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...

Due to the high cost and low accuracy of high-temperature tests, viscosity data for multicomponent slag systems is difficult be obtained precisely. Therefore, it important fulfill database via reasonable methods with lower costs. In this study, a prediction method based on machine learning was proposed CaO-SiO2-FeO-Al2O3-P2O5 quinary system. To provide valid model, predicted by molecular dynami...

Investigations on the viscosity behavior of gasification slags with special respect to P2O5 are scarce. Therefore, a meta study was performed compiling relevant knowledge its effect melt compositions similar slags. The data showed whether oxide behaves acidic and as network former how changes varying basicity single-phase melt. A supplementary since previous paper anomaly bearing slag that is i...

A field investigation was conducted at Agronomy research farm A. S. (P.G) College, Lakhaoti, Bulandshahr during rabi seasons of 2006 and 2007. The treatments consisted combination four cropping systems viz. chickpea sole (M1), linseed (M2), chickpea+ 2:1 ratio (M3) pigeonpea + 4:2 (M4) in main plots; two irrigations vegetative stages (30-40 days) flowering stage (70-75 (S1) one irrigation (S2) ...

In calcareous soil, the growth and production of _Triticum aestivu_m depends on availability phosphates, which in turn reduces uptake nitrogen form urea, causes volatilization partial leaching both fertilizers, contributing to greenhouse effect, warming global. An alternative ecological solution for _T. aestivum _is inoculate _Pseudomonas putida _and_ Rhizophagus irregularis_ with endophytes th...

Rice is one of the food crops and commercial crops. also has potential to contribute significantly increasing income employment in rural areas. As indicated by rice imports from Thailand Vietnam, national production not been able meet domestic demand. The objectives this study were (1) determine actual land suitability levels plants Luwu Regency (2) find out limiting factors for Regency. Evalua...
