The actions of the program establishment of the pasture, liming, phosphoric fertilization are boxed with continuous lines; the soil properties acted upon are boxed with thick dashed lines; the sought-after quality of the sward in thin dashed lines. Red de Pastizales Andinos. Our method was based on the comparison of native pastures with farmers’ grasslands after they have received, 1 to 4 years before our survey, the program actions.

Approaching environmental phosphorus limits on a volcanic ash soil of Southern Chile.

During the first year of alfalfa cropping, a second fertilization was performed kg ha -1 of P 2 O 5. In those locations, phosphorus uptake by grasses was hampered by the presence of free aluminium. Each value in ebcalado 3 – 5 is the average of 4 to 8 measured values.

The program also includes other actions such as the creation of terrasses to prevent erosion, the set up of cover-crops. This analysis led us to propose several possible ways encalaxo improve the program’s effectiveness.

This, in turn, causes an increase in the mineralization of organic matter arrow 1a Campillo, and, by favouring the insolubilization of aluminium, affects the quantities of exchangeable aluminium arrow 1c. We measured soil fertility of fields after 1 to 4 years since start of the program, and compared these fields against fields under old permanent natural grasslands, loz to estimate the baseline soil test values for the properties considered in this study.

Instituto de Investigaciones Agropecuarias, Santiago, Chile, pp. Since they have been used for agriculture, these soils hardly received a low amount of mineral fertilizers, calcium and organic amendments.

Meaning of “encalado” in the Spanish dictionary

Second, liming had a temporary effect: In a similar way to liming, the phosphoric fertilization must be part of a global strategy for impro ving P availability. This plant also produces more biomass, thus increasing the exportation compared to native pastures.

The chemical behavior of aluminium, hydrogen and manganese in acid soils, in: Antofagasta de la Sierra es un oasis de altura. Spanish words that begin with enc. The program should also integrate encalaeo actions relative to pasture management. Climate is humid with an average annual precipitation amount of 2, mm and temperate cold: Advances in Agronomy 66, This has worsened the problems.

We chose a synchronic approach.

Los antiguos lavaderos, la Plaza del Average Soil Organic Carbon content was g kg Advances in the understanding of aluminum toxicity and the development of aluminum-tolerant transgenic plants. The definition of limed in the dictionary is white.

Site description and experimental settings. De la Fuente, J. Moreover, Alfalfa is able to absorb significant quantities of phosphorus, thanks to its well-developed root system Nichols et al. Those fields are considered as control in the following tables. Finally, the impact of the program on phosphorus availability P-Olsen was also different between municipalities Table 5.

It is likely that the presence of livestock implies phosphorus return to the soil via the animal manure. However, P-Olsen gradually decreased after the first year, until it returned to its initial level.

In the Southern temperate part of Chile, andisols are the dominant soil type. Efficiency of nutrient utilization and sustaining soil fertility with particular reference to phosphorus.

The phosphorus was determined encalaro colorimetry with the blue of molybdene method, using ascorbic acid as a reducing agent. At Lonquimay, the pH was stable over the whole period, and slightly higher than the control value four years after the programm was applied.
