    • ...Continuously growing of cassava on the same soil without sufficient fertilizer or manure inputs will gradually decline the soil productivity due to depletion of nutrients (Howeler, 2002)...

    • ...Bitter manioc grows well in very acid, nutrient poor soils without external inputs, although yields may begin to decline with consecutive cropping due to K deficiency (Howeler 2002)...
    • ...The presence of N2-fixers also increased biomass of manioc stems and tubers in both the fertilized and unfertilized treatments after one year (Fig. 4); a result different from Howeler (2002) that did not report significant differences for manioc tubers between control and NPK fertilization in Colombia until harvest in the third consecutive year of cropping...
    • ...Presently, there is conflicting evidence regarding increased N uptake by manioc with fertilization or in the presence of N2-fixers (Howeler 2002; Carsky and Toukourou 2005)...
    • ...In Colombia, foliar N concentrations of manioc did not respond to NPK fertilization but stems and tubers both had increased N concentrations (Howeler 2002)...

    • ...Cassava is an important food security crop as well as a tradable food crop and is well-adapted to poor soil fertility (Howeler 2002), which could explain why it has become a dominant crop over time...

    • ...Cassava is a heavy potassium feeder, but also requires nitrogen, phosphorus and meso-/micro-nutrients to produce good yields (Howeler 2008, 2002; Nguyen et al. 2002)...
