Lakhmir Singh Science Class 8 Solutions for Chapter 1 FAQs

What is ploughing?

Ploughing is the process of turning and loosening the soil before sowing seeds. It helps to aerate the soil, uproot weeds, and mix nutrients evenly, making the land fertile and ready for cultivation.

What is the use of a cultivator?

A cultivator is a farming tool attached to a tractor that helps in loosening the soil quickly and efficiently. It saves time and labor compared to traditional ploughing methods and prepares the field for sowing.

What are any four differences between manures and fertilisers?

Here are four key differences between manures and fertilisers:

Source:

  • Manures are natural substances made from decomposed plant and animal waste.
  • Fertilisers are man-made chemical substances.

Nutrient Content:

  • Manures have low and variable nutrient content.
  • Fertilisers are rich in specific nutrients like nitrogen, phosphorus, or potassium.

Effect on Soil:

  • Manures improve soil structure and increase organic matter.
  • Fertilisers do not improve soil texture and may harm soil health if overused.

Cost and Usage:

  • Manures are cheaper and eco-friendly but work slowly.
  • Fertilisers act quickly and are more expensive.
