Units of nitrogen applied were calculated to be approximately 280kg/ha. \ Although the cover crop biomass was not measured, treatment 4 seemed to return an excess amount of nitrogen to the soil post-cultivation to that applied. \ All other treatments measured lower units of nitrogen than that applied, however, this could be influenced by the rate of breakdown (Figure 6). \ The buckwheat was terminated in late February and the soil test was taken one month later in late March 2024. album_6B9CECED_64CB_B18D_41B7_874C92729A7A_0.description = • Very good labile carbon in the areas with the warm season cover crops (Japanese millet-vetch mix and buckwheat) combined with minimum till \ • Good labile carbon in the areas with cover crops and cultivation, in both the trial and control that included grower standard cereal rye \ • Poor-average labile carbon in the areas with composting and cultivation, or minimum till, without cover crops. ### Subtitle panorama_D2723861_D8AB_1DD2_41E7_6C3C37EDEE29.subtitle = Celery - 6 weeks establishment model_EBA02D15_E719_2D75_41D4_FDCBBB98D5CD.subtitle = Celery - 6 weeks establishment panorama_D2712A9A_D8AB_1D76_41E1_24910B6EE464.subtitle = Celery - 6 weeks establishment model_EA012297_E43A_2D90_41D7_FF0AFCFE33B5.subtitle = Celery - 6 weeks establishment panorama_D276948D_D8AB_1552_41CC_337231C73D00.subtitle = Celery - 6 weeks establishment model_E9C4E5FA_E425_D793_41E7_43874E5F843B.subtitle = Celery - 6 weeks establishment panorama_D272E47D_D8AB_75B2_41E0_99CC906B8937.subtitle = Celery - 6 weeks establishment model_E813F7B1_E42A_7391_41BC_2C41BC0F82C5.subtitle = Celery - 6 weeks establishment ### Title album_6B9CECED_64CB_B18D_41B7_874C92729A7A.label = Labile carbon album_6B9CECED_64CB_B18D_41B7_874C92729A7A_0.label = Labile carbon field test results with soil health ‘traffic light’ indicators album_6B9CECED_64CB_B18D_41B7_874C92729A7A_1.label = Organic carbon percentage album_6B9CECED_64CB_B18D_41B7_874C92729A7A_2.label = Toal nitrogen (kg/ha) panorama_D276948D_D8AB_1552_41CC_337231C73D00.label = Treatment 1: Grower standard practice, composting, minimum till, Japanese millet cover crop model_EBA02D15_E719_2D75_41D4_FDCBBB98D5CD.label = Treatment 1: Grower standard practice, composting, minimum till, Japanese millet cover crop panorama_D2712A9A_D8AB_1D76_41E1_24910B6EE464.label = Treatment 2: Grower standard practice, cover crop, cultivation, Buckwheat-vetch mix and Japanese millet cover crops model_EA012297_E43A_2D90_41D7_FF0AFCFE33B5.label = Treatment 2: Grower standard practice, cover crop, cultivation, Buckwheat-vetch mix and Japanese millet cover crops panorama_D2723861_D8AB_1DD2_41E7_6C3C37EDEE29.label = Treatment 3: Grower standard practice, composting, cultivation model_E9C4E5FA_E425_D793_41E7_43874E5F843B.label = Treatment 3: Grower standard practice, composting, cultivation model_E813F7B1_E42A_7391_41BC_2C41BC0F82C5.label = Treatment 4: Grower standard practice, cover crop, minimum till, Buckwheat-vetch mix and Japanese millet cover crops panorama_D272E47D_D8AB_75B2_41E0_99CC906B8937.label = Treatment 4: Grower standard practice, cover crop, minimum till, Buckwheat-vetch mix and Japanese millet cover crops ## Skin ### Button Button_71B3E41E_64CF_F08C_41CA_E2D57E627460.label = Labile carbon Button_71B3E41E_64CF_F08C_41CA_E2D57E627460_mobile.label = Labile carbon ### Dropdown DropDown_C6E8949B_E709_337C_41E9_338FCA3AF275.label = Menu ### Image Image_FC34C818_E73A_F37C_41E3_85B9DCC264AF.url = skin/Image_FC34C818_E73A_F37C_41E3_85B9DCC264AF_en.png ### Multiline Text HTMLText_74174190_64C8_B393_41D6_C49860F7EFA2_mobile.html =
What does labile carbon tell us?


Labile carbon is the carbon most readily available as a carbon and energy source to microorganisms.
While changes in practice may not demonstrate changes in total soil carbon, they may increase labile carbon, making it a better indicator of improved soil quality. Labile carbon is often a good ‘leading indicator’ of soil biological activity.
The labile carbon field test is useful for comparing management practices that influence organic carbon. A labile carbon test was undertaken across the different treatments within the trial and compared to the control area.
