Digital Soil Mapping of Soil Taxonomic Classes: Prospects and Challenges for Machine Learning Integration in Nigeria

Yasin Agono Awwal^*, Lemuel Musa Maniyunda, Sulaiman Lawan Ya'u, Muhammad Isma'il

Reliable spatially explicit soil information is important for land-use planning, agricultural management, and food-security planning in Nigeria. Digital soil mapping (DSM), which combines soil observations with environmental covariates through spatial prediction functions, provides an opportunity to complement and progressively update existing soil information. This review examines the prospects a...

Laboratory Assessment of Basalt Dust Incubation on the Physical Properties of Contrasting Soils in Nigeria

IBRAHIM RASHEED^*, Akinbile Oluwakunmi Christopher, Ewulo Babatunde Sunday, Ayodele Olumuyiwa Owolabi, Audu Luqman Muhammed

The effects of different application rates, particle sizes, and incubation periods of basalt dust on the selected physical properties of contrasting soils incubated for 90-day was evaluated in this study. A factorial arrangement with a 4×2×4 completely randomized design (CRD) with three replications was adopted. Air-dried and sieved soil samples collected from Auchi and Agbede town were treated ea...

Effect of NPK and poultry manure on selected soil properties, and performance of snake tomato (Trichosanthes cucumerina) in Wukari, Taraba State, Northeastern Nigeria

Waizah, Y.^*, JOHN WAMARHYEL GUNDIRI

This study was conducted to investigate the effect of NPK and poultry manure (PM) on selected soil properties and performance of snake tomato. The experiment was laid out in a randomized, complete block design with four treatments and three replicates. The treatments are 240 kg/ha NPK 15:15:15, 20 tons/ha PM, 120 kg/ha NPK 15:15:15 + 10 tons/ha PM, and control. The soil was loamy sand with low OC,...

Effects of NPK fertilizer on growth and yield of Nigerian turmeric (Curcuma longa linn.) germplasm in coastal rainforest ecology of Nigeria

Ekwere, E.O.^*, Baiyeri, K.P, Ogbonna, P.E, Olojede, A. O, Ekwere, U.A.

The study investigated the responses of 10 Turmeric Nigerian Curcuma Longa (NCL) Germplasm, to NPK nutrient rates and its effect on some soil properties. The experiment laid out, was a 3 x 10 factorial in RCBD, to evaluate the growth and yield performance on coastal rainforest soil in Nigeria. The following data were collected: soil physico-chemical properties, tiller count, leaf area (cm2), plant...

Effect of Untreated Petroleum Refinery Effluent on Bacterial and Fungal Population of Soil and Seedling Growth of Maize (zea Mays L.) in an Ultisol.

Ogbemudia l^*, Ogboghodo, I. A, Edosa, Ifeyinwa Valerie1, Ekiduefe O. R.

This trial was conducted to investigate the effect of applying untreated petroleum refinery effluent on bacterial and fungal population and seedling growth of maize in an utisol. 2 kg of soil from an uncultivated land was measured into 12 pots which were then polluted with untreated refinery effluent at the rate of, 0, 50, 100, 150 milliliters, these treatments were replicated three times and laid...

Characterization and Classification of Soil - Landform Features in Nigeria's Sokoto - Rima Floodplains

Talha I. Z^*, Noma, S. S, Ibrahim Babagana Buji, Danmowa N. M, Adamu I.

The study was to identify and classify soils in floodplains along the Wamakko area of Sokoto-Rima in Nigeria. After profiling, samples taken from each horizon were identified, characterized, and classified into four soil types: pedons 1 and 4 (Vertisols) and pedons 2 and 3 (Entisols). The results indicate an ideal pH range for most agronomic crops on the surface and subsurface horizons (pH 6.2–6.9...

Evaluation of Furrow Infiltration by Swartzendruber and Horton’s Models in Northern Guinea Savanna of Nigeria

Aminu H G^*, Mudiare, O. J, Oyebode M. A, Aisha Abdulkadir, Aminu Z

The study aimed at evaluating two models (Swartzendruber and Horton) using furrow infiltration data measured in Samaru, Zaria. These measurements were carried out on the three-field plots A, B and C. Infiltration parameters were generated from the data measured from plots A and B and fitted into the models for predictions of water infiltrated depths at different time intervals. The predictions fro...

Evaluation of Soils on a Toposequence Formed from the Coastal Plain Sands of the Imo River Basin, Southeastern Nigeria

Madueke, C.O^*, Nnabude, P.C., Okore, I.K, Onunwa A.O., Madueke, E.C, Okafor, M.J, Nnabuihe, E, Nwosu, T.V

Due to the increasing land degradation in southeastern Nigeria – with particular reference to the ubiquitous gully network in the region – selected soils formed from the Coastal Plain Sands of the Imo River Basin were evaluated and char- acterized to determine their potentials and capabilities. , Three profile pits were consequently dug on the upper slope (Umuariam), -mid-slope (Umulogho), and foo...

Effect of Land - Use on Particulate Organic Carbon and Carbohydrates Distributions in Dry - and Wet - Sieved Stable Aggregates in an Ultisol

Udom B. E.^*, Simon U. G.

Particulate organic carbon (POC) and carbohydrates (R-CHO) distributions in dry- and wet-sieved aggregates in four land-use types in southern Nigeria were studied. The land-use types were: secondary forest, 5-year fallow plots, cocoa plantation, and 5-year continuous cultivation. The results showed that land types affected soil organic carbon fractions, soil organic carbon density, bulk density, a...
