1. Grazing management under integrated crop-livestock system on physical soil attributes and grain yield soybean
ABSTRACT Integrated crop-livestock system (ICLS) can help improve the soil physical attributes, increasing the nutrients cycling and yield potential. We evaluated the effect of forage height management under ICLS on physical soil attributes and water infiltration. Field experiment was carried out for two consecutive years in a randomized complete block desig

2. CORRELATION OF SOIL PHYSICAL ATTRIBUTES WITH FURROWING SHANK STRENGTH AND DEPTH IN A NO-TILL SEEDER
ABSTRACT Furrowing shank horizontal strength and working depth can be correlated with soil compaction in a no-till sowing. This study aimed to evaluate the correlation of furrowing shank strength and working depth with soil physical properties at two working speeds (1.58 and 1.87 m s-1) and four compaction levels induced by an agricultural tractor (0P, 1P, 3

3. Least limiting water range in Oxisol under two conservation tillage systems in sugarcane farming
ABSTRACT The Least Limiting Water Range (LLWR) is an indicator of soil physical quality, contributing in information to propose soil management systems in agricultural farming process. This work aimed to assess the usage of LLWR and critical soil bulk density for physical-water quality evaluations, as well as its effect on sugarcane farming under no-tillage

4. Carbon and Nitrogen Stocks Under Different Land-Use in the Paraopeba River Basin-MG Before the Corrégo do Feijão Dam Burst
ABSTRACT Soil attributes can provide indicators for the management and conservation of natural and agrarian ecosystems. This study was carried out before the rupture of the Córrego do Feijão dam and aimed to evaluate and quantify the stocks of carbon, nitrogen and the C/N ratio in soils around the Paraopeba-MG river basin in five regions corresponding to t

5. FERTILIZER RECOMMENDATION METHODS FOR PRECISION AGRICULTURE – A SYSTEMATIC LITERATURE STUDY
ABSTRACT Spatial variability management of soil chemical attributes is one of the approaches to be employed in the face of the constant challenge of increasing agricultural yield to meet world demand. In this sense, precision agriculture has as one of its tools the application of inputs at varying rates, which seeks to determine the ideal amount of fertilize

6. Soil attributes and spatial variability of soil organic carbon stock under the Atlantic Forest, Brazil
Resumo Para explorar os atributos físicos e químicos do solo e espacializar o estoque de carbono orgânico do solo em um trecho de Floresta Atlântica (Estacional Semidecidual Submontanal, Espírito Santo, Brasil), este estudo avaliou quatro camadas de solo (0-5, 5-10, 10-20 e 20-40 cm), as inter-relações dos atributos físicos e químicos e a espacializ

7. PHYSICAL-HYDRAULIC ATTRIBUTES AS INDICATORS OF FUNCTIONALITY OF SOIL PORES UNDER DIFFERENT COMPACTION LEVELS
RESUMO A compactação modifica o arranjo estrutural e as funções essenciais dos poros do solo. O trabalho teve como objetivo avaliar o impacto de diferentes graus de compactação em um Argissolo Amarelo sobre os atributos físicos-hídricos indicadores da funcionalidade dos poros. Foram utilizados cilindros de solo 0.05 x 0.05 m em 4 graus de compactaç�

8. Influence of the climate on productivity and the eucalyptus drought response and a proposal for maximizing wood productivity in function of soil attributes in Brazil
Resumo Os ganhos genéticos dos programas de melhoramento do eucalipto diminuíram em comparação com as décadas anteriores, enquanto a produtividade reduziu nos últimos anos. Essa queda é atribuída principalmente às mudanças climáticas, que, segundo estudos, têm limitado a produtividade e alterado a adaptação das espécies florestais. Além disso

9. Broccoli in succession to pearl millet: nutrient cycling, production and soil chemical attributes
ABSTRACT For its production, broccoli requires large quantities of nutrients in relatively short periods. As a conservation technique, the no-tillage planting of broccoli over the pearl millet straw in succession may interfere with the dynamics of nutrient release, inflorescence production and the chemical attributes of the soil. The objectives of this work

10. SPATIAL VARIABILITY OF SOIL APPARENT ELECTRICAL CONDUCTIVITY - EFFECT OF THE NUMBER OF SUBSAMPLES
ABSTRACT Soil apparent electrical conductivity (ECa) sensors have been used to detect spatial variability because they correlate with soil attributes. Studies with soil attributes have shown that the number of subsamples and sampling points influences mapping. However, there are no studies that investigated the influence of sampling or subsampling density on

11. SPATIAL AUTOCORRELATION OF PHYSICAL ATTRIBUTES OF AN OXISOL
ABSTRACT Studies that seek to identify a smaller number of soil attributes that represent others can generate less expenditure of time and financial resources for monitoring cultivated areas. Thus, this study aimed to analyze the spatial distribution and spatial autocorrelation of physical attributes of an Oxisol (Latossolo Vermelho Amarelo, Brazilian Soil C

12. CONTRIBUTION OF SOIL ATTRIBUTES AND MORPHOLOGICAL VARIABLES TO YIELD OF IRRIGATED GARLIC
ABSTRACT This study aimed to investigate relationships between the soil attributes that most affect garlic yield, which can be useful to choose a new area for the growing of this vegetable. We also aimed to study the effects of irrigation deficit at bulb formation stage (cloves) on final garlic quality and yield. The variables evaluated were garlic yield, ir
