Conserve
The practice of zero- or reduced-tillage, permanent organic soil cover, and crop rotations in agriculture.
What is conservation agriculture?
This phenomenon can cause serious health problems by blowing soil particles and microbes into the air, aggravating allergies and asthma.
What is wind erosion?
What are effects of global warming/climate change?
More pests, more weather extremes, loss of biodiversity.
This practice provides groundcover and adds organic matter to the soil with beneficial effects on several soil processes, including rainfall infiltration, soil aggregation, soil biological activity and soil nutrient cycling. I could go on.
What is mulching?
The role conservation agriculture holds in scientific and policy thinking about sustainable intensification in sub-Saharan Africa.
What is the dominant paradigm?
Direct effects of soil degradation include not only declines in crop yields, but also in this.
What are declines in nutritional content of food?
Sub-Saharan Africa consumes only 2% of the world of this, while China does 30%.
What is nitrogen fertilizer?
If farmers added this practice to control weeds, their yields were significantly better in conservation agriculture.
What is herbicide?
Increasing production from existing cropland with a lower environmental impact over the long run.
What is sustainable intensification?
Studies of impacts of climate change show declines in these of 10-50% by 2030s.
What are crop yields?
This phenomenon creates toxic aquatic algal blooms, fish death and loss of biodiversity.
What is nitrogen run-off and leaching?
They are popular. Cows, cooks and soils fight over them at the end of each season.
What are crop residues?
This conservation agricultural practice alone has no significant impact on yields.
What is no-till or reduced/low-tillage?
According to Bruce et all, this SDG is considered to be central to to achieve SDG 13 - Climate Action.
What is SDG 12 - Responsible Consumption and Production?
Excessive use of this particular broad-spectrum herbicide has led to weed-resistance, in addition to negative environmental and human impacts.
What is glyphosate?
If you are free, this strategy to adapt to climate change works.
What is time of sowing?
What are micronutrients important for soil productivity?
Zn, Cu, Mo, B, Se.
Largest yield benefits from conservation agriculture are not obtained in high-rainfall but rather low-rainfall areas because of this positive effect of conservation agriculture on soils.
What is soil moisture retention?
According to Lal, this is the key element in the feedback loop between malnutrition leading to poor agricultural management/soil erosion.
What is lower labor productivity (due to poor health resulting in less labor input)?
By sticking carbon into the soil and keeping it there, this practice can make farmers money.
What is regenerative agriculture?
