Abstract
Compositions including a biochar, and related methods are described herein. The composition can be produced by contacting a biomass with a pretreatment agent including an alkali metal or an alkaline earth metal to form a pretreated biomass, and pyrolyzing the pretreated biomass under conditions sufficient to form a biochar. A related method includes contacting soil with the composition thereby increasing a soluble plant available silicon content in the soil.
Claims17
A method comprising:
- contacting a biomass with a pretreatment agent comprising an alkali metal or an alkaline earth metal to form a pretreated biomass;
- and
- pyrolyzing the pretreated biomass under conditions sufficient to form a biochar.
A composition comprising a biochar having at least the following characteristics:
- a pH in the range of about 8 to about 11, based on 1:100 biochar to deionized water ratio;
- a total potassium content in the range of about 13.31 g/kg to about 378.33 g/kg, as measured by inductively coupled emission spectrometry;
- and
- a soluble plant available silicon content in the range of about 0.75 wt. % to about 6.0 wt. % or greater, based on total weight of the composition containing biochar, wherein the soluble plant available silicon content is determined by 5-day Na2CO3—NH4NO3 extraction.
A composition comprising a biochar having at least the following characteristics:
- a pH in the range of about 9.5 to about 10.5, based on 1:100 biochar to deionized water ratio;
- a total potassium content in the range of about 79.77 g/kg to about 183.78 g/kg, as measured by inductively coupled emission spectrometry;
- and
- a soluble plant available silicon content in the range of about 0.75% to about 6.0 wt. % or greater, based on total weight of the composition containing biochar, wherein the soluble plant available silicon content is determined by 5-day Na2CO3—NH4NO3 extraction.
