Values of organic materials as fertilizers to northern Nigerian crop production systems
Organic materials, the combined products of different animal and plant sources, play vital roles in agricultural crop production systems. They are more environmental friendly than inorganic fertilizers and added many values to soil and crop production, economically. They sustain and restore soil inherent properties, enhance soil biological activities and potentially increase crop yields, which are safe for human...

Impact of deforestation and subsequent cultivation on soil fertility in Komto, Western Ethiopia
The study examined the impact of deforestation and subsequent cultivation on soil fertility and acidity conditions under varying soil depths. Soil profiles were opened in two adjacent land units, namely forestland and arable land and samples were collected from genetic horizons. Deterioration of soil fertility was observed after deforestation and traditional cultivation. The main aim of deforestation was agricultural...

Influence of different leguminous crop on the ultisol that had been continuously cropped to cassava /maize for over six years
Leguminous crops play an important role in developing sustainable and low input crop production system and have shown good potential for inclusion in alley cropping systems. Hence, a study was carried out at the Teaching and Research Farm of the Faculty of Agriculture, Chukwuemeka Odumegwu Ojukwu University to evaluate the productivity of an impaired ultisol under cassava/maize for over six years planted with different...

Assessment of sedimentation in Tuli – Makwe Dam using remotely sensed data
A remote sensing approach was used to assess sedimentation in Tuli-Makwe Dam in the semi-arid Mzingwane Catchment in the Matebeleland South province of Zimbabwe. The loss in reservoir gross capacity due to sediment deposition for a period of 47 years since the construction of the dam in 1966 to 2013 was determined to be 3.371 Mm3 which translate to 40.84 % gross capacity loss. The revised capacity of the dam is...
