This study shows the effect of soil structure, soil texture and different types of nutrients on the growth of Ammi visnaga (L.) Lam, as well as the yield of the fruit crop and its content of the main active principals (ɣpyrones). The study was carried out in several localities in Two Arabian countries in North Africa; Egypt and Sudan. Egypt: at three localities:-1st at Mepaco Farm in Enshas El-...

Antimicrobial resistance (AMR) in humans is inter-linked with AMR in other populations, especially farm animals, and in the wider environment. The relatively few bacterial species that cause disease in humans, and are the targets of antibiotic treatment, constitute a tiny subset of the overall diversity of bacteria that includes the gut microbiota and vast numbers in the soil. However, resistan...

Water is a scarce commodity in desert regions; yet, most remote sensing experiments of soil moisture have been conducted in temperate areas. The ability to detect and reliably assess soil moisture in the arid environment has important implications both at the micro scale such as the individual farm and at the macro scale for climate modeling. A series of experiments utilizing an airborne scatte...

A method to establish two experimental corky ringspot disease (CRS) plots that had no prior CRS history is described. CRS is a serious disease of potato in the Pacific Northwest caused by tobacco rattle virus (TRV) and transmitted primarily by Paratrichodorus allius. 'Samsun NN' tobacco seedlings were inoculated with viruliferous P. allius in the greenhouse before they were transplanted into th...

BACKGROUND Soil is increasingly recognized as an important source in the transmission of Toxoplasma gondii (T. gondii). The aim of this study was to investigate the presence of T. gondii in the soil and to grasp the relationships between the contamination of soil and chicken infections. METHODS PCR method based on T. gondii-conserved gene internal transcribed spacer 1 (ITS-1) as target gene a...

Biodynamic farming practices show promise in mitigating some of the adverse effects of conventional agriculture on the environment. Biodynamic farming is like organic farming in that no synthetic chemical fertilizers and pesticides are used. Unlike organic farmers, biodynamic farmers add eight specific preparations (made from cow manure, silica, and various plants) to enhance soil quality and p...

Little information is available on the relationship between the spatial distribution of zoonotic parasites in soil and the pattern of hosts' faeces deposition at a local scale. In this study, the spatial distribution of soil contaminated by the parasite Toxoplasma gondii was investigated in relation to the distribution and use of the defecation sites of its definitive host, the domestic cat (Fe...

Knowledge of spatial variation of soil properties is important in precision farming and environmental modelling. Spatial distribution of water content at field capacity (FC) and permanent wilting point (PWP) at different zones of a farm governs the available water for plant growth. These two soil hydraulic parameters play key roles in crop selection for different blocks of a farm, and in schedu...

Two strategies of phytoextraction have been shown to have promise for practical soil remediation: domestication of natural hyperaccumulators and bioengineering plants with the genes that allow natural hyperaccumulators to achieve useful phytoextraction. Because different elements have different value, some can be phytomined for profit and others can be phytoremediated at lower cost than soil re...

Sustainable Agriculture satisfies human food and fiber needs, makes the most efficient use of on-farm resources and integrates natural biological cycles, enhances the quality of life for farmers and society as a whole, and sustains the economic viability of farm operations. A farm that is able to produce continuously, yet has negative effects on environmental quality elsewhere, does not support...
