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 southwestern region of the Amazon has great environmental variability, presents a great complexity of pedoenvironments due to its rich variability of geological and geomorphological environments, as well as for being a transition region with other two Brazilian biomes. In this study, the use of pedometric tools (the Algorithms for Quantitative ...
O objetivo desse trabalho foi desenvolver um Sistema de Recomendação de Calagem e Adubação para cana-de-açúcar (SIRCA). O SIRCA calcula a demanda de nutrientes a partir da produtividade esperada e do Coeficiente de Utilização Biológico (CUB), com exceção do P, S e Zn, em que o SIRCA considera também o poder tampão do solo.
The objective of the study was to determine the common bean performance, grain yield and yield components of common bean as affected by bioactivation and different dosis of inorganic phosphorus.
The soil mineralogical constitution directly influences its chemical, physical and hydraulic characteristics. Although very important, it is still rarely used for decision-making in agriculture, mainly due to the complexity and cost of standard analyzes. In this sense, the middle infrared spectroscopy (mid-IR, 4000 to 400 cm(-1)) has great potentia...
ABSTRACT Swine wastewater can be used as a biofertilizer and promote significant improvements in soil physical-chemical attributes and yield. The objective of this study was to evaluate the effects of swine wastewater application on soil and maize yield. The experiment was conducted at the Agricultural Sciences Center of the Federal University of P...
peer reviewed / To understand and manage ecosystem complexity, it is important to determine the relationships between soil characteristics, human activities, and biodiversity. This study analyzes the relationships between vegetation, soil, and man-made damage with regards to land use change in the Fereydan region, Iran. Soil physical properties suc...

Assessment of soil nutrients and fertility status for three land use systems was carried out in Mokokchung, Nagaland, which lies under Eastern Himalayan region. Soil fertility indicators, viz., bulk density, soil pH, soil organic carbon, available Nitrogen (N), available Phosphorus (P), and available Potassium (K) were analyzed for Alder based fall...

Agriculture is a great emission source of CO2 into the atmosphere, contributing significantly to the greenhouse effect. Considering the hypothesis that there are differences in soil carbon dynamics due to the distinct physiological and morphological characteristics of sugarcane cultivars, the aim of this study was to characterize the short-term soi...
