Question of The Day18-05-2025

Which part of the soil contains humus? मिट्टी के किस भाग में ह्यूमस होता है? [SSC MTS 06 October 2021, Shift 2]

Answer

Correct Answer : a ) A-horizon / ए-क्षितिज

Explanation :

The part of the soil that contains the most humus is called the topsoil, also known as the A-horizon.

Humus is a dark, organic material formed by the decay of dead plants and animals.

The A-horizon is the top layer of soil and contains a high amount of both minerals and organic matter.

The presence of humus in the topsoil makes it fertile and suitable for plant growth.

Hence, (a) is the correct answer.

मिट्टी का वह भाग जिसमें सबसे अधिक ह्यूमस होता है उसे ऊपरी मिट्टी कहा जाता है, जिसे ए-क्षितिज भी कहा जाता है।

ह्यूमस एक गहरा, कार्बनिक पदार्थ है जो मृत पौधों और जानवरों के सड़ने से बनता है।

ए-क्षितिज मिट्टी की सबसे ऊपरी परत है और इसमें खनिज और कार्बनिक पदार्थ दोनों की उच्च मात्रा होती है।

ऊपरी मिट्टी में ह्यूमस की उपस्थिति इसे उपजाऊ और पौधों की वृद्धि के लिए उपयुक्त बनाती है।

इसलिए, (a) सही उत्तर है।
