Soil enrichment of dissolved ions and inorganic salts occurs due to
1 Weathering
2 Pedogenesis
3 Humification
4 All the above
Explanation:
Majority of the nutrients that are essential for the growth and development of plants become available to the roots due to weathering and breakdown of rocks. These processes enrich the soil with dissolved ions and inorganic salts. Pedogenesis and Humification both enriches soil with dissolved ions and inorganic salts.

Fertilizer contains
1 Micronutrient
2 Macronutrient
3 1 and 2
4 None of them
Explanation:
Both macro-nutrients ( \(N, P, K, S\), etc.) and micro-nutrients \((\mathrm{Cu}, \mathrm{Zn}, \mathrm{Fe}, \mathrm{Mn}\), etc.) form components of fertilisers and are applied as per need.
