A preparation method for artificially simulated soil rich in humus, relating to a preparation method for simulated soil. The purpose of the method is to solve the problem that the endurance capacity for an existing organic fertilizer to rainwash is low, thereby influencing the effect of remediation on defective soil by the organic fertilizer. The method comprises: 1, preparing a soil mixture; and 2, placing the soil mixture in a high-temperature high-pressure hydrothermal reaction kettle for a hydrothermal reaction to obtain artificially simulated soil rich in humus. The preparation method is simple, raw materials are cheap and easily obtained, and therefore the method is suitable for large-scale synthesis and preparation. The prepared artificially simulated soil rich in humus is used for increasing the soil water retention capacity and the capacity of absorption of nutrients.

A soil modifier that includes: base particles that are particles of SiO.sub.2 having a particle size of 100 nm or more, and the central particle size of the base particles is 120 nm to 800 nm in a particle size distribution of the SiO.sub.2 particles. A culture soil includes soil and the base particles.

Methods for producing a bio-based material from a waste material containing gypsum via mycoremediation. Under controlled environmental conditions, the mycological conversion of waste containing gypsum diverts waste streams from landfills and creating pathways of reuse as new mycelium-based materials. Mycoremediation provides an ability to sustainably produce resilient sources of many products and allows for economically and environmentally viable alternatives to many synthetic and carbon-rich materials.

A floatable island includes at least one layer having a structure containing grains, the grains including an expanded mineral material.

The patent details a novel method and apparatus for integrating solar nitrogen fixation into container farming systems. The core innovation revolves around a copper mesh electrode powered by solar energy to fix nitrogen directly from the atmosphere into forms usable by crops, such as ammonia. The system can operate independently from traditional nitrogen fertilizers and is designed to be modular and scalable for decentralized farming operations, particularly in urban or off-grid environments. The solar-powered nitrogen fixation process is efficient, utilizing low-voltage systems that eliminate the need for complex circuitry, enabling cost-effective, sustainable crop production. The nitrogen can be applied either via gaseous foliar feeding or through irrigation water, providing a continuous nitrogen source. This technology is especially beneficial for crops with high nitrogen demands, like leafy greens and herbs, offering an environmentally friendly and economically viable alternative to conventional nitrogen fertilization methods.
