It is well known that mechanochemically activated phosphate rock (MAPR) could improve extractable phosphorus (P) (extracted in 2% citric acid) greatly an ecological way. To evaluate the agronomic effectiveness of MAPR, we conducted a field experiment using spring maize Luvisol (pH 6.47) soil Northeast China for three consecutive years. Treatments consist variation P levels substitution triple s...

A consideration of fertilizer materials furnishing the three' major plant foods reveals the fact that sources of phosphoric acid and potash have remained almost constant while the sources of nitrogen have undergone decided changes. Superphosphate has been, and probably will continue to be, our main source of phosphoric acid in most fertilizer mixtures. In the year 1900, 79.8 per cent. of the to...

Sorghum bicolor is an important grain species used for food and feed production, where P a key element/nutrient in production. The effect of increasing phosphorus doses to sorghum Cerrado soil with sandy texture low fertility conditions was evaluated. study conducted at the Pântano Farm, Jataí, Goiás, Brazil. cultivar AG 1085. 0 (control), 40, 80, 120, 160 kg ha-1 P2O5 were used, whose source t...

Biopolymer-coated phosphorus fertilizers have shown promising results in slowing the release of P. However, their dissolution behaviour has been studied mainly water, and impacts on soil properties rarely addressed. The aim this study was to compare P from uncoated triple superphosphate (TSP) biopolymer-coated TSP at surface cropped Mediterranean soils evaluate pH distributions several pools. e...

A 45-day incubation and leaching experiments was conducted to determine the effect of different rates (0, 1, 2, 3, 5 t ha−1) enriched empty fruit bunches biochar (EEFB) inorganic fertilizer (91 kg ha−1 triple superphosphate—TSP) on availability losses phosphorus from sandy soil (tin tailing soil). The treatments for study were designated as T1—without (control), T2—inorganic treatment using TSP...

There is a paucity of data regarding the effect nutrient-enriched biochar amendments on nutrient dynamics in both soil and crops. This important because unlike pristine biochar, applied to minute quantities as large amounts may led over application nutrients loaded it. The current study examined effects phosphorus- nitrogen-enriched biochars macro micronutrients sandy leaf lettuce grown thereon...
