Although alluvial soils are naturally poor in humus and nitrogen, they can still be fertile for agriculture for several reasons: High fertility of parent material: Alluvial soils are formed from sediment that is carried and deposited by rivers, which can include a variety of minerals and nutrients that are essential for plant growth. This means that alluvial soils can have high levels of other essential plant nutrients, such as phosphorus, potassium, and calcium. Good drainage: Alluvial soils are well-drained, which is important for growing crops that require a lot of water, such as rice. The good drainage of alluvial soils can also help to prevent waterlogging, which can be harmful to crops. Good aeration: Alluvial soils have a high level of porosity, which means that they have good air circulation, which is essential for healthy root growth and plant development. Good water retention: Alluvial soils have a high capacity to retain water, which can be beneficial for crops during periods of drought. Despite these advantages, alluvial soils can still benefit from the addition of organic matter and nitrogen-rich fertilizer to maintain their fertility and support the growth of crops. This can help to improve soil structure, increase the soil's capacity to hold water, and promote healthy plant growth. Voyager speaks why is alluvial poor in phosphorus Alluvial soils are often poor in phosphorus for several reasons: Soil erosion: Alluvial soils are formed from sediment that is carried and deposited by rivers and other bodies of water, which can lead to soil erosion. Erosion can remove phosphorus and other nutrients from the soil, reducing its fertility. Low organic matter: Alluvial soils are often low in organic matter, including humus, which is an important source of phosphorus. This can limit the amount of phosphorus available to plants. Chemical reactions: Phosphorus can be lost from soil due to chemical reactions that convert it into forms that are not readily available to plants. This can be particularly pronounced in alluvial soils, which are often alkaline and have high pH levels, which can lead to the formation of stable phosphorus compounds that are not available to plants. Adsorption: Phosphorus can also be lost from soil due to adsorption, which is the process by which nutrients are absorbed by the soil particles and become unavailable to plants. Alluvial soils have high levels of iron and aluminum oxide, which can adsorb phosphorus and limit its availability to plants. In summary, alluvial soils can be poor in phosphorus due to soil erosion, low organic matter, chemical reactions, and adsorption. To maintain their fertility, alluvial soils may require the addition of phosphorus-rich fertilizers to support healthy plant growth.
hii sir ,ur videos r really helpfull to me, can u cover chapter5 natural vegtation n plz upload videos of 12th std too it will really help me in my studies

Sir plz make separate lecture on economics and history also....no one can teach like you.. every doubt nd confusion became clear when I see ur lecture...plz hlp us sir..🙏
Sir one small correction in Laterite soil - iron oxide, aluminium compunds & potash are in excess (given in textbook) rest is fine :) Thank you very much for simplified explanation and all the videos :)
@ Amit, you are absolutely doing great work..very easy to understand....Will you be covering Chapter 7 "natural hazards" ? Also please cover "Human Geography" if possible. Thanks !
Sir,great description of everything..Could you please add a little recall or summary section at the end to recall everything we have gone thru the video:)Thanks for Noticing!
Hi Sir, Thanks for your videos as it made the concepts easy. I could see that in laterite soli, you mentioned it is poor in potash whereas in NCERT it is mentioned as laterite is excess in iron oxide and potash. can u pls confirm which is correct as i am confused with this? .
So Potash is nothing but a type of salt that contains Potassium. Now, Laterite soil is rich in iron oxide content and iron oxide is a base (alkali), it is not acidic. And usually most of the organic matters are basic in nature they are not acidic otherwise it will not be good for the plants. Now, Laterite soil lacks in Nitrogen, Potash, Potassium, Lime, Humus (a.k.a the organic matters). And these all have chemical properties of a base.

@@amitsengupta01 sir ji is this correct?
Decomposed vegetal and animal remains are called humus, which adds fertility to soil.
Sir Humus is not small microorganisms living under the soil rather the organic component of soil, formed by the decomposition of leaves and other plant material by soil microorganisms
Debashree Bal 😂
@@rklucky9657 i think there is nothing to laugh . She said right that was a little mistake of sir .
He prefers to shorten everything too much
The dead remains of organisms and plants help in humus accumulation.
But humus happens from microorganisms
