Amend the soil with bacteria or fungi
A controlled, randomized, replicated experiment from 1996 to 2008 on clay-loam soil in southern Turkey (Celik et al. 2010) found 24% higher organic matter content in soil under mycorrhizal-inoculated compost applications compared to the control. The largest soil aggregations were found under mycorrhizal-inoculated compost (0.11 mm), manure (0.05 mm) and compost (0.07) applications. Crop yield was highest under mineral fertilizer (13720 kg/ha) followed by manure (10500 kg/ha), compost (8780 kg/ha) and mycorrhizal-inoculated compost (7630 kg/ha), compared to the control (5900 kg/ha). Within a wheat Triticum aestivum-maize Zea mays rotation were three replicates five 10 x 20 m treatments: control, mineral fertilizer (300-60-150 kg N-P-K/ha), manure (25 t/ha), compost (equal mixture of grass, wheat stubble and plant leaves, 25 t/ha), mycorrhizal Glomus caledonium-inoculated compost (10 t/ha). Soil samples were taken to 30 cm depth 2008.

Amend the soil with manures and agricultural composts
A controlled, randomized, replicated experiment from 1996 to 2008 on clay-loam soil in Turkey (Celik et al. 2010) found 69%, 32% and 24% higher soil organic matter content in soil under manure, compost and mycorrhizal-inoculated compost applications respectively, compared to the control. Mineral fertilizer had no effect on organic matter accumulation. The largest soil aggregations were found under manure (0.05 mm), mycorrhizal-inoculated compost (0.11 mm) and compost (0.07 mm) applications. The lowest soil density was under compost (1.1 Mg/cm3) compared to the control (1.4 Mg/cm3). Lower penetration resistance was found under compost (1.06 MPa) and manure (1.17 MPa) application, with the highest under mineral fertilizer application (1.29 MPa) and in the control (1.51 MPa) plots. Combined wheat Triticum aestivum and maize Zea mays yield was highest under mineral fertilizer (13,720 kg/ha) followed by manure (10,500 kg/ha), compost (8,780 kg/ha) and mycorrhizal-inoculated compost (7,630 kg/ha), compared to the control (5,900 kg/ha). Within a wheat-maize rotation were three replicates of five 10 x 20 m treatments: control, mineral fertilizer (300-60-150 kg N-P-K/ha), manure (25 t/ha), compost (equal mixture of grass, wheat stubble and plant leaves, 25 t/ha), mycorrhizal Glomus caledonium-inoculated compost (10 t/ha). Soil samples were taken to 30 cm depth 2008.
