9 Questions
Match the nitrogen fertilisers with their characteristics:
Nitrogen Fertilisers = Readily available, quick acting, prone to leaching Ammoniacal Nitrogen = Slower acting than nitrate, not easily leached, 3-5 weeks conversion C.A.N. = Half as nitrate, half as ammonium, suitable for grass esp. spring grazing Ureic Nitrogen = Slow acting, availability affected by soil temp and moisture
Match the types of organic fertilisers with their examples:
Slurry = Animal excreta Farmyard Manure = Organic matter from farms Sewage Sludge = Waste material from sewage treatment plants Industrial Sludges = Waste material from industries
Match the gases produced during bacterial decomposition with their names:
Carbon dioxide = Product of bacterial decomposition Methane = Gas produced during decomposition Ammonia = Gas released during decomposition process Hydrogen sulphide = Result of bacterial breakdown
Match the safety precautions with their purpose:
Timing of Manure Application in Spring = Maximizing slurry fertiliser value and reducing artificial fertiliser application rate Rate of Application - 33,000l/ha during Feb/March period = Ensuring proper distribution of nutrients on the field Calculating Slurry Storage - Slurry = Number of animals x volume of excreta x weeks storage = Determining the required storage capacity for animal waste Effects of Manure Application in Summer and Autumn = Best time for spreading manure to achieve optimal nitrogen availability
Match the nutrient with its importance in plant development:
Phosphorus (P) = Important in young plant development, cell division, root development Potassium (K) = Improves water uptake, storage of carbohydrates, strengthens cereal straw Magnesium (Mg) = Integral component of chlorophyll, deficiency leads to yellowing of leaves Sulphur (S) = Important in protein production, deficiency causes bright yellow color on leaves
Match the nutrient with its deficiency symptoms:
Phosphorus (P) = Stunted crop growth, purple color, poor milk yields Potassium (K) = Weak plants, short plant stature, scorched leaf edges Magnesium (Mg) = Yellowing between veins of older leaves, grass low in Mg causes Hypomagnesia Sulphur (S) = Bright yellow color on leaves, extremely stunted plant
Match the soil condition with its impact on crop yields:
Soils low in lime = Poor crop yields, poor nutrient availability Soils high in acidity = Low productivity, measured on pH scale Ideal soil pH 6.5 = Optimal conditions for plant growth and nutrient availability Lime lost through leaching = Drainage water, crops & livestock affecting soil fertility
Match the function of Lime with its effects on soil improvement:
Remove acidity = Improves organic matter breakdown, microbial activity/root development Improve drainage = Makes soils easier to till, increases earthworm activity Improve clover & grass growth = Enhances soil fertility and crop productivity Increase earthworm activity = Improves soil aeration and nutrient circulation
Match the artificial fertilizer packaging with the corresponding weight range:
Small bags - 50kg = Suitable for home gardeners or small-scale farmers Big bags - 500kg = Commonly used by medium to large-scale farmers Bulk fertiliser = Large quantities suitable for commercial agricultural operations Artificial Fertilizers = Available in various packaging options to suit different needs
Learn about the significance of using lime in soil management. Discover why lime is essential for acidic soils to improve nutrient availability and crop yields. Explore how lime is lost through leaching and its role in balancing soil pH levels.
