ประชุมวิชาการกรมพัฒนาที่ดิน ปี 2560 “วิชาการงานพัฒนาที่ดิน ขับเคลื่อนคุณภาพชีวิตเกษตรกรสู่ความยั่งยืน” วันที่ 19 - 21 กรกฎาคม 2560

The findings revealed that, 1) The occurrence and dispersion of saline soil were
happened by inappropriate methods in rock salt production both boiling and dried methods,

unsuited land preparation for cropping, deforestation of recharge and discharge area, a huge

of salt dome located underground, unsmooth surface of land ,unsuitable land preparation
for cropping, drought and water shortage condition, water reservoir and distribution

constructed over the salt affected area without saline soil dispersion prevention. 2) Saline
soil management: The opportunities on saline soil occurrence and dispersion were awarded

by observation the amount of salt scattered on the surface in the dry season and low level

of soil fertility included health and yield of crops grown. Hence, the amount of salt existing
on the surface of salt-affected soil act as the indicator for classification of salt-affected

degree. The management on the salt-affected degree deducting and dispersion prevention in

the farmland by (1) enlarging size of piece of land, surface farmland leveling and big berm
(khanna) constructing by family labor and cattle (2) putting organic matter, green manure

crop, livestock manure and farm wastes, rice stubble and straw plowing and then mixed with

the soil at the rice root zone (3) big dyke creating surrounding the highest salt-affected area
and fast growing tree planting (4) ditch draining providing in the paddy land (5) cattle and

drug raising in farmland (6) soil moisture preservation (7) conservation, rehabilitation, and
cultivating the native and salt-tolerant local variety of vegetable crops and fruit trees for

home consumption and family income ( 8) un-saline underground water providing for
cropping (9) dyke construction for preventing saline water flow through the free-salt affected

land. 3) saline soil utilizing included: (1) for the low to high level of salt-affected soil were

utilized for growing the local rice varieties and on land and aqua vegetables in the wet
season including for higher quality livestock raising (cattle, poultry), catching and raising salt-

tolerant aqua-animals, amphibian animals and edible insects (2) The highest level of salt-

affected soil were utilized: (2.1) for agricultural production such as acting as a good food
sources (local varieties of vegetable crops, fruits, edible insects) salt-tolerant tree growing for

high quality fire- woodlot production, edible insect resident, source of lumber, economic

fruit trees growing, cattle and duck raising field. (2.2) for non-agriculture production such as
green rock soil production both boil or melting and dry salt, wisdom on spa-salt house,

mineral drinking water providing, rock salt production study tour.
A risen recommendations were as follows; (1) the reviewing, improving, modifying and

extending the effective indigenous innovation , technology and body of the knowledge on

salt affected land management by integrating with the advance innovation, technology and
