MAPPING OF PEDOLOGICAL POTENTIAL OF SOILS FOR CULTIVATION OF THE SUGAR CANE (Saccharum spp) IN PARAÍBA STATE USING GEOTECHNOLOGIES

Abstract

Agricultural planning, as a precept of environmental policy, is an instrument of great importance in the process of managing the rural space and agricultural activity. This work aimed to identify and map the soil information of the lands of the State of Paraíba for the sugar cane cultivation, aiming to recognize the potential of the physical environment. In the methodology, the Agricultural Zoning of the State of Paraíba and the digital map of soils were used in a data base elaborated in the software SPRING 5.2.2, extracted the pedological information of the soils and elaborated the pedological potential. The results showed that with the use of geoprocessing techniques it was possible the spatialization of the areas and the definition of the favorable environments of potential of the culture contributing to the reduction of the risks of degradation of the environment; The State of Paraíba presents a greater pedological potential for the cultivation of sugarcane in 10.04% of its total area; The areas identified as Very Low Potential correspond to 54.52% of the total area distributed throughout the State; The Argisols present the smallest and the Neosols the greatest impediments to the development of the culture; It was not possible to map smaller areas due to the scale of work, with the possibility of cultivating the sugar cane cultivation in small areas not identified in this study.

An Overview on the Potential of Silicon in Promoting Defence Against Biotic and Abiotic Stresses in Sugarcane

“…According to FAO (2015), agricultural productivity in low-latitude tropical regions tends to decline due to climate change. At the same time, being a perennial crop, the productivity of sugarcane is overwhelmingly influenced by climatic elements (Francisco et al 2017;Srivastava and Rai 2012). Although sugarcane is capable of tolerating certain limits of hostile climatic conditions, cane yield and productivity of sugarcane can also get severely affected by the changing climatic conditions due to global warming ( Fig.…”

Implementation of Climate-Smart Agriculture to Boost Sugarcane Productivity in Indonesia

“…Sugarcane is in most cases prone to climate change, although it can also be exceptionally adaptive (Srivastava and Rai 2012). Since sugarcane has a long growing season, and it remains in the soil throughout the year, its productivity can be supremely affected by climatic conditions (Srivastava and Rai 2012;Francisco et al 2017). Globally, climate change may affect crop growth directly through increasing temperature and changing rainfall, or circumstantially through the soil, nutrient, rising pests and pathogens attack (Hussain et al 2018).…”
