Comparative Study Effect of Urea-Sulfur Fertilizers on Nitrogen Uptake and Maize Productivity.

Combined nitrogen (N) and sulfur (S) fertilization is a good management strategy to reduce N loss and increase the efficiency of N fertilizers to achieve high grain yields and quality. Field trials for 2 yrs. (2018-2019) were conducted to evaluate the comparative advantage of conventional urea (150 N kg ha) compared to urea+ ammonium sulfate (150 N kg ha), urea+ calcium sulfate (150 N kg ha), and urea cocrystals (CaSO.

The influence of fulvic acid on spring cereals and sugar beets seed germination and plant productivity.

The vegetations and fields experiments were conducted in 2017-2018 at Rumokai Experimental Station of the Lithuanian Research Centre for Agriculture and Forestry. The influence of naturally occurring fulvic acids on the germination of spring wheat and barley and sugar beet seeds, development of plants and their yield and quality was investigated. The use of fulvic acids for seed dressing reliably increased the final germination percentage and decreased the mean germination time in spring wheat, spring barley, and sugar beet.

Relationship between CO emissions and soil properties of differently tilled soils.

Different tillage technologies have different effects on CO emissions from soil. Unfortunately, little information exists about the impact of different types of tillage as compared with no-tillage, and the main controls. The aim of this research is to determine the relationship between physicomechanical, chemical and biological properties of soil and CO emissions from differently tilled soils under the climatic conditions of central Lithuania before and after autumn tillage.
