सार

मिट्टियाँ और जलवायु भारत के फ़सल-प्रारूप को आकार देती हैं; प्रमुख मिट्टी प्रकार विशिष्ट फ़सलों के लिए उपयुक्त होते हैं।

मुख्य बिंदु

  • जलोढ़ मिट्टी सबसे व्यापक है (उत्तरी मैदान, डेल्टा)।
  • काली (रेगुर) मिट्टी नमी रोकती है, सूखने पर फटती है और कपास के लिए उपयुक्त है (दक्कन)।
  • लाल मिट्टी का रंग लौह ऑक्साइड से आता है; लैटेराइट अधिक वर्षा वाले क्षेत्रों में निक्षालन से बनती है और चाय, कॉफ़ी तथा काजू के लिए उपयुक्त है।
  • शुष्क मिट्टियाँ रेतीली और लवणीय हैं; वन और पर्वतीय मिट्टियाँ ऊँचाई के साथ बदलती हैं।
  • ICAR भारतीय मिट्टियों को आठ प्रमुख समूहों में बाँटता है।
  • चावल को उच्च तापमान और वर्षा चाहिए; गेहूँ ठंडी, शुष्क दशाओं की रबी फ़सल है।

व्याख्या

  • जूट मुख्यतः गंगा–ब्रह्मपुत्र डेल्टा में उगता है।
  • चाय अच्छी जल-निकासी वाली ढलानों पर उगती है (असम, दार्जिलिंग, नीलगिरि)।
  • कॉफ़ी मुख्यतः कर्नाटक में उगाई जाती है।
  • खरीफ़ फ़सलें मानसून के साथ बोई जाती हैं; रबी सर्दियों में; ज़ायद गर्मियों में।
  • मृदा अवनयन: अपरदन, लवणता, जलभराव।

चरण-दर-चरण

  1. पूछी गई अवधारणा, विधि या नीति पहचानें।
  2. परिभाषा, विचारक, वर्ष या नियम याद करें।
  3. उसे स्थिति पर लागू करें और अतिवादी विकल्प हटाएँ।

उदाहरण

  • कथन: "काली मिट्टी कपास के लिए आदर्श है।" → सही।
  • कथन: "लैटेराइट मिट्टियाँ कम वर्षा वाले क्षेत्रों में बनती हैं।" → गलत (अधिक वर्षा, निक्षालन)।
  • कथन: "गेहूँ खरीफ़ फ़सल है।" → गलत (रबी)।

ग़लतियों से बचें और उन्नत बिंदु

  • सामान्य भूल: लैटेराइट और लाल मिट्टी को मिला देना।
  • सामान्य भूल: गलत फ़सल ऋतु।
  • सामान्य भूल: जलोढ़ मिट्टी को सीमित कहना।

त्वरित पुनरावृत्ति

  • जलोढ़ सबसे व्यापक; काली → कपास।
  • लैटेराइट: निक्षालन।
  • खरीफ़, रबी, ज़ायद।

    3. Alluvial soils are widespread in river plains but vary in age and texture.
    4. Local winds may arise from thermal or topographic contrasts and can differ sharply from planetary wind systems.
