Residual effects of repeated animal manure application on coarse-textured Ultisol, nutrient uptake and cucumber yield

One of the main UN Millennium Development Goals is eradication of poverty and hunger through food security. Unfortunately, this goal is difficult to achieve in Nigeria due to soil degradation, low soil fertility, and other agricultural challenges. The current research on food security in Nigeria is focused on improving soil fertility using low-cost organic amendments.
