The impact of a urea-formaldehyde (UF) fertilizer on bacterial diversity in onion bulbs and main roots of sugar beet were examined using a 16S rRNA gene clone library. The UF fertilizer markedly increased bacterial diversity in both plants. The results of principal coordinates analysis (PCoA) revealed that nearly 30% of the variance observed in bacterial diversity in both the onion and sugar be...

Agrotain has shown in previous studies on silt loam soils to be much less prone to ammonia volatilization loss and to result in higher rice-grain yields compared to urea when the flood cannot be applied immediately after nitrogen (N) fertilizer application. However, no research has been conducted to determine if Agrotain is superior to urea as an N source for rice grown on clay soils, which vol...

Rainfall is a driving force for the transport of environmental contaminants from agricultural soils to surficial water bodies via surface runoff. The objective of this study was to characterize the effects of antecedent soil moisture content on the fate and transport of surface applied commercial urea, a common form of nitrogen (N) fertilizer, following a rainfall event that occurs within 24 hr...

Problem statement: This experiment was carried out for study the effects of chemical and biological fertilizers and interaction between them on some physiological characteristic and yield and its components of seed corn in two different irrigation. Approach: The experiment was conducted in a split plot factorial with completely randomized block design using four replications. Sub plots consiste...

This study examines the agronomic response, efficiency and profitability of fertilizer microdosing in maize. An experiment with the following treatments was conducted: control without fertilizer, microdosing treatments, with the rate of 27 + 27, 53 + 53 and 80 + 80 kg ha, and banding of fertilizer with 100 + 100 kg ha of di ammonium phosphate (DAP) + urea, applied at planting and jointing, resp...

This study aims to ascertain how production inputs affect cassava farming and examine use as efficiently possible. The research location was selected because the area is a center for production. Cobb-Douglas function model an analytical technique used assess output. Analyze level of input utilization optimization at same time by comparing marginal product's value other inputs. study's variables...

Solution and suspension N sources have been developed as substitutes Cor urea in spray solutions used by lawn-care proCessionals. A field study was conducted to evaluate the response of Kentucky bluegrass (Poa prarensis L.) growing on a Catlin silt loam (Typic ArgiudoLl), to applications oC the nell' solution and suspension N sources, alone or combined with urea, by comparison to turC response ...

Despite the importance of anhydrous ammonia (AA) and urea as nitrogen (N) fertilizer sources in the United States, there have been few direct comparisons of their effects on soil nitrous oxide (NO) and nitric oxide (NO) emissions. We compared N oxide emissions, yields, and N fertilizer recovery efficiency (NFRE) in a corn ( L.) production system that used three different fertilizer practices: u...
