What is meant by laterite soil?
Laterite, soil layer that is rich in iron oxide and derived from a wide variety of rocks weathering under strongly oxidizing and leaching conditions.
It forms in tropical and subtropical regions where the climate is humid..
What are the advantages and disadvantages of laterite soil?
2. They have high clay content, hence better water holding capacity. 3….Disadvantages :These Soils are formed by leaching , therefore consists of less minerals and organic materials .They are acidic in nature.They are very poor fertile .They have high clay content and lower cation exchange capacity.
What is black soil rich in?
Chemically, the black soils are rich in lime, iron, magnesia and alumina. They also contain potash. But they lack in phosphorous, nitrogen and organic matter.
What grows well in black cotton soil?
Black soil is rich in chemical properties and very suitable for the growth of cotton, jowar, wheat, linseed, ground nut and gram. In horticulture crops – Mango, Sapota, Guava and Banana are main fruit crops and vegetables like Peas, Brinjal, Tomato, Green chilli etc. are grown.
What are the factors responsible for the formation of soil?
Scientists attribute soil formation to the following factors: Parent material, climate, biota (organisms), topography and time.
Why is black soil suitable for growing cotton?
Black soil is ideal for growing cotton and is also known as black cotton soil. These soils are made up of extremely fine i.e. clayey material. They are well-known for their capacity to hold moisture.
What is black soil used for?
Because of their high fertility and retentivity of moisture, the black soils are widely used for producing several important crops. Some of the major crops grown on the black soils are cotton, wheat, jowar, linseed, Virginia tobacco, castor, sunflower and millets.
What are the advantages and disadvantages of black soil?
The advantage of black soil is that it has high moisture content & also full of organic matter making it suitable to grow plantation crops as cotton, tobbaco ,sugarcane. The disadvantage is that it becomes sticky when wet, it becomes difficult for ploughing so it should be ploughed before raining.
What is another name for black soil?
black soils known locally as regur. After those the alluvial soil is the third most-common type.
Where is black soil found?
Black soils are derivatives of trap lava and are spread mostly across interior Gujarat, Maharashtra, Karnataka, and Madhya Pradesh on the Deccan lava plateau and the Malwa Plateau, where there is both moderate rainfall and underlying basaltic rock.
What are the three characteristics of black soil?
It develops cracks during hot weather. Iron content present in this soil turns into iron oxide due to diffusion. It’s made of fine clay particles. It retains moisture for long.
Is black soil acidic or alkaline?
The soil is rich in clay (montmorillonite) particles and has neutral to slightly alkaline reaction. The soil is rich in bases, lime and calcium. The pH of black soil is 7.2 – 8.5. The soil is deficient in nitrogen, phosphate and organic matter but rich in potash, calcium and magnesium.
Why is black soil fertile?
The black soils are also called as regur are fertile because they are highly moisture retentive, more clay content,which responds well to irrigation. The black soils are argillaceous contains many essential nutrients along with some content of humus as well.
What is black cotton soil?
Black cotton soils are clay rich soils formed in regions (tropics and subtropics) having poor drainage conditions. Such conditions favour the formation of such clays which have montmorillonite clay mineral as the principal clay mineral.
Is black soil good for plants?
Dark, rich, loamy soil does support many crops much better than sandy or clay soils. … Black soil has the advantage of lots of nutrients that plants need, and it retains moisture very effectively, making it a great growing medium for most plants, but that doesn’t mean it is the best soil for farming.
Which factors are responsible for the formation of black soil?
(1) Climatic conditions like temperature, rainfall etc. along with present rock material are important factors for making of black soil. The parent rock is volcanic rock.
What are the disadvantages of black soil?
Besides advantages of black soil, there are some disadvantages or problems of black soil. Those are listed below. Cracking when dry and swelling when wet makes them difficult to manage, unless they are cultivated at appropriate soil moisture levels. This makes black soil difficult to manage.
What are the advantages and disadvantages of alluvial soil?
They are very humus rich in nature and are fertile. They are rich in potassium and are highly suitable for the agriculture. The main disadvantage of alluvial soil are: They are sandier in nature that makes them not so ideal since they will drain water at a faster rate.
