Enhancing growth of Chlamydomonas reinhardtii and nutrient removal in diluted primary piggery wastewater by elevated CO2 supply
The coupling of primary piggery wastewater as a culture medium with elevated CO2 aeration is thought to be an economically feasible option for the cultivation of microalgae. However, little information is available regarding the photosynthetic characteristics of microalgae and nutrient removal from wastewater at different CO2 concentrations. It was found that elevated CO2 aeration provided ...

Performance of an optimized nutrient management system for double-cropped wheat-maize rotations in North-Central China
Overapplication of N and P and insufficient supply of K are considered primary reasons for restriction of yield improvement in the North China Plain. Optimized nutrient management practices based on soil testing and yield targets have been developed. Other large scale field experiments have indicated that additional improvement for yield and nutrient use benefits is needed. The objective of this ...

Effect of irrigation with anaerobic baffled reactor effluent on Swiss chard (Beta vulgaris cicla.) yield, nutrient uptake and leaching
The disposal of treated wastewater from an anaerobic baffled reactor (ABR) effluent into water bodies can cause pollution. Treated wastewater management through irrigation of crops has the potential of increasing crop production through nutrient uptake while reducing the risks of environmental pollution. However, this study aimed to investigate the effect of irrigation with ABR effluent on ...

Maximizing Timothy forage yield and quality by balanced nitrogen, phosphorus, and sulfur fertilization
A 3-yr (2005–2007) field experiment was conducted on a Gray Luvisol (Typic Cryoboralf) loam near Star City, SK, Canada, to determine the influence of single and combined annual applications of N, P, and S fertilizers on timothy (Phleum pratense L.) forage dry matter yield (DMY), quality [concentration of crude protein (CP), nitrate N, acid detergent fiber (ADF), neutral detergent fiber (NDF), ...

Sugar industry press mud as alternate organic fertiliser source
Organic materials are added to soil for improving soil physico-chemical properties. In the present study different doses of press mud along with NPK were applied to wheat crop in pot and field experiments. The increasing levels of press mud application improved soil physical conditions like increase in total porosity and reduced bulk density. Organic matter content, NPK, Fe, Mn, Zn and Cu content ...

Vermicomposting of mustard residue and effect of its application on soil and plant nutrients status
Vermicomposting of mustard (Brassica juncea) residue with pretreatments of submergence in water, nutrients (urea and low grade rock phosphate) supplementation, microbial (Bacillus sp., Trichoderma viride and Cellulomonas fimi) inoculation and their combined use with fresh cow dung/slurry improved the quality of vermicomposts with respect to C/N ratio, yield, humus fractions and nutrients content. ...

Restoring Long Term Soil Health in Haiti with Organic Compost
Last summer, we shared results from a research project that was taken on by master’s students at Cranfield University. The students compared the efficiency of SOIL’s organic compost, Konpòs Lakay, to commercial grade chemical fertilizers available on the market. This comparison was used two core Haitian crops: tomato plants and moringa trees. When the preliminary results ...

Multi-temporal variation in water consumption of summer maize as determined by the Water Transformation Dynamical Processes Experimental Device
A better understanding of the multi-temporal variation in evapotranspiration (ET) at different crop growth stages is the key for determining a reasonable irrigation schedule. In this study, a new device known as ‘Water Transformation Dynamical Processes Experimental Device’ (WTDPED) was used to monitor ET for maize under controlled environmental and groundwater conditions, and the ...

Investigation of initial pH effects on growth of an oleaginous microalgae
Chlorella sp. HQ for lipid production and nutrient uptakeUsing microalgae for synchronous biodiesel production and wastewater treatment is a promising technology. The growth, lipid accumulation and nutrient uptake characteristics of an oleaginous microalga Chlorella sp. HQ were evaluated at different initial pH from 5.0 to 11.0. The pH values changed towards neutrality and ended in the range 6.0–9.0 without artificial control. The alkalinity ...

Plant growth and nutrient uptake in treatment wetlands for water with low pollutant concentration
The objective of this study was to determine how macrophytes commonly used in treatment wetlands (TWs) respond to water with low pollutant concentration. We measured pollutant removal efficiency and compared growth and nutrient uptake of five macrophytes in demonstration scale units (volume >40 m3) irrigated by water with pollutant concentrations representative of average urban stormwater ...

Water, why should I pay to fix it?
Water is the essential nutrient for greenhouses, plants, vegetables, fruit, flowers and all living things. However, it is always the last nutrient farmers want to spend money on to accomplish all its benefits. Simple things like bacteria, electrical conductivity, iron, manganese, sulphates, algae, and funguses must be monitored and addressed. If you are not fixing your water, you are leaving a ...

Side-band injection of acidified cattle slurry as starter P-fertilization for maize seedlings
Abstract Accumulation of phosphorus (P) in agricultural soils has caused increasing environmental concerns. Maize cropped for fodder implies return of animal manures rich in nutrients. In addition, starter fertilization with mineral P is used in cold conditions for maize cropping. It was hypothesized that the use of the additional mineral P could be excluded by increased availability of the P ...

Nitrogen mineralization in a pecan ( Carya illinoensis K. Koch)–cotton ( Gossypium hirsutum L.) alley cropping system in the southern United States
Information on temporal and spatial patterns of N mineralization is critical in designing tree-crop mixed systems that could maximize N uptake while minimizing N loss. We quantified N mineralization rates in a pecan (Carya illinoensis K. Koch)–cotton (Gossypium hirsutum L.) alley cropping system in northwestern Florida with (non-barrier) and without tree-crop belowground interactions (barrier ...

Nitrogen fertilization effect on phosphorus remediation potential of three perennial warm-season forages
Warm-season C4 grasses are capable of removing excess soil nutrients because of their high yield potential and nutrient uptake efficiency. Bahiagrass (Paspalum notatum Flügge), limpograss [Hemarthria altissima (Poir.) Stapf & Hubb], and stargrass (Cynodon nlemfuensis Vanderyst), three commonly used pasture grasses in South-Central Florida, were grown to examine the effect of increasing N ...

Plant reduces recycled phosphorus levels with biostimulation - Case Study
Problem A Texas utility struggled with elevated levels of sidestream phosphorus recycled to the treatment plant headworks from the aerobic digesters. The plant had documented increased phosphorus from decant and from downstream centrate, elevating effluent phosphorus and potentially affecting permit compliance. Staff investigated using a biostimulant in the digesters to improve biological ...

Barley yield and nutrient uptake for soil amended with fresh and composted cattle manure
Limited research exists on the long-term effect of fresh (FM) versus composted manure (CM) from beef cattle on barley (Hordeum vulgare L.) yield and nutrient uptake. Barley was grown (1999–2007) as silage on an irrigated clay loam soil in southern Alberta where organic amendments and fertilizer were annually applied for 9 yr in the fall of 1998 to 2006. The treatments were three rates (13, 39, 77 ...

What to know when you are transitioning from HPS to LED
Many growers are looking to switch from HID technology (HPS and MH luminaires) over to LEDs for reasons such as increased energy savings, reduced heat output, longer lifespan and greater spectral efficiencies. And while LEDs can offer many advantages over HID luminaires, there are several things a grower should know before jumping in. Since LEDs can cost 2-3 times more than HID luminaires, ...
