The critical moisture threshold below which cohesive soils cease sticking to metallic tillage implements is known as______________________?
Show answer Hide answer
Answer: C. Sticky limit
Explanation
The sticky limit defines the specific moisture content where cohesive soil stops adhering to metal tools. Operating tillage implements below this moisture threshold prevents soil from sticking to moldboard surfaces. Agricultural engineers utilize this critical Atterberg limit to optimize tractor pull efficiency during plowing. Soil consistency describes the manifestation of cohesive and adhesive forces acting within soil masses. Tillage operations require careful soil moisture management to avoid excessive smearing and compaction. Atterberg limits provide standardized boundaries for evaluating the engineering properties of fine soils.
Farmers monitor soil stickiness to determine the exact timing for safe mechanical field cultivation. Improper tillage of wet cohesive soils damages soil structure and increases machinery fuel consumption. Agricultural machinery design incorporates soil mechanics principles to minimize implement draft requirements. Liquid limit marks the transition moisture content where soil begins to behave like a viscous fluid. Plastic limit denotes the boundary moisture where soil can be rolled into thin threads without crumbling. Alter berg limit missparks the historical name of Atterberg limits used in geotechnical soil science.
