I want to do plant experimental studies of wheat. Prior to this, I have done soil elemental analysis of primary nutrient and organic carbon. In 1 gram of soil , they are as follows:
N = 0.007 %
P= 0.00024 %
K= 0.00002 %
Organic carbon = 0.0025%
Organic matter = 0.0043 %
pH = 6.5
Now, I want to compare that is this alright to start the experiments or they are nnutrient deficient soil? How to compare with recommended level of soil. Kindly help
I suppose there is no answer to your question. Every country has its own requirements to soils, based on the concentration of toxic components, bacteria and others. Talking about fertility, I think that there is no standards applied to this issue. We have what we have and, therefore, we should improve what we have. I will be wondered if I am no right. I am following this question!
You should search for information in specialized journals. E.g.:
J. Plant Nutr. Soil Sci. 2020, 183, 705–717 DOI: 10.1002/jpln.201900590 "Bioavailability of macro- and micro-nutrients chemically extracted in acidic soils for wheat"
