Arthropods can be either large or too small to be seen from the microscope. Their legs are jointed and perform a specific function in the soil. Several arthropods have been identified to date. Therefore, it is essential to identify them in a different type of soil. An experiment to quantify the soil arthropods in the urban forests of D.G. Khan was conducted at the Zoology lab of Ghazi University on four tree plants, i.e., neem (Azadirachta indica), mango (Mangifera indica), guava (Psidium guajava), and phalsa (Grewia asiatica). Soil samples were taken from different areas and on different months. The diversity of arthropods was analyzed through the Shannon index. The results were all significant. The total number of arthropods found in the experiment was 5151, with the following distributions: millipedes were 132 in neem, 133 in guava, 113 in mango, and 121 in phalsa; centipedes were 136 in neem, 142 in guava, 118 in mango, and 132 in phalsa; springtails were 138 in neem, 130 in guava, 120 in mango, and 134 in phalsa. There were a total of 12 different species of arthropods found. Neem (Azadirachta indica) have mites, centipede, and ants; guava (Psidium guajava) have centipedes and ants. Mango (Mangifera indica) have millipedes, centipedes, mites, springtail, and ants, and phalsa (Grewia asiatica) have mites, ants, and centipedes. The study reveals that millipedes, centipedes, springtails, and ants were found abundantly in the urban forest area of D.G. Khan, resulting in increased organic matter decomposition and appropriate distribution of nutrients through the soil having beneficial effects on the terrestrial ecosystem.

A field trial was conducted at the Research Farms of Michael Okpara University of Agriculture, Umudike, South Eastern Nigeria to assess the potential of leaves, seeds, barks and roots of Azadirachta indica and Moringa oleifera in the control of bacterial spot and fruit rot diseases of watermelon (Citrullus lanatus), in a Randomized Complete Block Design (RCBD) experiment. Results obtained showed that all the plants parts assessed reduced disease incidence and severity drastically at 5% probability when compared with the control. Extracts of A. indica seed had the best performance at 12 weeks after planting on vine length (140cm), number of branches (8.00), number of leaves (49.00), and number of fruits (16.00) and compared favourably with synthetic pestic ide (streptomycin) on fruit weight at harvest (4.96kg) and in reducing incidence of the bacterial spot (61.27%) and fruit rot (35.51%) as well as severity of the spots (2.64) and rot (3.33) (P=0.05). From t he results obtained it means that the extracts of A. indica and M. oleifera could serve as a safe and che ap alternative to synthetic pesticides in the management of leaf spot and fruit rot of watermelon.

The Neem tree, the oil of which has a long history of pesticide, fertilizer and medicinal use in India, has been studied extensively for its organic compounds. Here we present a physical, mineralogical and geochemical database resulting from the analyses of two Neem soil profiles (epipedons) in India. Neem tree derivatives are used in the manufacture of a variety of products, from anti‐bacterial drugs and insecticides to fertilizers and animal feeds. A preliminary geochemical and mineralogical analysis of Neem soils is made to explore the potential for chemical links between Neem tree derivatives and soils. Physical soil characteristics, including colour, texture and clay mineralogy, suggest the two pedons formed under different hydrological regimes, and hence, are products of different leaching environments, one well‐drained site, the other poorly drained. Geochemically, the two Neem soils exhibit similarities, with elevated concentrations of Th and rare earth elements. These elements are of interest because of their association with phosphates, especially monazite and apatite, and the potential link to fertilizer derivatives. Higher concentrations of trace elements in the soils may be linked to nutritional derivatives and to cell growth in the Neem tree.
