Potassium runoff and leaching losses in beef cattle production systems of southern Chile

IPNI-2006-CHL-5

The objective of this project is to establish the amount of K lost by leaching from livestock systems, so that corrections in fertilizer applications can be made into the beef cattle systems managements of southern Chile, increasing K applications as organic and inorganic fertilizers to correct losses.

Interpretive Summary

Livestock production in Chile is concentrated in the southern regions of the country and is largely based on a direct grazing system that has intensified over the last 10 years because of new commercial trade agreements signed by the country. This activity has increased application rates for N, P, and K fertilizer, stocking rates, and the intensity of rotational grazing. The objective of this study is to quantify K losses in surface run-off and leaching from grazed permanent pastures.

Chilean livestock production is concentrated in the southern regions of the country and is largely based on a direct grazing system that has intensified over the last 10 years because of new commercial trade agreements signed by the country. This more intensive land use has increased application rates for N, P, and K fertilizer, stocking rates, and the intensity of rotational grazing.

Chilean livestock production is concentrated in the southern part of the country and is largely based on a direct grazing system that has intensified over the last 10 years because of new commercial trade agreements signed by the country. This more intensive land use has increased amounts of N, P, and K fertilizer use per hectare, as well as stocking rates, and the intensity of rotational grazing.
