Nitrogen1
Grass cover crop species such as cereal rye ( Secale cereale L.) can scavenge nutrients such as nitrogen (N) from deeper soil layers, avoiding losses by leaching and releasing them as residues decompose. (unl.edu)
Flows1
The nutrient input flows and output flows were monitored over a period of 3 years (2012-2014) using the monitoring for quality improvement toolbox. (wur.nl)
Biotic1
General areas of interest include plant breeding, intercrop interactions, nutrient use efficiency, root physiology, biotic and abiotic stressor resistance, and edaphic selection. (ubc.ca)
Dynamics1
Farms and wild lands can become agro-ecosystems by designing them to mimic ecosystem form (layered woodland canopy) and functions (water cycles, carbon sequestration, food web dynamics) while enhancing human access to goods (fruit, lumber, water) and services (shade, windbreak, debris composting). (growingformarket.com)
Farms1
Agroecosystems, which are defined spatially as individual crops or farms, occupy approximately 35% of the ice-free land area. (versicolor.ca)
Manure1
Like in many East African countries, nutrient depletion rates are exacerbated in Ethiopia by high erosion rates, biomass and animal manure removal from farm plots and limited application of mineral and organic fertilizers. (wur.nl)
Crops1
Well managed cover crops offer nutrient cycling benefits. (unl.edu)
Organic3
High cation exchange capacity and organic matter content of crude humic substances from compost could be exploited to reduce ammonia loss from urea and to as well improve rice growth and soil chemical properties for efficient nutrients utilization in lowland rice cultivation. (hindawi.com)
This reuse of biowaste allowed the recycling of nutrients and improved the level of organic matter. (intechopen.com)
In many ecosystems a significant part of the nutrients is stored in the organic rich part of the soil. (uva.nl)
