Soil Science
Air, water, organic matter, and minerals are the components of this material.
What is soil?
This is a type of irrigation method.
What is Center-pivot, furrow, or drip irrigation?
This is how public rangeland is it utilized in animal agriculture
What is grazing livestock?
These are substances that can be administered to livestock to promote growth, increase milk production, or regulate reproductive cycles.
What are hormones?
This type of fishing has the lowest rates of bycatch.
What is pole fishing?
This is primarily made from decaying plants and animals
What is humus?
This type of irrigation method is generally considered the most water-efficient
What is drip irrigation?
This greenhouse gas is primarily released by ruminant animals like cattle during digestion
What is Methane?
These are medicines used to treat or prevent bacterial infections in livestock
What are antibiotics?
This fishing method involves dragging a net along the sea floor and is highly destructive to benthic communities.
What is trawling?
Soil is made of these three different soil particles.
What is sand, silt, and clay?
This is a major con of furrow irrigation.
What is significant water loss due to evaporation and runoff?
These are the two reasons pasteurization is considered important
What is kills harmful bacteria in milk and extending its shelf life?
This government agency is responsible for regulating livestock production, processing, and labeling in the United States
What is the USDA (United States Department of Agriculture)?
The loss of the Atlantic Cod around Newfoundland occurred because those fisheries were this.
What is overexploited?
The type of weathering breaks rocks into smaller pieces without changing their chemical composition
What is mechanical weathering?
These are the three primary macronutrients essential for plant growth
What are Nitrogen (N), Phosphorus (P), and Potassium (K)?
This is the primary characteristic that broiler hens have been bred for
What is rapid growth and efficient meat production?
This is one advantage of center-pivot irrigation.
What is irrigate large, circular areas efficiently, and labor requirements are relatively low?
This zone, extending 200 nautical miles from a country's coast, gives a nation exclusive rights to marine resources
What is an exclusive economic zone?
This horizon layer is the topsoil, rich in organic matter and nutrients, and is where most biological activity occurs.
What is horizon A?
This is how fertilizers help to improve soil fertility.
What is adding essential nutrients (like N, P, K) to the soil, supplementing what might be naturally lacking and supporting plant growth?
This is the difference between veal and beef production regarding the age of the animal
What are young calves, (typically a few weeks to a few months old)?
Beyond killing bacteria, this is another benefit of pasteurization for milk
What is extending shelf life?
To be successful, fishing quotas must be set at or below this level for a fishery.
What is the maximum sustainable yield?
