: A study was carried out in Orogun main town in Ughelli North local government area of Delta state of Nigeria to determine the best locations for dumpsite and borehole for potable water supply. This was achieved by using the Global Positioning System (GPS) and the meter tape. The longitudes, latitudes and elevations of sixteen locations evenly distributed within Orogun main town were measured and recorded with the aid of the Global positioning system. Using the meter tape, the depths to water levels in the hand dug wells at the same locations were also measured. The water elevation contour map of Orogun town revealed that ground water flow direction is towards the North-Western part of the region. In the event of pollution, boreholes within the North-Western part of Orogun main town are prone to contamination. This is because any contaminant in the South, East, West and North-Eastern part of Orogun migrates and settles in the North-Western regions. Hence, dumpsites could be sited in the North-Western part while boreholes for potable water could be sited within the South, East and North Eastern part of Orogun main town in other to minimize groundwater contamination and hence avoid water borne diseases. The present study acts as a guide for the location of dumpsites and future exploration and exploitation of groundwater to avoid water borne diseases.

Human beings are in economic conflict with soil biodiversity for a life struggle. The need for increased food production to match the demand for the ever increasing human population in Uganda, has led to agriculture intensification. This however is associated with a high level of ecological disturbance by poor methods of farming that upset the balance of soil biodiversity especially in Wakisi and Nagojje Sub Counties. A study of 60 households in Wakisi and Nagojje to determine factors affecting adoption of soil biodiversity conservation measures revealed that education and household size (number of active adults in the household) were statistically significant for the adoption rate. Results of the logistic regression model showed that education predisposes farmers to new knowledge and therefore enhances their potential to their adoption while big households are good indicators of labour supply which is vital in labour intensive technologies. Researchers therefore recommended that farmers should be educated using practical methods to increase literacy about technologies, government should provide incentives to farmers and support organizations that have shown interest in the technologies and that, farmers should always be involved in the technology right from the development stage in order to capture their perceptions about new technologies.

Zinc adsorption at concentrations between 0 to 50 m g Zn l -1 was evaluated in surface and subsurface samples of a basaltic soil in the North ern Guinea Savanna, a Rhodic khandiustult. After adsorption, 3 consecutive extractions (desorp ti n) in sequence were performed to the samples by using 25ml of 0.1NHCl. The results showe d that the Ap and Bt horizons have large capacities to adsorb zinc. While the desorption sho wed that the sorbed zinc was not rigidly bound. The amount of zinc released in the Ap horizo n was slightly more than that released in the Bt horizon, i.e. Zn was more difficult to relea s in the Bt horizon than in the Ap horizon. The adsorption data did not fit the linear form of either the Langmuir or the Freundlich isotherms .The amount of Zn needed to be added to g ive a critical level of 1.0 mg kg -1 was estimated to be 20 mg kg -1 of Zn and above in the Ap horizon. Whereas it was estimated to be 40 mg kg -1 and above for the Bt2 horizon.The examined soil co uld ffer an effective way to increase or decrease zinc ions concentration.
在北几内亚稀树草原(Rhodic khandiustult)的玄武岩土壤表面和地下样品中，评估了浓度在0至50 m g Zn 1 -1之间的锌吸附。吸附后，用25ml 0.1NHCl对样品依次进行3次连续萃取(解吸)。结果表明，Ap层和Bt层对锌具有较大的吸附能力。而解吸表明，吸附后的锌没有刚性结合。锌在Ap层的释放量略大于Bt层的释放量，即Zn在Bt层比在Ap层更难释放。吸附数据既不符合Langmuir等温线，也不符合Freundlich等温线的线性形式。为了达到1.0 mg kg -1的临界水平，需要添加的Zn量估计为20 mg kg -1及以上。而据估计，Bt2水平为40毫克千克-1及以上。研究结果为提高或降低锌离子浓度提供了有效途径。
