How can formulate Phosphorus 52 and Potassium 34 in liquid ?

how to find the accuracy levels of pesticide , fertilizers with different datasets . kindly help me with this.

I have an inquiry regarding nitrogen nutrition in sugarcane, and I trust that experts in nutrition and sugarcane research may provide insights.

Many sources indicate a positive correlation between the moisture content of sugarcane sheaths and the percentage of nitrogen in the leaves. However, I have not observed any significant positive or negative impact of foliar nitrogen on pod moisture levels.

In one of my experimental designs concerning sugarcane nutrition, I recorded multiple measurements, and the treatment with elevated leaf nitrogen concentration exhibited increased pod moisture.

If my findings are accurate, what supporting evidence do you possess regarding this matter?

Furthermore, can the beneficial influence of nitrogen on root development and enhanced water absorption be considered a valid rationale?

It is important to note that all environmental conditions, soil types, and irrigation methods were consistent across both treatments, with the sole variable being the quantity of nitrogen fertilizer applied.

I am kindly looking for an incubation experiment protocol on measuring the sorption capacity of carbon dioxide by biochar when a known amount of carbon dioxide is inserted and gas samples withdrawn at specific time intervals then measured with gas chromatography

In my research, I aim to analyze the volatile organic compounds of shallots. During sample preparation, I should use liquid nitrogen before GCMS SPME injection. In the last sample, I used more nitrogen (in several samples before I used 2 small cups of nitrogen, and in the last sample I used 3 small cups of nitrogen). So, is there any possibility that liquid nitrogen can suppress the production of volatile organic compounds? Because just the last sample provided a different chromatogram result.

Thank you.

I have adult zebrafish that were snap-frozen with liquid nitrogen.

In our experiment, we are required to apply 3 different treatments of C:N ratio i.e. 15:1, 20:1, and 25:1. If there is any specific formula that we're unaware of we'd appreciate your input.

how is the process in analyzing Carbon in soil?
