Strategies for reducing the fertilizer application rate in the ridge and furrow rainfall harvesting system in semiarid regions

Abstract The ridge and furrow rainwater harvesting (RFRH) system is a promising water-saving planting technique for dryland farming, but we lack a full understanding of the effects of different fertilizer rates (N:P) on plant nutrient uptake and nutrient use efficiency (NuUE) in foxtail millet using...
