Overuse of different chemical fertilizers is one of the causes for the degradation of environment and soil. Biological fertilizers are the newest and most technically advanced way of supplying mineral nutrients to crops. Compared to chemical fertilizers, their supply nutrient for plant needs, minimizes leaching, and therefore improves fertilizer use efficiency. Vermicompost is an organic compou...

Fertilization Effects We often learn about things in science by serendipity. And when it comes to learning about bryophytes in ecosystems, we often learn by what we do to their neighboring tracheophytes. Hence, when we fertilize our gardens or add fertilizers to restore impoverished land, the bryophytes respond along with the intended tracheophytic plants. In general, fertilizers are detrimenta...

Wheat, which is one of the most widely cultivated crops in world, has great importance terms economy. Wheat basic food sources human beings, first plants. In order to meet nutritional needs parallel with increasing population, agricultural production be increased. Fertilization important factor yield. Innovations fertilizer technology and improvement use efficiency are importance. this study, d...

in order to study the effects of integrated application of bio-fertilizer and chemical fertilizers on yield and yield components of corn, an experiment was conducted in 2008 in dezful city, (khoozestan province) in a factorial arrangement based on complete randomized block design with four replications. treatments were integrated application of biological and chemical fertilizers in four levels...

SALA�, P.: Slow-release fertilizers and possibilities of their utilizing in nursery. Acta univ. agric. et silvic. Mendel. Brun., 2004, LII, No. 2, pp. 155-164 Reserve, slow-release fertilizers (SRF) enable to simplify the whole system of plant nutrition and fertilisation. Tabletted fertilizers of the Silvamix series represent a prospective product of Czech provenience. At our university, these ...

Since the 1940s, the widespread adoption of synthetic fertilizers has reduced the need for manure as a nutrient source in crop production. This has led to separation of crop and animal production, increased use of imported feeds, and a growth in animal numbers relative to land area on dairy and other livestock farms. A net flow of nutrients into areas with a concentration of dairies is now comm...

It has been reported that phosphate solubilizing bacteria (PSB) are the most promising bacteria among the plant growth promoting rhizobacteria (PGPR); which may be used as biofertilizers for plant growth and nutrient use efficiency. Moreover, these soil micro-organisms play a significant role in regulating the dynamics of organic matter decomposition and the availability of plant nutrients such...

The USDA established the National Organic Program (NOP) to develop national standards for organically produced agricultural products and establish an organic certification program as required by the Organic Foods Production Act (OFPA) passed by Congress in 1990. Organic crop production excludes conventional pesticides, petroleum – based fertilizers, and sewage sludge based fertilizers with some...

A pot experiment was carried out with maize to determine the phosphorus (P) plant-availability of different secondary P-fertilizers derived from wastewater. We analyzed the respective soils by P K-edge X-ray absorption near-edge structure (XANES) spectroscopy to determine the P chemical forms that were present and determine the transformation processes. Macro- and micro-XANES spectroscopy were ...
