Because many reptiles oviposit in soil within agricultural landscapes, this study evaluated the toxicity of two commonly used nitrogenous fertilizers — urea and ammonium nitrate — to snapping turtle (Chelydra serpentina) egg survivorship. Eggs were incubated, unmanipulated and under ambient conditions, in a community garden plot treated with urea at realistic rates up to 200 kg/ha in 2004 and ammonium nitrate up to 2,000 kg/ha in 2005, and separately in covered laboratory bins designed to minimize nitrogen loss through volatilization or leaching. In the field, neither urea nor ammonium nitrate affected hatching success or development, despite ammonium nitrate showing overt toxicity to native plants. In the laboratory, however, both fertilizer exposures reduced hatching success, lowered body mass at hatching, and reduced post-hatching survival compared with controls. The authors attribute the field's lack of toxicity to leaching and atmospheric loss of nitrogen in soil, and conclude that nitrogenous fertilizers likely have little direct impact on turtle eggs deposited in agricultural landscapes.

This laboratory-scale study tested incorporating bauxite minerals — red waste from alumina refineries — into a specialized soil layer for rooftop gardens, aiming to address the release of pollutants in urban stormwater runoff, a known issue with green roofs, against a backdrop of declining green-planted surfaces in urban areas. Bauxite minerals were noted for their high trapping capacity for trace metals and other soluble species and ease of integration into rooftop garden systems. Based on equilibrium adsorption capacity, an optimum amount of bauxite minerals was proposed, and rainwater runoff characteristics and pollutant release were compared between standard and modified rooftop gardens at laboratory scale. The green roof system with the bauxite layer was found to reduce heavy metal concentrations, and the technique is suggested as applicable to other green surfaces in housing complexes.

Seven eco-villages in Germany, Denmark, and the UK were selected for field surveys of settlement background, social and economic aspects, architectural specifications, recycled energy, and landscape characteristics of external spaces, analyzing the landscape characteristics of community gardens and common spaces and the ecological symbolism of landscapes created by residents. The eco-village landscapes were found to intend neither a return to primitive society nor control of nature through technology but rather coexistence with nature, with primitive nature symbolically restored and residents who share this outlook intending to cultivate this common sense together, landscape creation playing an important role in establishing a shared relationship between human living and nature.

This theoretical study addresses the "rurban fringe," the transitional zone connecting city and countryside, discussing rural landscape ecological features and landscape functions before setting out the content of landscape ecological construction. It proposes six elements: (1) rural landscape planning based on landscape ecological principles aimed at protecting regional traditions; (2) seeking optimal patterns for coordinated development between city and countryside; (3) developing tourism agriculture and urban agriculture in place of low-efficiency agriculture; (4) developing local rural landscape resources to promote eco-rurban tourism; (5) green landscape construction; and (6) building landscape corridors and networks for biodiversity protection, concluding by identifying trends in rurban fringe development.

A survey of soil micro-arthropods was conducted at selected farm locations in Ogun State, Nigeria, including a university farm, a school garden, a farmland, and a rubber plantation. The study identified micro-arthropods from Class Arachnida (orders Acarina, suborders Oribatida, Actinedida, Gamasida) and Class Insecta (order Collembola). The rubber plantation had the highest population (x = 24.75), while the university farm had the least (x = 1.75, Oribatida only). Physico-chemical soil analysis indicated that soil properties and farm practices influenced micro-arthropod distribution.
