The soils of the Punjab and Haryana plains belong to the alluvial class typical of the Indo-Gangetic plains. A majority of the soils are loams or sandy loams, with a soil crust of varying depth. Hardly any profile characteristics are observed. Soluble salts are present in considerable quantities. The lower layers contain *kankar* nodules. The soil character is generally alkaline due to the presence of sodium in the clay complex. The soils are rich in phosphorus and potash, but are deficient in organic matter and nitrogen.
