Q401. Which one of the following rivers does not originate in India?
👁 0 viewsQ402. National Water Way - 1 connects:
👁 0 viewsStates through it passes are Uttar Pradesh, Bihar, Jharkhand & West Bengal.
Q403. River Ganga, after entering Bangladesh is known by which of the following names?
👁 0 viewsQ404. Leaching is the maximum in the soil type of:
👁 1 viewsLeaching is the process of soluble materials being washed out from the soil by percolating water. It is most intense in hot, very humid climates with heavy rainfall, where water moves quickly through the soil profile. Laterite soils form under such conditions and experience maximum leaching, removing silica and soluble bases, leaving iron and aluminum oxides. Red and Regur soils are less leached, while Desert soils have minimal leaching due to low rainfall.
Laterite soil is typically rich in iron and aluminum oxides and is often hard when baked by the sun.
Leaching is highest in laterite soils due to heavy rainfall and intense percolation.
Q405. Red soil colour is caused by:
👁 0 viewsQ406. In soil, water that, is readily available to plant roots is:
👁 1 viewsCapillary water is the water held in the small pores of soil by capillary forces and is accessible to plant roots. It fills the space between soil particles in pore spaces and remains available after gravitational drainage. Gravitational water drains quickly due to gravity, hygroscopic water is tightly bound to soil particles and not readily available, and bound water is generally unavailable to plants. Thus, capillary water is the readily available moisture that plants can uptake to a significant extent.
Capillary water availability varies with soil texture; loamy soils usually hold more readily available water than coarse sands.
Capillary water is the soil moisture retained in pores and accessible to plants; not gravitational, hygroscopic, or bound water.
Q407. Which of the following statements relating to Indian agriculture is/are correct ? 1. India has the World’s largest cropped area. 2. Cropping pattern is dominated by cereal crop. 3. The average size of an Indian farm holding is too small for several agricultural operations. Select the correct answer using the code given below :
👁 2 viewsCorrect answer is D: all three statements are true. India has the world's largest cropped area in terms of area under annual crops, cropping pattern is dominated by cereal crops (like rice and wheat), and the average size of Indian farm holdings is small, leading to many farms facing constraints in implementing large-scale agricultural operations. Together, these facts reflect the scale of cultivation, the cereal-led pattern, and the small, fragmented landholdings that characterize Indian agriculture. Options 1 or 2 alone omit other essential aspects, while 3 alone misses the extent of cropping area and cereal dominance.
India's rural economy relies heavily on farming and related activities, with a large portion of rural households dependent on agriculture for livelihood.
India has a very large cropped area, cereals dominate the cropping pattern, and farm holdings are generally small.
Q408. Which one of the following statements is not correct?
👁 1 viewsThe statement A is incorrect. Lime (calcium carbonate) is added to acidic soils to raise pH and reduce acidity. In acidic soils, lime neutralizes hydrogen ions, making the soil less acidic (more alkaline). The other statements are correct: humid climates promote leaching and higher soil acidity; increasing acidity reduces essential nutrient availability, lowering fertility; arid climates often have alkaline soils due to evaporation concentrating bases.
Soil pH greatly influences nutrient availability; most crops prefer near-neutral pH for optimal uptake of major nutrients like N, P, K.
Lime is used to reduce soil acidity by raising pH, not to make soil acidic.
Q409. Leaves of which of the following plants are not used for the rearing of silkworms?
👁 0 viewsQ410. Mulching, an agronomic measure of soil conservation, is very effective because it: 1. protects soil from gully erosion 2. protects soil from sheetwash and wind erosion 3. helps soil to retain moisture and nutrients Select the correct answer using the code given below.
