Question 3 of 11intermediate🔍 AnalyzeShort Answer3 marks

Snehal dug two pits, A and B, in her garden. In pit A, she put fruit and vegetable peels and mixed it with dried leaves. In pit B, she dumped the same kind of waste without mixing it with dried leaves. She covered both the pits with soil and observed after 3 weeks. What is she trying to test?

Correct Answer

Snehal is testing whether mixing dried leaves with fruit and vegetable peels affects the rate of decomposition and manure formation.

Dried leaves provide better aeration in the compost pit, allowing microorganisms like bacteria and fungi to function more efficiently.

The dried leaves also help maintain optimal moisture levels and create air spaces that microorganisms need for aerobic decomposition.

Pit A with mixed dried leaves is expected to decompose faster and produce better quality manure compared to Pit B.

Explanation

Activity 2.7 in the chapter demonstrates that microorganisms like fungi and bacteria break down plant waste into nutrient-rich manure. The chapter also mentions that manure formation occurs at optimal temperature and appropriate moisture level. Dried leaves help create air spaces for aerobic bacteria to function properly. Gardeners collect dry leaves and plant waste together in pits to make natural manure, as described in Section 2.4.1.

Solution Steps

  1. Snehal is testing whether mixing dried leaves with fruit and vegetable peels affects decomposition rate and manure formation
