Improving Soil nutrients are essential for the sustainable

agriculture and to get higher yields.

Addition of manure to the soils can improve the soil

nutrients, soil health and crop yield.

Manure has been shown to be an excellent source of

plant nutrients.

To assess the influence of manure on soil properties including N,P

and K contents and crop yields under long term (10 years)

corn-soybean rotation in South Dakota.

Sampling and Data Collection

Study covers 12 years period from 2003

to present.

Soil samples were collected in fall after

harvesting (2003-2013).

Three samples from each plot were mixed

together to make a composite sample.
