The study was carried out on twelve runoff
plots installed at Kabete Campus Field Station,
University of Nairobi, on a 10% natural slope of
eutric Nitisol to assess the effect of grass strips
in controlling soil loss and runoff on sloping land.
Four treatments, a control plot without grass strip
and three different widths (0.5, 1.0 and 1.5 m.) of
Nandi setaria (Setaria anceps), were tested under
natural rainfall during 1982 and 1983, simulated
runoff, and simulated rainfall of 80 mm/hr.

In May 1980 the soil section of CIAT's cassava program established a fertilization trial with 3 cassava var. [Barranquena (regional), M Col 113, and CMC 921 to measure its effect on yield and establish optimum levels from an economical point of view. The trial took place in Mondomito and Agua Blanca, municipality of Santander de Quilichao, Cauca (Colombia). Twelve levels of NPK (0-0- 0; 0-100-100; 50-100-100; 100-100-100; 200-100-100; 100-0-100; 100- 50-100; 100-200-100; 100-100-0; 100-100-50; 100-100-200; 200-200- 200) were applied.

The paper recommends that a project be developed that assists several hundred people to become farm operators, through land purchase arrangements or long term land leases, on land that is government controlled.
