Biogeochemical nutrient cycles and nutrient management strategies [PDF]

Hydrobiologia, 1999
Nutrient loading by riverine input into estuarine systems has increased by 6–50 times for the N load from pristine conditions to present, whereas a 18–180 times increase has been observed in the P load. Reductions in the ratio of N to P delivery has also occurred with time.

Polyhalite as an alternate nutrient source for improving growth, yield, and nutrient use efficiency in onion and garlic

Scientific Reports
Polyhalite (POLY4), a naturally occurring multi-nutrient source with a low salt index, has potential as a replacement for muriate of potash (MOP). A field experiment was conducted to assess the effect of POLY4 on the growth, yield, quality, and nutrient ...

Calcium—Nutrient and Messenger [PDF]

Frontiers in Plant Science, 2019
Calcium is an essential element needed for growth and development of plants under both non-stressed and stress conditions. It thereby fulfills a dual function, being not only an important factor for cell wall and membrane stability, but also serving as a second messenger in many developmental and physiological processes, including the response of ...
