What type of soil does Nigeria have?
What type of soil does Nigeria have?
The major soil types in Nigeria, according to FAO soil taxonomy legends are fluvisols, regosols, gleysols, acrisols, ferrasols, alisols, lixisols, cambisols, luvisols, nitosols, arenosols and vertisols. These soil types vary in their potential for agricultural use.
What is the distribution of soil?
The soil types are represented in a variety of soil maps at different scales from 1:25 000 scale, where the predominant mapping unit is the soil series to 1:250 000 scale where the mapping units are much more complex and heterogeneous .
Where can sandy soil be found in Nigeria?
Northern zone – sandy soils This sandy soil is mostly found in Sokoto, Kano, Kaduna. Its lightness and looseness are well suited for planting crops.
Is Nigeria fertile soil?
According to FAO (2001), Nigeria is one of the countries with high declining soil fertility.
Does Nigeria have good soil?
The soil quality in Nigeria is rated low to medium quality for growing crops. The Food and Agricultural Organization (FAO) concluded that much of the land is medium quality if managed and maintained properly. Nigeria has 84 million hectares (Nigeria’s total is about 91 million hectares) that are able to be farmed.
What is the distribution of black soil?
Black soils are derivatives of trap lava and are spread mostly across interior Gujarat, Maharashtra, Karnataka, and Madhya Pradesh on the Deccan lava plateau and the Malwa Plateau, where there is both moderate rainfall and underlying basaltic rock.
What is the distribution of alluvial soil?
Alluvial soil is distributed widely in the Northern Plains of India, also in eastern coastal plains in India such as Mahanadi delta, Godavari delta, Krishna delta and Kaveri delta.
Where can I get clay soil in Nigeria?
Clay deposits occur in Abak, Akwa Ibom State, Uruove near Ughelli in Delta State, Ifon in Ondo State, Mokola in Oyo State, Sokoto in Sokoto State, Gombe in Gombe State, Dangara in Niger State, Umuahia in Abia State, Onitsha in Anambra State e.t.c. Almost every State in Nigeria has at least one known deposit of kaolin.
What are the distribution of crops in Nigeria?

| Characteristic | Share of farming households grwoing crop |
|---|---|
| Maize | 49.7% |
| Cassava | 46.2% |
| Guinea corn | 29.6% |
| Yam | 25.8% |
Which state in Nigeria has the most fertile soil?
Mambila Plateau (Taraba State) is also the only place that has the weather required for temperate vegetable crops to grow. It is the most fertile land for growing crops.
What is the average farm size in Nigeria?
0.5 hectares
Nigeria’s small family farmers own 0.5 hectares of land on average, predominantly managing mixed crop-livestock systems, including also fish farming.
Is there a 30 m resolution soil information system for Africa?
In this paper we describe production of a 30 m resolution Soil Information System of the African continent using, to date, the most comprehensive compilation of soil samples ( \\ (N \\approx 150,000\\)) and Earth Observation data.
Are there any soil property and class maps for Africa?
Until recently, soil property and class maps for the continent of Africa were only available at very generalised scales 7, 8, 9, with many countries not mapped at all. Considerable soil resources of Africa, especially organic matter 10 and nutrient stocks 11 remained largely unmapped and unknown.
How are predictions of soil properties and classes generated?
Predictions of soil properties and classes are generated by (1) training the learners i.e. fitting the spatial prediction models, then (2) applying these fitted models to all pixels so that a complete and consistent map can be produced 1, 5.
What is a predictive soil map (PSM)?
Predictive Soil Mapping (PSM) aims to produce the most accurate and most objective predictions of soil variables either for bulk estimates or for specific soil depths. PSM, a sub-field of Applied Predictive Modeling 1, can be considered to be an interdisciplinary field incorporating statistics, soil science and Machine Learning 2, 3, 4, 5.
