Indian StandardGUIDE FOR

EVALUATION OF SOIL )lROPERTIESRELEVANT TO IRRIGATION

o. FOREWORD

0.1 This Indian Standard was adopted by the Indian Stannard.Institution on 25 October 1982, after the draft finalized by the WaterRequirements for Crops Sectional Committee had been approved by theAgricultural and Food Products Division Council.

0.2 Irrigation water plays a vital role in many soil process. The mannerin which water is distributed within the soil mass depends to a considerable extent on the individual soil properties.

0.3 In rating land for irrigation ( agriculture ), first attention should begiven to physical condition which make the land adoptable to carefulcontrol of moisture. Freedom from undesirable chemical characteristicsreceives second consideration and third, the soil properties which effectthe inherent productivity are to be considered.

O.f It is hoped that this guide would help in deciding the method ofirrigation, suitable crops for the area in relation to efficient utilization ofwater. This would also be useful to planners in selecting site forirrigation projects.

0.5 For the purpose of deciding whether a particular requirement of thisstandard is complied with, the final value, observed or calculated, expres­ling the result of a telt or analysis, shall be rounded off in accordancewith IS : 2-1960·, The number of significant places retained in therounded off value should be the same as that of the specified value in thisItandard.

1. SCOPE

1.1 This standard gives guidelines for evaluation of soil properties inrelation to irrigation.

2. PHYSICAL PROPERTIES

2.1 Testare

2.1.1 Texture is an expression to indicate the coarseness or fineness ofthe soil as determined by the relative proportion of the various sizedprimary particles in the soil mass. It is one of the fundamental andpermanent characteristics that has direct bearing on structure, porosityadhesion and consistency. Sandy soils of open characters possess gooddrainage and aeration and are usually loose and friable and easy tohandle in tillage operation. Clayey and silty soils owing to have largesurface area possess high absorbtive and retention capacity for moisture.They usually have fine pores, are moderate to poor in drainage andaeration and are relatively difficult to handle for cultivation purpose.Proforma for land irrigability classes has also been mentioned inAppendix A.

2.1.2 The standards followed for soil Irrigability classes are mentionedbelow:

SoilI,rigability Class

ABCDNon-irrigable class

2.1.3 Basis for above classification of soil texture are given in Table 1.

2.2 Etrectlve Soil Depth

2.2.1 Soil depth modifies to a great extent the rooting system of plantswhich is ultimately reflected in irrigation, crop growth and yield.

2.2.2 The standards followed for effective soil depth in soil irrigabilityclassification are as under:

2.3 IDfiltratloD

2.3.1 Infiltration is the downward entry of water into the soil. It isthe maximum rate at which a soil in a given condition at given time eanabsorb rain or irrigation water. It is classified as below:

Class Buic Infilteratioll Raumm/Hour

1. Very ,10\\' Less than 0'25 em/hour to 2'52. Slow 2'5 to 12'53. Moderate 12·5 to 254. Rapid More than 25

2.3.2 Infiltration is a dynamic and quite variable character of soil andcan be fairly well controlled by management practices.

2.4 Permeability

2.4.1 Permeability are of two types (i) Qualitative (ii) Quantitative.

2.4.1.1 Qualitative - The quality or state of porous medium relativeto the readyness with which such a medium conducts or transmit fluids.

2.4.1.2 OJlantitative - The specific properties governing the rate orreadyness with which a porous medium transmits fluid under standardposition.

2.4.2 The permeability depends upon pore size distribution of the soil.Texture and structure of a soil often studied in field for qualitativeassessment of permeability. Concentration and composition of saltsdissolved in irrigation water also effect the permeability of soils.

2.4.3 The degree of permeability may be distinguished as follows:

Permeability Class mmlhour

'I. Very slow Less than 1·22. Slow 1·3 to 53. Moderately slow 5 to 204. Moderate 20 to 505. Moderately rapid 50 to 1306. Rapid 130 to 2507. Very rapid Above 250

2.4.4 The standards followed for permeability for soil irrigability classare as under:

Permeabilib' mm/hour

5 to 501·3 to 550 to 1300·3 to 1·3130 to 250Less than 0·3 and

greater than 250

Soil permeability as a criteria is not applicable to deep black soilbecause of their unique properties. Deep black soils ( vertisols) whichare inherently slowly permeable due to expanding 2: 1 lattic type mineralsdo not qualify for irrigability class-A, they would qualify for B, C 8t DClass.

IS : 10317 • 1982

2.5 Drainage

2.5.1 The processes of discharge of water from an area of soil by sheetor stream; flow ( surface drain ige ) and removal of excess water fromwithin soil by downward flow through the soil ( internal drainage).Generally speaking coarse texture soil drain better than fine texture soil.Drainage depends directly on permeability of soil.

2.5.2 Standards followed for drainage for irrigahility class arc a~ below:

1\ an 1 B Class I 40VVer subsoil is at least moderately permeable01' permeable layer of at lea-t fi inch thicknessoccurs immediately below soil but within 10feet ( sand and gravels ).

(~ and D Class Moderately permeable subsoil or other perme-ahle layer of at least 6 inch thickness occurswith depth of 10 metres.

2.6 Soil TelDperature

2.6.1 Soil temperature has extensive effect on soil properties andbehaviour. The water holding capacity of soil decreases slightly withrise in temperature. Soil moisture is the most vital controlling factor insoil temperature.

3. CRITERIA FOR CLASSIFICATION

3.1 Criteria for classification of soil on the basis of properties ( see 2 ) aregiven in "fable 2.
