Evaluating the potential for snowmelt phosphorus losses from perennial forage crops. [PDF]

J Environ Qual
Abstract In cold regions, there is concern that losses of P with snowmelt runoff following freeze and thaw of vegetation may be greater from perennial forages relative to annual crops. We evaluate the drivers of P losses with snowmelt runoff over a network of field‐scale small watersheds in Manitoba, Canada, following annual crops (59 site‐years ...

Effect of humic acid on the growth and yield of two maize (Zea mays L.) cultivars on andisol

Ilmu Pertanian (Agricultural Science), 2020
One way to improve maize (Zea mays L.) production is through land extension using Andisol land. However, andisol soil has phosphate (P) fixation problem due to the high amorphous material. Hence, the use of organic material in the form of humic acid that

Aluminum dynamics in nitrogen‐saturated Andisols in Tokyo

Ecological Research, 2023
Abstract The debate over whether forests around the Tokyo metropolitan area are nitrogen (N) saturation persists, as atmospheric N deposition in throughfall has decreased. This decrease is evidenced by a notable decline in samples collected in the 1990s (especially 1991–1992 and 1995).
