The Balance of Some Macro and Micro Fertilizers, The Effect on Nutrient Availability, Chlorophyll, Protein and Its Correlation with Yield Index of Rice in Inceptisols

Yüzüncü Yıl Üniversitesi Tarim Bilimleri Dergisi
Rice productivity is highly dependent on optimal soil nutrient availability. A balanced combination of macro and micro fertilizers is expected to improve soil nutrient balance and enhance plant nutrient uptake.

Nutrient uptake by leaf

, 2013
Foliar fertilization is an effective practice to correct nutritional deficiencies in plants that are under stress conditions or in soils with low nutrient availability, and consists in applying nutrient solutions directly on leaves. Nutrient absorption in the leaf occurs mainly through the epidermis, by diffusion, due to the nutrient concentration ...

The biogeochemical influence of nitrate, dissolved oxygen, and dissolved organic carbon on stream nitrate uptake [PDF]

, 2009
Streams are potential hotspots for retention and removal of NO3−, and understanding the mechanisms that enhance NO3− reactivity in stream systems is critical for predicting and preventing eutrophication.
