The surface of this soil is sandy. It is rich in potash content but lacks phosphate, humus and nitrogen content. It is poor in phosphorus, nitrogen and lime. The green spike to dry spike ratio is around 10:1. Laterite soil is one of the valuable sources for building material, as it can be easily cut with a spade but hardens like iron when exposed to air. At higher elevations, lower temperature limits the crop growth. The cracks permits oxygenation of the soil to sufficient depths and the soil has extraordinary fertility.
There is also an off-shoot pun intended of this called aeroponics where the roots are grown naked in specially designed tubes or reservoirs and sprayed intermittently with a nutrient-rich water solution which is again recycled. It is highly suitable for agriculture, especially for crops such as paddy, sugarcane and plantain. Cotton growing is known as less mechanised farming in India so needs cheap labour. Laterite Soil Laterite soil is rich in aluminium and iron, formed in wet and hot tropical areas. India is one of the popular and well-known countries and this country has many witnesses, climatic and other natural circumstances. The reddish-yellow occurs due to the occurrence of iron oxides. Some mountain regions and plateau are also found with the alluvial oil.
These types of soils constitute about 10 to 40% of the organic matter and also a reasonable amount of soluble salts. Based on soil test results, farmers can choose appropriate manures and fertilizers for better crop yields. There are some theories has been put forward regarding the origin of this group of the soil but most of the scientist believe that the black soil have been formed because of the of lava. When the crop covers the broad interspaces at the time of manuring the weeds can be removed and manure can be spread in beds and earthed up. These soils are somewhat acidic in nature.
The colour of red soil is red due to the high iron content. There are many reason for this soil erosion. The insect attacks the healthy roots and sucks its sap. Sprouted barley is naturally high in maltose, a sugar that serves as the basis for both malt syrup sweetener. The former are sufficiently deep while the later are generally shallow.
Zaid Crop This crop is grown in some parts of country during March to June. They include the desert soils of western Rajasthan and mountain soils of the Himalayas. Basil flourishes well under fairly to high rainfall and humid conditions, and long days and high temperature have been found to be favourable for plant growth and higher oil production. Mexico did grow a lot of corn Maize then the Mexican government put price controls on corn. Indian tobacco is exported to about 100 countries.
Mathew, in , 2006 24. Every year this type of the soils is transformed. These soils are deficient of humus and moisture due to the fact that high evaporation in arid regions. Due to weathering, they release certain minerals such as magnesium, sodium, sulphurous acid and calcium salts. Data are given in a table format there.
In some hilly parts of Vishakapatnam district of Andhra Pradesh, long pepper is grown for its roots. Parent material usually rocks and the process of soil formation decide the soil properties. It is cultivated as a rainfed crop in Assam and Meghalaya and as an irrigated crop in other parts. For measuring soil pH, farmer can buy soil pH meters and check soil acidic levels. Black soil is rich in calcium, potassium and magnesium but has poor nitrogen content.
The most suitable soil for cultivation of wheat is well drained fertile loamy soil and clayey soil. Arid soils are saline in nature due to the high salt content and poor in nitrogen. Winter crops like wheat, gram, peas, and turnips emerged at 5Â°C but the percent emergence was low. Deep, well-drained sandy or sandy-loam soil is optimal. This soil is acidic with low humus and is found in Assam, Darjeeling, Kashmir, Uttranchal and Himachal Pradesh. An aridity index of 100% for a prolonged period of 5—10 weeks drastically affects productivity of coconut palms.
