Such strategy should be based on a balance of P that takes into account the increase of output due to the increase of the pasture productivity. Soil Science 8 The solution was shaked for 30 minutes and filtered. Spanish words that begin with enc. The cm layer was sampled. Soil Science Society of America Journal 76 2 The number of fields studied is shown in table enxalado.
For the analysis of exchangeable aluminium, 5 g of dry soil were added to a solution of ammonium acetate 1M, and shaken for 30 minutes, before filtering. Exchangeable Al content measured in different localities of the precordillera and the cordillera, Araucania Region south of Chile.
Nitrification and acidification drom urea application in red soils ferrallitic cambisols after different long-term fertilization treatments.
Acidez de los suelos y efectos del encalado | Horticulture International
Chemical properties of volcanic soils affected by seven-years rotations. These characteristics strongly impede soil productivity, especially in the pastures, which are vital for small cattle breeders. In each area, we selected fields that had not been subjected to the program these old permanent grasslands were considered to represent the soils in their natural, poor fertility status, and therefore these soils were used to estimate the baseline or “initial” soil test values for the properties considered in this study.
Moreover, acidity is high in those soils, which is also detrimental to phosphorus availability Pinochet et al. Cultivation practices in the five localities studied. Examples of use in the Spanish literature, quotes and news about encalado. Chilean Journal of Agricultural Research 71 2 After filtering, measurements were taken using an atomic absorbtion spectrophotometer.
At Lonquimay, the pH was stable over the whole surlos, and slightly higher than the control value four years after the programm was applied. Advances in the understanding of aluminum toxicity and the development of aluminum-tolerant transgenic plants.
El impacto del programa sobre la acidez pH y aluminio intercambiable y disponibilidad de P fue diferente entre localidades. However, these have been seldom applied in the area object of this study, and therefore they will not be discussed in this paper.
Meaning of “encalado” in the Spanish dictionary
Urea acidifies soils and can cause an increase in the amount of exchangeable aluminium Zejiang et al. The quantities of lime provided initially must be reconsidered and, most of all, it is necessary to repeat the liming every years in order to have more lasting effects on the pH and, consequently on the encaado Al content.
For example, new methods of nitrogen fertilization, based on encaladl nitrogen balance, should be spread and the use of urea should be avoided. Soil research 53 7 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. Encalado de alfalfa en suelos Trumaos del Sur de Chile.
Climate is humid with an average annual precipitation amount of 2, mm and temperate cold: P supply should be repeated in time. Average Soil Organic Carbon content was g kg During the first year of alfalfa cropping, a second fertilization was performed kg ha -1 of P 2 O 5. The program also includes other actions such as the creation of terrasses to prevent erosion, the set up of cover-crops.

ENCALADO – Definition and synonyms of encalado in the Spanish dictionary
Moreover, grasslands in those municipalities are grazed, as opposed to Lonquimay, where only hay is harvested. This plant also produces more biomass, thus increasing the exportation compared to native pastures. Lastly, this strategy must also integrate phosphurus recycling through cattle manure. We also share information about the use of the site with our social media, advertising and analytics partners.
The definition of limed in the dictionary is white.
The program focuses on improving the availability of phosphorus through phosphate supplements and liming, in order to decrease acidity and the content of free aluminium in the soil. At Cunco, exchangeable aluminum was not affected, while pH increased initially but decreased acixez its initial value within four years. Red de Pastizales Andinos. A second possible explanation of these results can be given by the generalized use of urea for nitrogen fertilization in this area, it is the cheapest nitrogen fertilizer source.
Discover all that is hidden in the words on. Cultivation practices of the different fileds studied are presented in table 2. Spanish words that begin with e.
In a similar way to liming, the phosphoric fertilization must be part of a global strategy for impro ving P availability.
