Bagasse was milled into small size of 0.200152 mm volume surface mean diameter. The powder was found to be a rich source of many macro and micro nutrients, namely Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, Sulphur, Iron, Manganese, Zinc, and Copper. FTIR spectrum indicates the possible presence of polysaccharides like cellulose, lignin and hemicelluloses, and polyphenols in the bagasse sample. Micro-images of the bagasse obtained through SEM shows the features of fiber structures. The fiber cells are cross-linked and surface seems to be rough and thick-walled. The fiber pith was found to have pits at some places. Proximate analysis through EDX shows the high proportions of Carbon (44.51%) and Oxygen (55.49%).

A study was made of the shape, dimensions and possible nutritional significance of the main root of the hemi parasite Nuytsia floribunda. Levels of nitrogen, phosphorus, potassium, sulfur, calcium, magnesium, sodium, iron, manganese, zinc and copper were determined in the main root: haustoria, xylem sap, mucilage, trunk and leaves. The main root was approximately turnip-shaped and there was no evidence of a tap-root. Haustoria were confined to the top 15-20 cm of the soil and were attached to a variety of woody and herbaceous host plants. Haustoria contained the highest levels of nitrogen and phosphorus, the trunk and main root the highest levels of calcium, magnesium and sodium. Potassium and sodium accounted for 75% of the minerals in xylem sap. calcium and magnesium for 60% of the minerals in mucilage which exuded from wounds in the main root. Concentration gradients of most minerals existed across the main root. Nitrogen, phosphorus, potassium, sulfur and sodium were more concentrated in the outer zone of the root, calcium, magnesium, manganese and copper in the central part. Nuytsia appears to draw on stored nutrients in some situations. Conservative estimates suggested that nutrient reserves in the main root could not provide the amounts required for flower and fruit production. It was concluded that reproductive and vegetative growth draws on reserves in organs other than the main root and the extensive lateral root system may be important in this respect.

The common bean has been object of breeding programs aiming the development of new cultivars adapted to varied production system and shown differentiated nutritional characteristics. Due a genetic diversity existent the landraces can be used directly for cropping, for present characteristics desirable. Little information exists about mineral content and other quality traits for those bean landraces. The aim of this paper was to verify the variability for grain nutricional caracters in breeding cultivars and landraces of bean from Rio Grande do Sul state, Brazil. The experiment was conducted in 2009/2010 in Experimental Station Cascata, of Embrapa Temperate Agriculture. In whole grain of 54 bean genotypes with black and no black coat were determined macroelements (nitrogen, phosphorus, potash, calcium, magnesium and sulfur), oligoelements (iron, manganese, zinc and cuprum), protein and ash content, insoluble fiber, digestive nutrient and antioxidant astragalina. The results shown that the landraces varieties presents nutritional composition of macro and oligoelements, fibers, protein and ash contents in whole grain similar than that of breeding lines and cultivars. The black coat grain from breeding programs showed better nutritional quality for macro and oligoelements content than coloured grain, highlighting TB 02-04 e TB 01-01. The landraces with coloured grains TB 02-26, TB 02-24 and TB 03-13 showed the high levels of astragaline.

To evaluate three procedures of the calculation of DRIS indices, as well as the efficiency of DRIS as a method for the interpretation of apple tree leaf analyses. This study uses data collected in apple producing areas of the Rio Grande do Sul and Santa Catarina States, Brazil. The concentrations of nitrogen, phosphorus, potassium, calcium, magnesium, boron, copper, iron, manganese, and zinc were determined in the leaf samples. The validation of the DRIS method used results of an experiment of potassium fertilization. The DRIS indices were calculated using two criteria for the choice of the ratio order of nutrients (F value ratio of variance of the relationships among nutrients between the reference group and the low productivity group, and R value - correlation coefficients between the productivity and the relationship between pairs of nutrients) and three forms of calculation of nutrient functions (methods of Beaufils, Jones and Elwali & Gascho). The Nutritional Balance Index (NBI) presented negative correlation with the productivity in all combinations. The DRIS method described by Elwali & Gascho, using the F value, presented a performance similar to the criterion of sufficiency range, and it can be used for the interpretation of foliar analysis of apple trees, because it presents values of the nutritional balance index that indicates the nutritional status of the plants, and for the efficiency in the nutritional diagnosis of the crop.

