[16]:211, Angkor Wat—located in present-day Cambodia—is the largest religious structure built by Suryavarman II, who ruled the Khmer Empire from 1112 to 1152. [7] It seems this abrupt change was global and mainly represents an increase in ice mass; at about the same time an abrupt decrease in sea surface temperatures occurred; these two changes indicate a sudden global cooling. After rain, the water moves into the soil slowly. [15]:4 The Khmer people constructed the Angkor monuments—which are widely distributed in Cambodia and Thailand—between the 9th and 13th centuries. The residue (disturbed) laterite soil available after dressing of natural laterite building blocks was used, reddish brown in nature classified as A-2-7(0) using AASHTO soil classification system and GP by the United Soil … [5]:4 The reaction zone where rocks are in contact with water—from the lowest to highest water table levels—is progressively depleted of the easily leached ions of sodium, potassium, calcium and magnesium. [1]:65 He named it laterite from the Latin word later, which means a brick; this highly compacted and cemented soil can easily be cut into brick-shaped blocks for building. They develop by intensive and prolonged weathering of the underlying parent rock. [3]:1 The art of quarrying laterite material into masonry is suspected to have been introduced from the Indian subcontinent. [7] The rate of laterization would have decreased with the abrupt cooling of the earth. लैटराइट मिट्टी (Laterite) तथा मरु मिट्टी (desert soil)। भारतीय कृषि अनुसंधान परिषद (ICAR) ने भारत की मिट्टी को आठ समूहों में बांटा है: 33 or less 1.33 - 2.00 2. The majority of the land area containing laterites is between the tropics of Cancer and Capricorn. However, if the structure of lateritic soils becomes degraded, a hard crust can form on the surface, which hinders water infiltration, the emergence of seedlings, and leads to increased runoff. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. [24] The bauxites form elongate belts, sometimes hundreds of kilometers long, parallel to Lower Tertiary shorelines in India and South America; their distribution is not related to a particular mineralogical composition of the parent rock. [5]:3 Statistical analyses show that the transition in the mean and variance levels of 18O during the middle of the Pleistocene was abrupt. [17]:39 The sandstone used for the building of Angkor Wat is Mesozoic sandstone quarried in the Phnom Kulen Mountains, about 40 km (25 mi) away from the temple. Laterite ores also were the early major source of nickel. specializing in regolith development have considered that hopeless confusion has evolved around the name. Present-day laterite occurring outside the humid tropics are considered to be indicators of climatic change, continental drift or a combination of both. [19] Kenya, during the mid-1970s, and Malawi, during the mid-1980s, constructed trial sections of bituminous-surfaced low-volume roads using laterite in place of stone as a base course. [10], The mineralogical and chemical compositions of laterites are dependent on their parent rocks. [10] Rocks are leached by percolating rain water during the wet season; the resulting solution containing the leached ions is brought to the surface by capillary action during the dry season. [21]:1 The aquifer in this laterite recharges rapidly with the rains of April–May which follow the dry season of February–March, and continues to fill with the monsoon rains. Laterites are a source of aluminum ore; the ore exists largely in clay minerals and the hydroxides, gibbsite, boehmite, and diaspore, which resembles the composition of bauxite. (ख) सूक्ष्म वनस्पतिसमूह (microflora) जैसे काई या शैवाल (algae), डायटम (diatom), कवक, (fungi) ऐक्टिनोमाइसीज (actinomyces) आदि. [21]:4 It has considerable water-holding capacity, depending on the depth of the formation. [5]:1 The four main areas in the world with the largest nickel laterite resources are New Caledonia, with 21%; Australia, with 20%; the Philippines, with 17%; and Indonesia, with 12%. [9] They reach a maximum thickness of 30 m (100 ft) and once provided a major source of iron and aluminum ore.