Then, a top layer of organic mulch is applied. More elaborate sheet mulching involves more layers. Sheet mulching is used to transform a variety of surfaces into a fertile soil that can be planted. Sheet mulching can be applied to a lawn, a dirt lot full of perennial weeds, an area with poor soil, or even pavement or a rooftop. [3]

[11] However, mulch can also prevent water from reaching the soil by absorbing or blocking water from light rains and overly thick layers of mulch can reduce oxygen in the soil. [12]
In 2012 a team of researchers led by Stephen Sillett did a detailed mapping of the branches of the President tree and calculated the volume of the branches to be 9,000 cubic feet (250 m 3). This would raise the total volume for the President from 45,000 cubic feet to 54,000 cubic feet (1,500m 3) surpassing the volume of the General Grant Tree.

Living mulches grow for a long time with the main crops, whereas cover crops are ...
Smaller quantities of barkdust, typically 2 to 3 cubic feet (0.057 to 0.085 m 3) are sold prepackaged in home improvement and gardening retailers. [citation needed] For landscaping applications, a layer of 2 to 3 inches (5.1 to 7.6 cm) is generally recommended. For use in playgrounds, a 12-inch (30 cm) layer is often recommended.
