Question

Explain why adding organic matter to backfill contributes to a transplanted tree being potentially subjected to more drainage problems in a wet year than a tree planted in backfill that had not had any organic matter added to it. Why is the transplant wetter when wet?

Answer 1

answer) Adding organic matter to backfill do not leads to larger root system or penetration of root into native soil. the soil within backfill that have organic matter differs from structure and texture compare to native surrounding soil. this encourage the roots growth within the backfill and discourage its roots ground in native soil. The water movement between the surrounding native soil and the soil in the backfill is disrupted and the planting hole can act like a sponge, holding excess moisture after rain or irrigation. Thus it is more wetter having backfill with organic matter.
