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-...

Biorecovery of rare earth elements (REE) from wastes and ores is achieved by bacteria using biogenic phosphates. One approach uses an enzyme that biomineralises REE phosphate crystals into the extracellular polymeric matrix (EPM). The enzyme, co-localised in the EPM, provides a continuous phosphate feed into biomineralisation. The bacteria can be immobilised in a column, allowing continuous met...

broomrape would have irreversible effects on tomatoes in all growth stages and the damage would be unrecoverable. in order to chemically control orobanche spp with consumption of bio-fertilizer in tomato cultivation, an experiment as factorial based on complete randomized blocks design in three replications and 12 plots was carried out at a farm which is located in mahabad city (iran). in this ...

Water treatment alternatives such as adsorption using agricultural residues are currently being studied to eliminate pollutants that cause eutrophication in water bodies, avoiding the alteration of aquatic ecosystems. In this work, two bio-adsorbents were prepared cellulose extracted from corn stems, Zea mays, which labeled MC (quaternized modified with Cetyl trimethyl ammonium chloride) and B ...

Tomatoes (Solanum lycopersicum) plant were provided with bio-fertilizers issued from anaerobic digestion of olive mill wastewater without and 1%, 5% phosphate residues in mesophilic conditions for 25 days. 1% raw substrates (OMW raw; OMW + 1%PR 5%phosphate residues) digestates (olive digestate, 1%phosphate digestate digestate) was fortnightly to the plants. Reclaimed water a treatment located s...
