Laterite is a soil type rich in iron and aluminium and is commonly considered to have formed in ... laterite soils lack in fertility in comparison to other soils, ...
Red laterite soils in Tamil Nadu, Andhra Pradesh and Kerala are more suitable for crops like cashew nut. The laterite soil develops in areas with high temperature and heavy rainfall. This is the result of intense leaching due to heavy rain. The name "Laterite" is derived from the Latin word "later" which means a brick. Its red colour is due to ...
Oxisols are a soil order in USDA soil taxonomy, best known for their occurrence in tropical rain forest within 25 degrees north and south of the Equator. In the World Reference Base for Soil Resources (WRB), [1] they belong mainly to the ferralsols, but some are plinthosols or nitisols. Some oxisols have been previously classified as laterite ...
Acidifying N fertilizers create micro-sites around the granule that keep micronutrient cations soluble for longer in alkaline soils, but high concentrations of P or C may negate these effects. Boron deficiencies effecting seed yields and pollen fertility are common in laterite soils. [45]
Soil fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent yields of high quality. [3] It also refers to the soil's ability to supply plant/crop nutrients in the right quantities and qualities over a sustained period of time.
[7] [8] The soils in the region are reddish brown or brown soils of the pH range of 6.0 – 7.0. [9] The main crops grown in the region are millet, sorghum, and cowpea, while groundnut and sesame are significant minor crops. [10] Wild foods also serve as an important supplement to the diet, especially during times of food shortage. [10]
The Khoai can only support certain types of plants. It is a very poor soil for most types of agriculture practiced in the areas in which it is found. Yet often, a khoai maybe situated adjacent to a naturally forested area. Although a large area in Birbhum is covered by laterite, the areas where the laterite is exposed is termed as Khoai.
[3] [4] Khadir soil consists of new alluvial soil relatively higher in new silt content from the river, gets replenished with each flooding cycle, and is often very fertile. [ 4 ] The Khadir is also called Nali in the northern Haryana which is the fertile prairie tract between the Ghaggar river and the southern limits of the Saraswati channel ...
