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...

भारत की मृदा व फसलों में बोरोन तथा मोलिब्डेनम की कमी और उर्वरकों के प्रयोग सेे उनमे सुुुुधार   Plants require eight micronutrients for their growth and development. Out of them, Boron (B) and Molybdenum (Mo) are anionic micronutrients found to be deficient in Indian soils and crops. The essentiality of the B and Mo for higher plants was first established by K. Warington in 1923 and by D. I. Arnon and P. R. Stout in 1939 respectively. The information regarding deficiency of B and Mo in soils in India, their role in plant growth and deficiency symptoms and fertilizers containing B and Mo for amelioration is being provided for the benefit...
