Comparing the Effect of Biological Amendments and Chemical Fertilizer on Bacterial and Fungal Population

Edosa, Ifeyinwa Valerie^*, Aleladia B. O, Osarhiemen, V. O.

Amelioration of degraded soils has triggered interest regarding alternatives to supply nutrient and improve microbial diversity through the integrated use of organic manure and biofertilizers. In this light, a screenhouse experiment set in a completely randomized design (CRD) with seven (7) treatments, Bacillus thurin- giensis (5 ml), digestate (22.4 t ha-1), 50% of digestate + NPK 15:15:15 (11.2 ...

Performance of Horton Infiltration Model in Predicting the Infiltration Capacity of Some Soils of the Sudan Savanna of Nigeria

Abubakar Halilu Girei^*, Nabayi, A.,, Aliyu, J.,, Garba, J,, Hashim, S.A.,, Alasinrin, S.Y., Abdullahi, M Y

Infiltration study is very crucial in modelling water requirement of crops during their growth season. Infiltration rate measurements were carried out on dryland areas of Sokoto, Sudan savanna ecological zone of Nigeria, using the double ring infiltrometer. Disturbed and undisturbed soil samples were used to determine some physical characteristics (Texture, Saturated hydraulic Conductivity, partic...

Assessment of the Water Conservation Potential and Mode of Application of Coconut (cocos Nucifera) Husk Hydrogel on Soil Cultivated to Coconut Seedling

M.O. Ekebafe^*, L. O. Ekebafe, OSAYANDE P.E., MAIDOH F.U., Irhemu P.

Coconut husk cellulosic-polyacrylonitrile hydrogel was synthesized in aqueous solution. Saponification of grafted copolymer was done by reaction with sodium hydroxide followed by methanol precipitation. The reaction was confirmed using FTIR and characterized in terms of water retention value (286g/g) and de-swelling ratio (83.16%). Soil samples collected were prepared and analyzed for physico-chem...

Utilization of Ashed Cocoa Pod Husk and Urea Fertilizer on Growth and Dry Matter Yield of Coffee on Alfisol in Ibadan

AKANBI Olorunfemi Sunday Ojo^*, OJENIYI STEPHEN OLUSOLA, Famaye, A. O., Ipinmoroti, R.R.,, Ibiremo, O.S.,

A trial was conducted on sandy clay, slightly acidic, low organic carbon (C) and available phosphorus (P) soil to evaluate the effect of ashed cocoa pod husk (ACPH) and urea fertilizer on the growth and dry matter yield of coffee under greenhouse condition at Cocoa Research Institute of Nigeria (CRIN), Ibadan in 2011. The treatments consist of ACPH applied at 5, 10, 15 and 20 Kg N ha-1, urea (10 K...

Geostatistical investigation and GIS-based spatial distribution of some micronutrients in Wukari soils, Taraba State, Nigeria

Waizah, Y.^*, Adashu Tanko Gani

Mapping soil fertility is important for site-specific nutrient management, it gives an insight into soil nutrient content, which is crucial for land use planning, fertilizer recommendations, and sustainable management of soil resources. Micronutrient deficiency in the soil is a serious limitation for crop production. Evaluation and mapping the soil micronutrients of a particular area can be a poss...

Spatial Multi-Criteria Evaluation of Land Suitability for Rainfed Cowpea (Vigna unguiculata L. Walp.) Production in Kambriwa, Kaugama LGA of Jigawa State, Nigeria

Alkasim Abdulkadir^*, Magaji M. J, Abdulrahman B. L., Salihu Ahmad Pantami

Improving cowpea productivity in the semi-arid Sudan Savanna requires spatially explicit information on land resources to support agricultural planning and soil management. This study evaluated the suitability of land for rainfed cowpea (Vigna unguiculata (L.) Walp.) production in Kambriwa, Kaugama Local Government Area, Jigawa State, Nigeria, using a Geographic Information System (GIS)-based Mult...

Analysis of the Potential Soil Parent Rock Resources and Ecological Footprint in Jadaka, Kandahar, Kargo, Makada and Sarki Aska Villages of Dutse, Nigeria

Suleiman Usman^*

A study of the parent materials and ecological analysis, covering five sites of Dutse area in Jigawa State, Nigeria was undertaken, applying the concepts of visual assessment and ecological footprint to describe the biophysical condition of the rock particles and human economy. The objectives of the study were to classify the basic parent rocks and ecological footprints around them and to draw con...

Assessment of Land Use Pattern and Land Form on Selected Physico-Chemical Properties of Soils Developed on Basement Complex-Sedimentary Transitional Zone of South Western Nigeria

AJIBOYE G. A.^*, OLANIYAN J. O., BOSIAKO C., OYETUNDE O. O.

The effects of cropping practices and soil management on the properties of basement complex- sedimentary transitional zone soils in South Western Nigeria was assessed using soil samples from the pedogenic horizons of ten profile pits dug on two land-use systems (subsistence and experimental farms) and two toposequence. The land use significantly (P
