Tracking nitrogen losses in a greenhouse crop rotation experiment in North China using the EU-Rotate_N simulation model [PDF]

open access: yes, 2010
Vegetable production in China is associated with high inputs of nitrogen, posing a risk of losses to the environment. Organic matter mineralisation is a considerable source of nitrogen (N) which is hard to quantify.

Organic, mineral and organomineral fertilizer in the growth of wheat and chemical changes of the soil

open access: yesRevista Brasileira de Ciências Agrárias - Brazilian Journal of Agricultural Sciences, 2019
The organomineral fertilizers can release organic compounds during their solubilization, and those compounds can affect the plant growth. The aim of this study was to evaluate the initial development of wheat, nutrient accumulation in the plant and soil chemical changes, with the use of organic, mineral and organomineral fertilizers. The experiment was

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Natural regulation of Delia radicum in organic cabbage production [PDF]

open access: yes, 2013
In a field experiment, we evaluated effects of three different organic white cabbage-cropping systems (O1, O2, O3) on the cabbage root fly, Delia radicum, and its egg predators and pupal parasitoids over 3 years.

Influence of Organic-Mineral Fertilizer Rates on the Performance of Wheat Varieties in Azerbaijan

open access: yesBulletin of Science and Practice
In recent years, a lot of work has been done to develop agriculture in Azerbaijan. The purpose of the research was to study the Onur and Alekseevich varieties and evaluate their yield and grain quality. The studied varieties had higher indicators (protein, vitreousness) in the variants with the introduction of vermicompost at a rate of 1500 kg ...
