such option is the unified use of inorganic fertilizer and farmyard manure. Not only the above reason but also due to a long-term imbalanced fertilization approach, a lack of other nutrients, particularly, potassium (K), sulfur (S), zinc (Zn), and boron (B), has begun to become clear ...
(right) 2D plot of EM vs. kT for the same regions. The NPS and the bright Loop I regions have the same kT~0.3 keV, whereas the cavity has a slightly lower kT and smaller EM because its emission is dominated by the underlying kT~0.2-keV Galactic halo gas. ...
