Nitrogen and potasium levels are NOT primary measures of soil quality.

Explanation:

The deeper the soil horizon, the more fertile the soil. This is because this means the soil has had enough time to weather and release the elements/minerals held up in the parent rock.

Soil composition is also important for soil quality. The good ratio silt, clay, and sand can determine the quality of the soil. This same composition can determine the holding capacity of water in the soil for plants and other soil organisms.

Organic matter is important in raising soil quality. They ensure the soil retains water nutrients from leaching

To science we owe dramatic changes in our smug self-image. Astronomy taught us that our earth isn't the center of the universe but merely one of billions of heavenly bodies.
From biology we learned that we weren't specially created by God but evolved along with millions of other species.

Why was agriculture the worst mistake in human History?

Along with epidemic diseases, starvation, and malnutrition, farming also contributed to the creation of severe class distinctions.
Hunter-gatherers rely solely on the wild plants and animals they catch each day, with little to no food stored and no concentrated food sources, such as an orchard or a herd of cows.

Was the agricultural revolution good or bad?

Between 1700 and 1870, it is thought that both total agricultural output and output per worker increased by a factor of 2. 7 times.
Britain's agriculture is the most productive in Europe thanks to the Agricultural Revolution, with 19th-century yields up to 80% higher than the continental average.

Why are plastics hazardous to wildlife?

topjm [15]

In marine environment, many animals confuse the plastic littering the oceans for food including sea turtles. Once in these animal bodies the plastic accumulates, and the chemicals can cause excess estrogen to be produced, which has led to discoveries of male fish with female sex organs. For sea turtles, the plastic blocks their digestive tract and the food that is trapped releases gases that render them buoyant, and unable to dive for food. The turtle was slowly starving because a single use plastic bag, which she had eaten, was blocking her digestive tract.

The plastic contains destructible and harmful agents that is not good for human and animals health.
