Lettuce is among the 10 most valued vegetables for fresh consumption in Brazil. The use of rock powder lettuce crops soil acidity correction or fertilization an option reducing production costs. In this context, objective study was to evaluate effects rates mica schist and irrigation water depths on development characteristics crops. conducted experimental area State University Goiás, using pelletized seeds cultivar Crespa Vanda. A randomized block design with four replications used, a 4 ×...
The objective of this study was to develop and calibrate a photovoltaic-powered soil moisture sensor (SMS) for irrigation management. Soil readings obtained from the were compared with gravimetric measurements. An automated SMS used in two trials: (i) okra crop (Abelmoschus esculentus) (ii) chili pepper (Capsicum frutescens). All sensors calibrated using an Arduino Mega board C++. data subjected descriptive statistical analysis. recorded by equipment correlated method. determination...
The use of geotechnologies combined with remote sensing has become increasingly essential and important for efficiently economically understanding land cover in specific regions. objective this study was to observe changes agricultural activities, particularly agriculture/livestock farming, the North Forest Zone Pernambuco (Mata Norte), a political-administrative region where sugarcane cultivation historically been backbone local economy. region’s biomass also contributes observations...
Seasonally dry tropical forests (SDTFs) represent about 41.5% of the planet’s forests. The objective this study was to characterize annual mortality and recruitment patterns stems trees between years 2012–2021 in a Caatinga remnant state Pernambuco, Brazil, through geostatistical modeling, associate drought events recorded region with vegetation dynamics. Mortality were monitored 80 permanent plots located an SDTF remnant, counted year by 2012 2021. standardized precipitation index (SPI)...
Northeast Brazil (NEB), particularly its semiarid region, represents an area highly susceptible to the impacts of climate change, including severe droughts, and intense anthropogenic activities. These stresses may be accelerating environmental degradation desertification soil in NEB. The main aim this study was gain geospatial insights into biophysical parameters surface energy balance actual evapotranspiration on a multi-temporal scale, aiming detect analyze spectral behavioral patterns...

Seasonally Dry Tropical Forests (SDTFs) are situated in regions prone to significant water deficits. This study aimed evaluate and quantify the dynamics spatial patterns of vegetation bodies through analysis physical–hydrological indices for a remnant FTSD between 2013 2021. Basal area, biomass, tree number were monitored 80 permanent plots located two areas an SDTF with different usage histories. To assess resource conditions, geospatial parameters NDVI, NDWIveg, NDWI, MNDWI estimated...
A caatinga apresenta uma diversidade de fisionomias e um enorme quadro degradação, sendo importantes os estudos relacionados a fitossociologia para caracterização da vegetação. O objetivo deste trabalho foi realizar estudo florística em fragmento florestal no município Serra do Mel Rio Grande Norte. Para realização realizado levantamento vegetação adotando-se Amostragem Inteiramente Aleatória, onde foram marcadas 10 unidades amostrais 20 x m (400 m²). Foram amostrados todos indivíduos...
Thematic maps of land cover and use can assist in the environmental monitoring semiarid regions, mainly due to advent climate change, such as drought, pressures from anthropic activities, advance urban areas. The geotechnologies is key for its effectiveness low operating cost. objective was evaluate understand spatiotemporal dynamics loss gain a region Brazilian region, identify annual trends changing conditions over 36 years (1985 2020), using cloud remote sensing techniques Google Earth...
Precise estimates of dendrometric and morphometric variables are indispensable for effective forest resource conservation sustainable utilization. This study focuses on modeling the relationships between shape (morphometric), dimension (dendrometric) density (N) to assess sustainability resources. It sheds light current state site characteristics, reproduction, structure Araucaria angustifolia trees at selected remnants across multiple sites in Santa Catarina, Southern Brazil. Individual...
The density and distribution of three tree species local economic importance with, but sometimes without, thorns (Mimosa tenuiflora, Piptadenia stipulacea) or urticating hairs (Cnidoscolus quercifolius) thriving in native seasonally dry tropical forests, were assessed a 43.5-hectare cattle-grazed caatinga remnant, located Patos/Paraíba, Brazil. We recorded georeferenced all the thorny thornless regenerant plants (≥50 cm high circumference at breast height (CBH) < 6 cm). also mature trees...
Através deste estudo objetivou-se e conhecer analisar a diversidade florística-fitossociológica em área de caatinga sendo esta, mata ciliar no campus da UFCG Pombal, PB. Foi realizado um inventário florestal por meio amostragem sistemática, as parcelas espalhadas forma metódica, duas primeiras paralelas, onde ficava uma cada lado do rio, distanciando-se 50 metros das subsequentes. Foram alocadas 10 unidades amostrais com medidas 20 x m. Os indivíduos inventariados nas foram identificados,...
Objetivou-se com o presente trabalho analisar a estrutura fitossociológica de dois fragmentos florestais na Caatinga diferentes históricos uso e conservação. Os dados foram coletados no município Floresta – PE. O local vem sendo monitorado desde 2008, por meio parcelas permanentes 400 m², distribuídas em duas áreas 40 unidades cada, uma área conservada (AC) menos (AMC). Foram mensurados identificados botanicamente todos os indivíduos arbustivo-arbóreos circunferência 1,30 m do solo (C) ≥ 6...
The objective of this study is to evaluate the spatio-temporal dynamics land vulnerability and pasture areas in dairy basins states Pernambuco Alagoas, which are part Ipanema River Watershed (IRW) Northeast Region Brazil. Maps Land Use Cover (LULC); Index Vulnerability Degradation (IVD); (LVI); time series Effective Herd (EH), Milked Cows (MC), Milk Production (MP); Pasture (PC) Quality (PCQ) were created as parameters. An opposite pattern was observed between use classes Livestock,...
The Brazilian Cerrado biome provides relevant ecosystem services for Brazil and South America, being strategic the planning management of water resources as well agribusiness. objective was to evaluate quality along course Córrego da Formiga in a virgin portion Cerrado, relationship land use with physical-chemical biological parameters water, inflow tributary. Five collection points were defined (between source mouth) observed on quarterly scale 2015, samples collected analyzed laboratory,...
