Phosphorus is one of the key factors that regulate soil fertility. Its deficiencies in soil are largely replenished by chemical fertilizers. The present study was aimed to isolate efficient phosphate solubilizing fungal strains from Eisenia fetida vermicompost. Out of total 30 fungal strains the most efficient phosphate solubilizing one was Emericella (Aspergillus) nidulans V1 (MTCC 11044), ide...

Trace metals occur naturally in rocks and soils, but increasingly higher quantities of metals are being released into the environment by anthropogenic activities. Metals are chemically very reactive in the environment, which results in their mobility and bioavailability to living organisms. People can be exposed to high levels of toxic metals by breathing air, drinking water, or eating food tha...

In the present study, the amount of nitrate and phosphate leaching from agricultural lands into the Zanjanrood River in Iran was simulated using the Soil & Water Assessment Tool (SWAT) model. The measured average monthly discharges at the Sarcham station were used to calibrate and validate the SWAT model, and the SWAT Calibration and Uncertainty Program (SWAT-CUP) model was applied to perform t...

Commercial cultivation of blueberry has rapidly expanded in China recent years. However, suboptimal fertilization results poor growth and management practices orchards. The present study studied southern highbush southwest China. We evaluated the effects inorganic nitrogen, phosphorus, potassium fertilizers at different doses. Plant vegetative growth, leaf photosynthesis parameters, fruit quali...

Non-nutritive metals, especially cadmium (Cd), are present in P fertilizers; the long-term application of these fertilizers leads to Cd build-up soil. The current study aims evaluate impacts sources and rates on growth maize (Zea mays L.) bioavailability Cd. Twelve treatments including rock phosphate 4 g kg−1 (RP1); 8 (RP2); 12 (RP3)); single super 333 mg (SSP1); 444 (SSP2); 555 (SSP3); di-ammo...

Phosphorus (P) recovery from dairy wastewater involves its accumulation into phosphorus-rich sludge using a physico-chemical or biological process. The high iron content in chemical decreases usability agricultural activities. hydrothermal carbonization (HTC) is an option used to treat the obtain hydrochar for various applications, including use as energy source and carbon-dense material. HTC p...

Soil fertility improvement is an important area which needs attention since most of the hazardous inputs added into the agricultural system are in the form of chemicals. Since crop production and soil normal flora are affected by input of chemical fertilizer. Biofertilizer microorganisms make the nutrients available to plants. The present study was concerning to isolate of some Pseudomonas fluo...

this research set out to evaluate the effect of combined biological and chemical nitrogen fertilizers on some corn hybrids. to this end an experiment was conducted as split plot on the basis of randomized complete block design with four replications. main plots were included: use of chemical and biological fertilizers in four levels: 100% chemical fertilizer, 75% chemical fertilizer + 100% bio-...

Phosphate rock, raw material used to produce fertilizers, due its composition can be a source of metals, radionuclides and other traces. The application phosphate fertilizers redistribute increase the concentrations both metals in soiland water profiles, influencing their availability subsequent transfer food chain. Knowing proportion this is essential implications it have on human animal healt...
