Biomass charcoal has shown huge application potential at everyways such as raising crop yield, enhancing soil nutrient, increase soil fertility, soil structure improved addictive reparation, contaminated environment reparation and reductions of greenhouse gas discharge, causes extensive concern as a class novel environmental functional materials at society.
Charcoal has huge surface-area and various small structure, this pore space structure more easily assembles absorption nutrition nutrient thing, promotes beneficial microorganism growth, thus makes soil become more fertile, be conducive to the growth of plant, realize the green agriculture of Sustainable development.So, biomass charcoal can not only reduce greenhouse gases, as the effect of methane, Nitrous Oxide and Carbon emission, and to improving soil health, reduce nutrient loss, recover soil fertility, improve the utilising efficiency of fertilizer, improve soil productivity there is active effect.
Containing abundant space and organic macromolecule structure in biomass charcoal, when with fertilizer join execute, in soil, more easily form macro aggregate, promote absorption and the maintenance of the nutrient ion of soil, the NH in soil
4 +absorption and fixing effect are able to obvious enhancing, improve the utilization ratio of crop to nitrogen, thus nitrogen loss is reduced.In addition, there is certain hour rear face portion branch and formed carbonyl, phenolic group etc. by mild oxidation in biomass charcoal in soil, and this contributes to the cation exchange capacity increasing soil.Biomass charcoal is to NH
4 +and N0
3 -there is stronger characterization of adsorption, thus the nitrogen stayed in soil can be held, the volatilization of effective reduction agricultural land soil ammonia and the pouring drop of control Soil Nitrogen nutrient run off, these characteristics enable biomass charcoal effectively reduce the loss of agricultural land soil nitrogen nutrient, improve crop yield, decrease the pollution of area source that applying quantity of chemical fertilizer and farmland nitrogen nutrient loss cause simultaneously.
Biomass charcoal contains various abundant ash element, as soluble nutrient utilization absorbed by crops in soil, thus can improve soil organic matter content and soil carbon maintenance capacity, and biomass charcoal itself also can improve upper earth fertility as fertilizer.What biomass charcoal contained enriches ash element such as K, Ca, Mg etc. is all soluble state, the soluble base ion in solution is become after entering soil, improve the degree of base saturation of soil, reduce its Exchange alkalinity and exchangeable aluminum content, be conducive to improving other cation exchange capacity, and reduce aluminum ion activation, reduce the saturation ratio of aluminium in acid soil, thus improve the pH value of soil.Aluminium in Soil ion too much can produce detrimentally affect to plant-growth and soil microbial activity.
