Question:
In agroforestry, SALT cultivation system is called ___________.
In agroforestry, SALT cultivation system is called ___________.
Show Hint
SALT was developed in the late 1970s by the Mindao Baptist Rural Life Center in the Philippines.
It is an effective soil conservation technology that can reduce soil erosion on steep slopes by over \(90\%\).

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Sloping Agricultural Land Technology (SALT) is an agroforestry system developed in the Philippines to control soil erosion, restore soil fertility, and improve crop yields on hilly, sloping lands.
Step 2: Detailed Explation:
The SALT system is a specific form of contour hedgerow intercropping.
In this system, double rows of fast-growing, nitrogen-fixing woody shrubs or trees (such as Leucae leucocephala, Gliricidia sepium, or Calliandra calothyrsus) are planted along established contour lines across the hillslope.
These dense hedgerows act as physical barriers that slow down water runoff and trap eroding soil, turally forming terraces over time.
The alleys between the hedgerows are used to cultivate annual agricultural crops (like maize or upland rice) and perennial crops.
The hedgerows are periodically pruned, and the prunings are applied to the alleys as mulch and green manure to enrich the soil.
Therefore, the SALT system is classified as a contour hedgerow intercropping system.
Step 3: Fil Answer:
The correct option is (D).

Statement (I): Anogeissus latifolia is worked only as a component species of mixed forests as coppice-with-standards.
Statement (II): Terminalia arjuna tree is not a regular component of forest stand and is usually worked under selection and coppice with standards.
Choose the correct answer from the options given below: - The most important single factor affecting natural regeneration of Shorea robusta is the time lag between the falling of seed and the commencement of the ________.
- Read the following statements and choose the correct answer about silvicultural system/s adopted for the management of Shorea robusta:
Statement (I): Under clear felling system, a rotation age is fixed and the entire area clear felled and the crop is of uniform age.
Statement (II): Selection system is adopted for areas which are badly eroded and where regeneration is problem and regeneration is obtained by natural means, which may be supplemented by planting.
Statement (III): In coppice with standards system, a few standards are retained and the other trees above the exploitable diameter are clear felled and regeneration is obtained by means of coppice.
