El objetivo del presente trabajo fue evaluar en sistemas extensivos el peso vivo al servicio y la prolificidad en borregas y ovejas Corriedale, Texel, Finnish Landrace, Frisona Milchschaf y sus cruzas. Entre los años 2012 y 2014 se realizaron 924 observaciones de 409 corderas de tres generaciones. Las ovejas Finnish Landrace y 3/4 Finnish Landrace – 1/4 Corriedale fueron las más livianas al servicio. Se encontraron diferencias en más de 15 kg entre los biotipos con menor y mayor PV (i.e. Finnish Landrace vs. Frisona Milchschaf). Los biotipos con sangre Finnish Landrace tuvieron la mayor prolificidad. El biotipo Finnish Landrace x Texel presentó una prolificidad de 62% superior al Texel puro. Se han identificado algunos biotipos promisorios capaces de incrementar sustancialmente la prolificidad en sistemas extensivos. |

The sustainable management of forest plantations by keeping the harvest residues on site improves the soil?s chemical, physical and biological properties while constituting an important nutrient reserve. Our objectives were: (a) to identify and quantify the characteristics of Eucalyptus dunnii, Eucalyptus grandis and Eucalyptus globulus that affect the decomposition rates of harvest residues, as well as indicators that can explain the process and (b) to quantify the potential recycling of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg) to the soil from residue decomposition and the quantitative and qualitative differences between the species. We analyzed the information of five commercial plantations of Uruguay. At the harvest, the biomass of leaves, thin and thick branches, bark and their respective N, P, K, Ca and Mg contents were quantified. At each site, bags with samples of the different residues were left to decompose and were periodically collected throughout 24 months. Eucalyptus dunnii presented the largest amounts of residues of all parts. The decomposition rates of the different residues depended on their chemical constitution, part size and the species. Eucalyptus dunnii leaves showed the shortest half-life (0.94 years), while the bark of the same species presented the longest (5.62 years). Total nitrogen and carbon (total and soluble) contents, which can be easily determined, emerged as good predictors for half-life estimation. The release patterns of nutrients depended more on their dynamics in the plant and their parts than on the species itself. The results highlight the importance of nutrient recycling to ensure the sustainability of the productive system in the medium and long term. © 2023 by the authors. Licensee MDPI, Basel, Switzerland.
