The initial effectiveness of two rock phosphate samples from Morocco (MRP) and North Carolina (NCRP) was compared with concentrated superhposphate (CSP) in greenhouse using two Alfisols and one Ultisol from southern Nigeria. Under similar pH condition (pH 6), the two rock phosphates were more ef...

Presents results of economic analysis carried out in southwestern Nigeria to determine the profitability of alternative land use systems, taking into account the short and long-run impact of soil erosion on agricultural productivity. The fallow systems include 1. two continuous cultivation alley ...

The potential of alley cropping maize and cowpea with the giant Leucaena (Leucaena leucocephala (Lam) de Wit) cultivar K-28 was studied on an Entisol (Psammentic Ustorthent) in Southern Nigeria. In this trial the crops were grown in 4 m wide alleys formed by periodically pruned leucaena hedgerows...

Evaluation of soil aggregate stability under managed fallow systems is very relevant in the assessment of their agricultural sustainability. It is also important to identify the parameters that are most responsive to the effects of these fallow systems on aggregate stability. This study was carri...

Effects of hedgerow species on surface soil physical properties were studied in an on-going trial established since 1981 on an Oxic Paleustalf in southwestern Nigeria. The experimental treatments were Leucaena leucocephala, Gliricidia sepium, Alchornea cordifolia and Acioa barterii hedgerows plan...

Alley farming involves the cultivation of food crops among hedgerows of multipurpose trees. Use of woody legumes provides N-rich mulch and green manure to maintain soil fertility and enhance crop production, and protein-rich fodder for livestock. The success of alley farming depends on a number o...

A simplified Shaw's wet‐combustion technique for carbon (C) determination in plant materials is described which requires less reagent and operation time. The simplified technique gave high recovery (99.4%) of the C in analytical pure grade sucrose and citric acid, and high reproducibility of C me...
