The Classification of Some Nigerian Soils
TLDR
In this article, the authors presented data on soil profile samples from eleven sites in Nigeria, widely distributed from the high rainfall coastal area of sedimentary parent material to the dry northern area where aeolian deposits from the Sahara Desert have been a major soil-forming factor.Abstract:
This study presents data on soil profile samples from eleven sites in Nigeria, widely distributed from the high rainfall coastal area of sedimentary parent material to the dry northern area where aeolian deposits from the Sahara Desert have been a major soil-forming factor. Weatherable minerals are generally present in the soils formed from crystalline rocks and most of these soils are classified as Alfisols. On the sedimentary rocks and on the ultrabasic crystalline rocks Oxisols have formed. On aeolian parent materials from the Sahara and on the Pleistocene sediments the soils are classified as Inceptosols.read more

EFFECT OF ORGANIC AND INORGANIC FERTILIZER ON YIELD AND CHLOROPHYLL CONTENT OF MAIZE (Zea mays (L.) AND SORGHUM Sorghum bicolour (L) Moench)
TL;DR: In this paper, the effects of amending soil with organic (poultry manure) and inorganic fertilizer on yield and chlorophyll content of maize and sorghum was carried out at the Teaching and Research (TR was highest under control plots in both crops.

Effect of organic and inorganic fertilizer on yield and chlorophyll content of maize ( Zea mays L.) and sorghum Sorghum bicolour (L.) Moench)
TL;DR: Drought tolerance measured as percentage chlorophyll stability index (CSI%) was highest under control plots in both crops and in both maize and sorghum, the lowest chlorophyLL content occurred in control plot.

Aggregation and organic matter fractions of three Nigerian soils as affected by soil disturbance and incorporation of plant material
TL;DR: In this paper, the authors examined the changes in soil structure in response to SOM fractions dynamics in an incubation experiment and found that the incorporation of plant material significantly increased the light fraction organic matter (LFOM) with density −3 but had no effects on the heavy fraction polysaccharides (HFPS).

Infiltration of water into two nigerian soils under secondary forest and subsequent arable cropping
G.E. Wilkinson,P.O. Aina +1 more
TL;DR: In this article, the authors found that horizontal flow was difficult to restrain apparently due to the presence of horizontally oriented micro-fauna channels in the plough layer and greatly reduced the tendency for horizontal flow from a normal double-ring infiltrometer system during arable cropping.

N-use efficiency of single, double and synthetic maize lines grown at four N levels in three ecological zones of West Africa
TL;DR: The hybrids were more efficient in N-use and its component traits than the synthetic cultivar, and yielded the most grain as well as exhibiting superior traits for N-uptake and N- use efficiency.
