Several process-based models exist for the assessment of soil, water and air nutrient dynamics. These models have been developed after several years of continuous monitoring, testing, and re-validation. Two of the most widely used models, the CENTURY 4.0 and the RothC models have been used extensively. Modelling helps to understand the principal mechanisms affecting ecosystem functioning, and the causes of disturbances to them. They are essential for long term predictions and in making recommendations aimed at reducing harmful effects and preventing environmental disturbances. Many authors...

Modelling helps to understand the principal mechanisms affecting ecosystem functioning, and the causes of disturbances to them. They are essential for long term predictions and in making recommendations aimed at reducing harmful effects and preventing environmental disturbances (Ifremer, 2005).Many authors have demonstrated the benefits of using computer models in agriculture (Farage et al., 2005; Paul et al., 2003; Webb et al., 2003; Pumpanen et al., 2003; Qian et al. 2003; Parton, 1996; Smith et al., 1996, 1997). Although mechanistic soil-crop models are increasingly accepted as valuable...

This book shows that microbial diversity and the environment are continuums of interrelated concepts where the emergence of novel entities and relationships are defined by selection and adaptation at the molecular level. The potency of molecular creativity is embedded in the structure and function of nucleic acids, but protein molecules that have the capacity to sense and respond to environmental change and ecological stimuli mediate its actualization. In turn, fatty acids and other structural molecules accomplish the ecological sustainable strategies for organism survival and competition....

Life is a journey. The way time flies. Three decades of academics, research and charity packed life. From 1984 - 2014 the pedestal has been on to shape tropical agriculture, capture temperate agriculture, and serve humanity in all spheres of life. Most rewarding is the metamorphosis in academics and charity at local and cross-country levels. There can be no better tribute to my lecturers, supervisors, students, bosses, schools, colleges and universities than to chronicle this personal three decades of experimentation in tropical Nigeria. The place of experimentation in tropical agriculture...

The origin of England and English language is better done by historians. However, England is a one of the country in United Kingdom. The remaining countries that make up United Kingdom is Scotland, Wales and Northern Ireland. It is a small but mighty kingdom that traverse all nooks and corners of the world in colonial past, present and the future. In view of the fact that all nations of the world that have ever had direct or indirect English touch behaves similar to the English men, including forgetting their mother tongue which the English people have refused to forget. The home base of the...

In today's era of extensive literature review based on other scientists findings and acknowledgements and replication of researches in diverse environment and conditions; and coupled with the era of researching and publishing just for peer review and journal publication fun; it has become increasingly difficult to break-through the norms of discovering novel ideas and facts attributed to super scientists. Even though developed world have not abandoned the due process and procedure of documenting their experts, including the challenging Noble Prizes in different fields of endeavour, which...
