Modeling and identification of fertility maps using artificial neural networks
(2000-12-01)
The application of agricultural fertilizers using variable rates along the field can be made through fertility maps previously elaborated or through real-time sensors. In most of the cases applies maps previously elaborated. ...
Phosphorus and potassium balance in soil under crop rotation and fertilization
(Universidade Estadual de Londrina (UEL), 2012-01-01)
The use of crop rotation and manure application can provide sustainability for an agricultural production system by improving soil quality and increasing nutrient use efficiency. This study aimed to evaluate the effect of ...
Silicon fertilization reduces the deleterious effects of water deficit in sugarcane
(2017-01-01)
Few studies have focused on water deficit for sugarcane, whose damage could be reduced with Si, as shown in other crops. This study aimed to determine whether Si fertilization enhances the best recovery of sugarcane after ...

Bovine biofertilizer and irrigation layers on lettuce development and leaf chlorophyll
(2014-01-01)
It is necessary and urgent the search by sources of organic fertilizer and decrease the consumption of water for irrigation. In the context, the aim of this study was to evaluate the nutritional effects of the use of bovine ...
Fertilization defects in sperm from Cysteine-rich secretory protein 2 (Crisp2) knockout mice: Implications for fertility disorders
(Oxford University Press, 2016-04)
STUDY HYPOTHESIS
We hypothesize that fertility disorders in patients with aberrant expression of Cysteine-RIch Secretory Protein 2 (CRISP2) could be linked to the proposed functional role of this protein in fertilization.

Fertility in Curitiba, Brazil: levels, trends and differentials
(DRUNPP-SARAJEVOSARAJEVO, 2012)
Objectives: To identify levels, tendency and recent differentials in fertility in Curitiba, Brazil. Methods: It is a quantitative and temporal series study, in which the birth rates, general and total fertility indicators, ...
Effect of foliar and substrate fertilization on lady palm seedling growth and development
(Taylor & Francis Inc, 2008-01-01)
Lady palm, [Rhapis excelsa (Thunberg) Henry ex. Rehder] is one of the most cultivated ornamental palms in the world, for use as a vase plant or in shaded landscapes. Because limited information exists on lady palm response ...
Soil P Diffusion and Availability Modified by Controlled-Release P Fertilizers
(Springer, 2020-11-24)
Slow-release fertilizers have been proposed as tools to increase P fertilizer use efficiency in tropical acidic soils with high P adsorption, low P availability, and mobility. However, results have been controversial since ...
