Crop, Soil, and Watershed Management

Agronomy is best described as the science and practice primarily concerned with:

Grain legumes (pulses) are agriculturally significant partly because they:

Intercropping is defined as:

Crop rotation, which commonly includes a legume in the sequence, primarily helps to:

Photoperiod sensitivity in certain crops refers to their response to:

In Nepal's cropping calendar, rice and maize are typically classified as:

Tuber crops such as potato and sweet potato are grown primarily for their:

Matching crop choice to the local agro-climatic zone is fundamental mainly because:

Rice cultivation commonly involves which distinctive land/crop establishment practice compared to upland cereals like wheat?

Fruit and plantation crops (e.g. citrus, tea) differ from annual field crops mainly in that they:

Textural classification of soil is based primarily on:

Alluvial soils, common in Nepal's Terai region, are formed primarily by:

Colluvial soils, common on hill slopes, are primarily formed by:

Soils of the Siwalik/Chure foothills are generally characterized as:

Cation exchange capacity (CEC) of a soil describes its ability to:

Soil bulk density and porosity are classified as which category of soil property?

Soil microorganisms (bacteria, fungi, actinomycetes) primarily contribute to soil fertility by:

Mid-hill soils in Nepal are typically found on which characteristic land form, influencing their management?

Soil organic matter content is classified as which type of soil property?

Systematic soil classification systems such as USDA Soil Taxonomy group soils based primarily on:

Nitrogen deficiency in crops is commonly characterized by:

Potassium (K) deficiency in crops is typically characterized by:

Micronutrient deficiencies (e.g. iron, zinc) most commonly present as:

The gravimetric method for measuring soil moisture is considered:

Tensiometers and capacitance/TDR probes are used in the field primarily to measure:

Electrical conductivity (EC) measurement of a soil-water extract primarily indicates:

The Walkley-Black method is commonly used in soil testing to determine:

Soil pH is important to measure primarily because it:

Green manuring, as a cultural practice to improve soil fertility, involves:

Indigenous knowledge in soil fertility management, such as traditional composting and terracing practices, is particularly valuable because it:

Soil conservation priorities in Nepal's mid-hills are most centrally focused on:

Land capability classification categorizes land primarily according to:

In the Universal Soil Loss Equation (USLE), the 'K' factor represents:

The 'P' factor in the USLE/RUSLE equation accounts for:

Field plot (runoff plot) studies are primarily used to:

Erosion pins are a monitoring tool used to measure:

Remote sensing/GIS-based change detection for erosion monitoring primarily works by:

Land unsuited to cultivation under a land capability classification scheme is typically recommended for:

Conservation concerns in Nepal's high mountains are particularly centered on:

The 'LS' factor in the USLE equation combines the effects of:

A key triggering mechanism for landslides is:

A 'land slip' is best described as: layer beneath

A debris flow is distinguished from a typical landslide mainly by:

Surface and sub-surface drainage as a landslide control measure functions primarily by:

Sheet erosion is characterized by:

Gully erosion differs from rill erosion primarily in that: erosion

Biological/cultural measures for controlling soil erosion primarily work by:

Check dams (gully plugs) are structural erosion-control measures that function by:

Bioengineering techniques (e.g. brush layering, live check dams) for slope stabilization are valued particularly because they: vegetation establishes

Loss of vegetative cover and root reinforcement on a slope generally: increasing infiltration

In the hierarchical classification of watersheds by size, which is generally the largest unit?

Prioritization of watersheds for conservation intervention typically considers: intervention

Watershed management is best described as taking:

Contour farming/bunding, as a soil moisture management practice, primarily functions by:

Water harvesting is defined as: recharge

A conservation pond, as distinct from a general farm pond, is primarily designed to:

Water recycling within a farm/watershed system refers to: secondary uses

Community-based user groups (e.g. watershed/forest user groups) play a role in Nepal's watershed management primarily by:

Watershed management planning typically begins with:

Participatory involvement of local communities in watershed management planning is valued primarily because it:
