Soil erosion

Cards (63)

  • Soil erosion is the process by which soil particles are removed from one location and transported to another.
  • Fertilizers are natural and artificial substances containing chemical elements that improve the growth and development of plants.
  • Incomplete fertilizer contains two fertilizer elements.
  • Fertilizer is a natural and artificial substance containing chemical elements that improve the growth and development of plants.
  • Single/Straight/Simple Element Fertilizer contains only one primary fertilizer element.
  • Compound Fertilizer containing three elements are designated as complete fertilizer.
  • Fertilizer Elements are those nutrient elements the demand for which is particularly critical for plant nutrition.
  • Active Ingredients refer to the primary nutrient nitrogen (N) and oxidized forms of phosphorus (Phosphorus pentoxide P2O5) and potassium (Potassium oxide, K2O) in a single carrier or mixture supply them.
  • Carrier is any material that contains (carries) one or more of the fertilizer elements.
  • Fillers are materials, which may or may not possess manorial value, added to compound fertilizers to make up the weight to get them conformed to a predetermined specification in terms of percentages of the active ingredients.
  • The amount of Muriate of Potash (kg) needed to meet the recommended rate of K2O is 0-0-60 kg NPK/ha.
  • The amount of Urea (kg) needed to meet the remaining recommended rate of P2O5 is 0-0-30 kg NPK/ha.
  • The amount of Urea (kg) needed to meet the remaining recommended rate of N is 0-0-60 kg NPK/ha.
  • The amount of Complete (kg) needed to meet the recommended rate of P2O5 is 30 kg P2O5/ha = 214.3 kgs T14.
  • The amount of Urea (kg) needed to meet the recommended rate of N is 66 kg N/ha = 143.48 kgs Urea.
  • The recommended rate of NPK fertilizer is 90-30-60 kg NPK/ha.
  • The amount of pure N in AP is 150.0 kgs x 0.16 = 24.0 kgs N.
  • Fertilizer Computation involves the process of determining the amount of pure N contained in the amount of AP that will be applied, and then computing for the recommended N, P, K, and other nutrients.
  • Fertilizer Ratio is a term which shows the percentage of active ingredients N, P2O5, K2O, in this order in a compound fertilizer.
  • Fertilizer Analysis (or Fertilizer Guarantee) is a statement of the proportion of plant food a fertilizer contains.
  • Fertilizer Analysis is graded.
  • Fertilizers guarantee to supply 15% total active ingredients are described as low in analysis.
  • 15% - 25% are medium in analysis.
  • 25% - 30% are high analysis.
  • The recommended rate of Ammonium Sulphate (21-0-0) is 90 kg N/ha, which is equivalent to 428.6 kgs.
  • 0-30-60 kg NPK/ha
  • 30% above is concentrated.
  • Mang Merlito needs the following fertilizers in a hectare: 428.6 kgs of 21-0-0, 166.7 kgs of 0-18-0, and 100.0 kgs of 0-0-60.
  • The available fertilizers are Urea (46-0-0), Ammonium Phosphate (16-20-0), and Muriate of Potash (0-0-60).
  • The recommended rate of NPK fertilizers is 90-30-60 kg NPK/ha.
  • Step 1: Start the calculation with the use of Ammonium Phosphate (Ammonium Phosphate).
  • Then compute first the recommended P2O5.
  • The recommended rate of Muriate of Potash (0-0-60) is 60 kg K2O/ha, which is equivalent to 100.0 kgs.
  • GIVEN: Recommended Rate: 90-30-60 kg NPK/ha
  • 0-0-0 kg NPK/ha
  • Fertilizers: Urea (46-0-0), Ammonium Phosphate (16-20-0), and Muriate of Potash (0-0-60).
  • The formula for computing the amount of fertilizers to be applied is:
  • The recommended rate of Solophos (0-18-0) is 30 kg P2O5/ha, which is equivalent to 166.7 kgs.
  • Amount of Ammonium Phosphate (kg) = 30 kg P2O5/ha, which is equivalent to 150.0 kgs.
  • Mang Merlito needs to apply fertilizers in an area calling for a recommendation rates of 90-30-60 kg NPK/ha.
