Benefits of technology

This patented technology involves making certain types of chemical substances that are used on top layers or buried underground during construction without causing damage. These materials help prevent weeds from growing inside buildings by reducing their weight while still providing effective moisture protection against evaporation over time. They may be made into different forms like pellets with other ingredients added thereto such as manures or litter stones. By adding these compositions onto existing surfaces they create an even layered structure where plants grow better due to improved hydration properties compared to nonwoven fabrics alone.

Problems solved by technology

This patented technical describes methods for improving crop production efficiency without losing important plant growth factors like mineral elements from rainwater irrigated areas during drought conditions. These techniques involve adding certain substances called urease enzyme into mixtures containing urea/Formalin acid salt solutions at specific temperatures before being applied onto seeds. By combining these ingredients together, they create stable compositions that release beneficial components over time when exposed to moist air.
