A hemp-based composition can facilitate soil-free cultivation

Welcome to Pocket Science – Recent research from Husker scientists and engineers. For those who want to quickly learn Husker’s research “what”, “what so” and “what now”.

What?

Given the diversity of its applications, hemp has become an increasingly popular crop in the United States and elsewhere over the past half decade. That has led to an increase in the number of attractive products – hemp fiber.

Combining hemp fiber with other materials can create land, water, and pesticide use, among other benefits, to create multi-functional biocoptors suitable for hydroponics, soilless fruits and vegetables.

However, hemp-based biokopops can sometimes lose the mechanical strength needed to support proper plant growth. And modern chemical methods to improve the structural reliability of those biocoptors often produce volatile organic compounds, or VOSs, are harmful to health and the environment.

so what?

Nebraska chemist Barry Chung and his colleagues recently introduced a chemical compound called hemp fiber, lingin. Unlike previous techniques, the group’s approach is to use water as a solvent, instead of producing harmless organic salts. VOSW as products.

Mechanical testing The new biocompatibility is more durable than a standard hemp-based counterpart, and it retains its shape better when subjected to compression forces. It can also contain approximately twice as much water as pure hemp fiber.

The group continues to grow both deacon radish and green peas from the biocompatibility, a promising sign that it is a potential, environmentally friendly growth medium.

What now?

Applying other lignin-containing fiber chemical techniques, including flax, jute and coconut shells, could produce sustainable biokopops for use in growth media, bioplastics and packaging materials, the researchers said.

The expansion of the hydroponic growth media may be particularly important as the world’s population grows, water resources and soil erosion make farming more difficult.
