This variable pertains to optional Conservation Practices provided by NTT. This variable is constant with respect to Crop type in the specific application. Contour buffer strips are permanent, narrow bands of grasses/legumes planted on the contour (across or perpendicular to a slope) between wider strips of crops. Contour buffers trap sediment and enhance filtration of nutrients and pesticides by slowing down runoff that could enter the local surface waters. This is the type of grass or vegetation that will be present in the buffer sections of the contour buffer.
