Why do some leaves decompose faster than others?

Why do some leaves decompose faster than others?

Individual species vary in their decomposition rates [9] because of differing leaf characteristics such as leaf nitrogen and lignin contents [10], carbon quality [11] and secondary chemicals [12], [13].

In what condition do fallen leaves decay the fastest?

The researchers found that the rate of decomposition, not nitrogen release, was affected by the two key variables of temperature and moisture. The slowest rates of decomposition were in cold regions, such as boreal forests and tundra, and the fastest in the warm, moist, tropical forests.

How do leaves decompose faster?

To promote decomposition, mix leaves with grass clippings or other materials high in nitrogen. If possible, shred the leaves prior to composting. The smaller the size of the material, the faster it will decompose.

Why are decaying leaves important?

The fallen leaves, decaying, make what is called “humus,” and this humus is a very important thing to have in the soil. The acids produced by the decay of the leaves also help to perform one of the miracles of nature — the changing of rocks into humming-birds and trees and squirrels and wood flowers and fresh milk.

What happens if you leave leaves on the lawn over winter?

Excessive leaf matter on your lawn going into winter is bad for several reasons. First, it will smother the grass and if not removed very soon in the spring it will inhibit growth. Second, it can promote the snow mold diseases. And finally, turf damage from critters (voles, mice) can be more extensive in the spring.

Why is leaf litter decomposition?

As Table 1 shows, litter production and its decomposition processes have a direct and indirect effect in the functioning of the forest ecosystem. Litter decomposition provides readily available nutrients to plants because it incorporates organic carbon into soil through nutrient cycling processes.
