The present disclosure provides a preparation method for a seedling substrate using residues from Populus forests as raw materials and an application. The preparation method for a seedling substrate includes the following steps: crushing Populus fallen leaves into Populus fallen leaf scraps; crushing Populus dead branches into Populus dead branch scraps; mixing the Populus fallen leaf scraps, the Populus dead branch scraps, chicken manures and garden soil to obtain a mixture; adding effective microorganisms (EM) bacterial powder to the mixture for fermentation; and adding perlite during the fermentation to obtain a seedling substrate. The seedling substrate provided in the present disclosure is rich in microorganisms and comprehensive in nutrients, does not require additional fertilizers in a seedling stage, and is capable of promoting the growth of forest seedlings.

Described is a hydroponic system wherein a feed formulation comprising a plant's nutritionally required mineral nutrients is applied to the foliage of the plant and the roots of the plant are in contact with an incomplete water solution that may comprise only hydrogen and oxygen. The feed formulation, methods of feeding a plant or plant seed, and plants produced thereby are also described.

A system for breaking down debris in a plant-supporting medium. The system includes a masticator device for breaking down the debris by a plurality of brushes. The system further includes a tumbler device fluidly coupled to the masticator device, configured to rotate and spray water to clean the plant-supporting medium and remove the debris.

A grow field configured to support plant or crop cultivation, the grow field having a first end, a second end, a bottom surface and a boundary wall, a first reservoir proximate to the first end of the grow field, wherein the first reservoir is configured to produce a waste nutrient stream, a second reservoir proximate to the second end of the grow field, wherein the second reservoir is configured to act as a settling tank for the produced waste nutrient stream; an Artificial Intelligence (AI) unit in connection with the grow field, reservoirs for providing a feedback for improving a growth rate of the cultivated plants or crops; and a controller in communication with the AI unit for receiving and processing output signals from at least one sensor and sending an assessment of a plurality of monitored parameters to the AI unit, based on the processed output signals.

Described herein are a protective plant barrier and soil enhancer, and methods for making same, that surrounds and protects seeds, seedlings, and growing/grown plants from insect pests while also providing enhancements to the soil to improve plant growth.

The present application relates to a system for retaining water and providing nutrients to plantlets, comprising: (a) a first surface that is concaved, an opening, and an exterior wall extending between the first surface and the opening; (b) an interior cavity defined by an interior surface of the exterior wall, a second surface, and an opening that is opposite the second surface; and (c) a channel extending through the first surface and the second surface, the channel comprising a first end and a second end, the channel in fluid communication with the interior cavity, the first end being distal to the interior cavity and the second end being proximal to the interior cavity. The system can be constructed of a first organic material, a binding material and a buffering material. In some instances, the system further comprises one or more modules spatially disposed within the interior cavity.
