Is the difference of 2℃ in soil temperature is enough to make a significant difference in nutrients uptake and mineralization?
what is the optimum soil temperature for nutrient mineralization and uptake for temperate fruit crops like blueberry?
Yes, its a huge temperature difference , we observed thsi in citrus grown in central India. During anthesis in Nagpur mandarin , we observed a rise of 20C temeprature compared to preceding 20 years and we could melow it by adding an addition 20% of K through RDF . Such obervations necessitated the revisiting of RDF for any crop , instead of RDF to be considered as one time exercise.....
Soil temperature between 2℃-38℃ increases the organic matter decomposition31 by increasing the movement of soluble substrates in the soil https://medcraveonline.com/APAR/effects-of-soil-temperature-on-some-soil-properties-and-plant-growth.html
