Abstract Ammonium nitrate is a hygroscopic and caking product for growing agricultural products. In order to improve the properties of ammonium nitrate, composition calcined crushed cathode material from used lithium ion battery was studied. Since mainly consists lithium, cobalt, manganese nickel, it has been adopted as polymicroelement-containing additive nitrate. Studies have shown that intro...

Biobased nitrogen (N) fertilizers derived from animal manure can substitute synthetic mineral N fertilizer and contribute to more sustainable agriculture. Practitioners need obtain a reliable estimation of the biobased fertilizers’ value. This study compared estimates for pig slurry (PS) liquid fraction digestate (LFD) using laboratory incubation plant-growing experiments. A no-N treatment was ...

KAYMAK, H. C., 2013. Effect of nitrogen forms on growth, yield and nitrate accumulation of cultivated purslane (portulaca oleracea l.). Bulg. J. Agric. Sci., 19: 444-449 The present investigation was carried out to determine not only the most appropriate nitrogen form but also the effect of these forms on growth, yield, element content and nitrate accumulation of cultivated purslane (portulaca ...

Efficient plant-growth-promoting rhizobacteria (PGPR) used as biofertilizers and biological control agents are promising substitutes for minimizing the application of synthetic agrochemicals in crop production. We studied effect PGPR strain Bacillus velezensis BS89 alone combination with three forms nitrogen fertilizers (ammonium nitrate, carbamide, ammonium sulfate) on productivity two strawbe...

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...

nterest in organic fertilizers is growing in the greenhouse industry, but experience and trials are not keeping up. There is little information available on how well the new types of fertilizers provide nutrition for plants compared to traditional water-soluble chemical fertilizers. The most widely available “organic” fertilizers for application like traditional water-soluble fertilizers are fi...

Agrotechnical assessment of struvite produced by a lab-scale sedimentation unit is performed. As source phosphates and ammonia, liquor obtained through dewatering ?unicipal wastewater treatment plant sludge was in use. The range ammonia the 130 - 250 380 560 mg/L, respectively. Seawater brine with magnesium concentration around 60 g Mg2+/L applied as magnesium. agrotechnical characteristics wer...
