This study was carried out to evaluate the fertility status of soils in Ahiazu Mbaise, Imo State under three land use types using nutrient index method and fertility rating. Soil samples were collected from five sampling points each from three land use types at the depth of 0 20 cm. Samples were prepared and analysed for physical properties such as particle size distribution, bulk density, mois...

This study was conducted to evaluate soil fertility status in the eight major agro ecosystems viz., coconut, banana, rubber, paddy, arecanut, nutmeg, pepper and vegetables in Thrissur District, Kerala. For this, a total of 30 panchayats out of 92 were selected representing 6 agro ecological zones in the district. Surface soil samples (0-15 cm) @ one sample/ ha. were collected from dominant agro...

The field of soil fertility deals mainly with the mineral nutrition of plants in which both the supplying power of the soil and the ability of the plant to absorb nutrients, are of importance. The soil may be considered as. the rooting medium which provides water and mineral nutrients necessary for plant growth. Ionic equilibria play a fundamental role in fertility relationships because they go...

Soil sampling for the purpose of fertility assessment is normally confined to the plough layer with little or no attention to the rooting pattern of the crop in question or the availability of subsoil nutrients. However, there is little doubt that a thorough understanding of the development and activity of plant roots in their soil environment is essential to a balanced soil fertility research ...

Bringing together emerging lessons from biophysical and social sciences as well as newly available data, we take stock of what can be learned about the relationship among subjective (reported) and objective (measured) soil fertility and farmer input use in east Africa. We identify the correlates of Kenyan and Tanzanian maize farmers’ reported perceptions of soil fertility and assess the extent ...

In this article we investigate if qualitative soil fertility datasets derived during participatory processes can be combined with a corresponding land use change model (i) to improve the understanding of the socialecological complexity of land use change and (ii) to allow testing of alternative scenarios even in datapoor environments. To test this hypothesis, a participatory assessment approach...

Distillery sludge application in degraded soils is amongst the most important economical resources for the soil fertility amelioration through improvement in soil water-holding capacity, texture, structure, nutrients retention, roots penetration, and reduction in soil acidity [1-3]. Presently due to the ever increasing number of sugar mills and distillery units in the country, it is now become ...

Restoration of polycyclic aromatic hydrocarbon- (PAH-) polluted sites is presently a major challenge in agroforestry. Consequently, microorganisms with PAH-degradation ability and soil fertility improvement attributes are sought after in order to achieve sustainable remediation of polluted sites. This study isolated PAH-degrading bacteria from enriched cultures of spent automobile engine-oil po...
