Quantitative nitrate leaching relationship models based on nitrogen fertilisation and the intervals between maize irrigations in the salt-affected soil

Journal of King Saud University - Science, Journal Year: 2024, Volume and Issue: 36(5), P. 103187 - 103187

Published: March 29, 2024

Nitrate leaching from soil is a major environmental issue in modern agriculture as it can contaminate groundwater and degrade quality. Both nitrogen fertilization practices irrigation methods contribute greatly to increased nitrate leaching. Researchers have developed quantitative models predict based on these farming techniques. This article examines new literature focusing such models, particularly regarding salty soils used for maize cultivation. The study investigated the effects of application rates intervals properties clay Egypt. Results showed that frequency significantly impacted water table depth, salt content, moisture levels, availability, levels. Correlations were discovered between application, schedules, various parameters. research emphasizes managing timings maximize while minimizing during production. Proper agricultural management techniques are needed reduce pollution risks. review contributes more sustainable practices.

The destruction of the Roman cities Pompeii and Herculaneum during eruption Mount Vesuvius in 79 AD serves as a well-documented example first humanitarian disaster linked to an environmental event. Most buildings two many its inhabitants were buried under volcanic ashes within 48 hours rest by further eruptions. Both remained hidden until their accidental rediscovery 18th century. While dramatic devastating, events like eruptions, earthquakes, tsunamis are naturally occurring there is no evidence that last millennium even largest eruptions affected global climate.1 In contrast, Anthropocene era describes period when human activities have been dominant influence on climate ecosystems (www.nationalgeographic.org). Climate change sceptics point fact urbanisation, industrialisation associated not new: for example, construction Ancient Rome caused widespread deforestation soil erosion around Mediterranean which may contributed fall Empire (www.smithsonianmag.com). However, or other natural disasters, these tended be local temporary. By stark over century particular agriculture burning fossil fuels energy, led rapid increase carbon dioxide (CO2) atmosphere rise world temperatures.2 2022, UN data showed 40% all land now classified degraded intense farming3 limiting only ability feed world's population, but also recycling CO2. fossils fuel accompanied emissions air pollutants such nitrogen oxides (NOx), sulphur (SO2), ozone (O3) particulate matter (PM). Over three decades, mounting epidemiologic outdoor pollution increases respiratory diseases including lung cancer, cardiovascular disease, cognitive decline dementia (www.gov.uk/government/publications/air-pollution).4 Long-term exposure ambient with lower cancer survival4 has worse Covid-19 outcomes pandemic.5 A recent study indicated rising antibiotic resistance across every country continent.6 Overall, mortality attributable PM increased from 3.5 million 1990 4.2 2015 was fifth-ranking risk factor world.7 2020, European Union (EU), 96% urban population exposed levels above health-based guideline level set World Health Organization (WHO) resulting 238 000 premature deaths (www.eea.europa.eu/publications/air-quality-in-europe-2020-report).
