“…The results of this composting study are in agreement with Mondonca Costa et al (2015) [44], who observed a significant increment in nutrient content in the final compost compared to the raw materials. The same observation was found by Nishanth and Biwas (2008) [45] in a study on the effect of adding rock phosphate to treated compost. Liu and Price (2011) [36] also observed an increase in macro-and micro-nutrient concentrations in the final compost compared to the raw materials.…”

Abstract:Following the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident, the forests in the Fukushima area were highly contaminated with radiocesium ( 137 Cs and 134 Cs). Therefore, there is a need to develop strategies for remediation of the contaminated forests. We assessed changes in radioactive cesium ( 134 Cs and 137 Cs) contamination and nutrient status in composts derived from wood chip, bamboo leaf and bamboo powder using rice bran and wheat meal as sub-materials. Changes in soil properties and Komatsuna (Brassica rapa var. perviridis) growth were also investigated due the application of composts and initial materials at 0, 2.5, 5 and 10 kg·m −2 input levels. Mixing of sub-materials significantly reduced the concentration of radioactive Cs and improved compost quality. The effectiveness of three composts on soil quality improvement varied depending on their types and rates of applications. Amendments of bamboo leaf composts at 10 kg·m −2 resulted in the significantly highest soil inorganic N, available P and exchangeable K contents. Amendments of final composts also enhanced Komatsuna growth. Furthermore, radioactive Cs contaminations of the Komatsuna plants grown in these composts were below 0.1 Bq·kg −1 . This study may help to remediate the forests contaminated with radiocesium in the Fukushima area while improving the soil organic matter content to enhance soil sustainability.

“…Therefore, besides the active mechanisms of organic acids exudation connected to the intense microbial activity, the highest total K release, propitiated by the composts with powder phonolite, might be a reflex of the CEC increase of these sources when compared to the pure compost. Such possibility is supported by Nishanth and Biswas (2008) and Lima et al (2009), which observed expressive increase of the organic composts CEC that received mica residues.…”

Purpose Silicate rock powders have been appointed as possible nutrient alternative sources which might enhance the agricultural sector sustainability. However, the application of those materials directly in soil presents as main limitations the low content and solubility of the mineral nutrient sources. In this perspective, the aim of the present study was to evaluate, in a bioweathering perspective, the conjunct application potential of phonolite with organic composts over the nutrients release in soil, as well as the production and nutrition of brachiaria grass (Urochloa decumbens). In addition, it was sought to assess the composting process effectiveness in improving the nutrient release from this rock. Method An experiment was conducted with five treatments (control; enriched compost with powder rock at 10%; mixed compost with powder rock at 10%; solely powder rock; solely compost) and four repetitions. Results The alternative sources positively influenced the productivity, as well as the K and Si contents at the aerial part of the brachiaria grass and the nutrient release in soil. However, the conjunct applications of powder phonolite with organic composts were the source which the best promoted the total nutrient biorelease to soil. Conclusion Nevertheless, there was no evidence that the composting process promotes the phonolite bioweathering. On the other hand, the conjunct application of powder phonolite with organic composts, either as an initial component to the composting pile or additive to the stabilized composts, is a strategy which enhances the nutrient biorelease of the mineral source.

“…Enrichments in composting improve nutritive value; augment disease suppressive activity and beneficial microbial populations in the composts (Postma et al 2003;Biswas and Narayanasamy 2006;Pugliese et al 2011;Diaz et al 2011;Singh and Amberger, 1995;Nishanth and Biswas 2008;Biswas 2011;Meena and Biswas 2014). Such enriched composts partly substitute mineral fertilizer requirements (Adamtey et al 2009), improve soil organic matter stocks, augument soil quality and most importantly prevent loss of nutrient N through volatilization (DeLaune et al 2004;Steiner et al 2010).…”
