实施低投入矿物肥料微剂量技术的报告显示，产量增加了120%。然而，在碳含量低（0.2%）的酸性萨赫勒土壤（pH 4-5（H2O））上，问题是施用如此小的剂量是否会导致多年的养分开采，ICRISAT计划进行三项研究，每项研究为期3年。试验1（2003）和2（2008）涉及三种种植密度，两个珍珠粟品种和四种施肥管理方案，在试验1中去除作物残留物。试验3（2010）设4个有机无机肥配比和10个谷子品种。有机和矿物投入都是丘陵施用的。
Reports from implementation of the low-input mineral fertilizer microdosing technology have shown up to 120% yield increase. However on the acidic Sahelian soils (pH 4–5 (H2O)) with low carbon content (0.2%), the question is whether applying such small dose would not lead to nutrient mining over years, which ICRISAT set three studies of 3 years each to address. Experiments 1 (2003) and 2 (2008) involved three planting densities, two pearl millet varieties and four fertility management options with removal of crop residue in experiment 1. Experiment 3 (2010) involved the combinations of 4 rates of organic and mineral fertilizers and 10 millet varieties. Both organic and mineral inputs were hill-applied.
