Evaluation of soil extractants for silicon availability for sugarcane
(2018-10-21)
Adequate evaluation and interpretation of silicon (Si) phytoavailability in soil is a key to fertilizer recommendation. This study was conducted to determine the effect of soil texture on the choice of Si extractant, and ...
Laser-induced breakdown spectroscopy to determine soil texture: A fast analytical technique
(2016-02-01)
The analysis of soil texture is crucial for the proper management of agricultural systems and for environmental studies. Soil texture is important as it affects erosion potential, water retention capacity, organic matter ...
CAN SOIL PENETRATION RESISTANCE AND BULK DENSITY BE DETERMINED IN A SINGLE UNDISTURBED SAMPLE?
(Soc Brasileira De Ciencia Do Solo, 2015-05-01)
Soil quality indicators such as penetration resistance (PR) and bulk density (BD) are traditionally determined in a single undisturbed soil sample. The aim of this study was to assess the effect of PR measurements of ...
Change of textural density as an indicator of the instability in coarse-textured soilsMODIFICACION DE LA DENSIDAD TEXTURAL COMO UN INDICADOR DE LA INESTABILIDAD EN SUELOS DE TEXTURA GRUESA
(Facultad de Ciencias Agrarias. Universidad Austral de Chile, 1998)
PHOSPHORUS FERTILIZATION AND SOIL TEXTURE AFFECT POTATO YIELD
(Univ Fed Rural Semi-arido-ufersa, 2018-07-01)
Potato (Solanum tuberosum L.) is a nutritionally demanding crop, and phosphorus (P) is a nutrient that exerts a large effect on tuber yield. However, as the availability of P is influenced by soil texture, there are doubts ...
Direct measurement and prediction of bulk density on alluvial soils of central Chile
(Inst Investigaciones Agropecuarias, 2016)
The significance of soil bulk density (rb) as a key indicator
of soil quality was examined in this study. Bulk density
values obtained by direct methods (clod, cylinder, and
excavation) with three sample sizes (small, ...
The impact of agriculture on soil texture due to wind erosion
(2015-01)
Wind erosion produces textural changes on topsoil of semiarid and arid environments; however, the selection of particles on different textured soils is unclear. Our objectives were to evaluate textural changes induced by ...
Potato yield and phosphorus nutrition using humic substances in two soil textures
(Empresa Brasil Pesq Agropec, 2020-01-01)
The objective of this work was to evaluate the effect of humic substances (HS) and phosphorus fertilizer on the growth. P uptake, tuber yield, fertilizer P recovery (FPR), and applied P-use efficiency (APUE) of potato ...
