10 Questions
Match the following soil nutrients with their primary functions:
Lime = Remove acidity and improve microbial activity Phosphorus (P) = Important in young plant development and cell division Potassium (K) = Improves water uptake and storage of carbohydrates Magnesium (Mg) = Integral component of chlorophyll and important for efficient plant growth
Match the following symptoms with their corresponding nutrient deficiency:
Stunted crop growth and purple color = Phosphorus (P) deficiency Weak plants, leaf scorching, and short plant stature = Potassium (K) deficiency Yellowing between veins of older leaves = Magnesium (Mg) deficiency Bright yellow color on leaves and extremely stunted plant = Sulphur (S) deficiency
Match the following soil amendments with their effects on soil properties:
Soil pH and moisture = Lime makes soils easier to till and improves drainage Organic Matter (FYM, Slurry, Composts) = Improves organic matter breakdown and root development Temperature = Affects microbial activity and earthworm growth Artificial Fertilisers = Provides nutrient supply and improves clover & grass growth
Match the following artificial fertilizer packaging with their respective sizes:
Small bags = 50kg Big bags = 500kg Bulk fertiliser = Varies but typically large quantities for commercial use No matching pair = N/A
Match the following nutrient losses with their corresponding pathways:
Leaching through drainage water = Loss of lime Absorption by crops and livestock = Loss of lime Evaporation from soil = Loss of potassium (K) No matching pair = N/A
Match the type of nitrogen fertilizers with their descriptions:
Ammoniacal Nitrogen = Slower acting than nitrate, not easily leached C.A.N. = 27.5% N- half as nitrate, half as ammonium, suitable for grass esp. spring grazing, suitable for any crop Ureic Nitrogen = Obtained from urea, organic N form, slow acting, availability affected by soil temp and moisture, requires moisture, not suitable for summer applications Nitrate Fertilizers = Readily available, quick acting, applied as top dressing, prone to leaching
Match the organic fertilizers with their types:
Slurry = Liquid organic fertilizer Farmyard Manure = Solid organic fertilizer Sewage Sludge = Organic fertilizer derived from waste Industrial Sludges = Organic fertilizer derived from industrial waste
Match the safety precautions with the corresponding actions for handling slurry:
Bacterial decomposition = Produces gases such as Carbon dioxide, Methane, Ammonia and Hydrogen sulphide Remove all stock from building = When agitating or adding silage effluent to slurry Agitate and spread when air movement possible = Open all ventilation- create draught- gas will linger Have agitate points outdoor and use Breathing apparatus if entering tank = Safety measures for handling slurry
Match the type of livestock with their influence on slurry storage:
Type of livestock = A factor influencing slurry storage Number of livestock = A factor influencing slurry storage Slurry storage = Depends on where you are from Slurry calculation = Formula: Slurry= Number of animals x volume of excreta x weeks storage
Match the timing of manure application with its effect on N availability:
Best timing for manure application = Spread in the spring compared to the summer and autumn (have 70% applied by end of April) Effect on N availability = Maximize slurry fertiliser value and reduce artificial fertiliser application rate Rate of application during Feb/March period = 33,000l/ha Safety measures for manure application = Bacterial decomposition produces gases such as Carbon dioxide, Methane, Ammonia and Hydrogen sulphide
