Compost is commonly utilized to improve properties of infertile sandy soils, despite its high biodegradability which may increase greenhouse gases emissions. It is possible to combine compost with biochar, which degrades at a slower rate, forming a “co-composted biochar” product. This mixture could enhance plant growth parameters beyond those attai...

Iteractions among phosphorus (P) and micronutrients may greatly influence plant growth and soil productivity. Thus, a greenhouse investigation of a complete randomized design was conducted to highlight such interactions in which a clayey soil (enriched with either 5 mg Fe kg-1 soil , 1mg Mn kg-1 soil ,or 1.5 mg Zn kg-1 soil) received P in the form...

In the late 1950s, residents of a Japanese fishing village known as “Minamata” began falling ill and dying at an alarming rate. The Japanese authorities stated that methyl-mercury-rich seafood and shellfish caused the sickness. Burning fossil fuels represent ≈52.7% of Hg emissions. The majorities of mercury’s compounds are volatile and thus travel...

The present work aimed at using GIS spatial analysis tools to map soil quality (SQ) of the cultivated lands for sustainable agricultural development. The study covers an area of about 2306.43 km2 in the north Nile Delta of Egypt (31°08' 38" to 31° 36' 15.53" N and 31°01' 16.67" to 31° 54' 40.37" E). Thirty-two surface soil samples (0 – 30 cm) were...

PHOSPHATE IONS are hard-Lewis-bases, , which might not preferably bind with Fe, Mn and Zn (borderline Lewis acids); though P-applications diminish considerably availability of micronutrients and other elements such as selenium. Interactions between P and these elements are still in need for more detailed investigations. Therefore, the current study...

Elevated levels of potentially toxic elements (PTEs) in soil possess a potential threat to human health. Probably, the use of hyper-accumulator plants can be an eco-friendly and cheap approach to attain more desirable levels of these contaminants in soil. The current study is a trial to increase the efficiency of basil (hyperaccumulator) plants to...

The wheat plant was previously cultivated on a salty soil treated with biochar and/or sprayed with K, either in its regular form or the nano one, with nanoparticles of Si and organic fertilizer dominated by amino acids in this experiment. Soil samples collected after harvesting wheat were utilized in this experiment to examine the effects of the af...

The study aimed at evaluating so...

Sustainable management of low fertile arid soils using carbon-rich organic amendments such as biochar and compost is of great concern from both agricultural and environmental points of view. The impact of pyrolysis, composting, and co-composting processes of different feedstocks on carbon loss and emissions, soil properties, and plant growth in ari...

Organic amendments are important sources of nutrients that release upon organic matter degradation, yet the stability of these organics in arid and semi-arid regions is relatively low. In contrast, humic substances (HS) are resistant to biodegradation and can keep nutrients in the soil available for the plant over a long time. Combinations between...

Faba bean productivity is highly influenced by N-inputs; yet, mineral N-fertilizers might undergo rapid leaching in light textured soils. On the other hand, these mineral fertilizers are more preferable than organic N-sources to raise protein content in bean seeds. Thus, the current study investigates to what extent organic fertilizers can partiall...

Zinc is an important nutrient for maize growth and productivity; yet, its availability in many soils seemed to be low. Appling Zn as soil fertilizers might not be the optimum solution to satisfy plant needs for this nutrient because Zn precipitates in presence of phosphate fertilizers. Alternatively, deficit of this nutrient may be amended through...

In arid and semi-arid soils, organic residues undergo rapid degradation and their consequences are positive on both soils and living biota. Probably, humic substances, which are organics that resist biodegradation, can bring further positive consequences on soil characteristics and biota living therein on the short run. To investigate this hypothes...

Water scarcity in Egypt leads to using all water resources, including reusing treated wastewater.

Using low quality water for irrigation is probably one of the main reasons for contaminating the arable lands with potentially toxic elements (PTEs), especially within the arid and semiarid regions. On the other hand, most farmers depend therein on natural inefficient drainage systems to get rid of excess water flows. It was thought that the hydrau...

Radioactive cesium (Cs) is more likely to be trans-located via rainfall into surrounding environments.
