A study was conducted to assess the status of available zinc in soil of Teaching and Research Farm, Modibbo Adama University, Yola North East, Nigeria. Ten soil samples were collected from 0 – 20 and 20 – 50 cm depths to reflect the soil of the study area. The soils were analysed following standard laboratory procedures. Result obtained showed that the soils were sandy loam to sandy clay loam, slightly acidic (mean = 6.4 – surface; 6.5 – subsurface soils), very low OC content (mean = 0.35 % – surface; 0.27 % – subsurface soils), low to medium Total N and exchangeable bases.

Abstract:

We designed two NGSS-aligned middle school classroom experiments to investigate the effects of biochar on plant growth and soil respiration. Biochar is a carbon-rich material, produced by heating organic matter under limited oxygen, that is added to soils to improve fertility, to promote plant growth, and as one possible strategy to help mitigate climate change. The experiments offer an ideal case study for students learning fundamentals of soil and plant interactions. Soils and biochar are accessible, are connected to global issues such as agriculture and climate change, and are the focus of

In addition, the soil of the region is characterized by low organic matter content because of annual bush burnings, which reduce the low humus content of soils.

Abstract:

Challenges facing humanity over the years include food insecurity, loss of soil and water resources and associated ecosystem disturbance. The rate of hungry people in developing world keeps on increasing and causing death and malnutrition. Food shortages, food insecurity or undernourishment has assumed a global dimension especially as climate change hits the globe with its negative impacts, with more severe cases recorded in the poor-resource African countries. Soil is the natural capital which drives the agricultural sector, being a strong-hole for crop/animal farming, apart-from being a medi

Abstract:

<p>Soils of the southern Guinea savanna zone of Nigeria are inherently infertile due to shortened fallow period and the continuous use of inorganic fertilizer which depletes the soil of micronutrients such as zinc over time. A field trial was carried out at the Teaching and Research Farm of the University of Ilorin, Nigeria during the 2016 and 2017 cropping seasons to evaluate the effect of zinc and NPK fertilizer on the growth, yield and zinc concentration of seeds of sesame. The experiment was laid out as a factorial fitted into a randomized complete block design (RCBD), replicated thr

Abstract:

Production of agricultural wastes is increasing while soils are progressively losing organic matter due to intensive cultivation and climatic conditions. This makes the recycling of organic wastes a useful alternative to incineration, landfill or rubbish dumps. The effects of two agro- wastes and mineral fertilizer on growth and yield of leaf amaranth were assessed in a pot experiment at the Teaching and Research Farm, Ekiti State University, Ado-Ekiti. Treatments consisted of poultry manure (PM) and palm oil mill effluent (POME) each applied at 8 and 16MT/ha while NPK 15-15-15 was applied at

The decrease in the cost of sensors during the last years, and the arrival of the 5th generation of mobile technology will greatly benefit Internet of Things (IoT) innovation. Accordingly, the use of IoT in new agronomic practices might be a vital part for improving soil quality, optimising water usage, or improving the environment. Nonetheless, the implementation of IoT systems to foster environmental awareness in educational settings is still unexplored. This work addresses the educational need to train students on how to design complex sensor-based IoT ecosystems. Hence, a Project-Based-Lea

Some qualities are inherent in it. I will teach you to make colors, colors are made from leaves, flowers, chemical scenes, many castes and colored soils, but the artist has to find the color of his choice.

It is not unreasonable to state that, even before the introduction of organic agriculture, African local farmers have numerous of undocumented environment-friendly, nature-inclined indigenous techniques for boosting soil fertility and enhancing crop yield. However, despite the versatility of indigenous knowledge, setback is always experienced from western science, which tags such knowledge as being non-scientific and not worthy of scholarly engagements.

Abstract:

Under intensive cropping systems in the tropics, application of chemical fertilizers becomes an apparently indispensable means of replenishing the rapidly depleting soil nutrients. However, the reported side effects of continuous application of synthetic fertilizers on soil and man are now a major concern. Hence, determination of the potentials of some easily exploitable natural or organic-based fertilizer material(s), which can effectively compete with the commonly used synthetic fertilizers like NPK 15-15-15, is a worthwhile scientific approach, not towards improved performance of versatile

Abstract:

Catholic economics is the interdisciplinary pursuit of joining Church teaching with economic science. The Church and its leaders, the Pope and Bishops, are primarily concerned with the salvation of souls and their general welfare, or the common good, and as such govern and guide the faithful to that end. Catholic scholars seeking to apply those teachings are free to and do debate the merits of particular policies or institutions. Catholic economists also question particular economic theories that contrast with Church teaching, especially with regard to human nature. This article examines these

Abstract:

We report the results of a study into the interaction between floodwaters and an unconfined alluvial aquifer in the Chowilla anabranch system of the River Murray during a large flood. Data on watertable elevation, groundwater chemistry and unsaturated zone salt storage were collected before, during and after a flood in 1990 which inundated all but the very highest points of the floodplain. These data, combined with analytical modelling of the watertable behaviour throughout the flood, led us to conclude that diffuse vertical recharge of floodwater to the unsaturated zone is of little importanc
