  1. Amend the soil using a mix of organic and inorganic amendments

    A controlled, randomized, replicated experiment from 1988 to 2008 on sandy loam in northeast China (Lou et al. 2011) found more soil organic carbon under manure and manure plus nitrogen/phosphorus/potassium (NPK) fertilizer (18. 5 and 19 g C/kg respectively) compared to the control (11.8 g C/kg). Microbial biomass was higher in the manure (846 mg/kg) and manure plus NPK fertilizer treatments (885 mg/kg) than in the remaining treatments (496, 472 and 426 mg/kg for NPK, nitrogen-only and control treatments, respectively). Throughout the experiment celery cabbage Brassica rapa, frijole Phaseolus sp., radish Raphanus sativus, potato Solanum tuberosum, cucumber Cucumis sativus, onion Allium cepa, beet Beta vulgaris, tomato Solanum lycopersicum, mustard Brassica sp., and aubergine Solanum melongena were grown in rotation. Treatments included an unfertilized control, nitrogen fertilizer, NPK fertilizer, organic manure (horse compost) alone, and organic manure combined with NPK fertilizer. Plots were 1.5 m2 and replicated three times.
