A system and method are provided for promoting vegetation growth on a steeply sloping surface. The system of the present invention includes anchors that are secured to the sloping surface, an inner mesh layer in contact with the slope, a geosynthetic layer placed over the inner mesh layer, and seeded compost material placed in the gap or space between the geosynthetic layer and the inner mesh layer. An outer mesh layer is placed over the geosynthetic layer to help stabilize the geosynthetic layer. The geosynthetic layer and outer mesh layer are also secured to the protruding anchors. Vegetation grows in the compost material and roots of the vegetation penetrate the inner mesh layer into the slope. An established root system stabilizes the slope. The seeded compost material provides an environment that greatly enhances the growth of vegetation on steeply sloping surface which otherwise do not have adequate soil to promote growth. The anchors provide additional structural stabilization for the slope and also provide a means to attach the layers of materials.

The invention belongs to the field of environmental microorganisms, and particularly relates to a production method of efficient phosphorus-dissolving epicoccum sorghinum with the characteristic of resisting heavy metals. Through classification, the epicoccum sorghinum is identified. The production method includes the steps that copper tailing soil and sterile water are cultured in a mixed mode, and a heavy metal sterile mixed solution with the concentration suitable for the growth of thalluses is screened; repeated culture is conducted for six times; fourth-time culture liquid, fifth-time culture liquid and sixth-time culture liquid are sucked and added into culture mediums containing organic phosphorus and inorganic phosphorus for plate spread culture, culture dishes with a large numberof bacterial colonies are selected, plate streaking culture is conducted in the culture mediums containing the organic phosphorus and the inorganic phosphorus, and the bacterial colonies with obviousphosphorus-dissolving rings are screened; and culture purification results are subjected to shake cultivation, and finally screening purification is conducted to obtain phosphorus-dissolving bacterialstrains resisting the heavy metals. Efficient phosphorus-dissolving funguses resisting the heavy metals are screened from contaminated land, the soil phosphorus supply and demand contradiction can beadjusted, reclamation land soil in a mining area is improved, vegetation growth is promoted, the utilization ratio of heavy metal contaminated plowland soil phosphorus by crops is increased, and useof fertilizer is reduced.

A system for allocating irrigation resources includes a hub for collecting imaging data and soil condition readings from watering areas proximal to sprinkler nodes.

There is a biological composition and method of use. Included is a microorganism quantity, and a nutrient quantity which may have a supplement, a short-term nutrient and a long term nutrient. The composition may be applied to a container having water wherein the microorganisms rapidly reproduce. As the microorganisms reproduce they may be extracted. Once extracted, they may be introduced into a cleaning system and dispersed to surfaces of an animal production facility. There, the microorganisms may process animal waste and the slime associated thereto. Further, the microorganisms may flow into a lagoon to beneficially participate in waste processing. Still further, the microorganisms may enhance the ability of the lagoon to prepare the waste for distribution to plants.
