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 ...
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 ...
What Are the Impacts of Long-Term Vinasse Application on Clayey and Sandy Soils?
(2022-04-01)
Long-term vinasse application effects evaluation on the chemical and physical attributes of soils with different textures is fundamental to support waste application recommendation. The aim was to evaluate whether long-term ...
Evolution of iron crust and clayey Ferralsol in deeply weathered sandstones of Marília Formation (Western Minas Gerais State, Brazil)
(2017-11-01)
Extensive flat plateaus are typical landforms in the cratonic compartment of tropical regions. Paleoclimate, pediplanation, laterization, and dissection have created complex and distinct geological, geomorphological, and ...
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 ...
Multivariate analysis of peanut mechanized harvesting
(2018-03-01)
The peanuts harvesting mechanization is affected by the soil physical characteristics and it may increase the losses due to the production of pods in subsurface. The objective of the experiment was to identify the clusters ...
Statistical process control applied to mechanized peanut sowing as a function of soil texture
(Public Library Science, 2017-07-24)
The successful establishment of agricultural crops depends on sowing quality, machinery performance, soil type and conditions, among other factors. This study evaluates the operational quality of mechanized peanut sowing ...
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 ...
Dynamics of diuron and sulfentrazone formulations in soils with different textures
(2020-01-01)
Background: The use of commercial mix and tank mix with two or more herbicides is a widespread practice. However, despite its several possible benefits, little is known about its effect on the behavior of the molecules in ...
Differential tolerance of eucalyptus clones to sulfentrazone applied in different soil textures
(2016-03-01)
This study aimed to evaluate the visual injury and concentrations of chlorophyll in two eucalyptus clones submitted to sulfentrazone application, at different doses and in soils with different textures. Experiments were ...