[9] Percolating waters caused degradation of the parent basalt and preferential precipitation by acidic water through the lattice left the iron and aluminum ores. [1]:65 Bauxite is a variety of laterite (residual sedimentary rock), so it has no precise chemical formula. [24] Many high-level bauxites are formed in coastal plains which were subsequently uplifted to their present altitude. [22] Percolating columns of laterite removed enough cadmium, chromium and lead to undetectable concentrations. a red soil produced by rock decay; contains insoluble deposits of ferric and aluminum oxides. It has also been used for any reddish soil at or near the Earth's surface.[2]. [5]:1 The discovery of sulfide deposits of Sudbury, Ontario, Canada, during the early part of the 20th century shifted the focus to sulfides for nickel extraction. [16]:210 Two types of laterite can be identified; both types consist of the minerals kaolinite, quartz, hematite and goethite. नोट ये मिट्टी सबसे ज्यादा केरल में पाई जाती है, पर्वतीय मिट्टी में कंकड़ एवं पत्थर की मात्रा अधिक होती है। पर्वतीय मिट्टी में भी पोटाश, फास्फोरस एवं चूने की कमी होती है। पहाड़ी क्षेत्र में खास करके बागबानी कृषि होती है। पहाड़ी क्षेत्र में ही झूम खेती होती है। झूम खेती सबसे ज्यादा नागालैंड में की जाती है। पर्वतीय क्षेत्र में सबसे ज्यादा गरम मसाले की खेती की जाती है।, शुष्क एवं मरूस्थलीय मिट्टी में घुलनशील लवण एवं फास्फोरस की मात्रा अधिक होती है। इस मिट्टी में नाइट्रोजन एवं कार्बनिक तत्व की मात्रा कम होती है। यह मिट्टी तेलहन के उत्पादन के लिए अधिक उपर्युक्त मानी जाती है। जल की व्यवस्था होने के बाद मरूस्थलीय मिट्टी में भी अच्छी फसल की उत्पादन होती है। इस मिट्टी में तिलहन के अलावा ज्वार, बाजरा एवं रागी की खेती होती है। [clarification needed][14], After 1000 CE Angkorian construction changed from circular or irregular earthen walls to rectangular temple enclosures of laterite, brick and stone structures. The mechanism of leaching involves acid dissolving the host mineral lattice, followed by hydrolysis and precipitation of insoluble oxides and sulfates of iron, aluminum and silica under the high temperature conditions[8] of a humid sub-tropical monsoon climate. [22] Calcium-, iron- and aluminum-rich solid media are recommended for phosphorus removal. [3]:1 In Madhya Pradesh, India, the laterite which caps the plateau is 30 m (100 ft) thick. [22] A pilot-scale experimental facility containing laterite achieved 96% removal of phosphorus. Sorry, no text. [5]:1 About 70% of the Earth's land-based nickel resources are contained in laterites; they currently account for about 40% of the world nickel production. 3H2O)] in newer tropical deposits; in older subtropical, temperate deposits the major minerals are boehmite [γ-AlO(OH) or Al2O3.H2O] and some diaspore [α-AlO(OH) or Al2O3.H2O]. Palms are less likely to suffer from drought because the rain water is held in the soil. [18], The French surfaced roads in the Cambodia, Thailand and Vietnam area with crushed laterite, stone or gravel. जलोढ़ मिट्टी में नाइट्रोजन एवं फॉस्फोरस की मात्रा कम होती है। यह कारण है कि जलोढ़ मिट्टी में यूरिया खाद डालना फसल के उत्पादन के लिए आवश्यक होता है। जलोढ़ मिट्टी में पोटाश एवं चूना की