In silviculture, mineral fertilization is necessary to supply the nutritional demand, however, recommendation of quantities be applied should aim at maintaining productive capacity soil. The purpose this study test whether increasing recommended fertilizer dose improves soil fertility and increases productivity Eucalyptus dunnii in sites central region Pampa biome, Brazil. doses 150 g (T0), 225...

Understanding the physiological processes associated with high yield traits in modern cropvarieties is essential to further increase grain yield and improve nutrient management strategies.Field trials were conducted to study the effects of fertilization and variety on the grain yield ofrice (Oryza sativa L.) with two fertilizer levels and 18 modern varieties. The objectives were toevaluate yiel...

Abstract Pelites (shales and mudstones) are arguably the most important rock type for interpreting metamorphism. Their significance derives from their widespread occurrence range of mineral assemblages they develop at different conditions pressure temperature. We compiled a global database 5729 major-element whole-rock analyses pelites metamorphic grades to granulite-facies paragneisses) (1) de...

two types of mineralization including porphyry copper and epithermal gold mineralization have occurred in relation with an intermediate volcano-plutonic complex in masjeddaghi area. different alterations including silica, advanced argillic, intermediate argillic and propylitic have been distinguished in relation with epithermal mineralization, which have a zonal pattern. elemental mass gains an...
