Son yıllarda çevre kirliliğini önlemek ve atıkları değerlendirmek amacıyla bitkisel üretim sonucunda elde edilen atıklar ile hammaddesi tarımsal ürün olan fabrikasyon atıklarının üretimde toprak düzenleyicisi olarak kullanılması yaygınlaşmıştır. Biyokömür, dünya genelinde bir bilinmektedir. Bu özelliği yanı sıra toprakta zengin karbon kaynağı olmasından dolayı da kullanılmaya başlanmıştır. Çalı...

BACKGROUND AND AIMS This study examined the physiological basis of the cost of reproduction in the epiphytic bromeliad Werauhia sanguinolenta, growing in situ in a tropical lowland forest in Panama. METHODS Entire mature plants were sampled repeatedly over the course of 2 years, which represents the common interval between reproductive events. Due to the uncertainty concerning the appropriate...

Research Associate, Department of Biological Sciences, University of California, Santa Barbara, California, 93109. Abstract: Productivity and nutrient cycling parameters were measured in mature stands of chaparral and coastal sage scrub in the Santa Monica Mountains, California, USA. Net annual production and the magnitude of annual nutrient transfers were much greater in the evergreen chaparra...

Nutrient recycling occurs when nutrients are released into the environment by animals or microbial consumers. Fishmediated nutrient recycling is an important source of nutrients for primary producers in many aquatic ecosystems, sometimes even exceeding external loading rates (Attayde and Hansson 2001). Consumers release non-assimilated nutrients as liquid waste that is available to primary prod...

Abstract This study evaluated the concentrations and distributions of nutrient non-nutrient elements in water, sediment, mud, vegetation Ologe Lagoon, Lagos, Nigeria. Nutrient including Na, Ca, K, Mg were found high concentration values different components freshwater ecosystem. While water had least elements, Trapa natans highest. Aluminium showed similar distribution patterns components, exce...

BACKGROUND: Nutrient management is one of the most important factors that affect the growth and production of maize. OBJECTIVES: Current research was conducted to investigate the effect of Mycorrhizas and vermicompost on seed yield, its components and quantities traits such as concentration of protein, starch, zinc, potassium and nitrogen of corn seed.<br...

Concentrations of 22 elements in pinewood were compared with that in frass produced by insects representing the following taxa: Reticulitermes spp. (Rhinotermitidae), Zootermopsis nevadensis (Termopsidae), Incisitermes snyderi (Kalotermitidae), Hylotrupes spp. (Cerambycidae), Heterobostrychus spp. (Bostrichidae), Lyctus spp. (Bostrichidae), and representatives of the family Ptinidae (formerly A...