Leachate from containerized substrate containing one of four different controlled-release fertilizers (Osmocote, Nutricote, Polyon, or Multicote) were monitored for concentrations of Ca, Mg, Fe, Mn, Zn, Cu, and Mo during a 47-week period. Environmental and cultural practices simulated an unheated greenhouse production program typically used for low-nutrient-requiring crops such as azalea and camellia. Leachate concentrations of all nutrients were relatively high during the first 10 to 20 weeks of the study, and then gradually decreased during the remaining portion of the experiment. Few differences were observed among fertilizer types. Of the elements monitored, only Fe and Mn leachate concentrations were above critical levels specified in the Clean Water Act by the U.S. EPA.

Heavy metals are elements that mainly have a 5-22 gr.cm-3 specific gravity. Some of these metals are essential micronutrients for plant growth (Such as Zinc (Zn), Copper (Cu), Manganese (Mn), Nickel (Ni) and Cobalt (Co)). Some other heavy metals, have a high toxicity properties such as Lead (Pb), Cadmium (Cd) and Mercury (Hg). In order to investigate the potential of watercress (Nasturtium officinale) in the uptake of elements from nutrient solutions with different salinities, a factorial experiment was conducted in a completely randomized design with three replications in the greenhouse. In this experiment, different levels of arsenic were zero, 5, 10, 20, 40, 40, 80 and 160 mg.L-1, which were obtained from sodium arsenate source and added to Epstein’s nutrient solution to obtain the mentioned concentrations. The salt concentration of the nutrient solution was 0, 10, 20, 40 and 80 mM which was prepared from sodium chloride source and added to Epstein solution. After making nutrient solutions with different salinity and concentrations, watercress was cultivated. The ANOVA results showed that the interaction of salinity and arsenic levels on the calcium, magnesium, iron, manganese, zinc and copper concentrations in watercress was significant at the level of one percent probability. The highest concentrations of these elements were obtained in the levels without salinity and arsenic and the lowest values were obtained in the 80 mM salinity levels and 160 mg.l-1 arsenic.

ABSTRACT The objective of this study was to evaluate the nutritional status of coriander cultivar Verdão under fertigation depths and pulse and continuous drip irrigation. The experiment was conducted in a protected environment at the Universidade Federal Rural de Pernambuco, Recife, PE, Brazil (8° 1’ 6.50” S, 34° 56’ 46” W and altitude of 6.5 m), in the randomized block design in 2 x 5 factorial scheme, with three repetitions. Treatments consisted of five irrigation depths (40, 60, 80, 100 and 120% of crop evapotranspiration - ETc) and two types of fertigation application (pulse and continuous). At 27 days after sowing, the aerial part of 48 plants per plot was collected for subsequent quantification of nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, manganese, copper and zinc concentrations. Pulse fertigation combined with ETc replacement depths below 100% promoted higher leaf concentrations of phosphorus, sulfur, iron and manganese. Continuous fertigation combined with 100% ETc depth induced sulfur deficiency in the crop and, combined with 40% ETc depth, promoted the highest calcium concentration. Regardless of the type of application, ETc replacement depths from 82.7 and 40% provide adequate leaf concentrations of nitrogen and magnesium, respectively. Regardless of the applied depth, pulse fertigation reduced the leaf concentrations of magnesium.

