Soils of the Degraded Derived Savanna Land in Southwest Nigeria: Distribution, Morphology and Sustainable Climate–smart Land Use Plan

Okusami, Temitope A.*

Southwest Nigeria belongs to the humid tropical climate with a Wet/Dry Forest and a Derived savanna. The studied site is under the latter ecosystem (located around Ilero, 08.05N/03.22E in Kajola Local Government Area of Oyo State) and was a former mechanized farm with low-intensity land use pattern with seasonal uncontrolled burning/grazing with a subsequently degraded landscape. And to encourage ...

Soil Suitability Evaluation for Maize in Lere Local Government Area of Kaduna State Nigeria

Magaji M. J*, Samndi M. A., Ado A A, Buji I. B., Abubakar M. A.

The soils of Lere (Saminaka) in Kaduna state, Northern Guinea Savanna climatic zone were evaluated for suitability of maize (Zea mays) cultivation, employing various methods. Data were obtained through field study and laboratory analyses. Three soil Units were delineated, and one profile was sunk in each of the soil units. The profiles were described according to the USDA soil survey manual, and s...

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,...

Soil structure stability and organic carbon distribution along the toposequence of Orumba North in derived savannah of the South-East, Nigeria

Chika Jidera*, Ezeokoye, C.S., Obalum, S.E., Ukaegbu, E. P

In high-rainfall zones with severe water erosion problems, soil structure stability as promoted by soil organic carbon (SOC) should be prioritized. Landscape positions and land use influence soil properties and nutrient distribution. This study assessed soil structure stability and SOC content at top-slope, mid-slope and low-slope positions of a toposequence at Orumba North in derived savannah zon...

Effects of Poultry Litter and the Residues of Maggot’s Production on Chemical Fertility of a Lixisol and Maize (zea Mays L.) Yield in Western of Burkina Faso

Kalifa Coulibaly*, Fernand Sankara, Salimata Pousga, Philippe J. Nacoulma, Marc B. Somé, Hassan B. Nacro

Organic substrates have shown their importance in the sustainable management of soil fertility and crops production. A study was conducted during 2 years (2016 and 2017) at western of Burkina Faso to evaluate the effects of poultry litter (PL) and the residues of maggots’ production (RMP) on soil chemical fertility and maize yield. The experimental design was a completely randomized block design w...

Use of erodibility indices in assessing soil erosion in central and northern Cross River State, Nigeria

Akpa E A*, Okon P O, Abam P O, Sunday L. K

Soil erodibility indices were used to assess erosion prone areas in central and northern Cross River State, Nigeria. Fourteen (14) composite soil samples were collected at a depth of 0-30 cm and analyzed using standard laboratory procedures. Results showed that the soils are coarse textured with high sand content dominated by textural class of loamy sand in both the central and northern. The vulne...
