[2] Porter Farm had been selected by the community to participate in the project, with $1000 set aside to cover potential losses.

Knapp worked with Walter Porter to set aside 70 acres (28 ha) of the farm, on which the experimental use of fertilizers on some plots and rotation with nitrogen-fixing legumes doubled normal yields of cotton.

The success of this project led to the creation of government Extension Service programs, which went on to develop methods to combat boll weevil infestation in the area.

[3] The Porter Farm is located about 2 miles (3.2 km) north of Terrell, on FM986.

Today a tomato barn, which is not historically significant, stands on that land.
