Fertility Status of Biakpan Rubber (hevea Brasiliensis) Soils of Cross River State, Nigeria

Kekong, M. A.*

A study was carried out at Biakpan rubber estate in Cross River State, Nigeria to evaluate the fertility status of the soils. Three profile pits at random points within the estate were sunk representing the crest, the middle slope, and the valley bot- tom. Five samples were collected from each profile at 0 – 25cm, 25 – 50cm, 50 – 75cm, 75 – 110cm and 110 – 170cm depth. Fifteen representative soil ...

Influence of Forms of Iron and Manganese Oxides on the Physical and Chemical Properties of Soils Formed Over Mica - Schist in a Northern Guinea Savanna, Nigeria

Kefas, P. K*, Abdulrashid Shobayo Babatunde, Ofem, K.I, Akwoga, J.A, Asadu Charles Livinus, , Ezeaku, P.I.

Three forms of oxides of iron and manganese were evaluated on soils developed in mica-schist lithology within the basement complex formation of Taraba State, North-eastern Nigeria. The results from the three oxide forms namely, pyrophos- phate extractable (Mnp/Fep), oxalate extractable (Mnox/Feox) and citrate- bicarbonate-dithionite extractable (Mnd/Fed) examined were subjected to both descriptive...

Influence of Sesame Varieties and Fertilizer Levels on the Yield of Sesame in Potiskum, Yobe State - Nigeria

Usman, M.*, A. Ali, Olatunji O

Field experiments were carried out in 2018 and 2019 cropping seasons to deter- mine the influence of sesame varieties and fertilizer levels on the yield of sesame in the study area. Treatments consisted of three varieties of sesame (Jigida, NCRIBEN-01M and NCRIBEN-032) and four levels of NPK 15:15:15 fertilizer (0, 50,100 and 150 kg ha-1). Treatments were laid out in a randomized complete block de...

Mineralogical Investigation of Some Imperfectly and Poorly Drained Soils of the Nigerian Northern Guinea Savanna Agroecology

Abdulrashid Shobayo Babatunde*, Sulaiman Yau Lawan, Aliyu, J.,

This study aimed to investigate the mineralogy of soils with impaired drainage formed within the northern guinea savanna of Nigeria. Soil survey procedure was carried out to identify the two soil individuals (polypedon) namely: imperfectly drained soil (IDS) and poorly drained soil (PDS) that occupied 6,407.68ha (90.96%) and 636.82 ha(9.04%) respectively. In each soil individual, a repre- sentativ...

Characterization and Classification of Rice - Growing Soils on Igbaku Sandstones Residua and Current Suitability for Rice Production in Anambra State, Eastern Nigeria

Asadu Charles Livinus*, Onyeme E

"The soils on Igbaku sandstones residua were sample at Ifite Ogwari in Anambra state Nigeria to characterize, classify and evaluate their current suitability for rice production. Following several auger borings, a modal profile was sited dug, de- scribed and sampled. Data from it and representative auger points are presented. The soils generally belong to loamy textural classes or finer, especiall...

Effect of Nypa Fruticans and Mangrove Species on Soil Properties in Eastern Obolo, Akwa Ibom State

Ogban P. I.*, Dickson, U. S, Ebong, U. P

The study was conducted to evaluate the effect of nypa and mangrove on soil properties to determine whether nypa in displacing mangrove was degrading or aggrading the underlying soil, in Okorombokho Community in Eastern Obolo Area of Akwa Ibom State. The study was carried out in three contiguous loca- tions, namely, mangrove (M) forest, nypa and mangrove (N&M) forest, and bare plot with neither ma...

Effect of Trichoderma Inoculated Organic Manure on Water Retention Characteristics of Two Texturally Contrasting Soils in Nsukka, Southeastern, Nigeria

Azuka, C.V.*, Oka, S. C

The effect of Trichoderma inoculated organic manure on water retention charac- teristics of two texturally contrasting soils was investigated in the glasshouse of the Department of Soil Science, University of Nigeria, Nsukka. The study in- volved two texturally contrasting soils, sandy loam (SL) and loamy sand (LS) amended with poultry manure (PM) at three rates (10 t/ha, 20 t/ha and 30 t/ha) and ...

Maximum Phosphate Adsorption Capacity as Influenced by Some Biochar Properties

Abdu N*, Solomon, R. I., Yusuf, A. A, Bello M.

The use of biochar as a low-cost adsorbent to remove nutrients from aqueous solutions is getting great attention lately due to its many environmental applica- tions and benefits. Although biochar has been widely used to remove phosphate from aqueous solutions, inconsistencies still exist with regards to biochar proper- ties responsible for the adsorption process. This research was therefore, carri...

Evaluation of Lower Niger River Floodplain Soils of Bayelsa State, Southern Nigeria for Their Agricultural Capabilities

Achimota A. Dickson*, FunsoR. Kutu, Joseph Aruleba

Capabilities and fertility constraints to crop production of the Lower Niger River floodplain soils were assessed using Land Capability Classification (LCC), Land capability Index (LCI), and the Fertility Capability Classification (FCC) systems. The LCC grouped the nine soil mapping units (SMUs) into class II, suited for a wide range of arable crops while LCI grouped ELM1 into class I, ODN1 and TF...

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...
