Sources of Agricultural Productivity
Some sources of agricultural productivity are:
- Mechanization
- High yield varieties, which were the basis of the Green revolution
- Fertilizers: Primary plant nutrients: nitrogen, phosphorus and potassium and secondary nutrients nutrients such as sulfur, zinc, copper, manganese, calcium, magnesium and molybdenum on deficient soil
- Liming of acid soils to raise pH and to provide calcium and magnesium
- Irrigation
- Herbicides
- Pesticides
- Increased plant density
- Animal feed made more digestible by processing
- Keeping animals indoors in cold weather

Famous quotes containing the words sources of, sources and/or productivity:
“The sources of poetry are in the spirit seeking completeness.”
—Muriel Rukeyser (1913–1980)
“Even healthy families need outside sources of moral guidance to keep those tensions from imploding—and this means, among other things, a public philosophy of gender equality and concern for child welfare. When instead the larger culture aggrandizes wife beaters, degrades women or nods approvingly at child slappers, the family gets a little more dangerous for everyone, and so, inevitably, does the larger world.”
—Barbara Ehrenreich (20th century)
“It is ultimately in employers’ best interests to have their employees’ families functioning smoothly. In the long run, children who misbehave because they are inadequately supervised or marital partners who disapprove of their spouse’s work situation are productivity problems. Just as work affects parents and children, parents and children affect the workplace by influencing the employed parents’ morale, absenteeism, and productivity.”
—Ann C. Crouter (20th century)
