Currently, along with the development of agriculture, a certain amount of organic waste is generated from products produced to meet the needs of the population. Organic waste can be recycled with the assistance of earthworms. The technology of processing organic waste using earthworms is of great theoretical and practical importance in solving biotechnological problems. In vermicompost with the help of local earthworms, the content of total nitrogen increased from 0.4 to 0.5%, total phosphorus — from 0.2 to 0.4%, total potassium — from 0.45 to 1.6%, calcium — from 0.15 to 1%, sodium — from 0.12 to 1%.

<p>Re-vegetation has been widely carried out to prevent land degradation, reduce soil erosion, and improve soil quality. In order to investigate the characteristics of soil nutrients content in different land use types of karst gabin basin, soil organic matter, soil total nitrogen, soil total phosphorus, soil total potassium, soil pH, and soil texture in woodland, agricultural land, orchard, and grassland were surveyed in Mengzi Gabin Basin, Southwest of China. The difference of soil indicators between vegetation types was analyzed, and soil fertility quality of four land use types was comprehensively evaluated by the soil quality index (SQI). The results showed that land use significantly affected soil organic matter content. Soil organic matter content was the highest in grassland, followed by agricultural land and forest land, while orchard was lowest. There was a significant difference in soil total nitrogen content between different land uses. The total nitrogen content in farmland soil was the highest, followed by grassland and woodland, and the lowest in the orchard. Woodand had the highest total potassium content and the lowest total phosphorus content. The grassland soil had the highest total phosphorus content and the lowest total potassium content. pH value in the four land use types was acidic, ranged from 5.82 to 6.67. The soil quality index showed that woodland had the highest soil fertility quality. The results of the study could provide the basis of soil nutrients variation and status in Gabin basin, and also provides support for evaluating the soil improvements during vegetation restoration in fragile Karst ecosystems.</p>

The present investigation entitled “Effect of sowing dates and establishment methods on quality parameter, uptake of NPK and economics of groundnut (Arachis hypogaea L.) under Konkan region of Maharashtra” was conducted at Agronomy Farm, Department of Agronomy, College of Agriculture, Dapoli, Dist. Ratnagiri, Maharashtra during kharif season of 2015. The results revealed that, the gross return (Rs. 209162 ha-1), net return (Rs. 69446 ha-1) and B: C ratio (1.50) was appreciably higher in 23rd MW as compared to the other sowing dates. However, broad bed furrow method of sowing obtained highest gross returns (Rs. 206615 ha-1), net profit (Rs. 68790 ha-1), and B: C ratio (1.50) as compared to flat bed method of sowing. The highest total nitrogen uptake (142.67 kg ha-1, total phosphorus uptake (11.45 kg ha-1) and total potassium uptake (67.82 kg ha-1) recorded under 23rd MW. Total nitrogen, total phosphorus and total potassium uptake was significantly higher in crop sown by broad bed furrow than flat bed.

In order to increase the efficiency of composting vinegar residue, the effect of different strain combination,a thermophiles(OP-2) and two rhizopus(FM1,SL10) combined,on the composting pocess and effect was studied. The results showed: Inoculating thermophilic bacteria OP-2 can increase the speed of composting vinegar residue, which can increase the heap temperature to 70°C in 7days ahead. Also inoculating inocula accelerated the mineralization of organic nitrogen. In the end of composting, the contents of total nitrogen、total phosphorus and total potassium, as well as GI were higher than the control treatment, which showed that inoculating inocula can accelerate the maturity process of composting vinegar residue and increase the composting quality.

Salak Sidimpuan leaf midrib is abundant pruning waste. Salak Sidimpuan leaf midrib can becomposted containing a number of nutrients (carbon, Nitrogen, phosphorus, and potassium) for plantgrowth. To speed up the process of composting of salak leaf midrib can be done by giving a numberof activators. This study aims to see the effect of activator on the level of elements C, N, P and Kcompost of salak Sidimpuan leaf midribs. This study used a one-factor randomized block design with4 levels of treatment of activator, K0 = control, K1 = chopped midribs+cow manure fertilizer, K2 =chopped midribs+EM4, K3 = chopped midribs+cow manure fertilizer+EM4) with three replications.Data were analyzed with ANOVA and continued with DMRT test at 5% level if the F test showed areal effect. The results showed that the K2 with treatment chopped salak Sidimpuan leaf midrib andEM4 activator tended to give the best results in reducing the levels of C-organic and C/N ratio aswell as increasing total Nitrogen, total phosphorus and total potassium after composting comparedto other activator delivery treatments.

Abstract A study was conducted to develop organic briquettes using biomass originating from slaughterhouse wastes and to investigate its potential as a nutrient source for plant growth. Dried rumen contents were mixed with fresh blood collected after bleeding of animals in different proportions and dried using tray drier. The dried rumen content-blood (RB) mixture was further mixed with commercially available coir pith in 12 different proportions. The rumen content-blood-coir pith (RBC) mixture was formed into briquettes using a hydraulic biomass briquetting machine. Each organic briquette was five cm in diameter and had an average weight of 30-40 grams. The treatments were analyzed for pH, moisture, electrical conductivity (EC), organic carbon (OC), total nitrogen, carbon: nitrogen ratio, total phosphorus and total potassium. Organic briquette having rumen content with 100 per cent blood and 80 per cent coir pith (T 10 ) recorded the highest total nitrogen, total phosphorus and total potassium content. The treatments for plant growth studies were selected based on the criteria that each treatment had highest values for at least two of the three primary nutrients of nitrogen, phosphorus and potassium. The treatments T 5 , T 7 , T 8 , T 10 and T 12 were selected for plant growth studies. Pot experiment using selected briquettes was carried out to determine the effect of selected briquettes on growth parameters and yield attributes of okra ( Abelmoschus esculentus ). Nutrient release pattern of the selected organic briquettes was also studied. The best desirable growth parameters and yield attributes of okra was observed in T 10 . Availability of nutrients in the medium were relatively less during first two months of planting (MAP), however, it significantly increased between 3 MAP and 4 MAP, which resulted in better plant growth and fruit yield. The study showed that there is great potential for development of organic briquettes using slaughter house wastes as an eco-friendly process, which are compact, easy to transport and market, and ideal for grow bag cultivation and garden nurseries

Stage System

Since 1983 approximately 150 full-scale emergent hydrophyte based wastewater treatment plants (reed beds) have been constructed in Denmark to serve small wastewater producers. The development of purification performance for 21 plants representing different soil types, vegetation, and hydraulic loading rates has been recorded. Cleaning efficiencies were typically in the range of 60-80% reduction for BOD, 25-50% reduction for total nitrogen, and 20-40% reduction for total phosphorus. The mean effluent BOD, total nitrogen and total phosphorus concentrations of the reed beds were 19 ± 10, 22 ± 9 and 6.7 ± 3.2 mg/l (mean ± SD), respectively. Thus, the general Danish effluent standards of 8 mg/l for N and 1.5 mg/l for P for sewage plants greater than 5,000 PE cannot be met by the present realised design of EHTS. The main problem observed in most systems is a poor development of horizontal hydraulic conductivity in the soil which results in surface run-off. Since the political demands for effluent quality will be more strict in the future, it is important to improve the performance of small decentral sewage treatment plants. On the basis of experiences from different types of macrophyte based and conventional low-technology wastewater treatment systems, a multi-stage system is suggested, consisting of sedimentation and sand filtration facilities followed by basins planted with emergent and submergent species of macrophytes and algal ponds.
