Potencial do hidrogel no cultivo de culturas anuais em solos degradados, Gilbués (PI)

Abstract

The hydrogel is worldwide facilitated by its great absorption capacity and water concentration within its gradual distribution structure for soil and plants. Developed by an American company of the 50's was launched in the 70's by a British company, having its water retention capacity to 400 times its own mass. In Brazil the use of hydrogen is more concentrated in planting grams for sports and gardens, in which agriculture is older with regard to a few works that have already been performed in the area. One culture in which the use of hydrogen became quite frequent is a eucalyptus, obtaining results in several types of tests. The hydrogel decreases the frequency of irrigation and help is one of the factors that most prevent the growth of regular areas in a longer time series. ground. For the non-experienced fertilization, the long-term dosing system was used, with efficiency in moisture retention and nutrient distribution. The soil used in the research comes from the degradation area of the city of Gilbués, located in the State of Piauí, where the Research Nucleus of Recovery of Degraded Areas and Combat Desertification (NUPERADE) is located. The recovery of a degraded soil is extremely difficult, although it is a natural process, a degradation can be intensified by human actions. Revegetation as areas are some of the lost recovery of low cost and efficient. The work was subclassified in 3 chapters, in chapter 1, seeking the performance of soil attributes in each treatment, in chapter 2 aum was followed for a week and in chapter 3 a corn and bean production was analyzed in degraded soil with hydrogel and biosolids
