Agronomic Potentials of Boiler Ash Derived from Oil Palm Wastes as Fertilizer, Soil Amendment, and Liming Materials

Ezema Raymond Anikwe*, Asadu Charles Livinus, N. A. Onunka, Ifejimalu, A. C

One potential problem with recycling power plant ashes is its variability both from fuel to fuel and within a certain fuel-type. This study obtained information on the main components of ashes derived from burning oil palm mill wastes in boilers for energy generation to obtain reference data for the development of its utility possibilities with particular emphasis on use as fertilizer, soil amendm...

Agronomic and Economic Evaluation of Different Conservation and Conventional Farming Practices on a Sandy Clay Loam Soil at Minna, Nigeria

Odofin A. J.*, Kaure I. G., Tanko L., Eneje R. C

Field trials were carried out in 2008 and 2009 cropping seasons to compare manual ridging (control) with ten conservation and conventional farming practices. The zero tillage treatments recorded significantly higher penetration resistance than manual ridging in both years. In terms of soil moisture content, seedling emergence, plant height, grain yield and stover + grain yield, however, the contro...

Effect of Organic Manure Source and Time of Application on the Field Performance and Nutrient N Uptake of Ginger in the Guinea Savanna

Nwaogu E.N.*, Nwauzor E.C, Mohammed M.

The influence of organic manure from different sources applied at different time intervals before planting on the rhizome yield and nutrient N uptake of ginger was evaluated in 2009 and 2010 cropping seasons at the National Root crops Research Institute, Umudike. Treatments consisted of organic manure from three sources (Poultry manure, Rice mill waste and Cow dung manure) factorially combined wit...

Comparative Potential Effects of Biochar, Compost and Inorganic Fertilizer on Major Nutrient Ions Mobility and Stability in Screen - House Irrigated Maize in the Drier Savannas of Nigeria

Dawaki M. U.*, Aliyu Abdulqadir, Bassam Abdulrahman Lawal

A screen-house experiment was conducted in the dry season of 2017 to evaluate the potential effect of organic and inorganic soil amendments on the mobility and stability of significant plant nutrient ions. 5 t ha-1 compost or Biochar were applied to pot-grown maize to compare their effect with NPK at the rate of 120: 60: 60 kg ha-1 and a control. Soil solution was sampled with lysimeters at varyin...

Biochar and Composted Poultry Manure Causes on Immobilization and Migration of Heavy Metals in Maize Plants Beside a Mining Site.

Okoro, I. G.*, Nwachukwu, O. I

Mining sites in Amagu-Enyigba Ebonyi state Nigeria have deposits of heavy metals especially lead and zinc. Most crops grown in such sites are always hyperaccumulators of these metals. It is against this backdrop that the present study was conducted. The study aimed to ascertain the effect of biochar and composted poultry manure in immobilizing metals in the soil and subsequent reduction in maize u...

Effect of Organic Soil Amendments on Soil Chemical Properties in Sudan Savannah of Nigeria

Aliyu Abdulkadir*, Mansur U. Dawaki, Mahmud Sani

Composite soil samples were collected from irrigated maize fields, to study the effect of Bio char and Compost on post-harvest soil chemical properties in the Sudan Savannah of Nigeria. Laid on a completely randomized block design, the treatments used in the experiment were 5tha-1 Bio char, Compost, and Control. Pre-amendments application and post maize harvest soil characteristics obtained from l...

Soil Research in Nigeria: Response to Local Needs or Bandwagon Effect of Global Trends? a Quantitative Analysis of Three Decades

Nwachukwu O. I.*, Nwachukwu I.

A critical study of soil research in Nigeria from 1980 – 2014 was conducted based on published original research within the period, and this was compared with studies conducted in USA, Europe, China and worldwide. The focus of Nigerian soil research was evaluated in the light of local agricultural needs, national policies, and global trends. The tool used to search online databases was Google scho...

Lowland Rice Yield Responses to Variation in Water Management in a Sudan Savannah Soil of Nigeria

Girei, A. H.*, Nabayi, A.,, Amapu I. Y, Mudiare, O. J, Abdulkadir, A .

This study investigates the applicability of reduced water management (alternate wetting and drying AWD) practice alongside continuous flooding (CF) which is the traditional water management practice of lowland rice production in Sudan savanna ecological zone of Nigeria. Rice growth component variables from each of the management practice were compared to identify the best in terms of re- duced nu...

Restorative Effects of Amendments on Artificially Degraded Soils in the Southern Guinea Savanna of Nigeria

Adaikwu A.O*, F. K. Salako, Busari M. A., Jamiu Oladipupo Azeez

An evaluation of the productivity of degraded alfisols at Makurdi and Otobi, Nigeria, using artificial desurfacing techniques (ADT) was carried out in 2012 and 2013 cropping seasons. The study was a split-split plot experiment arranged in a Randomized Complete Block Design with three replications. The soil was desurfaced at 0 – 5, 0 – 10, 0 – 15, 0 – 20 cm and the undesurfaced soil, 0 cm (control)...
