Question

Contour hedgerow intercropping system is also called as ________.

• A. Hill agroforestry
• B. Sloppy Agricultural Land Technology
• C. Altitudinal agroforestry system
• D. Hill based homegarden

Hint:

SALT is widely promoted across hilly regions in South and Southeast Asia to prevent soil erosion and improve food security for upland farmers.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
This question focuses on the terminology used for sustainable slope farming technologies.
These systems combine soil conservation practices with agroforestry on hilly terrains.

Step 2: Detailed Explanation:
Let us define the Sloppy Agricultural Land Technology (SALT):
Sloppy Agricultural Land Technology (SALT) was developed in the Philippines during the late 1970s.
It is a simple, effective, and low-cost method of contour hedgerow intercropping designed for farming steep slopes.
In this system, double rows of nitrogen-fixing trees or shrubs are planted closely along contour lines.
These hedgerows act as physical barriers that slow down surface runoff, trap eroding soil, and encourage natural terrace formation over time.
The alleys between the hedgerows are used to grow annual and perennial agricultural crops.
The hedgerows are periodically pruned, and the clippings are applied as mulch to suppress weeds and return organic matter to the soil.

Step 3: Final Answer:
The contour hedgerow intercropping system is also known as Sloppy Agricultural Land Technology (SALT).
Thus, Option (B) is correct.
