An eco-friendly netting for soil erosion control includes a netting body portion forming a pattern of netting apertures, the netting body portion being formed from a material that is at least partially biodegradable. The eco-friendly netting is provided as part of an erosion control blanket, where the erosion control blanket further comprises a layer of another material that is attached to the eco-friendly netting. A soil erosion control method includes providing the erosion control blanket with the eco-friendly netting.

Provided is a method for growing a plant using a water-absorbent resin that is less prone to be deactivated by calcium ions, magnesium ions, or the like in soil, water, or a fertilizer. The method includes mixing a first water-absorbent resin containing a crosslinked polyvinyl alcohol and a crosslinked phosphorylated starch or a second water-absorbent resin composed of a crosslinked phosphorylated polyvinyl alcohol into soil to form improved soil, and growing a plant such as turf on the improved soil. The water-absorbent resin is mixed in a granular shape into the soil to afford improved soil. The first water-absorbent resin includes those in which polyvinyl alcohol itself, a phosphorylated starch itself, and polyvinyl alcohol and a phosphorylated starch are crosslinked intermolecularly. The second water-absorbent resin includes one in which a phosphorylated polyvinyl alcohol itself is crosslinked intermolecularly.

A method of dispersing seeds of a plant via a digestive system of an animal includes steps of feeding the seeds to the animal, positioning the animal in a pasture, and dispersing, via defecation by the animal, the seeds onto the pasture, whereby the seeds are mixed with manure produced by the animal. The seeds may be for a forage crop, such as one used for forage for the animal which disperses the seeds. The method may be used to overseed areas which have already planted forage crop in order to preserve or improve the health of the population of forage crops in the pasture.

Provided is a micro-polluted water body ecological treatment method based on aquatic forest system construction. The method comprises the following steps: (1) investigating a pollution source of a micro-polluted water body; (2) estimating an annual pollution load of the micro-polluted water body which needs to be reduced; (3) designing aquatic animals and plants; and (4) constructing the aquatic animals and plants. By using a water body treated by means of the method in the present invention, an aquatic forest can be formed, and the synergistic effect, nutritional relationship, food chain relationship, etc., between organisms can be fully utilized for effective operation, such that not only can the combined benefits of water quality purification and water body resource utilization be achieved, but the organic unity of environmental protection, economic development, and the improvement of people's livelihood can also be realized.
