Abstract Increasing rates of nitrogen (N) conventional fertilizer have led to increasing risks N losses the atmosphere, mainly as ammonia (NH 3 ) and nitrous oxide (N 2 O). The aim this study was evaluate effect foliar N-based nanoformulations on dynamics O NH emissions from grasslands. Six treatments (50 kg ha −1 plus a control ( n = 4) were tested completely randomized design: granular urea (...

Nitrogen is one of the most important factor affecting maize (Zea mays L.) yield and income of smallholders under semiarid climates. Field experiments were conducted to investigate the impact of different N-fertilizer sources [urea, calcium ammonium nitrate (CAN), and ammonium sulfate (AS)] and rates (50, 100, 150, and 200 kg ha-1) on umber of rows ear-1 (NOR ear-1), number of seeds row-1 (NOS ...

Phosphorus (P) is an essential nutrient for crops. Modern agriculture dependent on P derived from phosphate rock, which a non-renewable resource that becoming increasingly scarce and expensive. Therefore, it necessary to identify alternative sources of develop novel technologies its recovery. Such are focused the recovery struvite (MgNH4PO4·6H2O) (STR) urban wastewater. A reduction in effluents...

An experiment was conducted to find out the effect of INM on vegetative growth, flowering and fruiting of Andrographis paniculata. The experiment was followed in a randomized block design with 8 treatments. The different treatments were T1no treatment, T2vermicompost, T3-biofertilizers, T4-chemical fertilizers, T5biofertilizers + vermicompost, T6biofertilizers + chemical fertilizers, T7chemical...

This study was conducted to evaluate the effect of liming (CaCO3 1000 kg ha−1) and application organic fertilizers (rotted farmyard manure 40 t six different combination mineral fertilizers: NPK 15:15:15 800 ha−1 + KAN (calcium ammonium nitrate) 240 ha−1; 400 MCB (water-soluble fertilizer 13:11:20 2MgO microelements humic acid) 300 125 KMg Multi 13:0:43 2MgO) 100 600 on yield other productivity...

Aims: Synthesis and characterization of carbon-based nitrogen fertilizer assess the releasing pattern newly synthesized N fertilizer.
 Study Design: The experiment was laid out in Completely Randomized Design (CRD) with seven treatments three replications.
 Place Duration Study: incubation study conducted Soils Environment post-graduate laboratory at Agriculture College Research Insti...

Microbial biomass nitrogen and carbon were studied in long-term field experiments with continuous cultivation of silage maize and with crop rotation. a positive effect of organic fertilizers on the microbial biomass nitrogen and the carbon content in soil was observed. Statistically significant effect of organic fertilizers on the higher content of microbial biomass C and n was established in t...

Ammonia (NH3) volatilized from cropland significantly impacts the ecological environment and human health. The identification quantification of atmospheric sources NH3 are therefore important for emission reduction air pollution control. Choosing appropriate nitrogen (N) fertilizer types is one key ways to reduce emissions agricultural systems due different N fertilizers with factors. natural a...
