Very helpful
I read from other sources that- "Desertification does not refer to the expansion of existing deserts." It is degradation of land not transportation of desert sand to other places.

How can discouraging ground water usage prevent soil salinity, when the reason of salinity is increasing water table due to over accumulation of water ?
@prajwalshetty2228

Priyanka Gupta as most of ground water is saline,the usage of the same will onlh get it upwards where it increases salinity of upper not so saline layers.

Prajwal Shetty actually it's the other way round. Ground water is mostly not saline that's why it is used for drinking and irrigation. Water in the top soil is mostly saline.
@shashwatkant3443

Discouraging ground water usage in drought prone areas is the point here. Due to capilary action water rises up the surface, but due to excessive heat and high rate of evaporation, water content in the soil decreases rapidly due to which the concentration of residual salts and other dissolved minerals increases, making the soil saline and in-turn increasing it's rate. (I hope i am correct)
Nice mam

BARC me ek plant taiyyar kiya hai jo nitrogen fixing k saath salinity bhi reduce karta hai..mrunal has mentioned that in BES16 agriculture videos.You can search about that plant. Plus aap gypsum ka use kar sakte ho to remove salinity and flodd irrigation band kar dena and sprinker ya rain gun method se farming karo.

Desertification is a slightly different phenomenon. Study it from a different source.
Thanks a lot for proving us these high quality videos.

maam...excellent videos......one question though....how can the soil become acidic in leaching process when fe+al remain in the top soil....because metals are basic in nature.....i will be grateful if u can clarify this doubt.

They form iron and aluminum hydroxides by combining with water. They take up the hydrogen from water leaving a h ion free. I ll leave the rest for you to solve.
But, a machine harvesting might b a challenging task in a "Relay farming" ,isn't it ?

Should not it be Weathering responsible for Soil formation instead of Erosion ?

desertification is NOT expansion of desert @41.16
@deeprahul6564
7 жыл бұрын
it is an inferred statement. Because soil becomes infertile and not fit for agriculture thus making the land like a desert. Hence in a way the desert expanded.
Can you please improve the quality of the slides?? Otherwise the quality of teaching is too good.
