Abstract
Described herein are compositions and methods relating to functionalized sands or soils.
Claims16
A modified composition of sand or soil that acts as mulch, comprising:
- one or more particles of sand or soil, wherein the one or more particles have a size which is 600 μm or less;
- and
- a hydrophobic layer coating each of the one or more particles of sand or soil,
- wherein the hydrophobic layer includes a hydrophobic substance, and a ratio of (1) an entirety of the hydrophobic substance making up the hydrophobic layer and (2) the one or more particles of sand or soil is between 1:300 to 1:1000 by weight so that water does not penetrate through the modified composition of sand or soil after one week.

A method of reducing irrigation requirements for an agricultural system, comprising:
- providing a mulch that includes one or more particles of sand or modified soil, wherein the one or more particles have a size which is 600 μm or less, and each of the one or more particles is coated with a hydrophobic layer having a hydrophobic substance, and a ratio of (1) an entirety of the hydrophobic substance making up the hydrophobic layer and (2) the one or more particles of sand or soil is between 1:300 to 1:1000 by weight so that water does not penetrate through the modified composition of sand or soil after one week;
- and
- distributing the mulch on one or more apexes of a soil for preventing water evaporation from the soil.
A modified composition of sand or soil that acts as mulch, comprising:
- one or more particles of sand or soil, wherein the one or more particles have a size which is 600 pm or less;
- and
- a hydrophobic layer individually coating each of the one or more particles of sand or soil,
- wherein the hydrophobic layer around each of the one or more particles of sand or soil includes a hydrophobic substance, and a ratio of (1) an entirety of the hydrophobic substance making up the hydrophobic layer and (2) the one or more particles of sand or soil is between 1:300 to 1:1000 by weight so that water does not penetrate through the modified composition of sand or soil after one week.
