Background

  • Sustainable agriculture requires efficient resource management.
  • Optimizing straw, water, and nitrogen is crucial for agroecosystems.
  • Understanding the water-nitrogen-carbon nexus is key for environmental protection.

Purpose Of The Study

  • To investigate synergistic straw, water, and nitrogen utilization in a tomato-corn-soybean agroecosystem.
  • To quantify the water-nitrogen-carbon nexus interactions.
  • To evaluate the impact of different straw utilization strategies on sustainability.

Main Methods

  • Quantified water-nitrogen-carbon nexus interactions.
  • Evaluated straw utilization strategies (e.g., straw return, biochar).
  • Assessed impacts on water footprint, carbon footprint, economic benefits, and system coordination.

Main Results

  • Optimized water and nitrogen reduced water and carbon footprints by 2.25-5.46% and 3.37-13.82%.
  • Economic benefits and quality improved by 8.27-21.06% and 4.06-7.63%, respectively.
  • Straw return and biochar enhanced system coordination by 1.41-9.62%.

Conclusions

  • Synergistic resource management optimizes agroecosystem sustainability.
  • Straw utilization strategies significantly impact environmental and economic outcomes.
  • Findings support decision-making for balancing resource use, food security, and environmental protection.

The Nitrogen Cycle 01:49

51.4K

Nitrogen atoms, present in all proteins and DNA, are recycled between abiotic and biotic components of the ecosystem. However, the primary form of nitrogen on Earth is nitrogen gas, which cannot be used by most animals and plants. Thus, nitrogen gas must first be converted into a usable form by nitrogen-fixing bacteria before it can be cycled through other living organisms. The use of nitrogen-containing fertilizers and animal waste products in human agriculture has greatly influenced the...

Key Elements for Plant Nutrition 02:35

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

The oceans are one important focus of global conservation efforts. Overfishing,...

Overview of Nitrogen Metabolism 01:20

Nitrogen is a very important element for life because it is a major constituent of proteins and nucleic acids. It is a macronutrient, and in nature, it is recycled from organic compounds and stored in the form of  ammonia, ammonium ions, nitrate, nitrite, or  nitrogen gas by many metabolic processes. Many of these metabolic processes are carried out only by prokaryotes.
The largest pool of nitrogen available in the terrestrial ecosystem is gaseous nitrogen (N2) from the air, but this...

The Roles of Bacteria and Fungi in Plant Nutrition 02:11

Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

The collective bacteria residing in and around plant roots are termed the rhizosphere. These soil-dwelling bacterial species are incredibly diverse....

Adaptations that Reduce Water Loss 01:57

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

In land plants, the uppermost cell layer of a plant leaf, called the epidermis, is coated with a waxy substance called the cuticle. This hydrophobic layer is composed of the polymer cutin and...
