Statement 1: Conservation tillage is less applicable to high-input level crop production. Statement 2: The topsoil is not inverted in conservation tillage.
Statement 1: Class II land is denoted by the color yellow. Statement 2: Class II land has very few or no limitations that restrict its use.
Which of the following is an advantage of contour farming?
Statement 1: 20-25 % of soil erosion is carried out by surface creep. Statement 2: 3-4 % of soil erosion is by suspension.
Statement 1: Badlands, rock outcrops, sandy beaches, marshes & deserts are included in class VIII land. Statement 2: Class VIII land has a high steepness > 35 %.
Which of the following does NOT come under conservation tillage?
Statement 1: Sheet erosion is also known as the "death of farmers." Statement 2: Channelization begins from sheet erosion.
Which of the following is NOT a feature of mulching?
Statement 1: Agronomic interventions are adopted where the land slope is < 2 %. Statement 2: Contour farming & conservation farming come under agronomic measures.
Statement 1: Contour strip cropping widens the length of the slope and checks the movement of runoff water. Statement 2: Moth bean & horse gram are the most efficient crops to check soil erosion.
Class V land is denoted by the color --------.
The removal of soil particles due to raindrops is called __________ erosion.
Ravines are a prolonged & advanced stage of gully erosion and are found in _________.
In surface creep, soil particles are larger than about 0.5 mm in diameter but smaller than ______ mm.
Statement 1: Deep tillage is beneficial for all crops. Statement 2: Subsoiling can be beneficial, either to increase the porosity of the soil or to break a pan, which increases permeability.
In suspension, very fine particles _______ are carried into the air.
Particles too heavy to be moved in saltation are rolled and slide along the surface by wind, hitting the surface during ___________________.
Statement 1: Mixed cropping is growing 2 or more crops simultaneously in the same field with a definite row pattern. Statement 2: Mechanical measures are adopted when the land slope is > 2 %.
Statement 1: Soils in class VI have continuing limitations that can be corrected. Statement 2: The land slope of class VI varies from 15-25 %.
Which type of strip cropping is used on land that is steep, highly eroded, or unfit for regular rotation?
How many soil movement processes are there in wind erosion?
Which of the following is NOT a preferred cover crop generally?
Landslide or slip erosion takes place if the slope is __________.
Strip cropping is mainly divided into _____ types.
Statement 1: Strip cropping is a system of growing parallel strips of erosion-permitting crops & erosion-resisting crops in the same field. Statement 2: Erosion-resisting crops are moth bean & groundnut.
About __________ of soil erosion by wind is carried out by saltation.
Which of the following options is the last stage of water erosion?
Which land capability class has moderate limitations that reduce the choice of plants or require special conservation practices?
Statement 1: Soil carried in saltation consists of fine particles ranging from 0.1 to 0.5 mm in diameter. Statement 2: Soil carried by the wind, moved in a series of short bounces, is called suspension.
Statement 1: Grassed waterways are constructed across the slope of the land. Statement 2: Grass waterways may be natural or constructed.
