Sophisticated plant breeding techniques have brought us blight-resistant potatoes and crops enriched with nutrients; flood-tolerant scuba rice that can survive under water for a fortnight or more; and drought-tolerant maize that increases yields by up to 30%.
Common gradients include precipitation, soil nutrients, flooding, elevation, and temperature, and disturbances range from the very severe (e.g., landslides) to the moderately severe (conversion to agriculture) to the least severe (tree fall, selective logging).
The Nutrient-Flood Connection Scientists have established a clear link between nutrients in the Mississippi and the Gulf dead zone.
That involves measuring factors such as nutrient uptake, flood alleviation and the presence of suitable plants.
Traditionally, farmers have sought out the best places to plant their crops – nutrient rich flood plains and the sides of volcanoes.
The nutrient retention, flood damage reductions, carbon sequestration, and biomass production capacity of retention basins may provide the necessary economic and environmental benefits for their widespread adoption.
On-site impact of soil erosion such as reducing the soil quality as the most fertile upper layer gets lost easily while off-site impact caused increased water turbidity, nutrient enrichment, flood, and poor water quality (Sholagberu et al. 2016; Barrow et al. 2009; Khairulmaini and Fauza 2010).
AM fungi can form symbiotic associations with the roots of most terrestrial plants and provide many benefits including improved nutrient uptake, flood and drought resistance, and herbivore resistance [ 13, 65].
Comparative analysis of phytoplankton biomass measured in plume conditions with co-factors such as flow and salinity (Figure 6) is key information for understanding the response of phytoplankton standing stock to the input of nutrient-enhanced flood waters.
However, foliar δ15N levels in seedlings of P. violacea growing in a high nutrient environment in flood debris piles did not differ from levels recorded in seedlings of the reference tree.
This river space is to be preserved for the sake of ecology, riparian vegetation and nutrient recycling during floods.
