[2] Cultivation influences the infiltration rate by increasing the porosity of  the surface soil and breaking up the surface seals
[3] Additions of organic matter increase infiltration rate substantially.
[4] Infiltration rates are generally lower in soils of heavy texture than on  soils of light texture
[5] All are correct

[Answer] All are correct

[Explanation]

All statement are correct and must be kept in mind

Q)Length of growing period (LGP) for arid eco system is?(Agriculture MCQ)

[2] Capillary water
[3] Gravitational water
[4] Soil water
[5] None of the above

[Answer] Capillary water
