Laterite soil is poor in oxides of which among the following?

Explanation

The correct answer is Silicon. Key Points Laterite soil is reddish to yellow, with low levels of potassium, phosphorus, nitrogen, lime, and magnesia, and high levels of aluminium, iron, titanium, and manganese oxides (90 to 100 per cent). HenceLaterite soil is poor in oxides in Silicon. The Red colour is due to iron oxide present in the Laterite soil. Laterite soil is formed as a result of high leaching. Laterite soil is deficient in Nitrogen, Potash, Potassium, Lime, and Humus. Rice, Ragi, Sugarcane, and Cashew nuts are mainly cultivated in Laterite Soil. The humus content is low in Laterite Soil. Additional Information Soil is one of the most important natural resources. Soil is the mixture of rock debris and organic materials which develop on the earth’s surface. It provides anchorage to the plants and supplies water and nutrients. Soil is essential for agriculture. Soil is of different types: clayey, loamy and sandy.
