Known as the most heat-adapted legume with excellent drought tolerance, which can largely be attributed to it’s stout tap root. Cowpea roots have been documented at penetrating over 8 ft. into the soil profile, which is far superior to soybean roots. Cowpeas attract benefical insects even without flowering because they excrete extra-florel nectar through small pores in the stems and leaves. Cowpeas are known to generally preform better in acidic soils than alfalfa and clover species. N production is so pronounced, that it’s one of few legumes that will leave the soil with a positive N credit, even if the seed is harvested. Observations have shown significant reductions in root-knot and soybean nematodes after a cowpea crop.
