“…The strong association between the MiP, FC and AW soil properties in the CCC area may be explained by the greater homogenization due to tillage applied for crop cultivation, thus reducing pores and increases water retention (Martins et al 2018). However, the similarity between the EAC area in the subsurface layer and the DNV area may be due to a lower decomposition of plant residues in the subsurface (Zancada et al 2003), which results in low aggregation capacity of the soil in deeper layers and consequently in the degradation of the physical properties of the soil.…”

Deforestation of Caatinga and inadequate land use of these dry environments have impacted soil quality in Northeastern Brazil. The objectives of this study were: (a) to evaluate the effect of deforestation and different agricultural uses on the physical and chemical properties of soil, and humic fractions of soil organic matter in dry environments; and (b) to detect the soil properties that were most affected by anthropic actions. We evaluated four dry areas in Chapada do Araripe, NE Brazil: preserved native vegetation; degraded native vegetation; cassava conventional cultivation; and eucalyptus agro-energy cultivation. Soil fertility, total organic carbon and humic fractions of soil organic matter were lower in the degraded native vegetation area. The best indicators for soil quality evaluation were: macroporosity; bulk density; soil resistance penetration; sum of bases (mainly Ca 2+ ); available P; and saturation by Al 3+ . Total organic carbon and humic acid fractions of soil organic matter were important in improving soil quality. These properties were influenced by deforestation and agricultural uses, suggesting that the deforestation of native vegetation in dry environments has high capacity to degrade the soil, preventing its regeneration.

“…The amount of exchangeable bases in areas of preserved vegetation are naturally low (Martins et al 2018). Allocation of these nutrients to plant biomass and its return to the soil through the cycling process adequately nourishes the plants (Leite et al 2010).…”

“…The changes at soil, response to a given condition or management system can only be understood through the integrated analysis of a minimum set of parameters that are affected by different land uses, which can influence the ecological system as a whole (MARTINS et al, 2019;SIQUEIRA, 2006).…”

Validation of soil quality index in soil using bioindicator plant

Soils provide a broad set of vital ecosystem services and sustains the production of food and fibers, balancing the ecosystem. Thus, from the perspective of soil quality, it is defined as an ability to balance within the ecosystem to sustain biological productivity, promoting the health of plants and animals, being evaluated by traditional indicators as physical, chemical and biological indicators, so the present work aims to estimate the soil quality index using multivariate models using soil biological attributes and validation with growth variables of the bioindicator plant. The study was developed in the agricultural area in P. Prudente, SP, the points collected were georeferenced, collections in depth of 0 -20 cm, microbiological analysis, microbial carbon and nitrogen biomass, dehydrogenase, respiration and microbial coefficient, having a bioindicator plant curly lettuce (Lucy Brown) as a validator of the soil. The results were discovered using the PCA model for the identification of autos vectors and autos values, grouping and identifying their collinearities, linear regression, r-pearson validation and cluster heuristic analysis. The microbial attributes and the bioindicator plant discriminated the agricultural areas evaluated with establishment and validation of SQI. The metabolic coefficient and N of the microbial biomass dissipation of the highest covariance values by multivariate analysis. The reforestation area with native species (SQI0.782%) and the livestock crop integration system (SQI0.765%) were evaluated as areas with better soil quality

“…Plant extraction associated with fires exposes the soil to erosive agents, constituting the leading causes of desertification processes in the northeastern semi-arid region of Brazil (Barros & Chaves, 2014;Efthimiou et al, 2020). Martins et al (2019) state that the intense degradation of the Caatinga drastically reduces plant biomass production and increases direct soil exposure, resulting in reduced abundance and diversity of species and changes in soil fertility, thus increasing soil erosion.…”

Nutrient Reduction in the Initial Growth of Caatinga Tree Species

et al. 2021

This study aimed to evaluate the influence of nutrient omission on the growth and phytomass production of three tree species native to the Caatinga biome cultivated in degraded Chromic Luvisol samples, under greenhouse conditions. The experiments were conducted from april to june 2015. Three experiments were set up corresponding to three tree species [Myracrodruon urundeuva (Allemão), Caesalpinia ferrea (Mart. ex Tul.), and Amburana cearensis (AC Smith)], in a completely randomized design with eight treatments referring to the addition or not of nutrients to the soil and four replications. The results revealed that Fe and Zn supply was essential for the initial establishment of M. urundeuva and A. cearensis in Chromic Luvisols. For C. ferrea, which has a higher growth rate, fertilization with N, P, and S sources is necessary in addition to Fe and Zn in order to increase its establishment potential in these areas.
