This research project will investigate how the addition of biochars, derived from maize silage and PGPR can improve the soil biological, chemical, physical properties, plant growth and nutrient uptake on drought affected soils where water scarcity and low soil organic matter status are major factors limiting crop production. In greenhouse and field experiments we will test the hypothesis that PGPR along with biochar application is an effective strategy to reduce soil degradation by drought and to increase soil fertility by enhancing soil organic matter status, soil microbial activity and nutrient availability, apart from having other beneficial effects such as C sequestration. </span><span lang="EN-US" style="color&#58;windowtext;font-family&#58;&quot;times new roman&quot;;font-size&#58;12pt;">In addition it is expected that biochar </span><span lang="EN-US" style="color&#58;windowtext;font-family&#58;&quot;times new roman&quot;;font-size&#58;12pt;">may protect</span><span lang="EN-US" style="color&#58;windowtext;font-family&#58;&quot;times new roman&quot;;font-size&#58;12pt;"> bacteria under drought stress in soils,</span><span lang="EN-US" style="color&#58;windowtext;font-family&#58;&quot;times new roman&quot;;font-size&#58;12pt;"> increasing their survival in soil, where competition with native microorganisms for nutrients is very high.</span><span lang="EN-US" style="color&#58;windowtext;font-family&#58;&quot;times new roman&quot;;font-size&#58;12pt;"> M</span><span lang="EN-US" style="color&#58;windowtext;font-family&#58;&quot;times new roman&quot;;font-size&#58;12pt;">oreover, potential of biochar as inoculums carrier can promote its production from biological wastes, preventing these materials from emitting large amounts of carbon dioxide into the atmosphere by being burned or composted.</span><span lang="EN-US" style="color&#58;windowtext;font-family&#58;&quot;times new roman&quot;;font-size&#58;12pt;"> The project will give an opportunity to expand current research on biochar and bacterial fertilizer amendments for alfalfa of degraded and low-fertility soils in Europe to a wider range of soil types and climate conditions, from which we can expect new insights into the way biochars interact with soils and soil biota in general. Improving soil quality by biochar and PGPR can make a great impact on the sustainability of the profitable use of the affected soils, in particular under conditions of climate change.</span><span lang="EN-US" style="color&#58;windowtext;font-family&#58;&quot;times new roman&quot;;font-size&#58;12pt;"></span></p> <p>&#160;</p></div><div class="ExternalClass7D54FACF-CC9E-4CD6-99CE-6BE8AF9493E4"><ul><li>Inst. für Landschaftsbiogeochemie</li></ul></div><div class="ExternalClass9B9EACE7-9AAD-4F85-9236-24EE3955BC9B"><ul><li>Inst. of Landscape Biogeochemistry</li></ul></div><div class="ExternalClassCD987FDB-371C-4BD7-86F0-F8B9A45BDF88">Dr. Dilfuza Egamberdieva; Dilfuza Jabborova; Martina Wiemer; Dr. Stephan Wirth</div>Wirth, Stephan<div class="ExternalClassE58D4FDE-E565-4917-B3C0-7096BC48AF5C"><a title="e-mail" target="_blank" href="mailto:swirth@zalf.de">Dr. Stephan Wirth</a></div><div class="ExternalClass5D4FAC0E-B872-4612-B0DA-75CB79C84B69"><ul><li>2016 Landschaftsprozesse</li></ul></div><div class="ExternalClass0C2D5675-164A-4B79-BD26-1E7C26DD1BEC"><ul><li>2016 Landscape Functioning</li></ul></div>x259x<div class="ExternalClassC2F9E8A8-4A02-4CA1-B300-0F632CFB6391"><ul><li>ATB - Leibniz-Institut für Agrartechnik Potsdam-Bornim </li></ul></div>x497x<div class="ExternalClass5631BACE-07BC-4284-97B2-5C6D9BC44C6A"><ul><li>Sonstige Drittmittelprojekte (Land/ Bund/ Stiftungen/ Verbände/ Gesellschaften/ Industrie etc.)</li></ul></div>Rhizosphäre; Trockenstress; Kohlenstoffhaushalt; AvH - Alexander von Humboldt-Stiftung<div class="ExternalClass7FF0BC63-5AD8-4156-9381-7C17C70A3AA5"><ul><li>AvH - Alexander von Humboldt-Stiftung</li></ul></div> 33
