What are the disadvantage of sloping agricultural land technology?
The greatest problem man will encounter when forest trees are extensively cut without replanting, combined with improper farming of fragile, sloping lands is soil erosion. The erosion of topsoil–the thin upper crust on the earth’s surface in which man plants his food crops–is an extremely serious problem in Asia.
How Sloping Agricultural Land Technology salt improves the field of agriculture especially in upland areas?
As a proven system of upland farming, SALT has certain good qualities over both the traditional techniques of slash-andburn and conventional terrace farming. The SALT system protects the soil from erosion. SALT helps restore soil fertility and structure. SALT is efficient in food crop production.
Who developed the sloping agricultural land technology?
The Mindanao Baptist Rural Life Center
The Mindanao Baptist Rural Life Center (MBRLC), a non-government organization based in the southern part, has developed and spread an agroforestry scheme called Sloping Agricultural Land Technology (SALT) to help control soil erosion and increase crop yields.
What is the effect of farming on slopes?
Inhibitory effects of crops on slope runoff rate and sediment yield were enhanced with crop growth and decreased with increasing slope gradient. Crop growth and coverage could offset the impact of increasing slope gradient on runoff and sediment to some extent and reduced water and soil loss on slopes.
How do I farm my hilly land without losing my soil?
Drive tractors as little as possible. Use drip irrigation that puts small amounts of water in the ground frequently. Avoid watering crops with sprinklers that make big water drops on the ground. Keep fields as flat as possible to avoid soil eroding down hill.
Which salt is suitable for agriculture?
Sodium is a nutrient for a number of crops, particularly those with ‘maritime’ origins as their ancestors grew near the sea. The most high profile of these crops is sugar beet. Sodium is also recommended for use on crops such as asparagus, celery and carrots.
What is simple Agro Livestock Technology?
There are two more types of the system: Simple Agro-Livestock Technology (SALT 2) and Small Agrofruit Livelihood Technology (SALT). The practice involves planting hedgerows of trees and shrubs such as mangium, narra and acacia. Prunings from the trees are applied to crops as mulch and a source of fertilizer.
How can we conserve soil away from erosion by system called salt?
Basically, the SALT method involves plant- ing field crops and perennial crops in bands 3-5 m wide between double rows of nitrogen-fixing shrubs Page 3 and trees planted along the contour. These minimize soil erosion and maintain the fertility of the soil.
Which is the most effective agent of erosion?
Water
Water is the most efficient and effective agent for erosion. Erosion by water commonly occurs in two different geologic settings: 1. Coastlines – erosion that occurs on coastlines is due to the action of ocean currents, waves, and tides.
What are the problems of Ploughing on a sloping land?
The main problem comes with the increased difficulty in detaining or slowing down run-off to non-erosive rates as slopes increase. But, at the same time, another factor frequently comes into play. Usually, as slopes increase, the soils become shallower and their ca- pacity to hold water decreases.
What do farmers do to prevent soil erosion?
1. Planting Vegetation as ground cover: Farmers plant trees and grass to cover and bind the soil. Plants prevent wind and water erosion by covering the soil and binding the soil with their roots. The best choice of plants to prevent soil erosion are herbs, wild flowers and small trees.
What does no-till farming do?
No-till farmers grow crops with minimal disturbance to their fields and the organisms that call them home. This builds healthier soils while reducing money spent on fuel and labor – a win-win. With harvest season winding down, you’re no doubt making an important decision for your working land.
What kind of Technology is sloping agricultural land technology?
This technology is known as SALT or ”Sloping Agricultural Land Technology.” Introduction to SALT SALT is a package technology of soil conservation and food production, integrating differing soil conservation measures in just one setting.
What are the problems of sloping agricultural land?
Common Problems in sloping agriculture land 1. Degradation of land 2. Top soil erosion leading to nutrient losses. 3. Declining crop yield 4. Increasing food insecurity 3. SALT • There are several traditional ways of controlling soil erosion, such as reforestation, terracing, multiple cropping, contouring and cover cropping.
What are the advantages and disadvantages of building on sloped land?
Now that we have looked at the advantages, here are two (2) disadvantages of building on sloped land: 1) With sloped lands, time and expense is incurred in getting the land suitable for building. That usually involves excavation fees and constructing additional supports for the structure.
What are the disadvantages of Technology in agriculture?
The excessive use of chemicals by the help of machines reduces the fertility of the land. Lack of practical knowledge the farmers cant handle the machines properly. While the cost of maintenance is very high. Overuse of machines may lead to environmental damage. It is efficient but has many side effects and drawbacks.