पर्याप्त मात्रा होती है। [9], Laterite ores were the major source of early nickel. [24], The basaltic laterites of Northern Ireland were formed by extensive chemical weathering of basalts during a period of volcanic activity. Locally available laterites have been used in an acid solution, followed by precipitation to remove phosphorus and heavy metals at sewage-treatment facilities. [3]:2 One example is the Southwestern Laterite (Cabook) Aquifer in Sri Lanka. [3]:6 Laterites consist mainly of quartz, zircon, and oxides of titanium, iron, tin, aluminum and manganese, which remain during the course of weathering. Laterite is both a soil and a rock type rich in iron and aluminum and is commonly considered to have formed in hot and wet tropical areas. [21]:10, In Northern Ireland, phosphorus enrichment of lakes due to agriculture is a significant problem. Since the mid-1970s, some trial sections of bituminous-surfaced, low-volume roads have used laterite in place of stone as a base course. (right-side chat box appearing with Red header.)] [22] A study, using both laboratory tests and pilot-scale constructed wetlands, reports the effectiveness of granular laterite in removing phosphorus and heavy metals from landfill leachate. Meaning of laterite. [10] A solution of these ions can have the correct pH to preferentially dissolve silicon oxide rather than the aluminum oxides and iron oxides. Chat directly with admin !! [5]:3, Laterites are formed from the leaching of parent sedimentary rocks (sandstones, clays, limestones); metamorphic rocks (schists, gneisses, migmatites); igneous rocks (granites, basalts, gabbros, peridotites); and mineralized proto-ores;[3]:5 which leaves the more insoluble ions, predominantly iron and aluminum. [5]:1 In 1950 laterite-source nickel was less than 10% of total production, in 2003 it accounted for 42%, and by 2012 the share of laterite-source nickel was expected to be 51%. भारत में उत्तर का मैदान (गंगा का मैदान) सिंध का मैदान, ब्रह्मपुत्र का मैदान गोदावरी का मैदान, कावेरी का मैदान नदियों जलोढ़ मिट्टी के निक्षेपण से बने है। जलोढ़ की मिट्टी गेहूँ के फसल के लिए उत्तम माना जाता है। इसके अलावा इसमें धान एवं आलू की खेती भी की जाती है। जलोढ़ मिट्टी का निर्माण बलुई मिट्टी एवं चिकनी मिट्टी के मिलने से हुई है। जलोढ़ मिट्टी में ही बांगर एवं खादर मिट्टी आते है। बांगर पुराने जलोढ़ मिट्टी को एवं खादर नये जलोढ़ मिट्टी को कहा जाता है। जलोढ़ मिट्टी का रंग हल्के धूसर रंग का होता है।, काली मिट्टी क्षेत्रफल की दृष्टिकोण से भारत में दूसरा स्थान रखता है। भारत में सबसे ज्यादा काली मिट्टी महाराष्ट्र में एवं दूसरे स्थान पर गुजरात प्रांत है। काली मिट्टी का निर्माण ज्वालामुखी के उदगार के कारण बैसाल्ट चट्टान के निर्माण होने से हुई। बैसाल्ट के टूटने से काली मिट्टी का निर्माण होता है। दक्षिण भारत में काली मिट्टी को 'रेगूर' (रेगूड़) कहा जाता है। केरल में काली मिट्टी को 'शाली' कहा जाता है। उत्तर भारत में काली मिट्टी को 'केवाल' के नाम से जाना जाता है।, काली मिट्टी में भी नाइट्रोजन एवं फॉस्फोरस की मात्रा कम होती है। इसमें लोहा, चूना, मैग्नीशियम एवं एलूमिना की मात्रा अधिक हाती है। काली मिट्टी में पोटाश की मात्रा भी पर्याप्त होती है।, काली मिट्टी कपास के उत्पादन के लिए सबसे उत्तम मानी जाती है। इसके अलावा काली मिट्टी में चावल की खेती भी अच्छी होती है। काली मिट्टी में मसूर, चना, खेसाड़ी की भी अच्छी उपज होती है।, काली मिट्टी में लोहे की अंश अधिक होने के कारण इसका रंग काला होता है। काली मिट्टी में जल जल्दी नहीं सुखता है अर्थात इसके द्वारा अवषोषित जल अधिक दिनों तक बना रहता है, जिससे इस मिट्टी में धान की उपज अधिक होती है। काली मिट्टी सुखने पर बहुत अधिक कड़ी एवं भीगने पर तुरंत चिपचिपा हो जाती है। भारत में लगभग 5.46 लाख वर्ग किमी0 पर काली मिट्टी का विस्तार है।