Impact of Land Use/cover on Carbon Sequestration in Afaka Forest Reserve, Northern Guinea Savanna of Nigerian

Ibrahim Abdulwahab Jimoh*, Sulaiman Yau Lawan, Odunze Azubuike Chidowe, Sawa, B.A,

This study aims to assess the impact of land use/cover on carbon sequestration in Afaka Forest Reserve. Six (6) land use/cover types were delineated and used in the study area. This includes Eucalyptus plantation (EP), Farmland (FL), Gme- lina plantation (GP), Mixed plantation (MP), Natural plantation (NP) and Teak plantation (TP). A profile pit was dug in the middle of each of the delineated land...

Improving the Physical Properties of a Degraded Alfisol in Nigeria Using Organic Amendments for Profitable Okra Production

Oshunsanya S.O.*

Experiments were conducted between 2007 and 2008 to determine the optimum rate of organic fertilizer (OF) for okra production and to evaluate residual effects of OF on soil physical properties. Six different rates of OF; 0 kg N ha-1 , 60 kg N ha-1 , 80 kg N ha-1 , 100 kg N ha-1 , 120 kg N ha-1 and 140 kg N ha-1 were replicated five times in a Randomized Complete Block Design on an Alfisol in the s...

Soil Organic Carbon Fractions and Aggregation of a Tropical Alfisol as Affected by Plant Residues

ADESODUN Johnson Kayode*, Udom B. E., Abudu O. S., Adejuyigbe C. O.,, Enikuomehin O. A, Thannia B. M, Oke O. O., Olowokere F. A., Oyegoke, C.O,, Mbila M.

Incorporation of plant residues into soil plays a vital role in enhancing the quality of fragile tropical soils. This study evaluated the short-term effect of plant residues of different quality on organic carbon (OC) fractions, carbon management indices and stability of a sandy loam soil with low (< 2%) initial OC content. The residues are Banana clippings (BC), Chromolaena odorata (CO), Leucaena...

Organic Manuring on Fruits and Vegetable Production and Soil Properties in Landmark University, Omu - Aran, South - West Nigeria

Agbede O. O.*, Fabiyi E.F., Adeleye, M.B.,, Nwafor S.I., Adekiya, A.O

Three experiments were established in the field within Landmark University Teaching and Research Farm during 2013 and 2014 cropping seasons (August – November each year). One experiment tested the response of tomatoes to Urea (at 40 kg/ha rate), NPK (40 kg/ha), Cowdung (5t/ha) and Poultry manure + NPK. The second trial tested the effect of varying levels of poultry manure + NPK. The second trial t...

Maximum Phosphate Adsorption Capacity as Influenced by Some Biochar Properties

Abdu N*, Solomon Rejoice Ibrahim, Ado Adamu Yusuf, Bello M.

The use of biochar as a low-cost adsorbent to remove nutrients from aqueous solutions is getting great attention lately due to its many environmental applica- tions and benefits. Although biochar has been widely used to remove phosphate from aqueous solutions, inconsistencies still exist with regards to biochar proper- ties responsible for the adsorption process. This research was therefore, carri...

Effect of Different Rates and Types of Fertilizers on Growth of Improved Coconut (cocos Nucifera)seedlings

AONDONA O.*, Ilori E.G., AWANLEMHEN B.E., UDOH M., OKONJO P.N

Comparative effects of different rates of inorganic and organic fertilizers on the performance of improved coconut palms (hybrid and dwarf cultivars) were evaluated using coconut seedlings planted in 15kg soils in polythene bags at screen house of NIFOR main station, Benin City, Edo State. The reference fertilizer used was NPK Mg 12:12:17:2 and was applied at rate 0, 28, 42, 56 and 72g/pot (this w...
