High cation exchange capacity and organic matter content of crude humic substances from compost could be exploited to reduce ammonia loss from urea and to as well improve rice growth and soil chemical properties for efficient nutrients utilization in lowland rice cultivation. Close-dynamic air flow system was used to determine the effects of crude humic substances on ammonia volatilization. A p...

effect of gibberellic acid on marigold (calendula officinalis l.) was evaluated in a pot culture experiment. a factorial experiment based on completely randomized design including 12 treatments and four replications was carried out. main factor was foliar application stages (first, second and third) and sub factor included different concentrations of ga3 (0, 50, 150 and 250 mg l-1). results sho...

Introductions of high yielding inorganic fertilizer are not cheap and leave behind a large amount of dry matter for disposal. Thus there is a need to utilize these plant residues to save fertilizers and maintain a satisfactory level of soil fertility. Hence, with the view of in-situ manuring as well as to recycle the agricultural residue, pot experiments were conducted to study the effect of wh...

Lab Service Wiki is a Semantic MediaWiki implementation for the management of a production laboratory. Here we describe its implementation on a protein service lab. Users of the service enter information about a sample and the desired analysis to be performed by using a semantic-enabled form built on top of a wiki page. After submitting, a workflow is created, and the manager of the service can...

To cope with the growing population, there is a demand for more land to be rendered cultivable. A complex soil created by applying soft rocks into sandy can cultivated. However, strong water-retaining ability and extreme poverty in nutrients of this has negative effect on plant growth. solve problem, microbes bacterial manure (BM) was added soil. The column culture test used detect influence BM...
