Agroforestry trends in Punjab, Pakistan

  Pakistan in general and the province of Punjab in particular have a narrow forest resource. More than 90% of the fuel wood and about 72% of timber requirements are being met from trees growing on the private farm lands, based on agro forestry / social forestry / community forestry as compared with the state forests. It is obvious that trees have to be grown in conjunction with agricultural crops on private...

Transfer and accumulation of lead, zinc, cadmium and copper in plants growing in abandoned mining-district area

The analysis of the Jebel Hallouf-Sidi Bouaouane mining-district soil has shown that the surface horizons are strongly contaminated by heavy metals, especially during floods or in lee-side areas. The contents of metallic-trace elements (MTE), in the soil and two cultivated plant species, have been determined by Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES). The results show that the concentration of...

Marginal effects of rural roads and irrigation canals on woody and non-woody species composition

  Across the northern rural regions of Iran, gardens and farmlands are being fragmented into smaller and smaller patches by rural roads network with significant edge effects on plant species composition and abundance. In this study, the presence of different plant species was recorded in ninety 11 m plots on nine 100 m transects at the edge of terrene rural roads with irrigation canal and without irrigation...

Determination of pesticide residues in blood samples of villagers involved in pesticide application at District Vehari (Punjab), Pakistan

  Blood samples were collected from field workers involved in pesticide spraying activities at three different farms in Tahsil Mailsi, District Vehari (Punjab), Pakistan. Twenty seven villagers (including three controls), ranging from 16 to 50 years of age and one to nine years of pesticide application experience were tested. The blood samples were analyzed for 383 different pesticides using Gas Chromatograph...

Impact of the insecticide endosulfan on growth of the African giant snail Achatina achatina (L.)

The impact of the insecticide endosulfan was assessed on the growth of the African giant snails, litter-living animals found in cocoa fields throughout tropical Africa. Two doses of endosulfan, C1, 6.25 a.i g/l and C2, 12.50 a.i g/l were applied twice with one month of interval to the litter of the snails. After quarantine, snails were allowed to feed on this litter and the elongation of their shells as well as their...

Physico-chemical properties and heavy metal content of water sources in Ife North Local Government Area of Osun State, Nigeria

  The water quality examination in Ife–North Local Government of Osun State Nigeria was conducted by determining the physico–chemical parameters of 40 samples. Surface water, bore holes, wells and pipe borne water samples were collected from major towns in the Local Government Area and analyzed. Results showed temperature range of 26.5 to 33.0°C, pH (6.53 to 8.90), conductivity (63.0 to...

Geochemistry and mineralogy of Ogun phosphate rock

  Suitability of direct application of phosphate rock as low cost phosphorus fertilizer for crop production must be environmentally safe. Four pellets of Ogun phosphorites labeled OG1, OG2, OG3 and OG4 were randomly selected and subjected to petrographic, X-ray diffraction and X- ray fluorescence analyses. Petrographic results revealed two textural forms: nodular (OG1 and OG3) and granular (OG2 and OG4)....

An improved technique for the prediction of optimal image resolution(s) for large-scale mapping of savannah ecosystems

  Past studies to predict optimal image resolution required for generating spatial information for savannah ecosystems have yielded different outcomes, hence providing a knowledge gap that was investigated in the present study. The postulation, for the present study, was that by graphically solving two simultaneous equations of values of image noise index (INI) and degradation level Index (LDI), a robust...
