Greater adoption of sustainable agricultural methods can help -- including enhanced nutrient use efficiency, phased out fertilizer subsidies, no-till or reduced tillage and other conservation measures, and closing the nutrient cycle
Water is the main ingredient for carbon accumulation in ecosystems, which stimulate biological processes and the nutrient cycle
Since we can't create more phosphorus, we have to close the nutrient cycle
within agricultural enterprises and beyond.
Some of this cut timber I leave in situ to rot down naturally, providing a home for woodland insects and microorganisms as part of the natural nutrient cycle
Beyond this, the growing international food trade can separate producer and consumer by thousands of kilometres, further disrupting the nutrient cycle
Their disappearance would break the nutrient cycle
and have knockon effects on water quality, animal populations and human communities.
Rod Cunningham, RSPB head of water policy, said: "Using the nutrient cycle
wisely is vital for agriculture, industry and the environment.
Instead of importing chickens from industrial agriculture operations, which are fed on imported corn meal and generate overwhelming mountains of chicken waste, many of the Hoje Taastrup residents use food scraps to feed the hens, then use the manure as fertilizer for their gardens--thus helping to close the nutrient cycle

Alliance Environmental is a recognized expert in the area of distributed green infrastructure and provides services to municipalities and private developments that seek to reduce the costs and environmental impacts of new and existing systems by optimizing water, carbon and nutrient cycle
Planting trees provides flood control by minimizing runoff and the loss of top soil, provides habitat and nutrition for wildlife and nurseries for local fish populations, and offers alternative economic livelihoods for local communities in the form of managing tree nurseries and planting, assisting with regulation of the water and nutrient cycle
That is a really powerful teaching tool," says Saxenian; "It turns the out-of-sight out-of-mind mentality around," and stimulates discussion of the nutrient cycle
