The program also aims at establishing a pasture with variable compositions to ensure a permanent coverage of the soil, thus limiting sueloa and increasing productivity and quality of forages. Load a random word. Synonyms and antonyms of encalado in the Spanish dictionary of synonyms.

Spanish words that begin with e. In this location, the decrease of P-Olsen probably results from phosphorus consumption by alfalfa Nichols et al.

Medicago hispida or Lotus uliginosus. At Lonquimay, P-Olsen initially significantly increased, showing a positive short-term effect of the program. We mixed the soil of eight sub-samples in each field.

Climate is humid with an average annual precipitation amount of 2, mm and temperate cold: En la India, Kalia ct al. 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. These changes show poor effectiveness of the program to recover soil acidity in the area investigated. The program should also integrate some actions relative to pasture management.

De la Fuente, J.

Site description and experimental settings. Efficiency of nutrient utilization and sustaining soil fertility with particular reference to phosphorus. Spanish words that begin with enc. Chilean Journal of Agricultural Research 71 2 This has worsened the problems. This study provided important results for the improvement of the program.

Arrows in Figure 1 shows relationships between program actions and changes expected in the soil. Soils of these five localities are classified suwlos andisols Vitric-Silandic Andosol as mentioned by Salazar et al.

The phosphorus was determined by colorimetry with the blue of molybdene method, using ascorbic acid as a reducing agent. In a similar way to acidze, the phosphoric fertilization must be part of a global strategy for impro ving P availability.

Meaning of “encalado” in the Spanish dictionary

As seen above, the actions taken in the program were unable to correct consistently the pH in all localities but Lonquimay. Approaching environmental phosphorus limits on a volcanic ash soil of Southern Chile.

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. 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. El impacto del programa sobre la acidez pH y aluminio intercambiable y disponibilidad de P fue diferente entre localidades.

This whole strategy is essential to keep a sufficient proportion of legume species in the pastures. This program has been operational for more than a decade.

P supply should be repeated in time. The aim of this study was to evaluate its effects on soil properties and on pasture productivity in the region of the Araucania, home of small producers Mapuche.

Moreover, Alfalfa is able to absorb significant quantities of phosphorus, thanks to its well-developed root system Nichols et al. Plant analysis of phosphorus retention capacity of allophanic and non allophanic Andisols.

This analysis led us to propose several possible ways to improve the program’s effectiveness. These characteristics strongly impede soil productivity, especially in the pastures, which are vital for small cattle breeders. For example, new methods of nitrogen fertilization, based on a nitrogen balance, should be spread and the use of urea should be avoided.

Subdivision of the 32 fields sampled in each municipality, with reference to the application of the program at the time of measurement. After filtering, measurements were taken using an atomic absorbtion spectrophotometer. At Cunco, exchangeable aluminum was not affected, while pH increased initially but decreased to its initial value within four years. A sample of 2.
