The soil is improved by using semi-carbonized biomass.

An international team of researchers led by Daii Tse-hsi, Center for Environmental Resources Research, Japan Institute of Science and Technology, has developed a comprehensive soil assessment method for soil improvement using semi-carbonized biomass, which can be improved through a comprehensive analysis of the physical, chemical and biological characteristics of the soil.
soil is composed of sand and stone of different sizes, humus residues after microbial decomposition, and minerals brought in by rainwater, rivers, etc.
these substances are interwoven to form a granulation structure that keeps the soil moderately hydrate and provides oxygen to plants and soil organisms through air passages.
, the academic community has published many studies on the soil environmental cycle, but the angle is mostly relatively single.
soil characteristics have a significant impact on plant growth because plants absorb nutrients, moisture and breathe through the roots.
to maintain normal plant growth, the soil must have sufficient humidity and air.
such as in sub-Saharan Africa, the soil is very dry and the soil becomes extremely hard after water content, making farming difficult.
study, published in the British journal Scientific Reports, said they used magnetic resonance (NMR) to build structural analysis methods to improve soil structure.
they first crushed the leaves of the eucalyptus tree and heated them to 240 degrees Celsius at low temperatures in an oxygen-free environment to make semi-carbonized biomass.
then analyzed by infrared spectroscopy, thermal analysis, particle size distribution and two-dimensional solution MRI, and confirmed the moisture and hexaculoseline components of biomass formed by thermal decomposition from the metabolic group analysis.
On the basis of the above analysis, the research team mixed the semi-carbonized eucalyptus trees in various proportions in the barren soil, and found that the improved soil formed a granulation structure, which showed the physical characteristics of structural stability, and proved that the soil water preservation ability improved.
addition, plant and microbial symbrotic phenomena have emerged after soil improvement.
researchers say the method could improve soil in the expanding deserts to make them arable land, giving new hope for food solutions in an explosively growing African region.
