ABSTRACT A 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 tak...
This study evaluates the fertility of small scale farmers’ field in Ijumu Area of Kogi State. The area lies within the Southern Guinea Savannah zone of Nigeria. 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 farme...
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 for Ikwo Upl...
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...
This research work was carried out on the rice soils of Ebonyi State, considering the Manganese distribution in upland, lowland and irrigated rice in the three Local Government Areas of Ebonyi State, namely; Abakaliki, Ikwo and Ivo LGAs in the three agricultural zones namely; Ebonyi North, Central and South. 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 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...
ABSTRACT The 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 anal...
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...
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...
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...
Abstract Cowpea (Vigna unguiculata [L]Walp) can obtain nitrogen from the atmosphere by the process of biological nitrogen fixation when associated with specific and effective rhizobia. The purpose of this study was to evaluate the effect of different rates of phosphate fertilizer on nodulation and dry matter yield of cowpea. A Randomized Complete Block Design with four treatments and three replications was used. The trial was conducted on the field. The treatments consisted of different ra...
Abstract Grain legumes are getting popular all over the world, either because of their high protein or oil content and potential to improve soil fertility. A field study was undertaken with two grain legumes; Soybean and Cowpea, that are economically important in the semi-arid region at the Irrigation Research Farm of Institute for Agricultural Research, Kadawa, Kano in the Sudan Savanna to gain an understanding of fertilizer application rates on nodulation and yields of Soybean (TGx 1904-6F)...
ABSTRACT One of the most serious problems currently affecting agricultural production in developing countries especially Nigeria is land degradation. The adverse effect of land degradation on soil production, soil health and food security is an important current global issue. Hence, this study assessed the chemical degradation of soils under kolanut production with the view of optimizing its production through appropriate management practices that is environmentally friendly and sustainable. ...
