Ebook "Fundamentals of soil science (8th edition)" revision of a bestselling text shows that soil is three-dimensional and dynamic. This concept is developed in the first two chapters and is built on throughout the book. Chapters 3 through 7 explore soil physical properties and water, with expanded coverage of tillage and traffic and an increased emphasis on water and wind erosion processes. Chapters 8 through 11 discuss the biological aspects of soils as well as their mineralogical and chemical properties.

A survey was conducted in Tamil Nadu and Maharashtra to isolate the actinomycetes from the soil samples for study. Twenty seven cultures of actinomycetes were isolated, purified and designated as actinomycetes (A1 to A27). The test cultures A1 to A27 were taken for studying their acaridical activity. Preliminary screening revealed that five of the isolates were active against spider mite, Tetranychus urticae on okra. Out of the sixteen isolates A7 and A27 isolate showed highest activity against red spider mite, Tetranychus urticae.

The open sunny patches of the forest of upper Assam had been tremendously infested by the noxious alien vine Mikania micrantha and might be the prime factor for forest conversion. Present study was carried out in Bherjan-Borajan-Podumoni Wild Life Sanctuary situated in Tinsukia district of Assam. Extensive field surveys were conducted during the period 2014-2018 for evaluation of changes of microenvironment component viz. soil nutrient status, soil temperature, light interception and biomass production due to infestation of M. micrantha.

A survey was conducted in Kodaikanal hills of Tamil Nadu, India to know the association of root-knot nemtode, Meloidogyne hapla in carrot (Daucus carota subsp. sativus). The nematode was found in eight carrot growing villages surveyed at Kodaikanal. Infestation was high (150-300 nematodes/200 cm3 soil) at Poomparai followed by moderate (50-150 nematodes/200 cm3 soil) at Poondi, Kookal, Mannavanur and Shenbananur villages.
