What is lateral reading?
A combination of fish and plant production using aquaculture and hydroponics systems
What is aquaponics?
Crops, the sequence in which they are grown, and the management practices used in an area over a period of time
What is a cropping system?
Process for making nitrogen fertilizer (ammonia) from nitrogen and hydrogen gas at high temperature and pressure
What is the Haber-Bosch process?
The surface removal of soil material from soils by the action of water or wind.
What is erosion?

The 4 soil health management principles
What are:
1.Minimize soil disturbance
2.Maximize biodiversity
3.Maximize living roots
4.Maximize soil cover?
Four solutions outlined in the article "Solutions for a Cultivated Planet" by Foley et al.
What is:
1) halting agricultural expansion,
2) closing ‘yield gaps’ on underperforming lands,
3) increasing cropping efficiency,
4) shifting diets and reducing waste.
Type of reduced tillage (name of tool) used by Rick Villnave.
What is a chisel plow?
Name of index of combined yields of different intercrops with respect to the yield of sole culture of the same crops. Value > 1 means that intercropping or stripcropping is better than monocropping.
What is Land Equivalent Ratio (LER)
Ability to rebound or recover from adversity. In the context of an agroecosystem or food system, it is the ability of that system to remain viable when affected by adverse forces, such as pest infestations, environmental degradation, economic downturns, etc.