, क्षेत्रफल के दृष्टिकोण से भारत में लाल मिट्टी का तीसरा स्थान है। भारत में 5.18 लाख वर्ग किमी0 पर लाल मिट्टी का विस्तार है। लाल मिट्टी का निर्माण ग्रेनाइट चट्टान के टूटने से हुई है। ग्रेनाइट चट्टान आग्नेय शैल का उदाहरण है। भारत में क्षेत्रफल की दृष्टिकोण से सबसे अधिक क्षेत्रफल पर तमिलनाडु राज्य में लाल मिट्टी विस्तृत है। लाल मिट्टी के नीचे अधिकांश खनिज मिलते हैं।, लाल मिट्टी में भी नाइट्रोजन एवं फॉस्फोरस की मात्रा कम होती है। लाल मिट्टी में मौजूद आयरनर ऑक्साइड(Fe2O3) के कारण इसका रंग लाल दिखाई पड़ता है। लाल मिट्टी फसल के उत्पादन के लिए अच्छी नहीं मानी जाती है। इसमें ज्यादा करके मोटे अनाज जैसे- ज्वार, बाजरा, मूँगफली, अरहर, मकई, इत्यादि होते है। कुछ हद तक धान की खेती इस मिट्टी में की जाती है, लेकिन काली मिट्टी के अपेक्षा धान का भी उत्पादन कम होता है। तमिलनाडु के बाद छतीसगढ़, झारखंड, मध्यप्रदेश एवं उड़ीसा प्राप्त में भी लाल मिट्टी मिलते है।, पीली मिट्टी - भारत में सबसे अधिक पीली मिट्टी केरल राज्य में है। जिस क्षेत्र में लाल मिट्टी होते है एवं उस मिट्टी में अधिक वर्षा होती है तो अधिक वर्षा के कारण लाल मिट्टी के रासायनिक तत्व अलग हो जाते है, जिसमें उस मिट्टी का रंग पीला मिट्टी दिखाई देने लगता है।, भारत में क्षेत्रफल के दृष्टिकोण से लैटेराइट मिट्टी को चौथा स्थान प्राप्त है। यह मिट्टी भारत में 1.26 लाख वर्ग किमी0 क्षेत्र पर फैला हुआ है। लैटेराइट मिट्टी में लौह ऑक्साइड एवं अल्यूमिनियम ऑक्साइड की मात्रा अधिक होती है लेकिन नाइट्रोजन, फॉस्फोरस, पोटाष, चुना एवं कार्बनिक तत्वों की कमी पायी जाती है। लैटेराइट मिट्टी चाय एवं कॉॅफी फसल के लिए सबसे अच्छी मानी जाती है। भारत में लैटेराइट मिट्टी असम, कर्नाटक एवं तमिलनाडु राज्य में अधिक मात्रा में पाये जाते है। यह मिट्टी पहाड़ी एवं पठारी क्षेत्र में पाये जाते है। यह मिट्टी काजू फसल के लिए सबसे अच्छी मानी जाती है। इसमें लौह अॉक्साइड एवं अल्यूमिनियम ऑक्साइड की मात्रा अधिक होती है, लेकिन इस मिट्टी में नाइट्रोजन, फास्फोरस, पोटास एवं चूना की कमी होती है।, इस मिट्टी की भी रंग लाल होती है। जब वर्षा होती है तब इस मिट्टी से चूना-पत्थर बहकर अलग हो जाती है, जिसके कारण यह मिट्टी सुखने पर लोहे के समान कड़ा हो जाती है। Meaning: 1: ના લેટરાઇટ: ગરમ પ્રદેશોમાં ખડકોના ધોવાણના પરિણામે પડખે જામતી માટી Material that looks highly similar to the Indian laterite occurs abundantly worldwide. मिट्टी में अनेक जीवाणु, कीटाणु और जीवजंतु पाए जाते है, जो अनेक रासायनिक अभिक्रियाएँ संपन्न कर मिट्टी के गुण में परिवर्तन करते हैं। ये है: मिट्टी में जीवाणुओं का स्थान बड़े महत्व का है। इनसे मिट्टी के भौतिकगुण बदलते हैं और उसकी उर्वरता बढ़ती है।।, मिट्टी में बारीक कण कलिल (colloid) के रूप में रहते हैं। उन पर आयनों (ions) की विनिमय क्रिया होती है। यह क्रिया पौधों की जड़ों को पोषक द्रव्य पहुंचाने में सहायक होती है। इसलिये यह क्रिया बड़े महत्व की है। कलिल कार्बनिक और अकार्बनिक दोनों हो सकते हैं। ये दोनों परस्पर मिले रहते हैं। अकार्बनिक कलिल ऐल्यूमिना और सिलिका के योग से बनते हैं। सिलिका कलिल पर ऋण विद्युत् रहता है। ये धन आयन का अवशोषण करते है। धन आयन पोषक तत्व होता है। कार्बनिक कलिल जल और पोषक तत्व का अधिक अवशोषण करता है। कलिल ऋण आयन का भी अवशोषण करते हैं।, मिट्टी में अम्लता और क्षारीयता कलिल से उत्पन्न होती है। जब कलिल में क्षारीय तत्व अधिक रहता है तब क्षारीयता और हाइड्रोजन अधिक अवशोषित रहता है तब अम्लता, उत्पन्न होती है। अम्लता और क्षारीयता दोनों पौधों के लिये हानिकारक हैं। पौधों की अम्लता और क्षारीयता हाइड्रोजन आयन के सांद्रण से मापी जाती है। इसे पीएच द्वारा प्रकट करते हैं। यदि पीएच १ से ६ है, तो मिट्टी अम्लीय और ७ से ८.५ हो, तो लवणीय मिट्टी ८.५ से १४ है, तो मिट्टी क्षारीय होती है। विभिन्न पीएच पर तत्वों का अवशोषण विभिन्न होता है। अम्लता को दूर करने के लिये चूने या जिप्सम का प्रयोग होता है।, मिट्टी के रासायनिक और भौतिक विश्लेषण किए जाते हैं। रासायनिक विश्लेषण से मिट्टी के पोषक द्रव्यों का पता लगता है और भौतिक विश्लेषण से मिट्टी के कणों की स्थिति का ज्ञान होता है। रासायनिक विश्लेषण नाइट्रोजन, फॉस्फेट (पूर्ण और प्राप्य), पोटाश (पूर्ण और प्राप्य) और जल की मात्रा निर्धारित की जाती है।.
