Step 1: Give THREE reasons in favour of use of organic fertiliser in your school garden (1.1.1). • Organic fertilisers improve soil structure, increasing its water-holding capacity and aeration. • They release nutrients slowly over time, providing a steady supply for plants and reducing the risk of nutrient leaching. • Organic fertilisers enhance beneficial microbial activity in the soil, which helps in nutrient cycling and disease suppression. Step 2: Suggest THREE characteristics of crops that could be used for green manure (1.1.2). • Fast-growing: They should establish quickly to cover the soil and produce biomass efficiently. • High biomass production: They need to produce a significant amount of plant material to be incorporated into the soil. • Nitrogen-fixing ability: Many green manure crops, especially legumes, can fix atmospheric nitrogen, enriching the soil with this essential nutrient.
