SEGOVIA, 6 Feb. (EUROPA PRESS) –
The Prodestur deputy, Magdalena Rodríguez, has presented this Monday the Soil Map of the northwest of the province of Segovia, which is expanded to 38 municipalities, focuses on the agricultural region of El Carracillo and is a tool that is already available in the website where you can see, plot by plot, the nutritional availability of the soil, its composition and an analysis of irrigation water.
In addition, as a novelty, it is associated with an individualized fertilization plan according to the characteristics of the crop.
The study area covers a total area of about 1,509.39 square kilometers, of which 667.70 kilometers are cultivated area, which represents 21.8 percent of the total for the province.
The sampling of the area includes the collection and analysis of 499 samples, referring to the superficial layer (arable) of the soil, while the non-sampled areas correspond mainly to forest areas.
As explained by the deputy responsible for the laboratory, “one of the most visible results of the project is the creation of maps of the different parameters analysed, corresponding to a basic soil analysis: texture, pH, electrical conductivity, organic matter, carbonates total, nitrogen and assimilable phosphorus and potassium content, and carbon/nitrogen ratio.
For Magdalena Rodríguez, this tool “is essential because it makes it easier for producers and technicians to make decisions about production areas depending on the crop.”
In addition, this application relates the results of the analysis with the nutrients required by the crop, the level of its extraction and the expected productivity.
In this way, it allows locating a specific plot, obtaining its fertility data and interpreting it, and defining a subscriber plan for a specific crop.
In the words of Rodríguez, “the program gives the option of incorporating certain variables, such as the results of the last soil analysis, selecting the crop, expected production, organic amendment contributions, crop residues*”.
To complete the project, data on the irrigation waters of all the municipalities have been associated to the maps, specifically the values of pH (soil acidity), salinity, hardness and Riverside classification.
These data, the deputy continued, “provide relevant information, since the pH influences the solubility of fertilizers and the availability of nutrients to plants; salinity as it limits the development and production of crops; hardness due to its impact on irrigation systems, and the Riverside classification for being the most widely used agronomic classification for the characterization of water types”.
Thus, the municipalities included in the study area are: Aguilafuente, Aldea Real, Carbonero el Mayor, Chañe, Cuéllar, Fresneda de Cuéllar, Frumales, Fuente el Olmo de Íscar, Fuentepelayo, Gomezserracín, Hontalbilla, Lastras de Cuéllar, Mata de Cuéllar, Mozoncillo, Navalmanzano, Pinarejos, Pinarnegrillo, Remondo, Samboal, San Cristóbal de Cuéllar, San Martín and Mudrián, Sanchonuño, Vallelado, Zarzuela del Pinar, Aldeanueva del Codonal, Aldehuela del Codonal, Bernardos, Coca, Domingo García, Fuente de Santa Cruz, Migueláñez, Nava de la Asunción, Navas de Oro, Nieva, Ortigosa de Pestaño, Santiuste de San Juan Bautista, Villaverde de Íscar and Villeguillo.
