The program also aims at establishing a pasture with variable compositions to ensure a permanent coverage of the soil, thus limiting erosion and increasing productivity and quality of forages.
The definition of limed in the dictionary is white. These changes show poor effectiveness of the program to recover soil acidity in the area investigated. This program has been operational for more than a decade. 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. As seen above, the actions taken in the program were unable to correct consistently the pH in all localities but Lonquimay.
Arrows in Figure 1 shows relationships between program actions and changes expected in the soil. We chose a synchronic approach.
In those locations, phosphorus uptake by grasses was hampered by the presence of free aluminium. Medicago hispida or Lotus uliginosus. For example, new methods of nitrogen fertilization, based on a nitrogen wcidez, should be spread and the use of urea should be avoided.
Advances in the understanding of aluminum toxicity and the development of aluminum-tolerant transgenic plants. However, P-Olsen gradually decreased after the first year, until it returned to its initial level.
Acidez de los suelos y efectos del encalado
Subdivision of the 32 fields sampled in each municipality, with reference to the application of the program at the time of measurement. We also share information about the use of the site with our social media, advertising and analytics partners. Finally, afalfa was only harvested as hay, without any return of P to the soil, which probably impeded the P balance sheet. Journal of Soils and Sediments 14 9 They were compared to fields that received the program one, two, three or four years earlier and were located near enough of the control plots so that the characteristics in terms of soil condition and cultivation history were similar.
Jean Roger-Estrade E-mail address: That flora consisted mainly of grasses Agrostis capillaris, Holcus lanatus and some naturalized legumes plants e. It is more likely due to the unsufficient amount of lime added to the soil: In a similar way to liming, the phosphoric fertilization must be part of a global strategy for impro ving P availability.
The aim of this study was to assess the effect on soil quality of a governmental program whose objective is restoring the fertility of degraded acidic volcanic ash soils. Encalado de alfalfa en suelos Trumaos del Sur de Chile. Antofagasta de la Sierra es un oasis de altura. Finally, the productivity and the quality of the pasture should benefit from the decrease in pH arrow 6the decrease of exchangeable aluminium arrow 5 and the increased availability of phosphorus arrow 4.
In this area phosphoric fertilizer was first applied kg ha -1 of P 2 O 5just before the alfalfa was sown. Conocidos estos datos pueden adoptarse las siguientes directrices: The program also includes other actions such as the creation of terrasses to prevent erosion, the set up of cover-crops.
Discover all that is hidden in the words on. Advances in Agronomy 66, These conditions are very hard on the Mapuches farmers of this area, whose main activity is cattle breeding ovine and bovine and whose farms are very small.
This has worsened the problems.

A sample of 2. Los antiguos lavaderos, la Plaza del Synonyms and antonyms of encalado in the Spanish dictionary of synonyms. Application of the program had different effects on the pH of the soil in the different locations studied Table 3. Advantages of high density planting of hazelnut orchards in South Chile; preliminary data, in: 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, used to estimate the baseline soil test values for the properties considered in this study.
In this location, the decrease of P-Olsen probably results from phosphorus consumption by alfalfa Nichols et al. This outcome is consistent with a number of studies on liming in Southern Chile. Low Science Society of America Journal 76 2 The number of fields studied is shown in table 1.
Second, liming had a temporary effect: Spanish words that begin with enc.
