Crop productivity and soil quality after fertilization with liquid swine manure
(2017-01-01)
An unresolved question about the use of animal waste in agriculture is its effect on the physical and chemical attributes of soil, especially in commercial grain producing areas that have adopted direct seeding system ...
Evaluation of different foliar fertilizers on the crop production of sugarcane
(2013-03-01)
Influence of different foliar fertilizers (phosphite, micronutrients, biostimulant, phosphite + micronutrients, phosphite + biostimulant, micronutrients + biostimulant and phosphite + micronutrients + biostimulant) on yield ...
Composted sewage sludge in replacement of mineral fertilization on wheat production and development
(2016-07-01)
Several research lines are required to ensure a proper disposal of sewage sludge in Brazil; among them, we may highlight agricultural use. In this sense, this study aimed at assessing the effect of exchanging nitrogen ...
Fontes e doses de NPK em milho irrigado sob plantio direto
(2011-04-01)
Coated fertilizers can provide lower losses and higher soil nutrients availability, which can be absorbed by plants, when we consider their gradual release. The objective of this study was to evaluate the effect of doses ...
Analysis of yield response variability to nitrogen fertilization in experiments performed in the Argentine Pampas
(Taylor & Francis, 2008-12)
Nitrogen (N) fertilization has become a common practice in corn and wheat crops in the Argentine Pampas during the past decade. In this region, great environmental variability determines erratic responses to fertilization. ...
Are ch4, co2, and n2 o emissions from soil affected by the sources and doses of n in warm-season pasture?
(2021-06-01)
The intensification of pasture production has increased the use of N fertilizers—a practice that can alter soil greenhouse gas (GHG) fluxes. The objective of the present study was to evaluate the fluxes of CH4, CO2, and ...
Corn yield in sandy soil fertilized with poultry litter
(United Arab Emirates Univ, 2017-12-01)
The use of animal waste is an alternative to provide nutrients and increase organic matter content in sandy soils. The poultry litter is one of the most nutrient-rich residues. The objective of this study was assess the ...
Chemical properties of the soil fertilized with potassium and calcium in guava cultivation cv. 'Paluma'
(2018-11-01)
Soil fertility gradually declines over time and under continuous cultivation. It negatively reflects on the yield and quality of crop production, including guava, which is a perennial fruit of high economic potential. ...
Impact of clinical varicocele and testis size on seminal reactive oxygen species levels in a fertile population: a prospective controlled study
(ELSEVIER SCIENCE INC, 2008)
Objective: To investigate: 1) the impact of clinical varicocele on reactive oxygen species (ROS) levels in neat and washed semen in a proven fertile population; and 2) the correlation between ROS levels, testicular volume, ...
