AbstractLoss of phosphorus from agricultural land through water runoff causes serious detrimental effects on the environment and on water quality. Phosphorous runoff from excessive use of fertilizers can cause algal blooms to grow in nearby water systems, producing toxins that contaminate drinking water sources and recreational water. In this study, a risk analysis of the algal toxin micro-cystin-LR and the mitigation of phosphorus from agriculture runoff is discussed. A risk analysis was performed on the algal bloom toxin microcystin-LR considering the Lake Erie algal bloom event of 2011 as a

Phosphorus is an essential component of modern agriculture. Long-term land application of phosphorous-enriched fertilizers and animal manure leads to phosphorus accumulation in soil that may become susceptible to mobilization via erosion, surface runoff and subsurface leaching. Globally, highly water-soluble phosphorus fertilizers used in agriculture have contributed to eutrophication and hypoxia in surface waters. This paper provides an overview of the literature relevant to the advances in phosphorous management strategies and surface water quality problems in the U.S. Over the past several

Soil test phosphorus (P) concentration has a major influence on the dissolved P concentration in runoff from agricultural soils. Thus, trends in soil test P partly determine the development of pollution potential of agricultural activities. We reviewed the changes of soil test P and P balances in Finnish agriculture, and assessed the current setting of P loss potential after two Agri-Environmental Programs. Phosphorus balance of the Finnish agriculture has decreased from +35 kg ha1 of the 1980s to about +8 kg P ha1 today. As a consequence, the 50-yr upward trend in soil test P concentration

Agriculture accounts for 9 per cent of the total surface area of Finland and generates the greatest single nutrient input to Finnish watercourses. Since agricultural activity is scattered throughout the whole country its effects in lakes are less pronounced than those of domestic and industrial effluents. On the other hand, point source phosphorus loading of lakes and rivers decreased significantly during the nineteen-seventies. Phosphorus is the nutrient which primarily limits production in most Finnish lakes. The availability of phosphorus in agricultural runoff waters is therefore a crucial

Agriculture is often responsible for the eutrophication of surface waters due to the loss of phosphorus—a normally limiting nutrient in freshwater ecosystems.

The reduction of excess phosphorus loads from agricultural catchments prior to reaching downstream surface waters is therefore necessary.

Summary Phosphorus is an essential nutrient for all forms of life, which means that food cannot be produced without it. As the phosphate rock (concentrated source of phosphorus) is a non-renewable and finite resource, with no substitute, without more sustainable management of phosphorus its deposits could be depleted in a rather short period. In addition, much of phosphorus eventually ends up in environment, where it causes pollution. Hence, one could say that the lack of phosphorus and its inappropriate management could be a bottleneck for a sustainable food supply and agricultural developmen

Observed real-time parameters were soil pH, Electric conductivity, temperature, Nitrogen, Phosphorous, Potassium, and humidity. Soil sensor, multifunctional converter, solar panel, 4G WIFI, and cloud platform (USRIOT) were used. The result shows that nitrogen, potassium, phosphorus, pH, and Electric conductivity have a p

Phosphorus is a potential environmental pollutant, which could lead to the eutrophication of water bodies. For this reason, wastewater treatment plants worldwide are often designed and operated to eliminate phosphorous from effluents, at substantial cost. At the same time, phosphorus is an essential nutrient for agriculture and, consequently, human life. Data seem to suggest that the world will run out of phosphorus by around 2300, in the best case scenario, although even shorter estimates exist. This situation evokes the need for more efficient phosphorus recovery technologies, in order to me

Modern agriculture demands precise management of soil nutrition to optimize crop yield and minimize resource wastage. This presents a smart agriculture solution that utilizes an NPK sensor to monitor and regulate the levels of essential nutrients - Nitrogen (N), Phosphorus (P), and Potassium (K) in soil. The system is designed to automatically adjust nutrient levels when they fall below optimal values. Integrating NPK sensors in agriculture soil nutrition management represents a significant advancement in precision farming. These sensors are designed to detect the levels of the essential nutri

AbstractPhosphorus (P) is an important nutrient for all plant growth and it has become a critical and often imbalanced element in modern agriculture. A proper crop fertilization is crucial for production, farmer profits, and also for ensuring sustainable agriculture. The European Commission has published the Farm to Fork (F2F) Strategy in May 2020, in which the reduction of the use of fertilizers by at least 20% is among one of the main objectives. Therefore, it is important to look for the optimal use of P in order to reduce its pollution effects but also ensure future agricultural production

Pollution of groundwater, wetlands, rivers, estuaries and near shore waters by phosphorus is now fairly common due to run-off from agricultural areas and wastewater discharges. In the application of fertilisers in agriculture it has been observed that sandy soils result in high phosphorus concentrations in the run-off. On the other hand loamy soils result in less phosphorus run-off. Phosphate-phosphorus sorption by soils has been observed to be time dependent. A model has been developed to describe the movement of phosphorus through soils to take into account the processes of convection, dispe

Substance flow analysis was used to analyze phosphorus (P) flows, accumulations and losses in Lithuania. P and phosphate rock are included in the list of EU critical raw materials, showing their importance for the EU economy, especially agriculture, and supply risks. It is important to minimize P losses as much as possible, avoid inefficient use, and maximize the potential of secondary P. The analysis showed Lithuania’s huge dependence on P imports, which occurred because one of the largest P fertilizer factories operates in the country, and the country also grows and exports a significant amo

Phosphorus is one of the most important elements for life and growth of plants, animals and humans. Its absence or depletion from the soil necessitates their addition in the form of fertilizers. The only realistic source of elemental phosphorus and phosphoric fertilizers on commercial scale is phosphate rock. The importance of phosphate rocks becomes greater by taking into account that phosphorus can’t be obtained by recycling processes as well as that there are no substitutes for it in agriculture. In most cases, phosphate deposits have to be processed in order to meet the commercial requirem
