Match the agricultural management practice with its description.
contour plowing
Planting crops directly into the residue of the previous year's crop.
crop rotations
Crops that are grown specifically to be plowed into the soil, adding both organic matter and nutrients in the process. They also prevent erosion by covering soil that would otherwise be left bare.
No-till agriculture
planting different crops back-to-back on the same plot of land to improve soil health, optimize nutrients in the soil, and combat pest and weeds.
Green manures
Plowing across hilly fields rather than up and down the slop of a hill which prevents water from running down the slope and taking the topsoil with it.
