Soil texture and organic matter are the key components that determine soil water-holding capacity. Organic matter influences the physical conditions of a soil in several ways. Plant residues that cover the soil surface protect the soil from sealing and crusting by raindrop impact, thereby enhancing rainwater infiltration and reducing runoff. Each 1 per cent increase in soil organic matter helps soil hold 20,000 gallons more water per acre.<\/li><li><strong>Statement 2 is not correct:<\/strong> Sulphur is one of three nutrients that are cycled between the soil, plant matter and the atmosphere. The sulphur cycle describes the movement of Sulphur through the atmosphere, mineral and organic forms, and through living things. Although Sulphur is primarily found in sedimentary rocks, it is particularly important to living things because it is a component of many proteins. Hence, soil plays a role in the Sulphur cycle.<\/li><\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/edukemy.com\/free-resources-for-upsc?utm_source=Blog&amp;utm_medium=Banner&amp;utm_campaign=Resources\" target=\"_blank\" rel=\"noreferrer noopener\"><img decoding=\"async\" width=\"1280\" height=\"300\" data-src=\"https:\/\/edukemy.com\/blog\/wp-content\/uploads\/2024\/06\/18.png\" alt=\"\" class=\"wp-image-42398 lazyload\" data-srcset=\"https:\/\/edukemy.com\/blog\/wp-content\/uploads\/2024\/06\/18.png 1280w, https:\/\/edukemy.com\/blog\/wp-content\/uploads\/2024\/06\/18-1170x274.png 1170w, https:\/\/edukemy.com\/blog\/wp-content\/uploads\/2024\/06\/18-585x137.png 585w\" data-sizes=\"(max-width: 1280px) 100vw, 1280px\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" style=\"--smush-placeholder-width: 1280px; --smush-placeholder-aspect-ratio: 1280\/300;\" \/><\/a><\/figure>\n\n\n\n<p>For UPSC Prelims Resources,&nbsp;<a href=\"https:\/\/edukemy.com\/upsc-cse-prelims-resource-centre\" target=\"_blank\" rel=\"noreferrer noopener\">Click here<\/a><\/p>\n\n\n\n<p>For Daily Updates and Study Material:<\/p>\n\n\n\n<p>Join our Telegram Channel \u2013&nbsp;<a href=\"https:\/\/t.me\/WithEdukemy4IAS\" target=\"_blank\" rel=\"noreferrer noopener\">Edukemy for IAS<\/a><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>1.
