This study was conducted to evaluate the physic-chemical properties of sokoto Rima River to see if the 2010 flooding had any effect in the fertility status of these soils. Eight samples were collected at the depth of 0-15 and 15-30cm each from the...

Beye, G., 1977: Influence of duration of flooding prior to transplanting and straw incorporation on physico-chemical properties of two rice soils, and on rice development and yield. Six-year field trials indicated that flooding had no unfavourable effect on soil pH or redox potential, in the presence or absence of incorporated straw. Straw had a positive effect on rice growth and yields on both soils (sandy and grey sandy loa...
