Polysaccharides produced by soil microbes and similar synthetic polymers applied to soils are largely responsible for the crusts that form when rain follows tillage.

Question

Quizplus · Accepted Answer

Polysaccharides produced by soil microbes and similar synthetic polymers actually help in soil aggregation and stability, reducing the likelihood of crust formation. Soil crusts are more commonly formed due to the impact of raindrops on bare soil, dispersing fine particles which then settle and compact upon drying, not directly due to polysaccharides or synthetic polymers.
