Difference between Saline Soil and Silty Soil

Saline soil is rich in salt content while silty soil is rich in nutrient content. Saline soil has a grainy and gritty feel while silty soil has a soapy, smooth feel. The particle diameter of saline soil is more than that of silty soil. Saline soil is found in arid areas while silty soil is found in delta regions.

What is difference between saline soil and alkaline soil?

Saline soils contain an excess of neutral soluble salts of chlorides and sulphates whereas sodic or alkali soils contain sodium carbonates/ sodium bicarbonates. They lack in nitrogen and calcium and have low water bearing capacity.

What type of land is saline?

Primary salinity occurs naturally in soils and waters. Examples of naturally occurring saline areas include salt lakes, salt pans, salt marshes and salt flats. Secondary salinity is salting that results from human activities, usually land development and agriculture.

What is meant by saline soil?

By definition a saline soil is a nonsodic soil containing sufficient soluble salt to adversely affect the growth of most crop plants with a lower limit of electrical conductivity of the saturated extract (EC_e) being 4 deciSiemens / meter (dS/m), which is equivalent to a value of 4 mmhos/cm.

Why saline soil is a problem soil?

The problem of soil salinization is a scourge for agricultural productivity worldwide. Crops grown on saline soils suffer on an account of high osmotic stress, nutritional disorders and toxicities, poor soil physical conditions and reduced crop productivity.

Does salt make soil acidic?

Salts generally found in saline soils include NaCl (table salt), CaCl2, gypsum (CaSO4), magnesium sulfate, potassium chloride and sodium sulfate. ... The normal desired range is 6.0 to 7.0, but many Texas soils are naturally 7.5 to 8.3. Leaching the salts from these soils does not increase the pH of saline soils.

Is acidic or alkaline soil better?

A soil with a pH number below 7 is acid, while one with a pH above 7 is alkaline. Garden plants typically grow best in neutral or slightly acid soil (pH 7 or slightly below; see illustration at left). ... In general, some nutrients cannot be efficiently absorbed by plant roots if soil pH is too high.

How do you treat saline soil?

River water or groundwater used in irrigation contains salts, which remain behind in the soil after the water has evaporated. The primary method of controlling soil salinity is to permit 10-20% of the irrigation water to leach the soil, that will be drained and discharged through an appropriate drainage system.

How is saline water treated?

Reverse osmosis is an effective means to desalinate saline water, but it is more expensive than other methods. As prices come down in the future the use of reverse osmosis plants to desalinate large amounts of saline water should become more common.

What increases soil salinity?

Soil salinity is the salt content in the soil; the process of increasing the salt content is known as salinization. ... Salination can be caused by natural processes such as mineral weathering or by the gradual withdrawal of an ocean. It can also come about through artificial processes such as irrigation and road salt.

What are the characteristics of saline soil?

Saline Soils are those soils that contain sufficient salinity to give ECe Values greater than 4 dS/m, but have an ESP less than 15 (or an SAR less than 13) in the saturation extract. Thus, exchange complex of saline soils is dominated by calcium and magnesium, not sodium. The pH of saline soils is usually below 8.5.

Where can you find saline soil?

SALT-AFFECTED SOILS, RECLAMATION

Saline and sodic soils exist in arid and semiarid regions and in regions of poor natural drainage. These soils have poor physical properties owing to high sodicity and high pH.

How saline soil is formed?

Saline soils are formed whenever climate, soil and hydrological conditions favour accumulation of soluble salts in the root zone. Arid and semi-arid regions of low rain fall and high temperature leads to less leaching, more evaporation of water and less transport of soluble salts.
