“…Under sugarcane monoculture, the four heavy metals in most soil samples had soil concentrations greater than the levels stipulated by the soil environmental quality standard regulations (Alloway, 1995;Abd El-Azeim et al, 2016;Tang et al, 2020) and critical values for plant growth (Linzon, 1978). This varied range of heavy metals content in soils under sugarcane monoculture is apparently related to soil texture and might be owing to metals deposited sediments in Nile floodplains and continuous addition of polluted irrigation water and artificial and organic fertilizers, which is in a good agreement with results by Abd El Azeim et al, (2016) and Tang et al, (2020).…”

“…(1) The single contamination coefficient or contamination factor, C i f = C sl i / C n i , where C i f is the contamination coefficient of a particular heavy metal, Csl i is the measured data of soil heavy metals, and Cn i is the reference value . In this study, the reference background values were used to accurately reflect the contamination levels at the alluvial soils in El-Minia Governorate, Egypt (Abd El-Azeim et al, 2016).…”

“…In Egypt, sources of the agricultural soil contamination involve the utilization of contaminated agrochemicals, irrigation with saline and polluted groundwater, the reuse of drainage water, the recycling of wastewater, the polluted air, and the inappropriate disposing of solid wastes (Abd El-Azeim et al, 2016). These various sources pose a great threat to the sustainable agricultural ecosystems and soil health (Abd El-Azeim et al, 2016;Cheruben et al, 2016;Haddad et al, 2019). Heavy metals have been identified to alter soil physical and chemical properties that affect the biological population, diversity, fertility, and soil health (Sahu and basti 2021).…”

Soils must receive maximum protection to assure sustainable agriculture and quality food production. Heavy metals tend to accumulate in the soil rather than decompose and at a certain limit of their content, toxic consequences for living organisms occur. This research was conducted to survey the contamination status of Cd, Cr, Ni, and Pb and microbial activity in soils affected by long-term sugarcane monoculture in Upper Egypt. The rise of diacetate fluorescein hydrolysis (FDA) ranged from 86.25 to 201.25 mg kg -1 soil•h -1 in sugarcane monoculture fields, while the increase under crop rotation fields showed higher and significant values ranged from 207.25 to 266.67 mg kg -1 soil•h -1 . In this study, generally soil microbial biomass and enzymatic activity was usually and significantly higher under crop rotation than sugarcane monoculture. The highest potential ecological risks were found in soils under long-term irrigated sugarcane monoculture, while being moderate for crop rotation. Under both sugarcane monoculture and crop rotation farming systems, cadmium Cd was observed to be the urgency pollutant with the highest degree of contamination even though Cd had the lowest average concentration (Cd 27.03 mg kg -1 ) in sugarcane monoculture fields, and Cd (10.46 mg kg -1 ) in crop rotation. In view of the impacts of these potentially toxic elements of cadmium (Cd), chromium (Cr), nickel (Ni) and lead (Pb), on the ecological system and public health, the introduction of new management practices in sugarcane monoculture fields are essential to protect the environment and to achieve future sustainability in sugarcane production in Upper Egypt.

“…Field experiment was conducted at the experimental farm facilities (28°18′16″N latitude and 30°34′38″E longitude), Faculty of Agriculture, Minya University, Egypt, in order to study the effects of different fertilization systems on biochemical and biological soil properties as sensitive indicators of soil health after monocropping cultivation of potato crop (Solanum tuberosum L.). Soil of the experimental site had a clay texture and classified as alluvial soil according to Abd El-Azeim et al (2016). Prior to the initiation of the field trial, clay soil detailed in Table 1 was collected, air dried, and sieved to < 2.0 mm, and composite sub-samples were used to determine the basic soil physicochemical properties using standard methods derived from Page et al (1982).…”

The aim of this study was to determine temporary impacts of different fertilization systems on some labile soil biochemical and biological properties following potato monocropping under arid conditions. Field and incubation experiments were conducted to determine specifically soil organic carbon (SOC); dissolved organic carbon (DOC); dissolved organic nitrogen (DON); microbial biomass C (C mic), N (N mic), P (P mic); bacterial and fungi counts; soil resistance index (SRI); net N mineralization (N min); and some enzyme activity. Levels of SOC; DOC; N min , C mic , P mic ; bacteria and fungi counts; and soil respiration (SR) were significantly increased under organic and integrated fertilization systems compared with inorganic nano or NPK fertilization system, while levels of microbial biomass N (N mic) and DON were markedly increased under nano or fertilizers compared to organic or integrated (organic + inorganic) fertilizers. By contrast, higher values of metabolic quotient (qCO 2) were recorded in nano or fertilizer treatments suggesting that microbial biomass was less efficient under high maintenance of soil carbon. Enzyme activities of dehydrogenase (DH), β-glucosidase (βG), and acid phosphatase (Ac-P) were in the order of organic > integrated > inorganic fertilization systems, while enzyme activity of urease (UR) was in the vice versa order. Integrated fertilization system recorded greater levels of SOC; DOC; N min , C mic , P mic ; and SR relative to inorganic fertilizers even though applied at lower rates. It is, therefore, important for soils under monocropping system to poise organic and inorganic fertilization system that enhances soil health and soil organic matter build-up.

“…The other 95% has sandy and calcareous soils, with coarse texture, low fertility, high infiltration rate and low organic matter (less than 0.5%). Reclamation of these soils making them more productive and habitable in order to solve the problems of food and housing for the continuously increasing population, is crucial for Egypt's future (Abd El-Azeim et al, 2016).…”

Application of organic in combinations with inorganic N fertilizers can supply plants with all necessary nutrients in slowly available forms without environmental pollution. Vegetable field trials were conducted under controlled greenhouse conditions for two successive seasons using radish as a catch crop in order to evaluate environmental hazards and agronomic benefits of applying different combinations of organic and inorganic N fertilizers to sandy soil. Over both seasons of this study, improvements in growth quality parameters of radish plants were in most cases not significantly different at the higher fertilizer application rates of 120 and 180 kg ha-1. This finding indicates that radish response as a catch crop owing to the increasing of fertilizer application rate is subjected to diminishing returns, beyond which further additions will not improve the yield but pollute soil environment.Results of this research showed that, major considerations in applying of inorganic N fertilizers alone on sandy soils monocropped with catch crops are the increase in residual nitrate in soils, the increase in groundwater contamination potentials by nitrate, and the threat of nitrates build-up in plant tissues. Under conditions of this study, high application rates of inorganic nitrogen fertilizer (180 kg ha-1) caused high levels of nitrate accumulation in radish, and on being consumed by human beings, pose serious health hazards. In general, at the rate of 120 kg ha-1 equal combined organic and inorganic fertilizers, no health problems could be foreseen to humans or animals from food chain movement of nitrates. From this research it could be concluded that incorporation of combined organic and inorganic fertilizers into sandy soil monocropped with catch crops at the rate of 120 kg ha-1 nitrogen using drip irrigation system was the best management strategy practice to reach optimum agronomic benefits while minimizing environmental and health hazards.
