Kala shiras" is a term used in India, particularly in Maharashtra, to refer to a specific type of black soil. "Kala" means "black" in Marathi, and "shiras" is often used to describe a region or a specific type of soil. This black soil, also known as Regur soil or black cotton soil, is rich in minerals like iron, magnesium, and aluminum. It is particularly suitable for growing cotton and various other crops due to its moisture-retaining capacity and fertility.
