abstract low water holding capacity of soilless substrates increases water stress and waste of nutrient solution. irrigation time management can reduce such problems. in this research, responses of hydroponically cultured greenhouse strawberries were evaluated under different irrigation schedules. in first step, plant daily water need was estimated and then delivered to plants through two metho...

degraded soils in northwest china are mostly nonproductive due to imbalanced nutrient and inadequate water supply. the effects of manure application at three different rates (7.5, 15.0, and 22.5 t ha–1) combined with chemical fertilizers on soil water and water-use efficiency in maize [compared with chemical fertilizers (control)], under semi-arid conditions in dark loessial soil and over a per...

Superior productivity of genotypes in forest plantations depends on the supply, capture and use-efficiency resources. In this context, knowledge regarding nutritional efficiency Eucalyptus influences farmers researchers decision-making management ecosystems. The aim research was to estimate nutrient-use planted state Rio Grande do Sul, Brazil. We evaluated six potential at 43-month-old stands. ...

Abstract Introduction Nitrogen is a key nutrient for plants. Often less than 50% of the applied nitrogen fertilisers acquired by crops and can be easily lost into environment causing environmental pollution. Thus, to make agriculture more sustainable, it important investigate which factors determine use efficiency (NUE). We investigated whether NUE was higher in organically managed soils compar...

Elliott, K.J. and White, AS., 1993. Effects of competition from young northern hardwoods on red pine seedling growth, nutrient use efficiency, and leaf morphology. For. Ecol. Manage., 57. 233255. The effects of competition from three northern hardwood tree species on red pine (Pinus resinosa Ait. ) seedlings were examined on two clear-cut sites in western Maine. We examined how planted red pine...
