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...

Effect of phosphate fertilizer application on manganese adsorption by some soils in Borno state

Abstract-The  study  was  carried  out  to  investigate  the effect  of  phosphate  fertilizer  application  on  manganese (Mn)  adsorption.  Composite  sandy  loam  and  loam  soil samples  (0-20  cm)  were  collected  from  Dalori  and Gongulong  and  analysed  for  their  texture  and  chemical properties.  Mn  adsorption  experiment  was  carried  out. Loamy soil  collected  at  Gongulong was  moderately acidic in  reaction,  moderate  in  e...

AN ASSESSMENT OF SOME SOIL QUALITY INDICATORS IN DEKINA LOCAL GOVERNMENT AREA OF KOGI STATE A CASE STUDY OF ABOCHO, EGUME, AND OJIKPADALA

ADDITION OF DIFFERENT LEVELS OF POULTRY MANURE ON TOTAL HETEROTROPHIC BACTERIA IN A CULTIVATED SOIL

ABSTRACTA laboratory experiment was set up at Kogi State University Anyigba at the faculty of Agriculture, department of soil and environmental management Laboratory to evaluate the effect of different levels of poultry manure on total heterotrophic bacteria in a cropped soil. Soil samples were collected from many random points at the Kogi State University Teaching and Research Farm at a depth of 0-15cm using an auger. The collected samples were bulked into one composite sample which was take...

The study area is having three districts; Ijumu Oke, Ijumu Arin and Gbedde. 60 farmers were identified through the Agricultural Development Agency and questionnaires were administered to them to identify soil management practices and problems among the farmers. Soil samples were collected from three farmers’ field, one farmer ...

Cations Ratios Distribution in Selected Rice Soils of Ebonyi, Southeastern Nigeria

This research work was carried out on the rice soils of Ebonyi State, considering the cation ratios distribution in upland, lowland and irrigated rice in the three agro-ecological zones of Ebonyi, namely; Ebonyi North, Ebonyi Central and Ebonyi South. The location at Ebonyi North was at Amachi Izzi in Abakaliki and designated by AUP, ALP and AIP for Abakaliki Upland, Lowland and Irrigated pits respectively. Ebonyi Central was located at Ikwo and designated by IUP, ILP and IIP f...

APPLICATION OF DIGITAL ELEVATION MODEL (DEM) IN SUITABILITY EVALUATION OF SELECTED SOILS OF IKWO – SOUTHEASTERN NIGERIA FOR RICE PRODUCTION

The study was carried out at Agubia Ikwo in Central Ebonyi State and aimed at using Digital Elevation Model (DEM) in suitability evaluation of some selected soils for rice production. Three rice growing soils were identified in the area which include upland, lowland and irrigated rice soils. Three profile pits were sunk in each of the three rice cropping soils summing up to a total of 9 profiles. Suitability evaluations indicated that soil climatic requirements as well as soil physical condit...

In the different locations, upland (UP), lowland (LP) and irrigated (IP) uses were considered. They were identified as AUP, ALP and AIP for Abakaliki IUP, ILP and IIP for Ikwo and IvUP, I...

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 dug in eac...

The impacts of agroforestry practices on soil fertility in rural areas

ABSTRACTThe concern of humanity is the need to tackle the increasing challenges of severe land degradation and desertification of the ecosystem. The study examined the impacts of agroforestry practices on soil fertility in rural areas of Katsina State, Nigeria. Purposive sampling technique was employed in collecting data from one hundred (100) rural farmers with structured questionnaire administered in two Local Government Areas of Katsina State, namely Batsari and Safana. The data were analy...

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...
