धान की उपज में वृद्धि के लिए सिलिकॉन का महत्व Silicon (Si) is next to oxygen (O) in quantity on earth’s crust. Silicon in combination with oxygen forms silicon dioxide (SiO2) which is also known as silica. About 87% of the earth’s surface is made up of silica. There are 200 over types of silicate rocks in nature. These include quartz and mica. The white mica is made up of silicon, potassium and aluminum whereas the black mica contains iron and magnesium. The original soil minerals are predominantly silicate compounds. The silicon in sand, silt, and clay is extremely insoluble and difficult to be absorbed by plant. However, under the reaction of soil...

समस्याग्रस्त मिट्टी का प्रबंधन कैसे करें For the management of problematic soils,  some general principles has to be considered for proper implementation of the reclamation measures. The total soluble salt concentrations in the root zone have to be decreased to control osmotic effects on plant growth. Maintenance of total soil moisture tension must be ensured at optimum level so that plant roots can absorb an adequate amount of water. Water flows through the soil in the direction of maximum decrease of hydraulic head and the flow velocity is proportional to the hydraulic gradient. The design and layout of drainage system are controlled by this principle. The availability of good quality water is of paramount for...

सेलाइन (खारा) मिट्टी के सुधार की तकनीक Accumulation of excess salts in the root zone resulting in a partial or complete loss of soil productivity is a worldwide problem. Soil salinity has caused heavy loss of national wealth in India. Out of 329 million hectares of land in the country, about 175 million ha (53 %) is suffering from degradation. The extent of this problem area as given by different sources varies from 8.56 M ha to 10.9 M ha. According to Central Soil Salinity Research Institute (CSSRI), Karnal, 1.7 M ha of land is affected by salinity among the 6.7 M ha of salt affected land. World as a whole is...
