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...

This experiment was conducted to determine the effects of nitrogen and phosphorus fertilizers on nutritive value of safflower forage and silage by in situ and in vitro methods. The safflower forage was harvested at flowering stage, chopped to 3-5 cm particles and then ensiled in the laboratory silos for 60 days. The experimental treatments included: 1. Unfertilized forage (control), 2. Phosphor...

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...

Nitrogen (N), phosphate (P), and potassium (K) are the three most important nutrients applied into agricultural soils, but impacts of their single or combined application on soil fungal community structure stability still open questions. Using qPCR Illumina Miseq sequencing, variation communities in response to long-term addition N, P, K fertilization alone combinations a Mollisol field was inv...

Abstract Application of different fertilizers to check the efficiency expression Bt (Bacillus thuringiensis) gene in one leading commercialized crops (cotton) against Lepidopteran species is great concern. The Cry protein level can be controlled by improvement nutrients levels. Therefore, myth response toxin combinations NP was explored three cotton cultivars. Combinations include levels nitrog...

Low level or no use of organic and inorganic fertilizers serious imbalances soil nutrients, depressed potato yields pose accelerated mining native nutrients. Present on-farm studies was undertaken to observe the combined effects FYM compost along with fertilizers, particularly NPSB on production. The experiment comprised seven treatments: No fertilizer, recommended NP (115 kg N 92 ha-1 P2O5), P...

The effects of chemical and organic fertilizers on saffron (Crocus sativus) were studied in a field experiment using a complete randomized block design with three replications at ferdowsi university of Mashhad. Fertilizers applied were N, P, K, NP, NK, PK, NPK, cow, sheep and chicken manure. The amount of chemical fertilizer applied were 50, 30, 30, 48, 48, 36, 66 kg/ha for N, P, K, NP, NK, PK,...

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...
