. </p><p>2. Discuss the term stratification as used in describing the soil profile. </p><p>Model Answer(s): Soil is stratified when layers of vastly different textures are deposited on top of </p><p>each other.
