Developing Sustainable Agromining Systems in Agricultural Ultramafic Soils for Nickel Recovery

INVITED REVIEW Sustainable intensification in agricultural systems

†Background Agricultural systems are amended ecosystems with a variety of properties. Modern agroecosystems have tended towards high through-flow systems, with energy supplied by fossil fuels directed out of the system (either deliberately for harvests or accidentally through side effects). In the coming decades, resource constraints over water, soil, biodiversity and land will affect agricultu...

Developing sustainable systems for nematode management.

Early researchers identified key concepts and developed tactics for multiple-option management of nematodes. Although the emphasis on integrated pest management over the past three decades has promoted strategies and tactics for nematode management, comprehensive studies on the related soil biology-ecology are relatively recent. Traditional management tactics include host resistance (where avai...

Phosphate solubilizing microbes: sustainable approach for managing phosphorus deficiency in agricultural soils

Phosphorus is the second important key element after nitrogen as a mineral nutrient in terms of quantitative plant requirement. Although abundant in soils, in both organic and inorganic forms, its availability is restricted as it occurs mostly in insoluble forms. The P content in average soil is about 0.05% (w/w) but only 0.1% of the total P is available to plant because of poor solubility and ...

Nutrient Recovery Systems for Human Urine - Ways to Realize Closed Loop Sanitation and Future Sustainable Agricultural Systems

This paper provides an overview on the concept of closed loop sanitation systems. A brief outline has been given on existing sanitation facilities in India, ways to implement ecological sanitation and retrofitting of nutrient recovery systems into existing sanitation facilities. In recent times, though India has witnessed phenomenal development in water resources, access to adequate sanitation ...
