Charcoal-based fertilizers can be improved in quality by nutrient impregnation and modified to provide nutrients gradually (slow release fertilizer-SRF). SRF fertilizer made using a coating the form of charcoal from pyrolysis palm oil waste. Raw waste Bantur District, Malang, East Java, for soaking process with fertilizers, there are two different types namely organic (EM4) inorganic (Urea) aft...

In response to agriculture’s contribution surface water quality, considerable effort is being made develop best management practices reduce nutrient loss. To evaluate the efficacy of gypsum as a horticultural media amendment for controlling phosphorus (P) leaching, flue gas desulfurization (FGD) was added standard growth medium at 0, 2.5, 5, 10 or 15% (v/v). FGD either mixed with growing placed...

In an operational trial, increasing the amount of nitrogen (N) applied to container longleaf pine seedlings by incorporating controlled release fertilizer (CRF) into the media improved seedling growth and quality. Compared with control seedlings that received 40 mg N, seedlings receiving 66 mg N through CRF supplemented with liquid fertilizer had needles that were 4 in (10 cm) longer as well as...

A study was conducted to determine the efficacy of applying ground magnesium limestone (GML) or ground basalt in combination with bio-fertilizer to sustain rice production on an acid sulfate soil in Malaysia. Soils from Kelantan Plains, Malaysia, were treated with GML, ground basalt, bio-fertilizer, GML + bio-fertilizer, and ground basalt + bio-fertilizer (4 t ha 1 each). Results showed that so...

(Rocky Mountain juniper) and Potentilla fruticosa L. ‘Gold Drop (gold drop po ten til la) plants grown in containers had sim i lar or bet ter morphology, higher nitrogen con cen tra tions and contents, and high er N-use ef ficien cy when grown with liquid fertilizer ap plied at an exponentially in creas ing rate as compared to the same amount of N applied via controll...

In order to raise awareness about environmental protection, people are paying more attention now-a-days in reusing wastepaper. As a result, most countries in the world have already made significant progress related to wastepaper recycling technology. This study was conducted to investigate the effects of slow-release fertilizer (SRF) on Chinese cabbage production. Wastepaper was deinked and the...
