Background and Objective: Aquic Arenic Paleudults soils are developed at valley bottom of a basement complex parent material of the sub-humid tropical rainforest. The aim of the study was to determine the mineralogy of clay components of Aquic Arenic Paleudults soils of Akpamkpa, Southeastern Nigeria. Materials and Methods: The study mineralogy of clay components of Aquic Arenic Paleudults soils of Akamkpa, southeastern Nigeria was carried out on 50 hectare land. Two soils were collected fro...
Predictive Mapping of Soil Properties for Precision Agriculture Using Geographic Information System (GIS) Based Geostatistics Models
In precision Agriculture, geostatistical methods as a predictive tool have been extensively utilized. The approach estimates soil properties spatial variability and dependency. This study was carried out in Ovia north east Local Government Area of Edo State of Nigeria in order to map soil properties (Sand, Clay, pH, OC, P, N and CEC) and predict their spatial variability. Twenty-nine (29) soil samples were collected randomly from Typic Kandiudults soil type under three different land use, tea...
Land evaluation, characterization and classification of soil for the proposed oil palm plantation in Ekpri Ibami, Akamkpa Local Government Area, Nigeria
Land evaluation, characterization and classification of soil for the proposed oil palm plantation in Ekpri Ibami, Akamkpa Local Government Area, Nigeria was conducted on 50 ha of land using a combination of both conventional and digital survey methods. The objective of the research was to characterize, classify and evaluate the land for the proposed oil palm production. Three soil mapping units were identified (EKP I, EKP II and EKP III) and representative profile pits were du...
Effects of Neem-Based Organic Fertilizer, NPK and Their Combinations on Soil Properties and Growth of Okra (Abelmoschus esculentus) in a Degraded Ultisol of Calabar, Nigeria
A field experiment was conducted at the University of Calabar Teaching and Research Farm toevaluate the effects of neem-based organic fertilizer, NPK and their combinations on soil chemicalproperties and growth of okra (Abelmoschus esculentus) on a degraded Ultisol Calabar. Theexperiment was laid out in a randomized complete block design with three replications comprising ofsix treatments. The treatments were control (no amendment), sole NPK 20:10:10 fertilizer andneem–based organic fertili...
Status and distribution of soil available micronutrients along a hillslope at Ekpri Ibami in Akamkpa Local Government Area of Cross River State, Nigeria
A field study of the status and distribution of available soil micronutrients along a hillslope of EkpriIbami was carried out on a 50 ha land. The aim of the study is to evaluate the micronutrient status anddistribution and their relationship with some selected soil properties. A total of 16 soil samples werecollected from each pedogenic horizons of four profile pits dug along a hillslope classified as upperslope, middle slope, lower slope and valley bottom. The micronutrients determined in t...
Interaction between some soil physicochemical properties and weather variables on sub-humid tropical rainforest soils of Cross River State, Southeastern Nigeria.
The study deals with the interaction between some soil physicochemical properties and weather variables on sub-humid tropical rainforest soils of Cross River State, Southeastern Nigeria. The study aims to determine the interactions between soil properties and weather variables of three land uses occurring on the tropical sandy soils. Soil samples were obtained from 10,000 m2 of UNICAL Teaching and Research farm (Arable farm), Oil palm plantation and Forestry Teaching and Research farm (F...
