The idea of eliminating the use of fertilizers which are sometimes environmentally unsafe is slowly becoming a reality because of the emergence of microorganisms that can serve the same purpose or even do better. Depletion of soil nutrients through leaching into the waterways and causing contamination are some of the negative effects of these chemical fertilizers that prompted the need for suit...

Israel is a small country with a total land area of 21,000 km, from which 20% is arable land. More than half of Israel has an arid to semi-arid climate. Approximately half of the cultivated area (200,000 hectares) has to be irrigated due to lack of rainfall and other water resources. Approximately 80% of the irrigated land in Israel uses the fertigation method, combining the application of wate...

The experiment was carried out to study the relationship between soil calcium conditions and content of this element in fruit leaves apple trees at ground fertilization with nitrogen potassium. experimental orchard is located forest-steppe zone Central Russian Upland (Oryol region). Loamy haplic luvisol a slightly acidic reaction high organic matter. Fruit plantations are represented by ‘Sinap ...

Long-term application of fertilizers containing P, especially organic fertilizers, usually increases the water soluble and available P of soil and at the same time may result in P accumulation in soil. Organic fertilizers may also increase movement of P in the soil profile that could result in surface and ground water pollution. An experiment was conducted on field plots that received three app...

Taraxacum kok-saghyz (TKS) is a promising natural rubber plant. In the current study we investigated effects of nitrogen, phosphorus, and potassium base fertilizers on growth yield TKS through field experiments. We found that appropriate application can significantly increase root, total sugar TKS. The enhanced when amount nitrogen increased accordingly to 107.2, 10.5 35.3 g m–2. Maximum accumu...

Phosphorus (P) is one of the most important elements required for crop production. The ideal soil pH its absorption by plants about 6.5, but in alkaline and acidic soils, consumed P forms an insoluble complex with calcium, iron, aluminum availability plant decreases. supply needed mainly achieved through chemical fertilizers; however, addition to high price these fertilizers, long run, their de...

Agricultural applications of chemical fertilizers are a world wide practice. The specific activity of uranium-238 and heavy metals in phosphate fertilizers depends on the phosphate ore from which the fertilizer produced and on the chemical processing of the ore. Composite phosphate fertilizers samples where collected and the uranium-238 specific activity, in Bq/kg, and As, Cd, Cu, Pb, Se concen...

Sulfur is an essential nutrient—along with nitrogen, phosphorus, and potassium—for plant growth development. mostly supplied to crops through soil fertilizers. However, chemical fertilizers are overused increase crop yields despite environmental threats. The proper use of positively affects yield increase. Regardless, residues from misuse threaten not only the ecosystem, but also marine ecosyst...
