Soil salinization and sodification, caused by inadequate land management, is one of the main threats to the semiarid agroecosystems. It is essential to investigate saline levels under different land-use conditions to maintain the sustainability of agricultural production. The main objective of this study was to diagnose the salinity status of the s...
ABSTRACT - Cultivation of soybean and off-season corn is advancing in areas under restricted edaphoclimatic conditions, such as petric plinthosols, which have significant proportions of gravel and are deficiency in micro-nutrients such as copper (Cu) and zinc (Zn). The effects of Cu and Zn concentrations on soybean nutrition cultivated in petric pl...
This study aimed to analyze rice straw alternative managements to maximize the rice-soybean succession yield and to quantify their impacts on soil properties. The experiment was set up in a completely randomized design with six replicates. Nine rice straw managements were evaluated: straw burning (M1), straw harvesting (M2), straw incorporation wit...
Highlights: Soil Color can be used to quantify various soil attributes. The objective of this study is to develop a free and simple app called ?Soil Color?. The app determines soil color index using digital images.
The Amazon Region has archaeological soils called Amazonian Dark Earths (Terras Pretas de Indio) which are very efficient in retaining a large amount of highly stable organic matter when compared to typical non-archaeological soils in the region. The objective of this study was to determine the distribution, in- depth, of the carbon concentrations ...
Considering that changes in climatic parameters directly interfere in crop yields, this study aimed to evaluate the impact of changes in carbon dioxide concentrations, temperature and soil water availability on production, water-use efficiency and onion (Allium cepa L. cv. IPA 11) quality. Four levels of soil water availability (40, 60, 80 and 100 ...
