Aim
The current study aimed to assess the potential of foliar‐applied zinc oxide nanoparticles (nZnO) in improving wheat growth and mitigating the zinc (Zn) deficiency stress that is increased by the negative interaction between Zn and phosphorus (P) under saline–sodic soil conditions.
Methods
A wire house trial was conducted to produce Zn‐enriche...
Excessive use of nitrogenous (N) fertilizers for intensified cropping has negative environmental impacts, including the emissions of nitrous oxide (N2O) and ammonia (NH3), as well as nitrate (NO3-) leaching, however, enhanced efficiency nitrogenous fertilizers (EENFs) could be an innovative and most effective option for minimizing N losses.This stu...
Environmental degradation, especially soil deterioration, is a well-known issue that must be addressed in the changing climatic and economic scenario. It is the need of time to restore natural resources while maintaining a balance between increasing food demand and use of natural resources. Agricultural soils are the primary source of food producti...
PurposeHeavy metal contamination, i.e., cadmium (Cd) via phosphate-based fertilizers is of great concern globally due to the potential risks for human and environmental health. The present study was done to use Brassica campestris (a hyperaccumulator plant) to assess the different phosphate-based fertilizers for their Cd contamination vulnerability...
Accumulation of heavy metals in the environment can pose a potential risk to living organisms. Ingestion of leafy vegetables, containing heavy metals, is one of the main routes through which these elements enter the human body. The present study was conducted to assess the accumulation of lead (Pb) and zinc (Zn) in spinach grown on metal contaminat...
Contamination of soil and water with potentially toxic elements (PTEs) has become a global environmental concern which could pose potential risks to human health and agriculture. The major anthropogenic sources of PTEs contamination include coal combustion processes, leather tanning operations, mining and smelting activities and use of sewage water...
Cadmium (Cd) is a highly soil mobile heavy metal which is toxic even at very low concentrations and is thus of potential human health concern due to its entry into the food chain via consumption of edible crops. The plant nutrition is the most economical and practicable method among all strategies for reducing the accumulation of Cd in the edible p...

I have to apply the biochar @ 1% on Carbon Equivalent Basis in the soil and want to get my calculation checked by the experts and need suggestions.
The biochar has 72 % OC.
72 g of OC is present in = 100 g of Biochar
1 g of OC is present in = 100/72
= 1.39 g of biochar
SO for adding biochar @ 1% on Carbon Equivalent Basis
100 g of soil need biochar = 1.39 g of biochar
1 g of soil need biochar = 1.39/100
1000 g/1kg soil need biochar = (1.39/100) ×1000
= 13.9 g biochar/kg of soil
Please check whether the calculation is correct or not.
I have applied N in the soil @ 250 mg kg-1 in 100 gram of soil. After that I have taken the samples in the glass vials having rubber septum and analyzed on GC-ECD. I have got the results which are in 10-6 V/V. I need Nitrous Oxide emission from soil. Total soil used is 100 g and area of head space above soil (in glass Jar) is 0.0094 m2. @Dieter Lohr

I have applied 250 mg kg-1 N in 100 g of soil in an incubation study. Plz help in calculation the amount of Ammonia emission...
I need the latest figure of Nitrogen losses in the environment as %.
I have the figure that upto 50 % of N nitrogen taken up by the plant, N2O losses are 14-15%, Ammonia losses are 5-50% while 15-40% is the leaching loss. Plz comment
I am going to start the Lysimeter Experiment in which I shall grow rice crop and measure the losses of Ammonia (Boric Acid Trapping) and Nitrous Oxide (taking N2O sample by Syringes) from close chamber.
Literature shows that there is no issue of NH3 and N2O measurement from same chamber as there is no reaction of Boric Acid (used for trapping Ammonia) with N2O. Need expert guidance??
Secondly while using chambers for measuring Ammonia Losses from rice crop, I shall place the chamber in the lysimeter in such a way that rice plant is enclosed in the chamber for 2 hrs as losses are also from roots. I am going to use transparent chamber as there is no issue of light during sampling period for the plants. Needs further experts opinions related to the chamber used in rice crops?
I have to add Biochar in 42 kg of soil taken in lysimeter. the rate of biochar is @ 1% on C equivalent basis. Need help in the calculation of Biochar needed in each lysimeter