In Nigeria Arable land covers approximately 745,000km2 of the total land area and at present organic farming is not prevalent, encouraged or facilitated despite its sustainability advantages. The anaerobic digestion process produces two main outputs (biogas and digestate). The digestate when properly harnessed can be used as a substitute for inorganic fertilizer. The digestate retains a high content of organic matter such as Nitrogen, Phosphorous and Potassium (K), as well as a range of other macro-and micronutrients like Calcium, Magnesium, Iron, Manganese, Zinc and ammonium. In this research work, a developed grass shredding machine for the composting of a digestate was evaluated for performance. Preliminary studies were undertaken to determine the liquid absorbability of non-shredded grass vise-visa dry shredded grass, the moisture content of fresh elephant and spear grass. An internal combustion powered shredding machine was developed to shred dry and sieve crushed grasses to be used as absorbent of digestate. The machine was evaluated for performance using different samples of properly dried elephant and spear grass. The shredded grasses samples were mixed with discharge digestate collected from a bio-digester to produce organic fertilizer. The shredding time, machine throughout capacity efficiency, mass of fibre and liquor were determined. The results of performance evaluation with elephant grass sample revealed that an average value of efficiency (90.97%), machine through put capacity (1.225g/sec), shredding time (126.54seconds), percentage loss (8.393%), fibre (288.58g) and liquor (119.83g) were established. Similar result were obtained with spear grass; efficiency (90.50%), machine through-put capacity (1.225g/sec), shredding time 126.54 seconds), percentage loss (8.32%), fibre (294.12g), and liquor (118.85g). The outcome of the results revealed that both solid fertilizer (fibre) and liquid fertilizer (liquor) were extracted from the digestate, and an average mass of 138.86g dried grass can absorb 269.55g of liquid digestate to produce organic fertilizer.

Introduction: Terminalia catappa is a large tropical tree in the lead wood tree family, combretacea. This plant is regarded as a medicinal plant and can be used in the treatment of cough, syphilis, hydropsy, rheumatism, and other infections. Aim: This study assessed the nutritional value of Terminalia catappa and the composition of elements present in the plant fruit. Methods: Proximate analysis was carried out according to food chemistry analytical methods and elements were estimated by atomic absorption and flame spectroscopy respectively. Results: Proximate analysis showed that the fruits contained 81.96% moisture content, 1.47% ash, 0.04% crude fat, 1.11% crude protein, 14.05% carbohydrate, and 1.41% crude fibre. The fruits were found to be good sources of minerals. Sodium (2.1±0.01 mg/100 g), potassium (72.5±1.03 mg/100 g), calcium (320±2.00mg/100g), magnesium (20±2.65 mg/100 g), iron (20±3.0 mg/100 g), manganese (2±0.36 mg/100 g), and zinc (8±1.25 mg/100 g). Conclusion: The results revealed the presence of nutrients such as proteins, carbohydrates, crude fats, crude fibre, moisture, and ash in small amounts. And elements analysis shows that sodium, potassium, calcium, magnesium, iron, manganese, and zinc are in appreciable amount. These constituents are therefore responsible for the biochemical values of Terminalia catappa fruits.

This study deals with the potential use of water stored in a lake formed by Reocín’s old zinc mine, which has become the second most important reservoir in Cantabria, with a flow of 1300 L s−1. The methodology used is based on the hydrogeological and hydrochemical characterization of the area studied. A total of 16 piezometers were installed to monitor the amount and quality of water. Results obtained show a pH close to 8 and iron, manganese, zinc, and sulphate concentrations lower than 0.05 mg L−1, 0.05 mg L−1, 1.063 mg L−1, and 1305.5 mg L−1, respectively. The volume of the water stored in the lake amounts to 34 hm3. Measurements show that Fe, Mn, and Zn concentrations are below the limits acceptable for human consumption, according to the Spanish 0.2, 0.05, and 5.0 mg L−1 standards, respectively, while sulphate greatly exceeds the 250 mg L−1 limit accepted by the norm. Therefore, the water could be apt for human consumption after a treatment appropriate for decreasing the sulphate level by, for example, reverse osmosis, distillation, or ion exchange. Although industrial and energy uses are possible, the lake water could be utilized as a geothermal energy source. The management of the hydric resources generated when a mine is closed could improve the economic and environmental conditions of the zone, with all the benefits it brings about, thus allowing for compensating of the pumping cost that environmental protection entails, creating, at the same time, a new business opportunity for the company that owns the mine.
