      Soil Health Tesing       There   are   many   factors   that   contribute   to   overall   Soil   Health   that   include   a   combination   of   chemical,   physical,   and biological   activity   that   perform   a   wide   range   of   functions   that   influence   plant   growth.   Two   key   indicators   that measure   soil   health   and   its   influence   on   plant   growth   are   overall   total   and   quality   of   biological   activity   and   nitrogen mineralization. A&L   Biologicals   will   be   offering   a   new   test   which   will   tell   you   more   about   the   biological   components   of   your   soil. This test   will   give   you   three   pieces   of   information   that   equate   to   soil   health:   1)   Biological   Quality,   2)   Biological Activity   and 3) Mineralisable nitrogen The   technology   of   this   test   is   to   measure   carbon-dioxide   (CO2)   respiration   which   is   associated   with   beneficial   soil and   compost   microorganisms.   In   soil,   CO2   respiration   reflects   the   quantity   and   quality   of   organic   humus   which   is essential   to   sustainable   fertility.   In   compost,   it   reflects   the   age   and   safety   of   the   material.   The   higher   the   level   of biological   activity   of   soil   humus,   the   healthier   a   soil   is   and   the   more   nutrients   -   like   nitrogen   and   phosphorus   -   it   will provide   naturally   for   growing   plants.   In   addition,   a   microbial   rich   humus   in   soil   and   compost   is   a   key   to   excellent   soil- tilth   and   promotes   natural   resistance   to   soil-borne   plant   diseases.   Combining   this   information   with   other   indicators   of soil   health   such   as   organic   matter   we   can   begin   to   get   an   clear   indication   of   how   healthy   a   soil   is   and   its   ability   to release nitrogen. USDA / NRCS Approved Microbial Count and Soil Nitrogen Release Rate USING SOLVITA METHODOLOGY Excerpts From: Soil Biology and Crop Production and Western Australian Farming Systems "Agricultural   management   practices   ultimately   seek   to   optimise   plant   and   animal   productivity   within   the   overriding constraints   of   both   climate   and   the   capacity   of   the   soil   (physical,   chemical   and   biological   attributes)   to   support   plant growth   (Abbott,   Murphy   2003).   While   optimal   physical   and   chemical   conditions   of   the   soil   for   plant   growth   are   often well   defined,   we   have   a   much   poorer   understanding   of   the   control   that   biological   factors,   particularly   non-pathogenic associations,   have   on   plant   growth....   Once   these   key   attributes   have   been   identified,   management   practices   can   be selected that take into account the potential for enhanced soil biological fertility and improved yield." "Further   analysis   indicated   that   the   influence   of   the   microbial   biomass   on   yield   was   predominately   due   to   the   strong relationship (r2 = 0.77) to potentially mineralisable nitrogen." "Soil   biological   fertility   was   significantly   correlated   to   grain   production   in   WA.   The   benefit   was   predominately associated   with   the   size   of   the   microbial   biomass,   which   was   directly   related   to   their   capacity   to   decompose   soil organic   matter   and   fresh   residues   to   release   plant   available   nitrogen.   These   findings   confirm   our   view   that   WA farming   systems   are   highly   reliant   on   biological   nitrogen   supply   and   that   farming   systems   need   to   be   modified where possible to fully benefit from water availability and microbial nutrient supply." This test can be performed separately or added on to your regular soil test.  Submission Form Link/Info: View and/or print the submission form for this test package (PDF file). Or Contact Us
