Describe soil fertility Which 2 soil constituents have the same percentage Give one advantage and disadvantage of organic manure Describe the process of rock weathering

Here are the answers to your questions:

• Describe soil fertility Soil fertility is the ability of soil to sustain plant growth by providing essential plant nutrients and favorable soil physical, chemical, and biological characteristics as a habitat for plant growth.

• Which 2 soil constituents have the same percentage Based on the ideal soil composition chart, Water and Air both have 25%.

• Give one advantage and disadvantage of organic manure

  • Advantage: Organic manure improves soil structure, water retention, and aeration, leading to healthier soil over time.
  • Disadvantage: It can be bulky and difficult to transport and apply in large quantities, and nutrient release can be slower and less predictable than synthetic fertilizers.

• Describe the process of rock weathering Rock weathering is the process by which rocks and minerals are broken down into smaller pieces or altered chemically at or near the Earth's surface. It can be physical (mechanical breakdown without chemical change) or chemical (decomposition through chemical reactions).
